Recent top scores on FrontierMath, including GPT-5.6 Sol near 89% on the legacy version and Claude Fable 5 at 87.8% on the updated Tier 4 v2 released in June 2026, have placed the 90% threshold within striking distance for frontier large language models. Traders cite ongoing rapid gains in mathematical reasoning through scaled training, specialized fine-tuning, and tool-augmented agents from labs like OpenAI and Anthropic. With several months remaining before 2027 and expected further model iterations or capability jumps, the 82.5% implied probability for “Yes” reflects strong consensus on continued momentum, tempered by the benchmark’s extreme difficulty and potential for timeline slips.
