According to data from Kalshi, a federally authorized betting platform, over $7.6 million has been bet on the contract "Best AI at the end of 2026?" Bettors have placed a 65.2% probability that Anthropic’s Claude will emerge as the best AI at the end of 2026, up by 2.7%, while ChatGPT comes in second with a probability of 14.6% and Gemini is third with a probability of 10.2%. Anthropic last week launched Opus 5, its latest AI model, which it says delivers major improvements in software engineering, business automation and scientific research, claiming that Opus 5 offers double the performance of Opus 4.8 on Frontier-Bench while lowering the cost per task. Separately, Nvidia is reportedly considering backing $250 billion in financing to support OpenAI’s massive AI infrastructure expansion, part of a data center project in southern Ohio that could cost more than $500 billion.
