Will Z.ai have the best Math AI model at the end of July 2026?
🗂 Part of event: Which company has the best Text Arena Math AI model end of July? →💡 What the odds say
The market puts this at about a 0% chance — almost no chance.
No money — just record your call and see if you were right. Yes is at 0% right now.
Z.ai, a virtually unknown player, is given a 0% chance to top the Math Arena leaderboard by month's end, yet the rapid progress in math AI (exemplified by 85% odds on a perfect IMO score) and new releases like Grok 4.5 mean the leaderboard could shift—but all evidence points to established labs, not Z.ai, as the likely beneficiaries.
📊 Base rate: Historically, the top math model on the Chatbot Arena has always come from a major lab (OpenAI, Google, Anthropic, DeepSeek, Meta) or a large open-source effort, with no unknown startup ever holding the top spot in the past two years.
What's driving it
- • The zero percent odds reflect Z.ai's complete lack of public presence; there is no headline or rumor suggesting they are even developing a competitive math model (no recent coverage).
- • The release of Grok 4.5 by X.ai (Jul 8) demonstrates that major players are actively iterating, raising the bar that Z.ai would need to surpass.
- • The market's 85% odds on an AI perfect score at IMO 2026 (tech-insider.org, Jul 9) indicate widespread belief that math AI is accelerating, but that belief is tied to known labs, not Z.ai.
The case for YES
- • If Z.ai is a secretive start-up with a breakthrough model that has not been announced, it could debut and top the leaderboard before July 31, but no headline or leak supports this possibility.
- • Z.ai's model could be a rebranded or white-label version of another model that performs well, allowing it to claim the top spot under the resolution criteria (company that owns the model).
- • The leaderboard could be gamed or suffer from low traffic, enabling an obscure model to score well through targeted submissions, though this is speculative and ungrounded in any headline.
The case for NO
- • Z.ai has no public track record, no releases, and no coverage in recent headlines, while known competitors like X.ai (Grok 4.5, Jul 8) and the labs behind IMO-capable models are actively publishing results.
- • The market is pricing Z.ai at 0%, the lowest possible probability, indicating consensus that the chance is effectively zero—extremely difficult to overcome in the next three weeks.
- • Even if a new math AI breakthrough occurs (e.g., perfect IMO score), the credit would likely go to a recognized lab (OpenAI, Google, etc.) rather than Z.ai, as no headline connects Z.ai to such progress.
What to watch
- • Any announcement or leak of a Z.ai math model release before July 31 (would move odds up toward Yes).
- • A new top-ranked math model from a major lab (OpenAI, Google, Anthropic, X.ai) in the next three weeks (would solidify No and potentially increase No odds).
- • Publication of the Chatbot Arena math leaderboard update showing a sudden rise by Z.ai (highly unlikely given current odds, but would be a strong catalyst).

How it resolves
Settled on-chain by UMA's optimistic oracle: once an outcome is clear, anyone can propose the result, which then enters a challenge window where it can be disputed with evidence before it finalizes.
⚖️ A proposed outcome can be disputed during a challenge window before it's final.
Resolution criteria
This market will resolve according to the company that owns the model that has the highest arena rank based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab for "Math" is checked on July 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Math" Leaderboard tab at https://arena.ai/leaderboard/text/math-no-style-control with style control off 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 “xAI”). This market will resolve based on the company that occupies first place under this ranking. The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/. 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 based on another resolution source.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.

Perfect score achieved by an AI model in the International Math Olympiad (IMO) 2026?
Multiple news outlets report that AI models have achieved a perfect score at the 2026 IMO, making the 97% odds a near-certainty that the event has already occurred, with the market awaiting final formal confirmation.

Apple Announces AI Glasses by September 30, 2026
The field is moderately concentrated with the 'No' side leading at 62%, but the 45% sum for two candidates indicates significant overlap or mispricing; the biggest recent shift is Meta's June 23 launch of $299 smart glasses (Forbes, Jun 23), which likely boosted the 'No' side by making Apple's entry seem less urgent or unique.

Will Anthropic release its next Mythos-class model to the public by August 31, 2026?
Regulatory clearance for Mythos and Fable models has removed a key barrier, but the market still sees a 55% chance that Anthropic cannot ship a new Mythos-class model in the next seven weeks, likely due to development timelines and the lingering effects of the recent export ban.
Yes ≈ 46% chance
Companies to go public in 2026
The field is extremely concentrated on SpaceX and Anthropic, whose combined odds (161%) imply the market expects at least one of them to go public in 2026, but the lack of recent headlines about either company's IPO process leaves the high probabilities unexplained by concrete events.
