OpenAI’s September 8 launch of ChatGPT Images 2.5, featuring 50% faster generation, superior multi-turn editing consistency, precise local edits via annotations or sketches, and stronger subject preservation from reference images, has driven its 78.5% implied probability. Recent arena leaderboards place its GPT-Image-2.5 variants at the top for editing tasks, reflecting trader consensus on demonstrated gains in complex scene stability and instruction adherence over prior versions. While Microsoft AI’s MAI-Image-2.6 series, Google’s Nano Banana models, and offerings from ByteDance and Reve remain competitive on broader benchmarks, the timing of OpenAI’s update ahead of the late-October resolution window has shifted sentiment decisively. No major competing releases have emerged in the past week to challenge this positioning.

This market will resolve according to the company that owns the model that has the highest rank based on the arena.ai Image Edit Leaderboard when the table under "Image Edit Arena" filtered for "Models" is checked on October 31, 2026, 12:00 PM ET.
Results from the "Rank" column under the "Image Edit Arena" Leaderboard tab at https://arena.ai/leaderboard/image-edit (Overall) filtered for "Models" will be used to resolve this market.
Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score. Models marked “Preliminary” at the applicable check time will be considered.
Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by which model is listed higher on the leaderboard. If a tie still remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., “Google” would be ranked ahead of “SpaceXAI”). This market will resolve based on the company that occupies first place under this ranking.
The resolution source for this market is the arena.ai Image Edit Arena Leaderboard. If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available.
