Artificial intelligence models are multiplying fast, and competition is stiff. With so many players crowding the space, which one will be the best — and who decides that? Arena, formerly LM Arena, has emerged as the de facto public leaderboard for frontier LLMs, influencing funding, launches, and PR cycles. In just seven months, the startup went from a UC Berkeley PhD research project to being valued at $1.7 billion. 

Watch as Equity host Rebecca Bellan catches up with Arena co-founders Anastasios Angelopoulos and Wei-Lin Chiang about how their platform became the go-to leaderboard for frontier AI models, and how they’re trying to build a neutral benchmark even as companies like OpenAI, Google, and Anthropic back the project.

What good is a vaccine people don’t trust? Immunologist and TED Fellow Kizzmekia Corbett co-developed the first COVID-19 vaccine to enter clinical trials — but she says making the vaccine was never the hardest part. The real obstacle is the gap between scientists and the people who have honest questions about the shots they’re being asked to take. She shares a refreshing approach for taking on vaccine inquisitiveness and ensuring that humanity is ready for the next pandemic. (Recorded at TED2026 on April 15, 2026)
