Accounting Policies [Abstract]
Accounting Estimates	Accounting Estimates Management is required to make certain estimates and assumptions during the preparation of the consolidated financial statements in accordance with GAAP. These estimates and assumptions impact the reported amount of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amount of net earnings during any period. Actual results could differ from those estimates. Significant estimates underlying the accompanying consolidated financial statements include: the recoverability of long-lived assets, goodwill and intangible assets; the determination of income taxes payable and deferred income taxes, including related valuation allowances; fair value of assets acquired in a business combination; litigation accruals; contract assets; various other allowances, reserves and accruals; assumptions related to the determination of stock-based compensation; and the determination of right-of-use assets and lease liabilities. The Company considered the impact of the current economic conditions, including interest rates and inflation on the assumptions and estimates used when preparing its consolidated financial statements including, but not limited to, the allowance for doubtful accounts, valuation allowances, contract asset, and the recoverability of long-lived assets, goodwill and intangible assets. These assumptions and estimates may change as new events occur and additional information is obtained. If economic conditions worsen, such future changes may have an adverse impact on the Company's results of operations, financial position and liquidity.
Certain Risks and Concentrations	Certain Risks and Concentrations LendingTree's business is subject to certain risks and concentrations including dependence on third-party technology providers, exposure to risks associated with online commerce security and fraud. Financial instruments, which potentially subject the Company to concentration of credit risk at June 30, 2024, consist primarily of cash and cash equivalents and accounts receivable, as disclosed in the consolidated balance sheet. Cash and cash equivalents are in excess of Federal Deposit Insurance Corporation insurance limits, but are maintained with quality financial institutions of high credit. The Company requires certain Network Partners to maintain security deposits with the Company, which, in the event of non-payment, would be applied against any accounts receivable outstanding. Due to the nature of the mortgage lending industry, interest rate fluctuations may negatively impact future revenue from the Company's marketplace. Lenders and lead purchasers participating on the Company's marketplace can offer their products directly to consumers through brokers, mass marketing campaigns or through other traditional methods of credit distribution. These lenders and lead purchasers can also offer their products online, either directly to prospective borrowers, through one or more online competitors, or both. If a significant number of potential consumers are able to obtain loans and other products from Network Partners without utilizing the Company's services, the Company's ability to generate revenue may be limited. Because the Company does not have exclusive relationships with the Network Partners whose loans and other financial products are offered on its online marketplace, consumers may obtain offers from these Network Partners without using its service. Other than a support services office in India, the Company's operations are geographically limited to and dependent upon the economic condition of the United States.

Additionally, if a qualitative assessment identifies impairment indicators, then the equity investments must be evaluated for impairment and written down to its fair value, if it is determined that the fair value is less than the carrying value. Any gains or losses are included within other income (expense) in the consolidated statements of operations and comprehensive income.
