OpenRouter more than doubles valuation to $1.3B in a year

OpenRouter, an AI gateway startup founded in 2023, raised $113 million in Series B funding led by CapitalG, the growth venture fund of Alphabet, reaching a post-money valuation of approximately $1.3 billion. The valuation more than doubles the company's estimated $547 million valuation from a year ago, driven by a surge in demand as AI work shifts to agents and enterprises seek multi-model flexibility. OpenRouter now processes 100 trillion tokens per month across over 400 models, up fivefold from six months ago, signaling a market shift away from vendor lock-in toward a multi-model future.

Popular AI gateway maker OpenRouter https://openrouter.ai/ , founded in 2023, has raised a hefty $113 million Series B led by CapitalG, the growth venture fund of Google parent company Alphabet. While the startup didn’t disclose its new valuation, The New York Times reports https://www.nytimes.com/2026/05/26/business/dealbook/openrouter-ai-models-fundraising.html that it landed at about $1.3 billion post-money. This is a hefty increase from the estimated $547 million post-money valuation it hit a year ago, per PitchBook, after raising $40 million in Series A funding https://finance.yahoo.com/news/openrouter-raises-40-million-scale-130000358.html in June 2025. That round was led by Andreessen Horowitz and Menlo Ventures, with participation from Sequoia. What a difference a year makes. Since then, AI work has shifted from training to inference to, now, agents. And OpenRouter’s AI gateway has soared in popularity in response. The gateway helps enterprises and other AI users select different models for different jobs to control costs or increase reasoning and accuracy for the task at hand. OpenRouter provides access to over 400 models, including Anthropic, Google, OpenAI, xAI, and DeepSeek, it says. It claims 8 million global users and 100 trillion tokens processed per month, or about 25 trillion per week. That’s a 5x increase from the 5 trillion tokens it was processing per week just six months ago. OpenRouter’s success means that the AI model is increasingly becoming an invisible, swappable engine for AI tasks. Rather than a future where startups or enterprises standardize on a model of choice — perhaps creating a single all-powerful model maker in the process — the growth of OpenRouter indicates something else. Companies have no plans to get locked into a model vendor as they did with their various SaaS providers. The multi-model future is already here.
