Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements included herein (the "Unaudited Condensed Consolidated Financial Statements") have been prepared by Criteo pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 24, 2023. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal, recurring adjustments) which are, in the opinion of management, necessary to state fairly the results for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the fiscal year. Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses in the condensed consolidated financial statements and accompanying notes. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. Our actual results may differ from these estimates. U.S. GAAP requires us to make estimates and judgments in several areas, including, but not limited to: (1) gross vs net assessment in revenue recognition (2) allowances for credit losses, (3) income taxes, (4) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (5) assumptions used in the valuation of goodwill, intangible assets and leases, (6) assumptions used in the valuation model to determine the fair value of share-based compensation plan, and (7) assumptions surrounding the recognition and valuation of contingent liabilities and losses. There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Accounting Pronouncements Adopted in 2023 No standards were adopted in 2023 which had an impact on the Company's financial statements. Recent Accounting Pronouncements Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s Consolidated Financial Statements upon adoption.

Business Combination and Asset Acquisition [Abstract]
Business acquisitions	Business acquisitions Iponweb On August 1, 2022 (the "Acquisition Date"), the Company, Iponweb Holding Limited, Exezars Limited (a subsidiary of Iponweb Holding Limited and collectively with Iponweb Holding Limited, the “Sellers”), Mr. Ljubisa Bogunovic, in his capacity as trustee of the “IW General Management Trust” and Mr. Boris Mouzykantskii, founder and Chief Executive Officer of Iponweb Holding Limited (the “Founder”) entered into an amended and restated Framework Purchase Agreement (the “FPA”), amending and restating the previously disclosed framework purchase agreement, dated December 22, 2021, which provided for the acquisition of the business of Iponweb Holding Limited (the "Iponweb business"), a market-leading AdTech company with world-class media trading capabilities, by the Company (the “Iponweb Acquisition”). This business combination is composed of an asset purchase of Iponweb intellectual property and other intangible rights and a share purchase of 100% of the share capital and voting rights of nine Iponweb operational legal entities. Purchase price. The purchase price, as per ASC 805, was $290.2 million for the Iponweb business, out of which $61.2 million represents the fair value of the contingent consideration. This contingent consideration is payable in cash to the Sellers in an amount up to $100 million, conditioned upon the achievement of certain net revenue targets by the Iponweb business for the 2022 and 2023 fiscal years. Separate compensation arrangement. The Company transferred Treasury shares with a fair value of $70.2 million to Iponweb's Sellers, subject to lock-up conditions. As these shares are subject to a lock-up period that expires in three installments on each of the first three the $70.2 million fair value was not included in the purchase price consideration above and will be accounted for separately from the business combination as a stock compensation expense. See Note 12 for further discussion. Financing. The acquisition was financed by available cash resources, and in connection with the Iponweb Acquisition, the Company drew down €50.0 million ($51.1 million) for a one-month period on its then-current revolving credit facility (repaid prior to quarter end) to provide additional liquidity. Assets acquired and liabilities assumed. The transaction was accounted for as a business acquisition. The purchase price allocation has been completed. On the Acquisition Date, assets acquired and liabilities assumed by major asset class before purchase price allocation were as follow: Estimated fair values (in millions) Cash and cash equivalents $ 93.3 Trade receivables 100.7 Other current assets 1.1 Technology 90.2 Customer relationships 7.2 Other non-current assets 59.0 Trade Payables (191.5) Other current liabilities (3.1) Other non-current liabilities (54.3) Net assets acquired $ 102.6 Developed technology represents the estimated fair value of the features underlying the Iponweb products as well as the platform providing services to Iponweb customers. Customer relationships represent the estimated fair value of the underlying relationships with Iponweb customers, including the fair value of unbilled and unrecognized contracts yet to be fulfilled. The estimated useful lives of technologies acquired and customer relationships are four In the Iponweb business's opening balance sheet, Criteo recognized a $17.6 million liability related to the Iponweb business's uncertain tax positions in accordance with ASC 740. The Company also recognized a $33.7 million provision in connection with the Iponweb business, accounted for under ASC 450 Contingencies. As part of the Iponweb Acquisition, the Sellers agreed to indemnify Criteo for losses related to certain liabilities, up to an amount of $50.0 million. As such, Criteo has recognized an indemnification asset of $50.0 million which is recorded as part of "Other non-current assets" on the consolidated statement of financial position. Goodwill. The Company has completed the valuation of assets acquired and liabilities assumed as part of the Iponweb Acquisition, based on facts and circumstances that existed as of the Acquisition Date. The excess of the purchase price over the fair value of net assets acquired has been allocated to goodwill. The goodwill of $187.6 million is primarily attributable to synergies expected to be realized from leveraging our technological capabilities and from the existence of an assembled workforce. Acquisition costs. Acquisition related costs of $12.6 million were recorded within general and administrative expenses on the consolidated statements of comprehensive income for the twelve months ended December 31, 2022. In the period ending June 30, 2023, we did not record any acquisition related costs. Impact on profit and loss. The Company's consolidated statements of operations for the six months ended June 30, 2023 include Iponweb's revenues of $54.2 million and pretax income (loss) of $6.7 million. On a pro-forma basis, assuming the Iponweb Acquisition occurred on January 1, 2022, Criteo's consolidated pro-forma revenue and net loss would have been as follows: Three Months Ended Six Months Ended June 30 June 30 June 30 June 30 Revenue $ 468,934 $ 522,039 $ 913,950 $ 1,058,034 Net loss (1,971) (38,406) (14,042) (21,684) The historical consolidated financial information has been adjusted in the pro forma combined financial statements to give the effect to pro forma events that are directly attributable to the business combination and are reasonably estimable. The pro forma information is for informational purposes only and is not indicative of the results of operations that would have been achieved if the Iponweb Acquisition had taken place at the beginning of the Company's fiscal year 2022.

Financial and other income and expenses	Financial and Other Income and Expenses The condensed consolidated statements of income line item “Financial and Other income (expense)” can be broken down as follows: Three Months Ended Six Months Ended June 30, June 30, June 30, June 30, (in thousands) Financial income from cash equivalents $ 1,072 $ 240 $ 2,135 $ 373 Interest and fees (577) (422) (1,063) (969) Foreign exchange gains (losses) (1,003) 16,126 (2,952) 20,589 Discounting impact (1,419) — (2,099) — Other financial income (expense) 75 468 8,954 449 Total Financial and Other income (expense) $ (1,852) $ 16,412 $ 4,975 $ 20,442 The $5.0 million in financial and other income for the six months ended June 30, 2023, were driven by proceeds from disposal of non consolidated investments and financial income from cash equivalents, partially offset by the recognition of a negative impact of foreign exchange reevaluations net of related hedging and the up-front fees amortization, the non-utilization costs, and the financial expense relating to our available Revolving Credit Facility financing, and the accretion of earn-out liability related to Iponweb acquisition. At June 30, 2023, our exposure to foreign currency risk was centralized at Criteo S.A. and hedged using foreign currency swaps or forward purchases or sales of foreign currencies.

Income Taxes	Jun. 30, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Breakdown of Income Taxes The tax provision for interim periods is determined using an estimate of our annual effective tax rate (“AETR”), adjusted for discrete items arising in the period. To calculate our estimated AETR, we estimate our income before taxes and the related tax expense or benefit for the full fiscal year (total of expected current and deferred tax provisions), excluding the effect of significant unusual or infrequently occurring items or comprehensive income items not recognized in the statement of income. Each quarter, we update our estimate of the annual effective tax rate, and if our estimated annual tax rate does change, we make a cumulative adjustment in that quarter. Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, are subject to significant volatility due to several factors, including our ability to accurately predict our income (loss) before provision for income taxes in multiple jurisdictions and the changes in foreign exchange rates. Our effective tax rate in the future will depend on the portion of our profits earned within and outside of France. On October 8, 2021, the Organization for Economic Co-operation and Development (OECD) announced the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting which agreed to a two-pillar solution to address tax challenges arising from digitalization of the economy. On December 20, 2021, the OECD released Pillar Two Model Rules defining the global minimum tax, which calls for the taxation of a minimum rate of 15% for multinational companies with consolidated revenue above €750 million. Various foreign jurisdictions are in the process of enacting legislation to adopt a minimum effective tax rate. The OECD continues to release additional guidance on the two-pillar solution with an implementation anticipated by 2024. We are currently evaluating the potential impact on future periods of the Pillar Two, pending legislative adoption by individual countries. The following table presents provision for income taxes: Six Months Ended June 30, 2023 June 30, 2022 (in thousands) Provision for income tax (expense) benefit $ 3,517 $ (3,293) For the six months ended June 30, 2023 and June 30, 2022, provision for income tax (expense) benefit was $3.5 million and $(3.3) million, respectively. The $3.5 million tax benefit was driven by the loss from operations. The six months ended June 30, 2023 provision for income taxes mainly differs from the nominal standard French rate of 25.0% due to the application of a reduced income tax rate on the majority of the technology royalties income in France.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies Contingencies From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, results of operations, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. The amount of the provisions represents management’s latest estimate of the expected impact. Regulatory matters In November 2018, Privacy International filed a complaint with certain data protection authorities, including France's Commission Nationale de l'Informatique et des Libertés (the "CNIL"), against Criteo and a number of other advertising technology companies, arguing that certain of these companies' practices were not in compliance with the European Union's General Data Protection Regulation ("GDPR"). In January 2020, the CNIL opened a formal investigation. As previously disclosed, the assigned rapporteur issued a report that claimed various GDPR violations and included a proposed financial sanction against Criteo of €60.0 million ($65 million), and on March 16, 2023, the CNIL Sanction Committee conducted a formal hearing. On June 21, 2023, Criteo received notice that the CNIL issued their decision, in which the CNIL retained alleged GDPR violations but reduced the financial sanction against Criteo from the original proposed amount of €60 million ($65 million) to €40 million ($44 million). The decision relates to past matters and does not include any obligation for Criteo to change its current practices. Criteo intends to appeal this decision before the competent courts. The €40 million ($44 million) penalty was applied against the previously accrued liability for loss contingency reflected in our financial statements for the period ended June 30, 2022, which amounted to €60 million ($65 million). Criteo anticipates making the required sanction payment in the third quarter of 2023. Non income tax risks

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements included herein (the "Unaudited Condensed Consolidated Financial Statements") have been prepared by Criteo pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 24, 2023. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal, recurring adjustments) which are, in the opinion of management, necessary to state fairly the results for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the fiscal year. Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses in the condensed consolidated financial statements and accompanying notes. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. Our actual results may differ from these estimates. U.S. GAAP requires us to make estimates and judgments in several areas, including, but not limited to: (1) gross vs net assessment in revenue recognition (2) allowances for credit losses, (3) income taxes, (4) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (5) assumptions used in the valuation of goodwill, intangible assets and leases, (6) assumptions used in the valuation model to determine the fair value of share-based compensation plan, and (7) assumptions surrounding the recognition and valuation of contingent liabilities and losses.
