Stripe agrees to buy AI routing startup OpenRouter for over $7 billion

Stripe has reportedly finalized an agreement to acquire AI model-routing platform OpenRouter for more than $7 billion, months after the startup was valued at $1.3 billion in its latest funding round. Summary Stripe has reportedly agreed to acquire OpenRouter for more than $7 billion. OpenRouter was valued at $1.3 billion after raising $113 million in May. The platform provides access to more than 500 AI models from over 80 providers through a single interface. Stripe has been expanding its infrastructure for AI agents and machine initiated payments. Bloomberg reported on Sunday that Stripe had reached a deal to buy OpenRouter, citing people familiar with the matter, while TechCrunch later reported the transaction and noted that Stripe had not formally announced the acquisition. A Stripe spokesperson declined to confirm the deal, telling TechCrunch that the company “does not comment on rumors or speculation.” The reported agreement therefore remains unconfirmed by Stripe or OpenRouter despite multiple reports that negotiations have concluded. OpenRouter gives developers a single interface for accessing hundreds of artificial intelligence models from providers including OpenAI, Anthropic, Google and DeepSeek. Developers can move workloads between models without rebuilding their integrations, while its system also manages billing, routing and fallback providers when services become unavailable. The model has turned OpenRouter into a fast-growing layer between AI developers and the companies supplying the underlying models. OpenRouter currently lists more than 500 models and over 80 providers under its paid plans, according to its website. CEO Alex Atallah has previously described the service as the “Stripe for AI,” comparing its single integration for multiple AI providers with Stripe’s role in simplifying access to payment infrastructure. Axios reported the comparison in July as Stripe was already discussing a possible takeover of the startup. OpenRouter acquisition follows rapid growth in AI usage OpenRouter’s reported sale price comes less than three months after a major financing round that placed a much lower value on the business. The company announced in May that it had raised $113 million in Series B funding led by CapitalG, Alphabet’s independent growth fund. NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures, AMP PBC and Pace Capital participated alongside existing investors Andreessen Horowitz and Menlo Ventures.
