Stripe has finalized a deal to acquire OpenRouter, the startup that has become a central switchboard for the AI economy, for more than $7 billion, according to Bloomberg. The report caps weeks of speculation that began when the Wall Street Journal revealed acquisition talks last month.

OpenRouter lets developers and companies compare, route and switch between hundreds of AI models from providers including OpenAI, Anthropic, Google, Meta and a long tail of open-weight startups — all through a single API. Its CEO, Alex Atallah, has described the company as 'Stripe for AI': one access point that keeps customers from being locked into any single model provider. The startup says it serves 8 million users and routes requests across more than 400 models.

The price marks a stunning leap for a company that raised a $113 million Series B in May at a reported $1.3 billion valuation, with backing from Sequoia, Andreessen Horowitz, Menlo Ventures and Alphabet's Capital G. Just three months later, Bloomberg reported the acquisition price is more than $7 billion — roughly five times that valuation.

The deal would make OpenRouter one of the most expensive AI acquisitions on record, trailing only a handful of blockbusters such as SpaceX's $60 billion purchase of Cursor. Stripe, the payments infrastructure giant, is betting that as companies spend more on AI, the plumbing that connects them to models will become as valuable as the models themselves.

For the AI industry, the acquisition raises questions about neutrality: OpenRouter built its reputation as an independent marketplace for model choice. Absorbed into Stripe — which processes the payments of millions of businesses, and which is itself in talks to buy PayPal — the gateway could one day favor models or providers in ways an independent operator might not. Stripe declined to comment on the report.
