OpenAI just gave Cerebras an IPO-shaped booster shot

The AI arms race just found another cashier

OpenAI is reportedly paying Cerebras Systems more than $20 billion over three years, and suddenly the private-chip maker looks a lot less like a science project and a lot more like a future ticker. Prediction markets are now pricing Cerebras as the second most likely IPO this year, which is the kind of glow-up that makes bankers reach for the champagne and regulators reach for the file cabinet.

Why investors are squinting at the fine print

The weirdest part? OpenAI is reportedly structuring part of the arrangement as a "working capital deposit" instead of a normal purchase contract. In plain English: some of the money may show up more like an asset than a pure expense, which is a very Wall Street way of making a giant compute bill look slightly less like a giant compute bill.

That matters because OpenAI is reportedly staring down:

• $45 billion of compute spend this year
• $90 billion next year
• more than $650 billion over five years

If you’re trying to pitch a future IPO, that’s not exactly a diet plan.

Nvidia and AMD are still in the group chat

Cerebras isn’t the only chip relationship OpenAI is juggling. Nvidia still anchors a huge chunk of the compute stack, and AMD has already been pulled into OpenAI’s orbit through earlier chip and equity deals. So while the headline is really about Cerebras, the subtext is that OpenAI is diversifying its suppliers like a nervous shopper splitting groceries between three different stores.

The comeback story gets a plot twist

Cerebras already tried to go public in 2024, then hit a national-security snag tied to its UAE business and later withdrew its filing in 2025. This new OpenAI deal could clean up the customer-concentration problem and put an IPO back on the table — possibly at a valuation around $35 billion, if the latest reports are right.

Big picture: the AI boom is no longer just about who has the best chips. It’s about who can finance the most electricity-hungry, balance-sheet-bending compute binge without making public-market investors flinch.
