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

In a testament to the rapidly evolving landscape of artificial intelligence, OpenRouter, a popular AI gateway maker founded in 2023, has secured a substantial $113 million in Series B funding. The investment, led by CapitalG, the growth venture fund of Google parent company Alphabet, catapults the company's valuation to approximately $1.3 billion post-money, as reported by The New York Times. This remarkable surge in valuation represents a more than twofold increase from the estimated $547 million post-money valuation OpenRouter achieved a year ago.

That milestone was reached following a $40 million Series A funding round in June 2025, led by Andreessen Horowitz and Menlo Ventures, with participation from Sequoia. The AI gateway provided by OpenRouter has become increasingly popular as the industry's focus shifts from training to inference and now, agents. The platform enables enterprises and other AI users to select different models for various tasks, allowing for cost control and improved reasoning and accuracy.

OpenRouter offers access to over 400 models from prominent providers such as Anthropic, Google, OpenAI, xAI, and DeepSeek. The company's impressive growth is underscored by its user base of 8 million global users and a staggering 100 trillion tokens processed per month, which translates to approximately 25 trillion tokens per week. This represents a fivefold increase from the 5 trillion tokens processed per week just six months ago.

The success of OpenRouter suggests that the AI model is increasingly becoming an invisible, swappable engine for AI tasks. Rather than standardizing on a single model, companies are opting for a multi-model approach, indicating a desire to avoid vendor lock-in. As the AI landscape continues to evolve, OpenRouter's growth signals a future where flexibility and interoperability will be key.
