Background :
LMArena, an artificial intelligence startup that began as a research project at the University of California, Berkeley, has reached a valuation of $1.7 billion after raising $150 million in a Series A funding round.
Venture firm Felicis and UC Investments, the university’s investment arm, led the round. The company raised the funding just four months after launching its commercial product, showing strong investor confidence in its fast growth.
UC Berkeley researchers founded LMArena in 2023 as Chatbot Arena. The company built its reputation with crowdsourced leaderboards that rank AI model performance. Its consumer platform lets users test two AI models with the same prompt and pick the one that works better. These user choices feed into public rankings that measure model performance across tasks such as writing, coding, vision, reasoning, and image generation.
The platform has grown quickly, drawing more than 5 million monthly users across 150 countries and hosting about 60 million conversations each month. It evaluates leading models from companies including OpenAI, Google, Anthropic, and xAI, as well as models designed for specialised tasks.
LMArena entered the commercial market in September with a service called AI Evaluations. The product allows enterprises, AI labs, and developers to test and compare models using feedback from the platform’s large community. The company said the service reached an annualised revenue rate of $30 million by December, less than four months after launch.
The startup had already raised a $100 million seed round in May at a $600 million valuation. With the new funding, LMArena has raised $250 million in about seven months.
The Series A round also drew backing from major investors, including Andreessen Horowitz, Kleiner Perkins, Lightspeed Venture Partners and others. The company said the fresh capital will support further growth of its evaluation tools and global user base.
