Investors pushed back on Nvidia's single customer risk, halving the chipmaker's Ohio campus backstop to under $120B. In the same week, Stripe reportedly agreed to acquire AI model routing startup OpenRouter for more than $7 billion.
Nvidia has trimmed its planned guarantee for the first phase of OpenAI's Ohio data-center campus from roughly $250 billion to less than $120 billion, per the TLDR AI daily digest.
The deal is still closing, the five-gigawatt campus is still being built, and Nvidia is still on the hook. The change is the size of the backstop, not the existence of it. The named reason is investor concern about the chipmaker's single-customer risk exposure: OpenAI's capex appetite is concentrated enough that one financing partner's exposure cap is now on the public record.
OpenAI will decide later how to finance the remaining buildout cost, leaving who absorbs the gap open.
A parallel signal landed the same week. Stripe has reportedly agreed to acquire OpenRouter, an AI model-routing service that lets developers pick which model handles each request. The reported price is more than $7 billion, a step up from OpenRouter's reported $1.3 billion valuation after its May 2026 funding round. Neither company has confirmed the deal. The pattern is the same: a payments incumbent buying into the routing layer at a price the market priced as scarce six months ago.
