OpenRouter more than doubles valuation to $1.3B in a year
Summary
OpenRouter is an AI gateway that routes users to many model providers and has grown fast as inference and agent workloads expand. The article gives business traction data, not a new research method.
Problem
- Teams building AI products need to choose models per task while controlling cost, reasoning quality, and accuracy.
- Vendor lock-in matters because inference and agent workloads may need different models, price points, and capabilities over time.
Approach
- OpenRouter provides a gateway API with access to more than 400 models.
- The gateway lets users select different models for different jobs, including models from Anthropic, Google, OpenAI, xAI, and DeepSeek.
- The core mechanism is simple: OpenRouter sits between the application and model providers, so the application can route requests without integrating each provider separately.
- This makes the model a swappable execution engine for AI tasks.
Results
- OpenRouter raised a $113 million Series B led by CapitalG.
- The New York Times reports a post-money valuation of about $1.3 billion.
- PitchBook estimated OpenRouter at $547 million post-money after its June 2025 $40 million Series A, so the reported valuation more than doubled in about a year.
- OpenRouter claims 8 million global users.
- OpenRouter says it processes 100 trillion tokens per month, or about 25 trillion tokens per week.
- Weekly token volume rose 5x in six months, from 5 trillion tokens per week to about 25 trillion tokens per week.
