Stripe finalizes its OpenRouter agreement for an estimated $7.5 billion or higher.

      Stripe has reached an agreement to acquire OpenRouter, a startup that provides software to help businesses manage their expenditures across numerous AI models. The payment company confirmed the acquisition on Wednesday, officially announcing a deal that had been reported by the media earlier this month.

      Neither company disclosed a specific price for the transaction. Reports from different sources vary, with The New York Times stating that Stripe is paying $7.5 billion based on information from an insider. This includes $1.5 billion for OpenRouter's founders and $6 billion for its investors. In contrast, Axios reported a higher figure, exceeding $8 billion, most of which is in stock.

      Regardless of the exact amount, it represents a significant increase. Investors had valued OpenRouter at around $1.3 billion in a funding round this year, according to Bloomberg. Their investors include notable firms such as Andreessen Horowitz, Sequoia Capital, Nvidia, and CapitalG, one of Alphabet's venture arms. If The New York Times' estimate is accurate, these investors are exiting at multiple times that valuation, and this is just months later.

      What OpenRouter does

      OpenRouter acts as a unified access point to the AI market. Through one interface, developers can connect to over 400 models from more than 80 providers, allowing them to compare options and direct requests to the most suitable model based on cost, speed, and reliability. The company claims to process more than 10 trillion tokens daily and serves over 10 million developers and businesses.

      This extensive reach is central to OpenRouter's business model. Established in 2023 with only a few models, its token volume has significantly increased, doubling approximately every few months, according to its supporters. Prominent new models often debut on this platform, and AI researcher Andrej Karpathy has referred to it as the “transfer switch” of AI, highlighting its role in managing data flow between systems.

      Tokens represent the billing unit for AI models and are akin to fragments of words. As companies increasingly utilize AI, their token expenditures have surged. Efficient routing has become a strategy to control costs, with the concept being to allocate simpler tasks to less expensive, often open-source models and reserve the more costly advanced models for complex tasks. OpenRouter also provides customers with the option to switch to a backup model if a provider fails.

      This routing approach has gained appeal due to the emergence of powerful open-source models, many of which originate from China. The Times cited Kimi, from the startup Moonshot AI, as an example. Such models are driving firms to consider switching models depending on the task at hand.

      Why Stripe wanted it

      Stripe already acts as an intermediary between businesses and their finances, optimizing payments, authorizations, and fraud protection. It has positioned OpenRouter as a similar solution for AI expenditures. CEO Patrick Collison remarked that tokens are "the central currency for companies building with AI." Together, the two companies aim to facilitate "efficient token spending," he stated.

      This acquisition is part of Stripe's effort to expand into the AI sector, which includes a Token Billing product introduced last year. OpenRouter's founder, Alex Atallah, emphasized the importance of a “multi-model” approach, noting that no single model is optimal for every task. Developers, he pointed out, require a neutral platform to manage various models. Atallah is also known for co-founding the NFT marketplace OpenSea.

      Neutrality is a key aspect of OpenRouter's value proposition and a critical point of consideration surrounding the acquisition. The company insists that its routing decisions prioritize users rather than favoring any specific model or provider, a principle it claims will remain unchanged under Stripe’s ownership. Stripe, in turn, has mentioned that well-known firms like Nvidia, Zoom, and the coding startup Lovable already utilize OpenRouter.

      OpenRouter stated it would continue to function as it does now, retaining its name, product, and roadmap. The company, which launched in 2023, has experienced rapid growth since its inception. However, the deal must still meet the usual closing conditions and is expected to finalize in the upcoming weeks.

      Stripe’s broader strategy

      Stripe ranks among the largest private technology firms and has avoided public market listings, with the founders expressing a preference to remain private. They believe this approach is beneficial at a crucial juncture, as mentioned to investors. In a recent letter to investors, viewed by Axios, the company referred to the year's start as "the beginning of the singularity," marking a significant turning point. The company reported a 41 percent increase in first-half revenue compared to the previous year. Notably, 88 percent of the Forbes AI 50, including OpenAI and Anthropic, rely on its platform.

      An employee share sale in February valued Stripe at $159 billion, an increase from $91.5 billion the prior year, according to Axios. Additionally, the company is pursuing a much larger acquisition target, a bid for PayPal in collaboration with the investment firm Advent
