No money — just record your call and see if you were right. Yes is at 1% right now.
The market is virtually certain hantavirus will not become a pandemic in 2026, despite recent outbreaks and expert warnings, because the virus lacks efficient human-to-human transmission and current outbreaks have been contained.
📊 Base rate: Hantavirus has never achieved sustained human-to-human transmission sufficient for a pandemic in recorded history, placing the current 1% odds above the empirical base rate of near zero.
What's driving it
- • The WHO declared the recent cruise ship outbreak over (Forbes, Jul 2), demonstrating containment and reducing pandemic fears.
- • Experts have explicitly stated that the hantavirus outbreak is 'not another Covid pandemic' (CNBC, May 14), reinforcing the low probability.
- • COVID-era public health measures and heightened awareness may be helping to control outbreaks (NPR, May 21), limiting spread.
The case for YES
- • The increasing frequency and damaging potential of hantavirus and other infectious diseases (The Guardian, May 18) could lead to a larger, uncontrolled outbreak.
- • The virus caused a notable outbreak on a cruise ship (Forbes, Jul 2), showing it can spread in confined settings, which might escalate if containment fails.
The case for NO
- • The cruise ship outbreak was declared over by the WHO (Forbes, Jul 2), indicating effective containment and no sustained spread.
- • Experts characterize the current hantavirus situation as testing U.S. readiness but not a pandemic threat (CNBC, May 14), highlighting limited transmission risk.
- • There is no evidence of efficient human-to-human transmission for hantavirus, a critical barrier to pandemic status.
What to watch
- • No specific upcoming events are mentioned in the provided headlines; a new report of human-to-human transmission would increase Yes odds, while a successful vaccine trial would decrease them.

BNB Up or Down - Daily
The market's 70% odds for BNB rising today are not obviously supported by any of the provided recent headlines, which predominantly cover Airbnb regulatory news and a single crypto-related price drop from five months ago.
Yes ≈ 74% chance
Los Angeles Daily Temperature High (81)
The market prices just a 2% chance that Los Angeles saw exactly 81°F on July 25, 2026—a reflection of both the inherent rarity of any specific integer temperature and the context of an unusually hot spring that tilted the distribution upward.
Yes ≈ 2% chance
Los Angeles Daily Temperature High (81)
The contract for LAX on July 25, 2026, has effectively already resolved to No, with odds at 2% reflecting the observed high temperature below 81°F. The earlier heatwave headlines (March–April) do not directly explain this outcome, as the specific day did not meet the threshold.
Yes ≈ 2% chance
Will over 100,000 people be conceived with the help of advanced embryo selection techniques by 2030?
The market sees advanced embryo selection as still niche and ethically fraught, but recent coverage of genetic optimization startups and IVF's expanding role in family planning suggests the technology is gaining momentum, making the 100,000-conception threshold plausible if regulatory and adoption barriers fall.
Yes ≈ 26% chance
Los Angeles Daily Temperature High (81)
This market is effectively resolved: the event date (July 25, 2026) has passed, and the overwhelming 98% No odds indicate that actual temperature readings have already shown the high was not exactly 81°F, with final confirmation likely the only remaining step.
Yes ≈ 2% chance
