OpenRouter Raises $113M Series B Led by Alphabet's CapitalG at a $1.3B Valuation — Weekly Token Volume Jumps from 5T to 25T in Six Months
OpenRouter — the multi-model gateway sitting between agents and providers like Anthropic, OpenAI, Google, xAI, and DeepSeek — raised $113M Series B led by CapitalG at a ~$1.3B valuation, with NVIDIA, ServiceNow, MongoDB, Snowflake, and Databricks Ventures all participating.
The multi-model gateway hits $1.3B as Alphabet's growth fund bets on the routing layer between agents and 400+ providers.

What is it?
OpenRouter is a hosted gateway that exposes 400+ AI models from Anthropic, OpenAI, Google, xAI, DeepSeek, and others behind a single API and unified billing. The Series B is led by Alphabet's CapitalG, with NVentures (NVIDIA), ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures, AMP PBC, Pace Capital, Andreessen Horowitz, and Menlo Ventures all on the cap table.
How does it work?
Apps point at OpenRouter's API, choose a model (or let OpenRouter route on price, latency, or capability), and the gateway handles failover, retries, spend caps, and a single invoice across providers. Six months ago the platform was moving ~5 trillion tokens a week; it now does ~25T, and is on pace to clear 1 quadrillion tokens in 2026 across 8M+ developers. Enterprise features include workspaces, guardrails, spend controls, and zero-data-retention routing.
Why does it matter?
Every infra-as-a-service VC arm of the post-cloud era — NVIDIA, ServiceNow, MongoDB, Snowflake, Databricks, plus Alphabet — just bought into the same thesis: enterprises are done with single-vendor model lock-in. OpenRouter's growth rate (5x in six months) is one of the clearest data points yet that production AI workloads are converging on multi-model architectures, and that the routing layer between agents and providers is becoming load-bearing infrastructure.
