These markets collectively determine which AI company owns the best-performing large language model as of March 31, 2026, using the Chatbot Arena LLM Leaderboard as the authoritative ranking source. Polymarket offers granular binary outcomes for 26 specific companies/entities plus an 'any other' catch-all, while Kalshi provides binary YES/NO resolution for six major AI labs. Both platforms resolve based on the highest Arena Score on the leaderboard at the specified checkpoint time.
