The condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary to present fairly the results of operations for the interim periods presented.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS Acquisition of Financial Resources Group Investment Services, LLC On January 31, 2023, the Company acquired Financial Resources Group Investment Services, LLC, a broker-dealer and independent branch office, in order to expand its addressable markets and complement organic gro wth. The transaction closed on January 31, 2023 for an initial payment of approximately $140 million with potential contingent payments over the three years following the closing. The Company accounted for the acquisition under the acquisition method of accounting for business combinations. At June 30, 2023, the Company had provisionally allocated $129.7 million of the purchase price to goodwill, $53.5 million to definite-lived intangible assets, $45.4 million to liabilities for contingent consideration, $9.0 million to cash acquired and the remainder to other assets acquired and liabilities assumed as part of the acquisition. The goodwill primarily includes synergies expected to result from combining operations and is deductible for tax purposes. The intangible assets are comprised of $34.7 million of bank relationships and $18.8 million of advisor relationships, which were valued using the income approach and are included in the Advisor and enterprise relationships line item in Note 7 - Goodwill and Other Intangibles, Net . The fair value determination of bank and advisor relationships required the Company to make significant estimates and assumptions related to future net cash flows and discount rates. Other Acquisitions During the six months ended June 30, 2023, the Company also allocated $171.1 million to intangible assets acquired under its Liquidity & Succession solution and as part of the acquisition of Boenning & Scattergood’s Private Client Group on January 31, 2023. These transactions include potential contingent payments of up to $91.6 million, which may become payable over the next five years. The Company has not recognized a liability for these contingent payments as the amounts to be paid will be uncertain until a future measurement date. See Note 7 - Goodwill and Other Intangibles, Net , for additional information.

Fair Value Measurements

Fair Value Measurements	6 Months Ended
Fair Value Measurements	Jun. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Inputs used to measure fair value are prioritized within a three-level fair value hierarchy. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. There have been no transfers of assets or liabilities between these fair value measurement classifications during the six months ended June 30, 2023 or 2022. The Company’s fair value measurements are evaluated within the fair value hierarchy, based on the nature of inputs used to determine the fair value at the measurement date. At June 30, 2023 and December 31, 2022, the Company had the following financial assets and liabilities that are measured at fair value on a recurring basis: Cash Equivalents — The Company’s cash equivalents include money market funds and U.S. government obligations, which are short term in nature with readily determinable values derived from active markets. Cash Equivalents Segregated Under Federal or Other Regulations — The Company’s cash equivalents segregated under federal or other regulations include U.S. treasury bills, which are short term in nature with readily determinable values derived from active markets. Trading Securities and Securities Sold, But Not Yet Purchased — The Company’s trading securities consist of house account model portfolios established and managed for the purpose of benchmarking the performance of its fee-based advisory platforms and temporary positions resulting from the processing of client transactions. The Company uses prices obtained from independent third-party pricing services to measure the fair value of its trading securities. Prices received from the pricing services are validated using various methods including comparison to prices received from additional pricing services, comparison to available quoted market prices and review of other relevant market data including implied yields of major categories of securities. In general, these quoted prices are derived from active markets for identical assets or liabilities. When quoted prices in active markets for identical assets and liabilities are not available, the quoted prices are based on similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. For negotiable certificates of deposit and treasury securities, the Company utilizes market-based inputs, including observable market interest rates that correspond to the remaining maturities or the next interest reset dates. At June 30, 2023 and December 31, 2022, the Company did not adjust prices received from the independent third-party pricing services. Other Assets — The Company’s other assets include: (1) deferred compensation plan assets that are invested in life insurance, money market and other mutual funds, which are actively traded and valued based on quoted market prices; and (2) certain non-traded real estate investment trusts and auction rate notes, which are valued using quoted prices for identical or similar securities and other inputs that are observable or can be corroborated by observable market data. Fractional Shares — The Company’s investment in fractional shares held by customers is reflected in other assets while the related purchase obligation for such shares is reflected in other liabilities. The Company uses prices obtained from independent third-party pricing services to measure the fair value of its investment in fractional shares held by customers and the related repurchase obligation. Prices received from the pricing services are validated using various methods including comparison to prices received from additional pricing services, comparison to available quoted market prices and review of other relevant market data including implied yields of major categories of securities. At June 30, 2023 and December 31, 2022, the Company did not adjust prices received from the independent third-party pricing services. Accounts Payable and Accrued Liabilities — The Company’s accounts payable and accrued liabilities include contingent consideration liabilities that are measured using Level 3 inputs. Level 3 Recurring Fair Value Measurements The Company determines the fair value for its contingent consideration obligations using a scenario-based approach whereby the Company assesses the forecasted assets under management or number of future transactions. The contingent payments are estimated by applying assumptions, including forecasted volatility and discount rates, to the forecasted payments to calculate the fair value as of the valuation date. The Company evaluates the underlying projections and other related factors used in determining fair value each period and makes updates when there have been significant changes in management’s expectations.

The following table presents amounts outstanding and available under the Company’s external lines of credit at June 30, 2023 (in millions): Description Borrower Maturity Date Outstanding Available Senior secured, revolving credit facility LPL Holdings, Inc.

The Credit Agreement subjects the Company to certain financial and non-financial covenants. As of June 30, 2023, the Company was in compliance with such covenants. Parent Revolving Credit Facility Borrowings under the revolving credit facility bear interest at a rate per annum ranging from 125 to 175 basis points over SOFR plus 10 basis points or 25 to 75 basis points over the alternate base rate (the greatest of (i) the NYFRB Rate plus 1/2 of 1%, (ii) the Prime Rate and (iii) the Adjusted Term SOFR Rate for a one month Interest Period plus 1%, each as defined in the Credit Agreement) depending on the Consolidated Secured Debt to Consolidated EBITDA Ratio (as defined in the Credit Agreement). On July 18, 2023, LPLH amended its revolving credit facility to, among other things, increase the maximum borrowing from $1.0 billion to $2.0 billion. Broker-Dealer Revolving Credit Facility On August 4, 2022, LPL Financial, the Company’s broker-dealer subsidiary, entered into a committed senior unsecured revolving credit facility that matures on August 3, 2023 and allows for a maximum borrowing of up to $1.0 billion. Borrowings under the credit facility bear interest at a rate per annum equal to 1.25% per annum plus the greatest of (i) SOFR plus 0.10%, (ii) the effective federal funds rate and (iii) the overnight bank funding rate, in each case, as such rate is administered or determined by the Federal Reserve Bank of New York from time to time. In connection with the credit facility, LPL Financial incurred $1.9 million in costs, which were capitalized as debt issuance costs in the condensed consolidated statements of financial condition. The bro ker-dealer credit agreement subjects LPL Financial to certain financial and non-financial covenants. LPL Financial was in compliance with such covenants as of June 30, 2023. On July 18, 2023, LPL Financial renewed its revolving credit facility and extended the maturity date to July 16, 2024. Other External Lines of Credit LPL Financial maintained five uncommitted lines of credit as of June 30, 2023. Two o f the lines have unspecified limits, which are primarily dependent on LPL Financial’s ability to provide sufficient collateral. T he other three lines have a total limit of $200.0 million, which allow for uncollateralized borrowings. There were no b alances outstanding under these lines at June 30, 2023 or December 31, 2022.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended
Commitments and Contingencies	Jun. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Service and Development Contracts The Company is party to certain long-term contracts for systems and services that enable back-office trade processing and clearing for its product and service offerings. Guarantees The Company occasionally enters into contracts that contingently require it to indemnify certain parties against third-party claims. The terms of these obligations vary and, because a maximum obligation is not explicitly stated, the Company has determined that it is not possible to make an estimate of the amount that it could be obligated to pay under such contracts. LPL Financial provides guarantees to securities clearing houses and exchanges under their standard membership agreements, which require a member to guarantee the performance of other members. Under these agreements, if a member becomes unable to satisfy its obligations to the clearing houses and exchanges, all other members would be required to meet any shortfall. The Company’s liability under these arrangements is not quantifiable and could exceed the cash and securities it has posted as collateral. However, the potential requirement for the Company to make payments under these agreements is remote. Accordingly, no liability has been recognized for these transactions. Loan Commitments From time to time, LPL Financial makes loans to advisors and enterprises, primarily to newly recruited advisors and enterprises to assist in the transition process, which may be forgivable. Due to timing differences, LPL Financial may make commitments to issue such loans prior to actually funding them. These commitments are generally contingent upon certain events occurring, including but not limited to the advisor or enterprise joining LPL Financial. LPL Financial had no significant unfunded loan commitments at June 30, 2023 or December 31, 2022. Legal and Regulatory Matters The Company is subject to extensive regulation and supervision by U.S. federal and state agencies and various self-regulatory organizations. The Company and its advisors periodically engage with such agencies and organizations, in the context of examinations or otherwise, to respond to inquiries, informational requests and investigations. From time to time, such engagements result in regulatory complaints or other matters, the resolution of which has in the past and may in the future include fines, customer restitution and other remediation. Assessing the probability of a loss occurring and the timing and amount of any loss related to a legal proceeding or regulatory matter is inherently difficult. While the Company exercises significant and complex judgments to make certain estimates presented in its condensed consolidated financial statements, there are particular uncertainties and complexities involved when assessing the potential outcomes of legal proceedings and regulatory matters. The Company’s assessment process considers a variety of factors and assumptions, which may include: the procedural status of the matter and any recent developments; prior experience and the experience of others in similar matters; the size and nature of potential exposures; available defenses; the progress of fact discovery; the opinions of counsel and experts; or the potential opportunities for settlement and the status of any settlement discussions. The Company monitors these factors and assumptions for new developments and re-assesses the likelihood that a loss will occur and the estimated range or amount of loss, if those amounts can be reasonably determined. The Company has established an accrual for those legal proceedings and regulatory matters for which a loss is both probable and the amount can be reasonably estimated. In October 2022, the Company received a request for information from the SEC in connection with an investigation of the Company’s compliance with records preservation requirements for business-related electronic communications stored on personal devices or messaging platforms that have not been approved by the Company. The Company intends to cooperate fully with the SEC’s inquiry. The Company has estimated that it is reasonably possible that it could incur losses as a result of this request; however, the Company cannot estimate a possible loss or range of loss at this time. At this time, the Company does not believe that this request will have a material adverse effect on its results of operations, financial position or cash flows. Third-Party Insurance The Company maintains third-party insurance coverage for certain potential legal proceedings, including those involving certain client claims. With respect to such client claims, the estimated losses on many of the pending matters are less than the applicable deductibles of the insurance policies. Self-Insurance The Company has self-insurance for certain potential liabilities through the Captive Insurance Subsidiary. Liabilities associated with the risks that are retained by the Company are not discounted and are estimated by considering, in part, historical claims experience, severity factors, and actuarial assumptions and estimates. The estimated accruals for these potential liabilities could be significantly affected if future occurrences and claims differ from such assumptions and historical trends, so there are particular complexities and uncertainties involved when assessing the adequacy of loss reserves for potential liabilities that are self-insured. Self-insurance liabilities are included in accounts payable and accrued liabilities in the condensed consolidated statements of financial condition. Self-insurance related charges are included in other expense in the condensed consolidated statements of income. The following table provides a reconciliation of the beginning and ending balances of self-insurance liabilities for the periods presented (in thousands): Six Months Ended June 30, 2023 2022 Beginning balance — January 1 $ 74,071 $ 67,152 Losses incurred 18,093 18,251 Losses paid (10,424) (11,657) Ending balance — June 30 $ 81,740 $ 73,746 Other Commitments As of June 30, 2023, the Company had approximately $472.0 million of client margin loans that were collateralized with securities having a fair value of approximately $660.8 million that LPL Financial can repledge, loan or sell. Of these securities, approximately $249.9 million were client-owned securities pledged to the Options Clearing Corporation as collateral to secure client obligations related to options positions. As of June 30, 2023, there were no restrictions that materially limited the Company’s ability to repledge, loan or sell the remaining $410.9 million of client collateral. Investment securities on the condensed consolidated statements of financial condition include $4.5 million of trading securities pledged to the Options Clearing Corporation at both June 30, 2023 and December 31, 2022, and $19.9 million of trading securities pledged to the National Securities Clearing Corporation at both June 30, 2023 and December 31, 2022.

The 2021 Plan serves as the successor to the Company’s 2010 Omnibus Equity Incentive Plan (the “2010 Plan”). Following the adoption of the 2021 Plan, the Company is no longer making grants under the 2010 Plan, and the 2021 Plan is the only plan under which equity awards are granted. However, awards previously granted under the 2010 Plan will remain outstanding until vested, exercised or forfeited, as applicable. There were 17,754,197 shares authorized for grant under the 2021 Plan and 12,818,635 shares remaining available for future issuance at June 30, 2023.

Earnings per Share	Jun. 30, 2023
Earnings Per Share [Abstract]
Earnings per Share	EARNINGS PER SHARE Basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased to include the number of additional shares of common stock that would have been outstanding if dilutive potential shares of common stock had been issued. The calculation of basic and diluted earnings per share for the periods noted was as follows (in thousands, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Net income $ 285,520 $ 160,545 $ 624,404 $ 294,289 Basic weighted-average number of shares outstanding 77,234 79,947 77,988 79,961 Dilutive common share equivalents 960 1,463 1,095 1,532 Diluted weighted-average number of shares outstanding 78,194 81,410 79,083 81,493 Basic earnings per share $ 3.70 $ 2.01 $ 8.01 $ 3.68 Diluted earnings per share $ 3.65 $ 1.97 $ 7.90 $ 3.61 The computation of diluted earnings per share excludes stock options, warrants and stock units that are anti-dilutive. For the three months ended June 30, 2023 and 2022, stock options, warrants and stock units representing common share equivalents of 208,654 shares and 142 shares, respectively, were anti-dilutive. For the six months ended June 30, 2023 and 2022, stock options, warrants and stock units representing common share equivalents of 107,544 shares and 2,001 shares, respectively, were anti-dilutive.

Broker-Dealer [Abstract]
Net Capital and Regulatory Requirements	NET CAPITAL AND REGULATORY REQUIREMENTS The Company’s broker-dealer subsidiaries are subject to the SEC’s Uniform Net Capital Rule (Rule 15c3-1 under the Exchange Act of 1934, as amended), which requires the maintenance of minimum net capital. The net capital rules also provide that a broker-dealer’s capital may not be withdrawn if the resulting net capital would be less than minimum requirements. Additionally, certain withdrawals require the approval of the SEC and the Financial Industry Regulatory Authority (“FINRA”) to the extent they exceed defined levels, even though such withdrawals would not cause net capital to be less than minimum requirements. Net capital and the related net capital requirement may fluctuate on a daily basis. The following table presents the net capital position of the Company’s primary broker-dealer subsidiary (in thousands): June 30, 2023 LPL Financial LLC Net capital $ 279,982 Less: required net capital 16,154 Excess net capital $ 263,828 The Company’s subsidiary, PTC, also operates in a highly regulated industry and is subject to various regulatory capital requirements. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have substantial monetary and non-monetary impacts on PTC’s operations. As of June 30, 2023, LPL Financial an d PTC met all capital adequacy requirements to which they were subject.

Concentration Risk Credit Risk Financial Instruments Off Balance Sheet Risk [Abstract]
Financial Instruments with Off-Balance-Sheet Credit Risk and Concentrations of Credit Risk	FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET CREDIT RISK AND CONCENTRATIONS OF CREDIT RISK LPL Financial may offer loans to new and existing advisors and enterprises to facilitate their relationship with LPL Financial, transition to LPL Financial’s platform or fund business development activities. LPL Financial may incur losses if advisors or enterprises do not fulfill their obligations with respect to these loans. To mitigate this risk, LPL Financial evaluates the performance and creditworthiness of the advisor or enterprise prior to offering repayable loans. LPL Financial’s client securities activities are transacted on either a cash or margin basis. In margin transactions, LPL Financial extends credit to the advisor’s client, subject to various regulatory and internal margin requirements, which is collateralized by cash and securities in the client’s account. As clients write options contracts or sell securities short, LPL Financial may incur losses if the clients do not fulfill their obligations and the collateral in the clients’ accounts is not sufficient to fully cover losses that clients may incur from these strategies. To control this risk, LPL Financial monitors margin levels daily and clients are required to deposit additional collateral, or reduce positions, when necessary. LPL Financial is obligated to settle transactions with brokers and other financial institutions even if its advisors’ clients fail to meet their obligation to LPL Financial. Clients are required to complete their transactions on the settlement date, generally two business days after the trade date. If clients do not fulfill their contractual obligations, LPL Financial may incur losses. In addition, the Company occasionally enters into certain types of contracts to fulfill its sale of when-issued securities. When-issued securities have been authorized but are contingent upon the actual issuance of the security. LPL Financial has established procedures to reduce this risk by generally requiring that clients deposit cash or securities into their account prior to placing an order. LPL Financial may at times hold equity securities on both a long and short basis that are recorded on the condensed consolidated statements of financial condition at market value. While long inventory positions represent LPL Financial’s ownership of securities, short inventory positions represent obligations of LPL Financial to deliver specified securities at a contracted price, which may differ from market prices prevailing at the time of completion of the transaction. Accordingly, both long and short inventory positions may result in losses or gains to LPL Financial as market values of securities fluctuate. To mitigate the risk of losses, long and short positions are marked-to-market daily and are continuously monitored by LPL Financial.
