Stripe buys AI gateway OpenRouter for $7.5B — and it's not really about the 'singularity'
Payments company Stripe has confirmed acquiring OpenRouter for a reported $7.5 billion, far above the startup's $1.3 billion valuation from May. Despite founders jokingly citing the 'singularity,' the deal appears aimed at expanding Stripe into AI expense management.
Stripe confirmed on Wednesday that it is acquiring OpenRouter, a startup that routes prompts between different AI models. While the deal price wasn't officially disclosed, sources told the New York Times it totaled about $7.5 billion — a steep jump from OpenRouter's $1.3 billion valuation just three months earlier, in May. Reportedly, OpenRouter's founders alone will pocket $1.5 billion from the sale, while investors will split the remaining $6 billion. Stripe is said to have outbid other suitors, including Databricks.
In a letter to investors, published by Eric Newcomer and verified by TechCrunch, Stripe founders Patrick and John Collison jokingly attributed the deal to the 'singularity' — the hypothetical point where humans and technology merge into a new species. Patrick Collison had already used the term with tongue in cheek at the company's own conference in April.
The real reasons
More seriously, the founders pointed to how AI is fueling Stripe's business growth, as more AI-driven companies launch and adopt its payment tools. Stripe says 88% of the Forbes AI 50 companies, including OpenAI and Anthropic, use its products, as do 100% of Brex's fastest-growing startups.
The founders also noted significant overlap between Stripe's and OpenRouter's customer bases, since OpenRouter is widely used by developers and Stripe is one of the largest developer platforms globally. OpenRouter is expected to keep operating independently once the deal closes in a few weeks, with its product, mission and existing commitments unchanged, according to its own blog post.
Analysts see a broader strategic shift. Most of Stripe's past major acquisitions focused on helping businesses collect incoming payments, but buying OpenRouter pushes the company into expense management, starting with AI spending. PitchBook analyst Franco Granda described it as Stripe's deliberate move to embed itself in AI-era capital flows, giving it visibility into developer AI usage and leverage over AI suppliers. Similar AI expense-management tools are already being built by Databricks, Rippling and Ramp.
