Stripe has agreed to acquire OpenRouter, an AI model gateway and routing platform that helps businesses and developers access multiple artificial intelligence models through a single interface.
Stripe officially announced the agreement on August 19, marking a major expansion of the payments company’s growing role in AI infrastructure.
OpenRouter allows users to route AI workloads across more than 400 models from over 80 providers. The platform is designed to help businesses choose models based on factors such as performance, availability and cost, while giving developers a unified way to manage AI model usage.
Stripe has not publicly disclosed the financial terms of the acquisition. However, multiple reports have placed the value of the deal above $7 billion, with Reuters reporting that sources estimate it at just over $8 billion. Axios has separately reported that the transaction is worth more than $8 billion in cash and stock.
The acquisition is significant because OpenRouter has grown rapidly in a relatively short period. The company was founded in 2023 and had raised $113 million in a Series B funding round announced in May at a reported valuation of about $1.3 billion. Its investors include Andreessen Horowitz, Menlo Ventures, Sequoia Capital and CapitalG.
OpenRouter has positioned itself as an important layer between AI applications and model providers. Instead of building separate integrations for different AI systems, developers can use OpenRouter as a common gateway and switch between models depending on their requirements.
For Stripe, the acquisition fits into a broader strategy focused on building financial and commercial infrastructure around artificial intelligence. Stripe has been developing tools for businesses that need to track AI usage, manage token-based pricing and handle payments as AI services become increasingly integrated into software products.
The two companies already had a relationship before the acquisition. Stripe had worked with OpenRouter on billing and usage management, giving Stripe experience with the economics of businesses that consume AI models at scale. The acquisition could allow Stripe to combine that experience with OpenRouter’s model-routing technology.
AI models are increasingly being offered by multiple competing providers, creating a complicated environment for companies that need to balance performance, availability and cost. OpenRouter’s role is to simplify that process by providing a single gateway through which businesses can access different models.
The deal also highlights how quickly the value of AI infrastructure companies is rising. OpenRouter’s reported valuation of around $1.3 billion in May was followed only months later by acquisition reports valuing the company at more than $7 billion, and later estimates above $8 billion.
The acquisition is expected to strengthen Stripe’s position as businesses increasingly use AI agents and model-based services that generate large volumes of usage and transactions. Stripe says OpenRouter will help businesses optimize token routing and usage as AI becomes more deeply integrated into commercial applications.
