**Rapid progress by OpenAI’s GPT-5.6 series has pushed the leading FrontierMath v2 Tiers 1-3 score to 89% as of late August 2026, placing the 90% threshold within striking distance before year-end.** The benchmark’s June 2026 v2 update corrected errors in roughly 42% of problems, lifting scores across the board while preserving relative rankings and revealing faster underlying capability gains than earlier v1 numbers suggested. OpenAI models have dominated recent leaderboards, with GPT-5.6 Sol, Terra, and Luna variants occupying the top spots on both Tiers 1-3 and the harder Tier 4 set. Continued scaling of reasoning effort, iterative Python tooling, and expected late-2026 model iterations from OpenAI and competitors support trader expectations that the final percentage point will be cleared in the remaining months of 2026. The 89% market-implied probability for Yes aggregates this demonstrated trajectory and near-term release cadence.
