Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	A. Adoption of New Accounting Standards In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740). The amendments in this ASU address investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The Company's adoption of the provisions of ASU 2023-09, effective January 1, 2025, did not have an effect on the Company’s consolidated financial statements. In March 2024, the FASB issued ASU 2024-01, Compensation—Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards. The ASU provides an illustrative example intended to demonstrate how entities that account for profits interest and similar awards would determine whether a profits interest award should be accounted for as share-based payment arrangements in accordance with FASB Accounting Standards Codification (FASB ASC) 718, Compensation-Stock Compensation. The Company's adoption of the provisions of ASU 2024-01, effective January 1, 2025, did not have an effect on the Company’s consolidated financial statements. In March 2024, the FASB issued ASU 2024-02, Codification Improvements — Amendments to Remove References to the Concepts Statements. The ASU amends the Codification to remove references to various concepts statements. In most instances, the references are extraneous and not required to understand or apply the guidance. In other instances, the references were used in prior Statements to provide guidance in certain topical areas. The Company's adoption of the provisions of ASU 2024-02, effective January 1, 2025, did not have an effect on the Company’s consolidated financial statements. In March 2025, the FASB issued ASU 2025-02, Liabilities (405): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 122, which amends an SEC paragraph noted in the Codification pursuant to the issuance of SEC Staff Accounting Bulletin No. 122, which removes the text of SAB Topic 5 FF, Accounting for Obligations to Safeguard Crypto-Assets an Entity Holds for its Platform Users. The ASU was effective immediately. The Company's adoption of the provisions of ASU 2024-02, effective January 1, 2025, did not have an effect on the Company’s consolidated financial statements. In November 2024, the FASB issued ASU 2024-04, Debt— Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion or extinguishment of convertible debt. The Company's adoption of the provisions of ASU 2024-04, effective January 1, 2026, did not have an effect on the Company’s consolidated financial statements. In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The amendments provide all entities with a practical expedient to assume that current conditions as of the balance sheet date do not change for the remaining life of the assets when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. The Company's adoption of the provisions of ASU 2025-05, effective January 1, 2026, did not have an effect on the Company’s consolidated financial statements. B. Recent Accounting Developments In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statements. The ASU is effective for all entities for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, which was clarified in ASU 2025-01. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements. In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity. The ASU revises current guidance for determining the accounting acquirer for a transaction effected primarily by exchanging equity interests in which the legal acquiree is a variable interest entity that meets the definition of a business. The amendments require an entity to consider the same factors that are currently required for determining which entity is the accounting acquirer in other acquisition transactions. The ASU is effective for annual reporting periods beginning after December 15, 2026 and interim reporting within those annual reporting periods. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been issued (or made available for issuance). The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements. In May 2025, the FASB issued ASU 2025-04, Compensation— Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer. The amendments in this ASU affect the timing of revenue recognition for entities that offer to pay share-based consideration (e.g., equity instruments) to a customer (or to other parties that purchase the entity’s goods or services from the customer) to incentivize the customer (or its customers) to purchase its goods and services. Specifically, the amendments clarify the requirements for share-based consideration payable to a customer that vest upon the customer purchasing a specified volume or monetary amount of goods and services from the entity. The ASU is effective for annual reporting periods beginning after December 15, 2026 and interim reporting within those annual reporting periods. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been issued (or made available for issuance). The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this ASU require that an entity capitalize software costs when both management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the "probable-to-complete recognition threshold"). In evaluating the probable-to complete recognition threshold, an entity is required to consider whether there is significant uncertainty associated with the development activities of the software. The ASU is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements. In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract. The ASU clarifies derivative scope exceptions for certain contracts with underlings that are based on the operations or activities of one of the parties to the contract. The ASU also clarifies the applicability of ASC Topic 606, Revenue from Contracts with Customers, and its interaction with other ASC Topics (including ASC Topic 815 on derivatives and hedging and ASC Topic 321 on equity securities), in the accounting for share-based noncash consideration (such as warrants or shares) received from a customer for the transfer of goods or services. The ASU is effective for annual periods beginning after December 15, 2026 and interim periods within those periods. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) Narrow- Scope Improvements. The amendments in this ASU do not change the fundamental nature of interim reporting or expand or reduce current interim disclosure. The amendments in this ASU clarify the guidance in ASC Topic 270 by providing a comprehensive list of required interim disclosures and codifying a disclosure principle that requires the Company to disclose events and changes that occur after the end of the most recent annual reporting period that have a material impact on its consolidated financial statements. The amendments in this ASU are effective for interim periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements. In December 2025, the FASB issued ASU 2025-12, Codification Improvements (Topic 815) The amendments in this ASU update the FASB Accounting Standards Codification for a broad range of Topics arising from technical corrections, unintended application of the Codification, clarifications, and other minor improvements. The amendments in this ASU are effective for all entities for annual periods beginning after December 15, 2026, and interim periods within those annual periods. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements.
Fair Value of Financial Instruments, Policy [Policy Text Block]	C. Fair Value of Financial Instruments The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments. These determinations were based on available market information and appropriate valuation methodologies. Considerable judgment is required to interpret market data to develop the estimates and, therefore, these estimates may not necessarily be indicative of the amount the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Refer to note 8 for a discussion of the valuation hierarchy with respect to investments-trading; other investments, at fair value; other investments sold, not yet purchased; and derivatives held by the Company. Cash and Cash equivalents: Cash and cash equivalents are carried at historical cost, which is assumed to approximate fair value. The estimated fair value measurement of cash and cash equivalents is classified within level 1 of the valuation hierarchy. Investments-trading: These amounts are carried at fair value. The fair value is based on quoted market prices of an active exchange, independent broker market quotations, market price quotations from third- party pricing services, or valuation models when quotations are not available. Other investments, at fair value: These amounts are carried at fair value. The fair value is based on quoted market prices of an active exchange, independent broker market quotations, or valuation models when quotations are not available. In the case of investments in alternative investment funds, fair value is generally based on the reported net asset value of the underlying fund. Receivables under resale agreements: Receivables under resale agreements are carried at their contracted resale price, have short-term maturities, and are repriced frequently or bear market interest rates and, accordingly, these contracts are at amounts that approximate fair value. The estimated fair value measurements of receivables under resale agreements are based on observations of actual market activity and are generally classified within level 2 of the valuation hierarchy. Trading securities sold, not yet purchased: These amounts are carried at fair value. The fair value is based on quoted market prices of an active exchange, independent market quotations, market price quotations from third party pricing services, or valuation models when quotations are not available. Other investments sold, not yet purchased: These amounts are carried at fair value. The fair value is based on quoted market prices of an active exchange, independent broker market quotations, or valuation models when quotations are not available. Securities sold under agreements to repurchase: The liabilities for securities sold under agreements to repurchase are carried at their contracted repurchase price, have short-term maturities, and are repriced frequently with amounts normally due in one month or less, accordingly, these contracts are carried at amounts that approximate fair value. The estimated fair value measurements of securities sold under agreements to repurchase are based on observations of actual market activity and are generally classified within level 2 of the valuation hierarchy. Debt: These amounts are carried at outstanding principal less unamortized discount and deferred financing costs (if applicable). However, a substantial portion of the Company's debt was assumed in the AFN Merger and recorded at fair value as of that date. As of March 31, 2026 and December 31, 2025, the fair value of the Company’s debt was estimated to be $36,383 and $42,369, respectively. The estimated fair value measurements of the debt are generally based on discounted cash flow models prepared by the Company’s management primarily using discount rates for similar instruments issued to companies with similar credit risks to the Company and are generally classified within level 3 of the valuation hierarchy. Derivatives: These amounts are carried at fair value. Derivatives may be included as a component of investments-trading; trading securities sold, not yet purchased; other investments, at fair value; and other investments, sold not yet purchased. The fair value is generally based on quoted market prices on an exchange that is deemed to be active for derivative instruments such as foreign currency forward contracts and Eurodollar futures. For derivative instruments, such as TBAs and other extended settlement trades, the fair value is generally based on market price quotations from third party pricing services.
