Accounting Policies [Abstract]
Significant Accounting Policies	Note 2 — Significant Accounting Policies *Basis of Presentation* The accompanying financial statement is presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). *Liquidity and Capital Resources* The Company’s liquidity needs up to December 31, 2025 had been satisfied through the loan under an unsecured promissory note from the Sponsor of up to $400,000 (see Note 5). As of December 31, 2025, the Company had no cash and a working capital deficit of $280,425. In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (the “Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans. In the event that a Business Combination does not close, the Company may use amounts held outside the Trust Account to repay the Working Capital Loans but no proceeds from the Trust Account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into Private Warrants of the post Business Combination entity at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Warrants. As of December 31, 2025, no such Working Capital Loans were outstanding. In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Presentation of Financial Statements – Going Concern,” the Company completed its Initial Public Offering on January 22, 2026 and the sale of additional Units as a result of the partial exercise by the underwriters of their over-allotment option on January 26, 2026, at which time the capital in excess of the funds deposited in Trust Account and/or used to fund offering costs and other expenses was released to the Company for general capital purposes. The Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination. The Company has until the Completion Window to complete the initial Business Combination. Management has determined that upon the consummation of the Initial Public Offering, the sale of the Private Warrants, the sale of additional Units, and the sale of additional Private Warrants as a result of the partial exercise by the underwriters of their over-allotment option, the Company has sufficient funds to finance the working capital needs of the Company within one year from the date of issuance of the financial statements. *Emerging Growth Company Status* The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. X3 ACQUISITION CORP. LTD. NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 *Use of Estimates* The preparation of financial statements in conformity with US GAAP requires management to 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 and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. *Cash and Cash Equivalents* The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash or cash equivalents as of December 31, 2025. *Concentration of Credit Risk* Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows. *Deferred Offering Costs* The Company complies with the requirements of the FASB ASC Topic 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Deferred offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC Topic 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the warrants and then to the Class A ordinary shares. On January 22, 2026, upon completion of the Initial Public Offering, offering costs allocated to the public shares subject to possible redemption were charged to temporary equity and offering costs allocated to the Public Warrants and Private Warrants were charged to shareholders’ deficit as Public Warrants and Private Warrants, after management’s evaluation, are accounted for under equity treatment. *Fair Value of Financial Instruments* The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet, primarily due to their short-term nature. *Net Loss per Ordinary Share* Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the period, excluding ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 750,000 ordinary shares that would have been subject to forfeiture had the over-allotment option not been exercised by the underwriters. On January 23, 2026, the underwriters partially exercised their over-allotment option and the sale of Units pursuant thereto was consummated on January 26, 2026 resulting in 625,000 founder shares no longer subject to forfeiture. As of December 31, 2025, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the period presented. *Income Taxes* The Company accounts for income taxes under FASB ASC Topic 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. X3 ACQUISITION CORP. LTD. NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2025, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. *Derivative Financial Instruments* The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with FASB ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. The underwriters’ over-allotment option is deemed to be a freestanding financial instrument indexed on the contingently redeemable shares and are be accounted for as a liability pursuant to FASB ASC Topic 480 since the underwriters’ over-allotment was not fully exercised at the time of the Initial Public Offering. As of December 31, 2025, there is no over-allotment option liability recognized in the Company’s balance sheet. On January 22, 2026, the Company recognized a total of $251,400 of over-allotment option liability. On January 26, 2026, the Company reduced the over-allotment option liability by $209,500 as a result of the partial exercise by the underwriters of their over-allotment option. The remaining underwriters’ over-allotment option expired on March 6, 2026, and the Company closed the remaining $41,900 over-allotment option liability against accumulated deficit. *Warrant Instruments* The Company accounts for the Public Warrants and Private Warrants issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values. There were no Public Warrants or Private Warrants outstanding as of December 31, 2025. *Share-Based Compensation* The Company records share-based compensation in accordance with FASB ASC Topic 718, “Compensation-Share Compensation”, guidance to account for its share-based compensation. It applies a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments are valued by multiplying the marketable value per founder share (defined in Note 5) by the probability of successful closing of an initial Business Combination. Grants of share-based payment awards issued to non-employees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. *Recent Accounting Pronouncements* Management does not believe that any recently issued, but not effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.
