On December 9, 2024, the OpenAI Startup Fund disclosed that it had raised $44,281,693 for its fifth special purpose vehicle (SPV), its largest such vehicle at the time. The money was raised for the separately managed Startup Fund—not by OpenAI, the operating company—and the fund did not identify which specific startups would receive it. The five SPVs disclosed during 2024 raised about $114.2 million combined.
What the $44.28 million was—and was not
The reported amount was for SPV V, a dedicated investment vehicle associated with the OpenAI Startup Fund. It was not a new general-purpose fund raised by OpenAI itself, nor evidence that OpenAI put $44.28 million of corporate money into startups. The Startup Fund says OpenAI is not one of its investors; it identifies Microsoft and other OpenAI partners as investors.
The fund is affiliated with OpenAI and uses its name, but that affiliation should not be confused with corporate ownership or financing. The public reporting does not give a complete, investor-by-investor list for SPV V, so Microsoft’s participation in the Startup Fund does not establish that it funded this particular vehicle or supplied the full amount.
What an SPV does
A special purpose vehicle is a separate legal entity formed to pool capital for a defined investment purpose. In venture investing, it can let investors participate in a particular opportunity or a focused group of investments outside a main fund. A manager might use one for follow-on investments in existing portfolio companies, new deals, or a concentrated opportunity that arises after the main fund is established.
#1 Best Overall
An SPV does not necessarily correspond to one startup. In this case, the fund said SPV V would support a variety of existing portfolio companies and make new investments. It did not publicly name the recipients or say how much would go to follow-ons versus new deals. The structure offers flexibility, but makes it harder for outsiders to see how capital and exposure are distributed across the fund’s vehicles.
Five SPVs disclosed during 2024
SPV V was the fifth disclosed vehicle in a sequence of fundraising disclosures during 2024. Together, the five amounts total $114,198,051, or about $114.2 million.
| Vehicle | Disclosed amount | Reported timing |
|---|---|---|
| SPV I | $10,000,000 | January 2024 |
| SPV II | $24,999,947 | April 2024 |
| SPV III | $5,000,000 | May 2024 |
| SPV IV | $29,916,411 | July 2024 |
| SPV V | $44,281,693 | December 2024 |
| Total | $114,198,051 | 2024 |
The amounts and chronology were reported by TechCrunch. The fifth vehicle was larger than each of the four preceding 2024 SPVs, which is why it was described as the fund’s largest SPV yet—not its largest fund overall.
How that compares with the original fund
The Startup Fund’s original vehicle, OpenAI Startup Fund I, L.P., reported a $175.25 million offering in an SEC Form D amendment. The filing lists $175.25 million as both the total offering amount and total amount sold, and reports 14 investors. It identifies the issuer as a Delaware limited partnership and the securities as pooled investment fund interests. The first sale date shown is October 29, 2021; the amendment reporting the offering as sold is dated May 24, 2023. See the SEC filing.
These figures describe different vehicles and disclosures. The original fund’s reported offering and the later SPV raises should not simply be added and presented as one total of money available to invest, assets under management, or capital deployed. A fundraising disclosure does not by itself show when capital was called, how much was invested, or whether amounts across related vehicles overlap economically. The SEC also cautions that it has not reviewed the Form D or determined whether its information is accurate or complete; it is a filing disclosure, not an audited fund report.
Who manages the fund?
The fund was initially structured with Sam Altman as its named controller. In April 2024, formal control was transferred to general partner Ian Hathaway, according to TechCrunch’s reporting. That report said Altman had no personal investment or financial interest in the fund. The change matters because a fund associated with the CEO of OpenAI could prompt questions about control and conflicts, even though the fund says OpenAI itself is not an investor.

What companies and sectors are associated with the fund?
The Startup Fund describes an early-stage focus that includes healthcare, law, education, energy and infrastructure, and the sciences. The December 2024 report highlighted portfolio activity involving Harvey, Mem, Thrive Health, Unify, and Anysphere, the company behind Cursor. These are examples of the fund’s broader activity—not confirmed recipients of SPV V capital. The public description of SPV V does not connect it to any named company.

Why repeated SPV fundraising matters
Five disclosed SPVs in one year show continued capital formation around the Startup Fund’s investment activity. One reasonable interpretation is that separate vehicles let the fund raise targeted capital as follow-on needs or new opportunities arise, rather than relying only on the original pooled fund. The pace may also reflect investor interest in gaining exposure to companies connected to the AI ecosystem. Those are interpretations, not proof of investor confidence, a changed investment strategy, or successful returns.
Best Value
The model has trade-offs. A focused vehicle can make it easier to allocate capital to particular opportunities, but it can also create more concentrated exposure than a broad fund. Repeated vehicles may make the overall picture less transparent: public reporting on SPV V did not disclose the complete investor roster, fees, carried interest, governance terms, investment allocations, capital-call status, deployment, or performance. A larger raise is not evidence that the money has already been invested or that the investments have appreciated.
Quick Recap
What the disclosure does not establish
- Which specific companies received, or will receive, SPV V capital.
- Whether the $44.28 million was primarily for follow-on rounds, new investments, or a mix.
- The full list of SPV V investors or the amount any one investor contributed.
- The vehicle’s fees, carried interest, governance rights, or investor-level terms.
- Whether all the reported capital had been called or deployed, or how the vehicle performed.
