Perfect score achieved by an AI model in the International Math Olympiad (IMO) 2026?
💡 What the odds say
The market puts this at about a 97% chance — almost certain.
No money — just record your call and see if you were right. Yes is at 97% right now.
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.
📊 Base rate: Before 2026, no AI system had ever scored 100% at the IMO; the prior probability for any given year was effectively zero, making the current odds a dramatic break from history.
What's driving it
- • France 24 (Jul 23) and Taipei Times (Jul 23) both report that AI scored 100% at the top math contest, directly confirming the event.
- • XenoSpectrum (Jul 24) specifically states this is the first perfect score at the IMO, reinforcing the uniqueness of the achievement.
- • Multiple Chinese outlets (finance.biggo.com, Storyboard18) name Huawei and Xiaohongshu models as the specific AI systems achieving the perfect score, adding credibility from corporate claims.
The case for YES
- • At least four independent news outlets (France 24, XenoSpectrum, Taipei Times, News of Bahrain) all report the same outcome, suggesting a confirmed result.
- • The named models from Huawei and Xiaohongshu imply real, verifiable submissions to the IMO, not just benchmark tests.
- • The IMO is a well-known, standardized competition, so a perfect score is a clear, objective milestone that can be easily verified by the market.
The case for NO
- • The reports might refer to a different, non-official 'AI track' at the IMO, not the main human competition, which could affect the definition of 'perfect score achieved by an AI model'.
- • No single official IMO press release or statement has been cited yet, leaving a small chance of a correction or disavowal.
- • The near-unanimous market belief (97%) paradoxically means that any remaining uncertainty is extremely low, but it is not zero until the market resolves.
What to watch
- • Official IMO organization announcement or press release confirming the perfect score (Jul 26?): likely to lock in Yes at 100%.
- • Statement from a major AI lab (e.g., DeepMind, OpenAI) claiming credit or correcting the attribution: could shift odds slightly if they dispute the model's performance, but direction is unclear.
- • Verification by independent mathematicians or a detailed breakdown of the AI's solutions (within days): would reinforce Yes, pushing odds to 100%.

How it resolves
Resolved by whoever created the market, at their discretion per the question's description. It's play-money (Mana) and not tied to an official source — treat it as a community forecast.
ⓘ 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.

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.

Which of these Language Models will beat me at chess?
The field is highly concentrated on the near-term horizon, with the top three candidates all betting on a model announced before 2034, 2033, or 2032, collectively summing to 251% — but the real story is the steep drop-off after 2030, suggesting traders see a narrow window for a breakthrough, not a long march.

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.

Companies to go public in 2026
The field is moderately concentrated with two strong leaders—SpaceX and Anthropic—but a long tail of eight candidates above 5% makes it less a binary race than a bet on whether the two favorites both IPO or only one. The biggest recent shift is the emergence of congressional insider trading reports around SpaceX (CNBC, Jul 3), which may have boosted confidence that the IPO is real and imminent.

GPT-6 released by ...?
The field is extremely concentrated on a year-end release (Dec 31 at 69%), with the only recent movement being a secondary deadline (Sep 30) gaining ground, likely because the White House has asked OpenAI to limit the GPT-5.6 model in 2026 (Memeburn, Jul 3), implying regulatory pressure could delay a full GPT-6 beyond the summer.

By which flight will SpaceX successfully recover both Starship and its Booster?
The field is highly concentrated on flight 20 at 85%, but the recent successful V3 reentry validation on flight 12 (SpaceQ, May 24) and the loss of the booster on flight 12 (TechCrunch, May 22) show that booster recovery remains the harder challenge, keeping the door open for later flights if flight 20 fails.
