OpenAI’s recent launch of ChatGPT Images 2.5 on September 8 has driven its dominant 90% implied probability, as the update delivers sharper details, up to 50% faster generation, and markedly improved precision editing that better preserves subjects, lighting, textures, and prior changes across multiple conversational turns. New tools like Sketch references and direct image comments enable more reliable object-level or background revisions without unintended drift, quickly elevating the models (including API variants Sunburst and Flare) to the top of independent image-editing leaderboards. Other entrants such as Google’s Nano Banana family, Black Forest Labs, and various Chinese labs trail in current trader consensus because they lack comparable recent advances in iterative editing stability. With the October resolution still weeks away, further model updates or benchmark shifts remain possible but have not yet materialized to challenge OpenAI’s lead.

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.
