Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Principal Business	Organization and Principal Business CĪON Investment Corporation, or the Company, was incorporated under the general corporation laws of the State of Maryland on August 9, 2011 and commenced operations on December 17, 2012. The Company is an externally managed, non-diversified, closed-end management investment company that has elected to be regulated as a business development company, or BDC, under the 1940 Act. The Company elected to be treated and intends to qualify annually for U.S. federal income tax purposes as a regulated investment company, or RIC, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code. The Company’s investment objective is to generate current income and, to a lesser extent, capital appreciation for investors. The Company’s portfolio is comprised primarily of investments in senior secured debt, including first lien loans, second lien loans and unitranche loans, and, to a lesser extent, collateralized securities, structured products and other similar securities, unsecured debt, and equity, of private and thinly-traded U.S. middle-market companies. The Company is managed by CION Investment Management, LLC, or CIM, an affiliate of the Company and a registered investment adviser. Pursuant to an investment advisory agreement with the Company, CIM oversees the management of the Company’s activities and is responsible for making investment decisions for the Company’s investment portfolio. On July 30, 2026, the board of directors of the Company, including a majority of the board of directors who are not interested persons, approved the renewal of the second amended and restated investment advisory agreement with CIM for a period of twelve months, commencing August 7, 2026. The Company has also entered into an administration agreement with CIM to provide the Company with administrative services necessary for it to operate. The Company and CIM previously engaged Apollo Investment Management, L.P., or AIM, a subsidiary of Apollo Global Management, Inc., or, together with its subsidiaries, Apollo, a leading global alternative investment manager, to act as the Company’s investment sub-adviser. On July 11, 2017, the members of CIM entered into a third amended and restated limited liability company agreement of CIM, or the Third Amended CIM LLC Agreement, for the purpose of creating a joint venture between AIM and CION Investment Group, LLC, or CIG, an affiliate of the Company. Under the Third Amended CIM LLC Agreement, AIM became a member of CIM and was issued a newly-created class of membership interests in CIM pursuant to which AIM, among other things, shares in the profits, losses, distributions and expenses of CIM with the other members in accordance with the terms of the Third Amended CIM LLC Agreement, which results in CIG and AIM each owning a 50% economic interest in CIM. On July 10, 2017, the Company’s independent directors unanimously approved the termination of the investment sub-advisory agreement with AIM, effective as of July 11, 2017. Although the investment sub-advisory agreement and AIM's engagement as the Company’s investment sub-adviser were terminated, AIM continues to perform certain services for CIM and the Company. AIM is not paid a separate fee in exchange for such services, but is entitled to receive distributions as a member of CIM as described above. On December 4, 2017, the members of CIM entered into a fourth amended and restated limited liability company agreement of CIM, or the Fourth Amended CIM LLC Agreement, under which AIM may perform certain services for CIM, which include, among other services, providing (a) trade and settlement support; (b) portfolio and cash reconciliation; (c) market pipeline information regarding syndicated deals, in each case, as reasonably requested by CIM; and (d) monthly valuation reports and support for all broker-quoted investments. AIM may also, from time to time, provide the Company with access to potential investment opportunities made available on Apollo's credit platform on a similar basis as other third-party market participants. All of the Company's investment decisions are the sole responsibility of, and are made at the sole discretion of, CIM's investment committee, which consists entirely of CIG senior personnel. On October 5, 2021, the Company's shares of common stock commenced trading on the New York Stock Exchange, or the NYSE, under the ticker symbol “CION”, or the Listing. As a result, on October 5, 2021, the Company and CIM entered into the second amended and restated investment advisory agreement in order to implement the changes to the advisory fees payable from the Company to CIM that became effective upon the Listing that (i) reduced the annual base management fee, (ii) amended the structure of the subordinated incentive fee on income payable by the Company to CIM and reduced the hurdle and incentive fee rates, and (iii) reduced the incentive fee on capital gains payable by the Company to CIM (as described in further detail in Notes 2 and 4). On February 26, 2023, the Company’s shares of common stock and the Company's Series A Notes listed and commenced trading in Israel on the Tel Aviv Stock Exchange Ltd., or the TASE, under the ticker symbol “CION” and “CION B1”, respectively. On August 31, 2026, the Company's Series A Notes were delisted from trading on the TASE because of the Company's repayment in full of such Series A Notes (see Note 8). On October 9, 2024, the Company’s 7.50% Notes due 2029, or the 7.50% Public 2029 Notes, listed and commenced trading on the NYSE under the ticker symbol “CICB” and on February 12, 2026, the Company’s 7.50% Notes due 2031, or the 7.50% Public 2031 Notes, listed and commenced trading on the NYSE under the ticker symbol “CICC”.
