OPENAI'S PRESIDENT SAYS AGI MAY HAVE ALREADY ARRIVED, AND THAT THIS IS THE MODEL • • Greg Brockman told reporters that in a couple of years, when people look back and ask when AGI was created, he thinks the answer will be around now and possibly this model. • • OpenAI launched GPT-6 Astra Thursday and calls it the world's best computer use model. In the company's own tests it booked DMV appointments, searched job listings, and apartment hunted faster than the average person. • • Rollout starts with enterprise clients in the Daybreak early access program, then ChatGPT Plus, Pro, and Business. No word on free users. • • OpenAI is racing toward a planned IPO. So is Anthropic.

How did this market resolve?
This market will resolve according to the company which owns the model which has the highest arena rank based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab is checked on September 30, 2026, 12:00 PM ET.
Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and filtered for "Models" will be used to resolve this market.
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 their Arena score, including any underlying, unrounded, granular values reflected in the data below 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., if the two models are tied by exact arena score, “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 Text Arena (Overall). 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. If it becomes permanently unavailable, this market will resolve to "Other".
