7 Jan
Summary
- LMArena secured $150 million in Series A funding.
- The startup achieved a $1.7 billion post-money valuation.
- It previously raised $100 million in a seed round.

Emerging from UC Berkeley research in 2023, LMArena announced a substantial $150 million Series A funding round, achieving a post-money valuation of $1.7 billion. This capital infusion, led by Felicis and UC Investments, dramatically escalates the startup's financial standing shortly after its $100 million seed round in May, which valued it at $600 million. In total, LMArena has raised $250 million in approximately seven months.
The company initially gained prominence for its crowdsourced AI model performance leaderboards, accessible via its consumer website. Users submit prompts, compare model outputs, and contribute to data spanning over 5 million monthly users globally. These evaluations cover a wide array of AI tasks, including text generation, web development, and image creation, testing models from major players like OpenAI, Google, and Anthropic.
LMArena has expanded its commercial operations with an AI Evaluations service, allowing enterprises to commission model assessments. This initiative has already generated an annualized recurring revenue of $30 million as of December. The startup's rapid growth and the critical role of its benchmarks have attracted significant venture capital interest.
