Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND OPERATIONS OF THE FUND	ORGANIZATION AND OPERATIONS OF THE FUND Venture Lending & Leasing IX, Inc. (the “Fund”) was incorporated in Maryland on June 28, 2017 as a non-diversified, closed-end management investment company that elected to be treated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”) and is managed by Westech Investment Advisors LLC (the “Manager” or “Management”) whose ultimate parent is P10, Inc., a Delaware corporation. The Fund will be dissolved on December 31, 2028 unless the Board of Directors (the “Board”) opts to elect early dissolution. One hundred percent of the stock of the Fund is held by Venture Lending & Leasing IX, LLC (the “Company”). Prior to commencing operations on May 2, 2018, the Fund had no operations other than accruing organizational expenses and the sale to the Company of 100,000 shares of common stock, $0.001 par value for $25,000 in June 2017. This issuance of stock was a requirement to apply for a finance lender’s license from the California Commissioner of Corporations, which was obtained on September 22, 2017. The Fund’s investment objective is to achieve superior risk-adjusted investment returns and it seeks to achieve that objective by providing debt financing to portfolio companies, most of which are private. The Fund generally receives warrants to acquire equity securities in connection with its portfolio investments and generally distributes these warrants to its shareholder upon receipt, or soon thereafter. The Fund also has guidelines for the percentages of total assets that are invested in different types of assets. The portfolio investments of the Fund primarily consist of debt financing to early and expansion stage venture capital-backed technology companies. In the Manager’s opinion, the accompanying condensed interim financial statements (hereafter referred to as “financial statements”) include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of financial position and results of operations for interim periods. Certain information and note disclosures normally included in audited annual financial statements prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) have been omitted; however, the Fund believes that the disclosures made are adequate to make the information presented not misleading. The interim results for the three months ended March 31, 2025 are not necessarily indicative of what the results would be for a full year. These financial statements should be read in conjunction with the financial statements and the notes included in the Fund’s Annual Report on Form 10-K for the year ended December 31, 2024.
