Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements of IHS Markit have been prepared on substantially the same basis as our annual consolidated financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended November 30, 2020. In our opinion, these condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented, and such adjustments are of a normal, recurring nature. Our business has seasonal aspects. Our first quarter generally has our lowest quarterly levels of revenue and profit. We also experience event-driven seasonality in our business. For instance, CERAWeek, an annual energy conference, is typically held in the second quarter of each year; however, this event was cancelled in 2020 due to the COVID-19 pandemic, and we held this conference virtually in March 2021. Another example is the biennial release of the Boiler Pressure Vessel Code (“BPVC”) engineering standard, which generates revenue for us predominantly in the third quarter of every other year. The most recent BPVC release was in the third quarter of 2019. The preparation of financial statements in conformity with U.S. GAAP requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well the reported amounts of revenue and expense during the reporting period. We have considered the impact of the COVID-19 pandemic in determining our estimates. Actual results could differ from those estimates. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, which replaces the existing incurred loss impairment model with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The adoption of this standard in the first quarter of 2021 did not have a significant impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, which removes Step 2 from the goodwill impairment test. The adoption of this standard in the first quarter of 2021 did not have a significant impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, which addresses the accounting for implementation costs associated with a hosted service. The standard provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. The adoption of this standard in the first quarter of 2021 did not have a significant impact on our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, which enhances and simplifies various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, and interim-period accounting for enacted changes in tax law. The standard will be effective for us in the first quarter of our fiscal year 2022, although early adoption is permitted. We do not expect that the adoption of this ASU will have a significant impact on our consolidated financial statements.

Business Combinations [Abstract]
Business Combinations and Divestitures	Business Combinations and Divestitures S&P Global Inc. On November 29, 2020, we, S&P Global Inc., a New York corporation (“S&P Global”), and Sapphire Subsidiary, Ltd., a Bermuda exempted company limited by shares and a wholly-owned subsidiary of S&P Global (“Merger Sub”), entered into an agreement and plan of merger, which was subsequently amended on January 20, 2021, pursuant to which Merger Sub will merge with and into IHS Markit, with IHS Markit surviving such merger as a wholly-owned, direct subsidiary of S&P Global (the “merger”). The merger intends to bring together a unique portfolio of highly complementary assets, as well as innovation and technology capability to accelerate growth and enhance value creation. At the completion of the merger, each IHS Markit share that is issued and outstanding (other than dissenting shares and shares held by IHS Markit in treasury) will be converted into the right to receive 0.2838 fully paid and nonassessable shares of S&P Global common stock, and, if applicable, cash in lieu of fractional shares, without interest, and less any applicable withholding taxes. If the merger is completed, IHS Markit shares will cease to be listed on the New York Stock Exchange and IHS Markit shares will be deregistered under the Securities Exchange Act. The merger was approved by IHS Markit and S&P Global shareholders on March 11, 2021, but is still subject to antitrust and regulatory approval requirements, as well as other customary closing conditions. CME joint venture. In January 2021, we signed an agreement to enter into a 50/50 joint venture arrangement with shared control with CME Group to combine our post-trade services into a new joint venture. The new company will include trade processing and risk mitigation operations and will incorporate CME’s optimization businesses (Traiana, TriOptima, and Reset) and our MarkitSERV business. Through the combination, we intend to increase operating efficiencies and be better able to service clients with enhanced platforms and services for OTC markets across interest rate, FX, equity, and credit asset classes. We expect the deal to close in the summer of 2021, subject to customary antitrust and regulatory approvals and other customary closing conditions. The following table provides the components of MarkitSERV assets and liabilities (previously included in our Financial Services segment) treated as held for sale as of February 28, 2021 (in millions): Current assets $ 34.8 Property and equipment 62.0 Intangible assets 397.6 Goodwill 362.6 Assets held for sale $ 857.0 Deferred revenue $ (7.3) Other current liabilities (14.4) Deferred income taxes (78.1) Liabilities held for sale $ (99.8) Gen II. In December 2020, we acquired a 13 percent interest in Gen II Fund Services for $150 million as part of a joint venture with General Atlantic and Hg Capital. We expect that this investment will drive revenue synergies between the joint venture and our Private Markets solutions across private credit, private equity, and data and analytics businesses. We are accounting for this investment using the equity method of accounting. Cappitech. In December 2020, we acquired Cappitech Regulation Ltd., a Tel-Aviv based technology company providing regulatory reporting solutions on behalf of its clients to regulators, trade repositories, and affiliates, allowing customers to efficiently monitor the transaction reporting taking place across multiple jurisdictions. Cappitech’s advanced technology provides a scalable platform that we expect to combine with our other offerings in the Financial Services segment. We acquired Cappitech for upfront consideration of $47 million, net of cash acquired, with an additional earnout based on a three-year performance period, which we currently estimate at $57 million. The earnout liability is recorded within other accrued expenses and other liabilities in the condensed consolidated balance sheets. The purchase price allocation for this acquisition is still preliminary and may change upon completion of the determination of fair value of assets acquired and liabilities assumed. Aerospace & Defense divestiture. In December 2019, we completed the sale of our Aerospace & Defense (“A&D”) business line to Montagu Private Equity for approximately $466 million. The A&D assets were previously included in our Transportation segment. We recognized a gain of approximately $372 million on the sale. The gain is included in other expense (income), net, in the condensed consolidated statements of operations. automotiveMastermind equity interests acquisition . In September 2017, we acquired automotiveMastermind (“aM”), a leading provider of predictive analytics and marketing automation software for the automotive industry. We purchased approximately 78 percent of aM at that time. In exchange for the remaining 22 percent of aM, we issued equity interests in aM’s immediate parent holding company to aM’s founders and certain employees. We agreed to pay cash to acquire the interests over the next five years based on put/call provisions that tie the valuation to underlying adjusted EBITDA performance of aM. Since the purchase of the remaining 22 percent of the business requires continued service of the founders and employees, we are accounting for the arrangement as compensation expense that is remeasured based on changes in the fair value of the equity interests. We have classified this expense as acquisition-related costs within the condensed consolidated statements of operations and we have classified the associated accrued liability within other liabilities in the condensed consolidated balance sheets. In November 2019, the option holders exercised the put provision on 62.5 percent of their remaining 22 percent interest in the business for $75.9 million in cash, which we paid in December 2019. We estimate the compensation expense associated with the remaining equity interests to be approximately $60 to $65 million, of which approximately $40.7 million has been recognized as of February 28, 2021, with the remaining amount to be recognized through September 2022.

Revenue

Revenue	Feb. 28, 2021
Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	Revenue We disaggregate our revenue by segment (as described in Note 16) and by transaction type according to the following categories: • Recurring fixed revenue represents revenue generated from contracts specifying a relatively fixed fee for services delivered ov er the life of the contract. The initial term of these contracts is typically annual (with some longer-term arrangements) and non-cancellable for the term of the subscription, and may contain provisions for minimum monthly payments. The fixed fee is typically paid annually or more periodically in advance. These contracts typically consist of subscriptions to our various information offerings and software maintenance, which provide continuous access to our platforms and associated data over the contract term. Subscription revenue is usually recognized ratably over the contract term or, for term-based software license arrangements, annually on renewal. • Recurring variable revenue represents revenue from contracts that specify a fee for services, which is typically not fixed. The variable fee is usually paid monthly in arrears. Recurring variable revenue is based on, among other factors, the number of trades processed, assets under management, or the number of positions we value, and revenue is recognized based on the specific factor used (e.g., for usage-based contracts, we recognize revenue in line with usage in the period). Most of these contracts have an initial term ranging from one to five years, with auto-renewal periods thereafter. Recurring variable revenue was derived entirely from the Financial Services segment for all periods presented. • Non-recurring revenue represents consulting, services, single-document product sales, perpetual license sales and associated services, conferences and events, and advertising. Revenue for services and other non-recurring revenue is recognized upon completion of the associated performance obligation. The following table presents our revenue by transaction type (in millions): Three months ended February 28/29, 2021 2020 Recurring fixed revenue $ 825.6 $ 804.1 Recurring variable revenue 172.9 146.8 Non-recurring revenue 121.4 129.9 Total revenue $ 1,119.9 $ 1,080.8 Our customer contracts may include multiple performance obligations; for example, we typically sell software licenses with maintenance and other associated services. For these transactions, we recognize revenue based on the relative fair value to the customer of each performance obligation as each performance obligation is completed. We record a receivable when a customer is billed or when revenue is recognized prior to billing a customer. Contract assets include unbilled amounts for multi-year customer contracts where payment is not yet due and where services have been provided up-front but have not yet been billed. Contract assets were approximately $11.4 million as of February 28, 2021 and $19.3 million as of November 30, 2020, and are recorded in accounts receivable, net, in the condensed consolidated balance sheets. Contract liabilities primarily include our obligations to transfer goods or services for which we have received consideration (or an amount of consideration is due) from the customer. Billings represent amounts that were paid in advance or due from customers. We record our contract liabilities as deferred revenue in the condensed consolidated balance sheets. The following table provides a reconciliation of our contract liabilities as of February 28, 2021 (in millions): Balance at November 30, 2020 $ 886.2 Billings 1,016.6 Revenue recognized (845.7) Divestiture activity (7.3) Balance at February 28, 2021 $ 1,049.8 We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to exceed one year. Certain sales commission programs are designed to promote the sale of products and services to new customers, and we therefore defer the incremental costs related to these programs over the expected customer life related to those products underlying the contracts. We record these expenses as selling, general and administrative expense within the condensed consolidated statements of operations.

Leases [Abstract]
Lessee, Operating Leases	Leases We utilize operating leases for our various workplaces worldwide, and we also utilize operating leases for our data centers. These leases have remaining terms ranging from one to 12 years, many of which include renewal and early termination options. As of February 28, 2021, we have not considered extension and early termination options in our calculation of the right-of-use (“ROU”) assets and lease liabilities because we do not believe that it is reasonably certain that we will exercise those options. We do not have any significant finance leases. We determine if an arrangement is a lease at inception. We consider any contract where there is an identified asset that we have the right to control in determining whether the contract contains a lease. ROU assets represent our right to use the underlying assets for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As our operating leases do not provide an implicit rate, we use an incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. We calculate our incremental borrowing rates by extrapolating our current unsecured bond portfolio across the maturity ladder and adjusting the resultant corporate rate for the estimated spread for a secured borrowing and for foreign currencies, as appropriate. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Operating lease transactions are included in operating lease right-of-use assets, net, and current and non-current operating lease liabilities in the condensed consolidated balance sheets. The following table presents lease cost, cash paid for amounts included in the measurement of lease liabilities, the weighted-average remaining lease term, and the weighted-average discount rate for our operating leases for the three months ended February 28, 2021 and February 29, 2020 (in millions): Three months ended February 28/29, 2021 2020 Lease cost: Operating lease cost $ 14.9 $ 18.9 Variable lease cost $ 2.0 $ 1.7 Other information: Cash paid for amounts included in the measurement of lease liabilities: Operating cash outflows from operating leases $ 17.8 $ 15.8 As of February 28, 2021: Weighted-average remaining lease term 7.8 years Weighted-average discount rate 1.9 % As of February 28, 2021, maturities of operating lease liabilities under non-cancellable arrangements were as follows (in millions): Year Amount Remainder of 2021 $ 53.5 2022 59.9 2023 50.3 2024 44.9 2025 38.3 Thereafter 135.4 Total future minimum operating lease payments 382.3 Imputed interest (27.3) Total operating lease liability $ 355.0

On November 29, 2019, we entered into a $1.25 billion senior unsecured revolving credit agreement (“2019 revolving facility”). Subject to certain conditions, the 2019 revolving facility may be expanded by up to an aggregate of $750 million in additional commitments. Borrowings under the 2019 revolving facility mature in November 2024. The interest rates for borrowings under the 2019 revolving facility are the applicable LIBOR plus a spread of 1.00 percent to 1.625 percent, depending upon our corporate credit rating. A commitment fee on any unused balance is payable periodically and ranges from 0.10 percent to 0.25 percent based upon our corporate credit rating. We had approximately $1.3 million of outstanding letters of credit under the 2019 revolving facility as of February 28, 2021, which reduced the available borrowing under the facility by an equivalent amount. 2019 credit agreement. In September 2019, we entered into a 364-day credit agreement (the “2019 credit agreement”) for a term loan credit facility in an aggregate principal amount of $250.0 million. In April 2020, we amended the 2019 credit agreement to extend the term through April 2021. The interest rate for borrowing under the 2019 credit agreement is the applicable LIBOR plus a spread of 1.00 percent. The 2019 revolving facility and the 2019 credit agreement are subject to certain financial and other covenants, including a maximum Leverage Ratio and a minimum Interest Coverage Ratio, which is defined as the ratio of Consolidated EBITDA to Consolidated Interest Expense, as such terms are defined in the agreements. As of February 28, 2021, we had approximately $227.0 million of outstanding borrowings under the 2019 revolving facility at a current annual interest rate of 1.36 percent and $250.0 million of outstanding borrowings under the 2019 credit agreement at a current weighted average annual interest rate of 1.14 percent. Senior Unsecured Notes. All of our senior unsecured notes (“Senior Notes”) are unsecured and bear interest at a fixed rate payable semiannually. The Senior Notes were issued in registered offerings under the Securities Act or in offerings not subject to the registration requirements of the Securities Act, and all the Senior Notes have been admitted for trading to the official list of The International Stock Exchange in the Channel Islands. The indentures governing the Senior Notes all provide that, at the option of the respective holders of the Senior Notes, we may be required to purchase all or a portion of such Senior Notes upon occurrence of a change of control triggering event as defined in the respective indentures, at a price equal to 101 percent of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. All the indentures also contain (i) covenants that limit our ability to, among other things, incur or create liens and enter into sale and leaseback transactions, (ii) covenants that limit our ability to consolidate or merge with another entity or to sell all or substantially all of our assets to another entity, and (iii) customary default provisions. As of February 28, 2021, we were in compliance with all of our debt covenants. We have classified short-term debt based on scheduled loan payments and intended repayments on our revolving facility based on expected cash availability over the next 12 months. The carrying value of our variable rate debt instruments approximate their fair value because of the variable interest rates associated with those instruments. The fair values of the senior notes were measured using observable inputs in markets that are not active; consequently, we have classified those notes within Level 2 of the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Our business is exposed to various market risks, primarily foreign currency risk. We utilize derivative instruments to help us manage this risk. We do not hold or issue derivatives for speculative purposes. To mitigate foreign currency exposure, we utilize short-term foreign currency forward contracts that manage market risks associated with fluctuations in balances that are denominated in currencies other than the local functional currency. We account for these forward contracts at fair value and recognize the associated realized and unrealized gains and losses in other expense (income), net, since we have not designated these contracts as hedges for accounting purposes. The notional amount of these outstanding foreign currency forward contracts was $418.7 million and $342.3 million as of February 28, 2021 and November 30, 2020, respectively. Since our derivative instruments are not listed on an exchange, we have evaluated fair value by reference to similar transactions in active markets; consequently, we have classified all of our derivative instruments within Level 2 of the fair value measurement hierarchy. As of February 28, 2021, and November 30, 2020, we had assets of $2.1 million and $2.5 million, respectively, which were classified within other current assets, and we had liabilities of $0.6 million and $0.4 million, respectively, which were classified within other accrued expenses and other liabilities.

Income Taxes	Income TaxesOur effective tax rate is estimated based upon the effective tax rate expected to be applicable for the full year.Our effective tax rate for the three months ended February 28, 2021 was 17 percent, compared to 1 percent for the three months ended February 29, 2020. The low 2020 tax rate is primarily due to excess tax benefits on stock-based compensation of approximately $64 million and the tax-efficient divestiture of the A&D business line (U.K. share sales are exempt from tax) of approximately $29 million. The 2021 tax rate includes excess tax benefits on stock-based compensation of approximately $23 million, partially offset by U.S. minimum tax of approximately $19 million.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, in the ordinary course of our business, we are involved in various legal, regulatory or administrative proceedings, lawsuits, government investigations, and other claims, including employment, commercial, intellectual property, and environmental, safety, and health matters. In addition, we may receive routine requests for information from governmental agencies in connection with their regulatory or investigatory authority or from private third parties pursuant to valid court orders or subpoenas. We review such proceedings, lawsuits, investigations, claims, and requests for information and take appropriate action as necessary. At the present time, we can give no assurance as to the outcome of any such pending proceedings, lawsuits, investigations, claims, or requests for information and we are unable to determine the ultimate resolution of or provide a reasonable estimate of the range of possible loss attributable to these matters or the effect they may have on us. However, we do not expect the outcome of such proceedings, lawsuits, claims, or requests for information to have a material adverse effect on our results of operations or financial condition. We have defended and will continue to vigorously defend ourselves in all matters. As of March 22, 2021, nine complaints had been filed by purported shareholders of IHS Markit or S&P Global relating to our proposed merger with S&P Global. Eight of these actions have been voluntarily dismissed. The pending action is captioned Adam Snitkoff v. Marco Alvera, et al., Case No. 650576/2021 (N.Y. Sup. Ct.), filed in the Supreme Court of the State of New York, County of New York (the “Snitkoff Action”). The complaint in the Snitkoff Action names S&P Global and the members of the S&P board as well as IHS Markit as defendants, and it generally asserts state common law claims for breaches of fiduciary duty against the members of the S&P Global board, failure to disclose certain information in the version of the joint proxy statement/prospectus filed by S&P Global with the SEC on January 22, 2021 against all defendants, and aiding and abetting breaches of fiduciary duty against IHS Markit. The Snitkoff Action complaint seeks, among other relief, declaratory relief, an order requiring corrective disclosures, compensatory or rescissory damages, and attorneys’ and experts’ fees. The plaintiff in the Snitkoff Action has filed a stipulation of discontinuance with prejudice following the issuance of certain additional disclosures issued by S&P Global, which is pending court approval. IHS Markit believes the claims asserted in the complaint are without merit.

This October 2019 share repurchase program does not obligate us to repurchase any set dollar amount or number of shares and may be modified, suspended, or terminated at any time without prior notice. Under the repurchase program, we are authorized to repurchase our common shares on the open market from time to time, in privately negotiated transactions, or through accelerated share repurchase agreements, subject to availability of common shares, price, market conditions, alternative uses of capital, and applicable regulatory requirements, at management’s discretion. As of February 28, 2021, we had $1.6 billion remaining available to repurchase under the program. The merger agreement with S&P Global restricts our ability to purchase our shares and therefore our share repurchase program is currently suspended through November 2021, other than for the repurchase of shares associated with tax withholding requirements for share-based compensation. In August 2016, our Board of Directors separately authorized, subject to applicable regulatory requirements, the repurchase of our common shares surrendered by employees in an amount equal to the exercise price, if applicable, and statutory tax liability associated with the vesting of their equity awards, for which we pay the statutory tax on behalf of the employee and forgo receipt of the exercise price of the award from the employee, if applicable. In December 2019, we funded a $500 million accelerated share repurchase (“ASR”) agreement, which terminated in February 2020. We received a total of 6.491 million shares in connection with the ASR. Dividends Our Board of Directors approved a quarterly cash dividend of $0.20 per share during the first quarter of 2021, compared to a quarterly cash dividend of $0.17 per share during the first quarter of 2020. Employee Benefit Trust (EBT) Shares We have approximately 25.2 million outstanding common shares that are held by the Markit Group Holdings Limited Employee Benefit Trust. The trust is under our control using the variable interest entity model criteria; consequently, we have consolidated and classified the trust shares as treasury shares within our condensed consolidated balance sheets.
