- OpenAI is dedicating approximately $400M to its second startup fund targeting early-stage AI companies, per an SEC filing reported by the Wall Street Journal
- OpenAI's first fund raised $175M in 2021 from outside investors, with Microsoft among the named backers
- The ~$400M second fund is more than 2x the $175M the first fund attracted from external investors four years earlier
- Unlike the 2021 fund, which sourced capital from outside investors, this second fund is being funded by OpenAI itself per the SEC filing language
Why it matters: OpenAI has shifted from being a capital recipient — its first fund was seeded by outsiders including Microsoft — to deploying its own balance sheet at more than double the prior scale. With a ~$400M war chest dedicated to early-stage AI startups, OpenAI is now actively shaping the competitive landscape it competes within, not just absorbing outside investment.
