Stripe has agreed to acquire AI model marketplace OpenRouter for more than $7 billion, according to a Bloomberg report, in a deal that would give the payments company a much larger position in the growing AI infrastructure market.
The agreement has reportedly been finalised, although the final purchase price could still change. Neither Stripe nor OpenRouter had publicly announced the acquisition at the time of reporting.
The reported deal comes only months after OpenRouter raised $113 million in a Series B funding round that valued the company at about $1.3 billion.
OpenRouter provides developers and businesses with a single interface for accessing hundreds of AI models from different companies. Instead of building separate connections to providers such as OpenAI, Anthropic, Google and other model developers, users can access and switch between models through OpenRouter.
The platform has become increasingly popular as businesses use more than one AI model for different tasks.
Why OpenRouter has become valuable
AI companies have traditionally competed to build the best model. But as more models become available, businesses also need a way to compare them and choose the right one for each task.
OpenRouter sits between AI users and model providers.Its platform can route requests to different models based on factors such as cost, performance, availability and reliability. This allows developers to switch models without rebuilding their applications around a new provider.
OpenRouter said in May that it was serving more than 8 million developers across more than 400 models. The company also said its weekly volume had grown from 5 trillion tokens to 25 trillion tokens in six months.
The company has since grown further. Its website currently says it serves more than 10 million global users and provides access to more than 400 models from 70 providers.
That growth has made OpenRouter an important part of the infrastructure connecting businesses and developers to AI models.OpenRouter’s reported acquisition price stands out because of how quickly the company’s valuation has increased.
In May, OpenRouter raised $113 million in Series B funding led by CapitalG, Alphabet’s independent growth fund. The round included investments from NVIDIA’s NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures and Databricks Ventures, alongside existing investors Andreessen Horowitz and Menlo Ventures.
The funding round valued OpenRouter at about $1.3 billion, according to TechCrunch.A purchase price above $7 billion would therefore represent a major increase from that valuation within only a few months.
The rapid increase reflects the growing importance of infrastructure that helps businesses manage multiple AI models rather than relying on a single provider.
Why Stripe is interested
Stripe is best known for its payment processing infrastructure, but the company has been expanding into other parts of the technology stack.
The company has been building products around AI-powered commerce and payments, including infrastructure designed to allow businesses to accept payments through AI platforms and enable AI agents to make transactions.
OpenRouter could give Stripe another important piece of AI infrastructure.
By owning a platform that connects users to hundreds of AI models, Stripe would gain a direct position in the layer between AI applications and model providers.
That could also create opportunities to connect AI usage with billing and payments, particularly as businesses increasingly pay for AI services based on usage.
The acquisition would therefore take Stripe further beyond traditional payment processing and deeper into the infrastructure supporting AI applications.
OpenRouter’s main appeal has been its ability to give developers access to different AI models without locking them into one provider.
The reported acquisition raises questions about whether that model will remain unchanged under Stripe.
For developers, the biggest concern will likely be whether OpenRouter continues to operate as a neutral gateway where users can freely compare and switch between competing AI models.
Stripe has not announced how it plans to operate OpenRouter following the reported acquisition, so it is too early to say whether pricing, model access or the platform’s policies will change.
For now, the deal remains a reported agreement rather than a publicly announced transaction.If completed, it would nevertheless represent one of Stripe’s biggest bets on AI and one of the largest acquisitions of an AI infrastructure company this year.
