The market heavily discounts a WHO pandemic declaration for hantavirus in 2026, despite a recent cruise ship outbreak and quarantine stories, reflecting the WHO's historical reluctance to use the 'pandemic' label since COVID-19.
What's driving it
- • The July 23 cruise ship outbreak (Newswise) raised awareness of hantavirus but did not trigger any WHO pandemic statement, reinforcing the low odds.
- • A Reuters fact check (July 20) debunked viral misinformation about a Simpsons prediction, showing the public's heightened but misguided attention to hantavirus.
- • A PBS article (May 14) noted that COVID-19's legacy makes the WHO and countries cautious about overusing the pandemic label, reducing the likelihood of a declaration.
- • The Guardian report (July 22) on CDC cuts suggests reduced U.S. preparedness, but that does not directly push the WHO toward a pandemic declaration.
The case for YES
- • The 42-day quarantine ordeal (NYT, July 21) illustrates the severity of hantavirus disease, which could prompt WHO action if cases multiply globally.
- • The cruise ship outbreak (Newswise, July 23) shows hantavirus can spread in confined settings, raising the risk of broader transmission that might meet WHO's pandemic criteria.
- • If the WHO's International Health Regulations Emergency Committee convenes and declares a PHEIC, the market could interpret that as a step toward an explicit pandemic characterization, though PHEIC alone is insufficient per rules.
The case for NO
- • The WHO has not characterized any hantavirus outbreak as a pandemic historically, and the current outbreak remains isolated to a single cruise ship (Newswise, July 23) with no evidence of sustained community spread beyond that.
- • The PBS article (May 14) highlights that COVID-19's legacy makes the WHO cautious about declaring new pandemics, so the bar for using the term is extremely high.
- • Despite the cruise ship and quarantine stories, no official WHO communication has mentioned hantavirus as a pandemic threat, suggesting the agency sees it as a localized outbreak.
What to watch
- • Any future WHO press briefing or official statement that explicitly mentions hantavirus in the context of a pandemic would increase the odds (positive direction).
- • If a new hantavirus cluster emerges in a second country, especially linked to the cruise ship cases (Newswise, July 23), odds would rise (positive direction).
- • If no new significant outbreaks are reported globally by the end of Q3 2026, the odds will likely remain near current levels (negative direction).

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.

Resolution criteria
This market will resolve to "Yes" if the World Health Organization explicitly characterizes Hantavirus, Hantavirus Pulmonary Syndrome (HPS), Hemorrhagic Fever with Renal Syndrome (HFRS), or a Hantavirus-related outbreak as a "pandemic" in an official public communication between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". An explicit characterization includes official WHO statements, reports, press briefings, or publications that clearly describe the outbreak as a "pandemic." A Public Health Emergency of International Concern (PHEIC) alone will not qualify unless it is also described as a pandemic. The primary resolution source for this market will be official WHO communications. A consensus of credible reporting may also be used.
ⓘ 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.

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
