Which company has second best AI model end of June?

Which company has second best AI model end of June? is a Tech prediction market focused on the Chatbot Arena LLM Leaderboard and the company behind the model ranked second overall. The market will resolve using the "Text Arena | Overall" leaderboard at lmarena.ai, checked on June 30, 2026 at 12:00 PM ET, with rank determined first by the leaderboard position, then by Arena score if needed, and finally by company name as a tiebreaker. In plain terms, traders are forecasting which AI company will hold the No. 2 spot among large language models at the end of June. This matters because Chatbot Arena is a widely watched benchmark for comparing frontier AI systems from companies such as OpenAI, xAI, and other Big Tech participants. Current market probability sits around 91%, indicating strong market sentiment toward a consistent expected outcome, though that forecast is not guaranteed. The event attracts attention from traders tracking AI model performance, Big Tech competition, and shifting rankings in the gpt and broader AI category. If the leaderboard is temporarily unavailable, the market remains open until the first available check after service is restored.
