OpenRouter doubles valuation to $1.3B after $113M Series B
OpenRouter, an AI gateway startup founded in 2023, raised $113 million in a Series B round led by CapitalG, the growth fund of Alphabet. The New York Times reported the round values OpenRouter at about $1.3 billion post-money, up from an estimated $547 million a year earlier after a $40 million Series A in June 2025. OpenRouter provides a multi-model gateway offering access to 400+ models (including Anthropic, Google, OpenAI, xAI and DeepSeek) and says it serves roughly 8 million users while processing about 100 trillion tokens per month. The funding and metrics underscore demand for model-agnostic inference infrastructure and a shift toward multi-model and agent-driven AI workflows.
A large Series B and roughly $1.3B valuation (led by CapitalG/Alphabet) signal strong investor interest in multi-model inference infrastructure; the company's reported scale (100T tokens/month, 8M users) highlights growing enterprise demand for model-agnostic AI gateways, a notable trend for AI infrastructure providers.

Stripe reportedly to buy OpenRouter for $7B+
Stripe has agreed to acquire OpenRouter, the 2023 model‑routing startup co‑founded by Alex Atallah, combining Stripe’s payments scale with OpenRouter’s model‑routing and usage‑based billing infrastructure. Terms were not disclosed; media reports range roughly $7B–$8B+ (some outlets cite ~$7.5B including founder payouts), below earlier ~$10B talks and implying about a 50× multiple on OpenRouter’s annualized revenue (~$140M). OpenRouter routes calls across 400+ third‑party models, automates model selection by cost/speed/performance, handles ~55 trillion tokens/week, charges an approximate 5.5% platform fee, serves millions of developers and provides tools like Ori Eval. It raised $113M in a May Series B at ~ $1.3B valuation (>$150M total raised) and will operate independently after closing, deepening Stripe’s AI orchestration and usage‑based billing capabilities. Reporting cites anonymous cap‑table sources and notes investor Anjney Midha backed the team in 2025 (page metadata: 2026‑08‑20).
