Will CMI declare the Riemann Hypothesis solved by ___?
The chance that CMI officially declares the Riemann Hypothesis solved by the end of 2026 is extremely low. The market price looks generous relative to the tiny amount of time left and the historical difficulty of the problem.
Analysis
The current market implies about a 6.5% chance of a Yes outcome, but that still looks high given what would actually be required. CMI would need not only a genuine breakthrough on one of mathematics’ most famous open problems, but also enough confidence to make an official declaration or award before the end of 2026. With no fresh news indicating a credible near-term breakthrough, the default assumption should remain that nothing material changes before expiry.
The Riemann Hypothesis has been open for more than a century and sits near the top of the difficulty ladder even among Millennium Prize problems. A solution is not just a matter of public announcement; it must survive expert scrutiny and then be formally recognized by CMI, which adds another layer of delay and caution. Even if someone posted a convincing argument tomorrow, the odds that CMI would complete its review and issue an official statement within a few months are still very low.
Arguments for Yes exist mainly in the form of tail risk: mathematics can surprise, a proof could already be circulating privately, and a decisive result from a major researcher or institution could force rapid attention. But the base rate overwhelmingly favors No, because breakthroughs on problems of this stature are rare and official resolution is slower still. In practice, the most likely outcome is that the year ends with no CMI declaration, and the market price appears to reflect more speculation than near-term probability.
Arguments
For
- A genuine breakthrough could already exist and only need formal recognition from CMI.
- If a credible proof appears from a top mathematician or institution, CMI could accelerate its evaluation.
Against
- The Riemann Hypothesis has resisted solution for decades despite intense effort from the mathematical community.
- Even a real proof would still need time for verification before CMI could officially declare it solved.
Key drivers
- There is no reported evidence of a credible near-term proof or official CMI review in progress.
- The remaining time window before year-end is too short for discovery, verification, and formal declaration.
- The Riemann Hypothesis is historically one of the hardest unsolved problems in mathematics.
Risk factors
- A privately developed proof could surface unexpectedly and move quickly through expert review.
- A false rumor or overconfident public announcement could temporarily make a resolution look more imminent than it is.
Scenarios
Best case
A highly credible proof of the Riemann Hypothesis emerges early enough for experts to validate it, and CMI issues an official statement or award before year-end.
Most likely
There is continued interest and occasional claims or speculation, but no universally accepted proof and no qualifying CMI announcement before the deadline.
Worst case
No convincing proof appears, or a claimed proof fails verification, and CMI ends 2026 without any official declaration.

Will Anthropic flip BTC by December 31?
AI2%MKT77%Edge-75HypedAnthropic flipping Bitcoin by the end of 2026 looks extraordinarily unlikely. The valuation gap is so large that it would likely require a once-in-a-generation private funding event for Anthropic and a major Bitcoin drawdown at the same time.

"Spider-Man: Brand New Day" total domestic gross by August 31? (Higher Strikes)
AI25%MKT84%Edge-59HypedMy read is that Spider-Man: Brand New Day is more likely to finish above 900M domestically by August 31 than below it. I put the chance of less than 900M at about 25%, because the film is already so far along that only an unusually sharp slowdown would keep it under the line.

The main uncertainty is whether the market resolves on de facto elimination or requires formal statutory abolition, but I still see a Yes outcome as more likely than not.
