Payment service provider Stripe has finalized an agreement to acquire the AI model aggregation platform OpenRouter for over $7 billion. The deal was completed on August 16th local time, and the final price may still be subject to change. OpenRouter provides developers with a unified API entry point to access hundreds of open-source and proprietary AI large language models globally, offering a one-stop service for model routing, usage tracking, and billing settlement.
In May this year, OpenRouter just completed a $113 million Series B round led by CapitalG, a venture capital firm under Alphabet. The post-money valuation was approximately $1.3 billion, with investors including Sequoia Capital, Andreessen Horowitz, and Menlo Ventures. The acquisition price is more than five times the valuation at that time.
OpenRouter's CEO Alex Atallah positioned the company as "Stripe for AI," emphasizing its core value of avoiding vendor lock-in. The platform has now served over 8 million developers worldwide and provides access to more than 400 models.
This acquisition is seen as a key expansion of Stripe into the AI infrastructure field. OpenRouter generates revenue through a 5.5% platform service fee, and its billing system was originally deeply integrated with Stripe's payment tools. After the transaction, Stripe is expected to integrate its financial infrastructure with the AI model calling measurement process, securing a strategic position in the "transaction layer" within the multi-model industry landscape.
