OpenAI will invest $2 million in API credits into every startup in Y Combinator's current batch, in exchange for equity. Sam Altman announced the offer in an X post late Tuesday, saying he was excited to see what "tokenmaxxing" startups can build.
To clear up the obvious: these are API tokens, the things developers pay for when calling an LLM. Not crypto, not OpenAI equity. The deal is compute-for-equity, dressed up with a slightly meme-y label.
What the math probably looks like
The equity percentage wasn't in the post. The Information first reported the offer late Tuesday, and OpenAI hasn't published any official documentation around it. YC's own standard deal is $500,000 for 7%, structured as a SAFE. Whatever OpenAI takes presumably comes on top of that, out of the founders' remaining stake.
And the $2 million figure isn't $2 million in cash. It's API credits at retail prices, which cost OpenAI substantially less than face value to actually provide. The startup gets compute it would have had to pay for anyway. OpenAI gets equity at what amounts to a discounted cost basis. Whether that's a deal worth taking depends entirely on how much Codex and the API you were planning to burn through.
Why Codex, why now
Altman isn't being subtle. "Tokenmaxxing" has been kicking around AI Twitter as shorthand for organizations that lean heavily on LLM usage as a productivity input. Get YC founders building on Codex before they shop around, lock in the habit early, and you extend OpenAI's reach into a whole generation of alumni.
Anthropic has been steadily eating into OpenAI's developer market share with Claude. The enterprise fight is the one that matters. Founders coming out of YC over the next few years will pick default tools that turn into long-term contracts.
The platform risk worth thinking about
One reply to Altman's post put it bluntly: take the tokens, and there's a non-zero chance OpenAI studies exactly what you're building and ships a free version into ChatGPT. Same warning Salesforce platform devs got a decade ago. Doesn't make it wrong.
The comparison to Yuri Milner's 2011 offer to YC startups came up almost immediately in replies, and it's a generous one. Milner was an outside investor with no competing product. OpenAI is the platform every AI startup either builds on or competes with.
YC's current batch wraps in the coming months. Which founders took the deal, and which routed around it, will become visible in their tech stacks soon enough.
