New pandemic in 2026?
🗂 Part of event: New pandemic in 2026? →💡 What the odds say
The market puts this at about a 7% chance — very unlikely.
No money — just record your call and see if you were right. Yes is at 7% right now.
Despite a 94% No price, the market is not pricing in the real risk of a WHO pandemic declaration from a non-COVID pathogen like Ebola or Legionnaires', which are currently active and escalating.
📊 Base rate: Since 2009, the WHO has declared a pandemic only twice (H1N1 in 2009, COVID-19 in 2020), giving a historical base rate of roughly 12% per year, meaning the current 7% Yes is slightly below that prior.
What's driving it
- • Ebola is moving faster than the response, according to the Africa CDC head (The New Humanitarian, Jul 9), raising the chance of a WHO emergency declaration that could escalate to pandemic status.
- • A Legionnaires' outbreak in New York is linked to climate threats (The Guardian, Jul 9), but Legionnaires' is not typically declared a pandemic by WHO, so this headline likely reinforces the No case.
- • An Oxford professor's warning that 'the next pandemic is not a matter of if, but when' (Euronews, Jul 8) keeps long-term concern alive but does not change the 2026-specific odds.
The case for YES
- • Ebola outbreaks in DR Congo and elsewhere are accelerating, and the Africa CDC warns the response is lagging (The New Humanitarian, Jul 9), which could lead to a WHO pandemic declaration if it spreads across multiple regions.
- • The WHO has already declared the DR Congo Ebola outbreak a 'public health emergency of international concern' (BBC, Jul 1), and a further escalation to pandemic is possible if containment fails.
- • Climate change is increasing the risk of new disease outbreaks, as seen with Legionnaires' in New York (The Guardian, Jul 9), and a novel pathogen could emerge and meet WHO pandemic criteria.
The case for NO
- • No WHO pandemic has been declared for any disease since COVID-19 in 2020, and the current Ebola and Legionnaires' outbreaks remain localized and have not triggered a pandemic declaration.
- • The WHO's pandemic definition requires global spread, and current outbreaks like Ebola in DR Congo and Legionnaires' in New York are geographically contained (BBC, Jul 1; The Guardian, Jul 9).
- • The market heavily discounts a 2026 pandemic at 94% No, reflecting the low probability of any single disease meeting WHO's strict criteria within the calendar year.
What to watch
- • WHO emergency committee meeting on Ebola in DR Congo (likely within weeks) — if it declares a Public Health Emergency of International Concern, it could increase Yes odds.
- • Any new WHO announcement of a disease spreading to a second continent with sustained transmission — would likely push Yes odds up.
- • End-of-year WHO summary report (December 2026) — if no pandemic declared by then, No odds will solidify further.

When will Starship flight 14 happen?
The field is extremely front-loaded: the top candidate (before 2027-04-01) commands 95% odds, and all ten candidates above 5% stack into the next nine months, reflecting a market consensus that Flight 14 is imminent but not immediate. The largest recent shift is the collapse of near-term dates after the July 17 abort, when the 'before 2026-10-01' candidate dropped from ~80% to 71% following a second launch abort.

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 extremely concentrated on 'any model announced before 2034' at 88%, but the long tail of 22 candidates above 5% suggests bettors see many plausible paths to a 1900-rated human being beaten by a future LLM, with the single biggest recent shift being the 2025-08-15 Business Insider report that OpenAI's o3 swept a chess tournament against xAI's Grok 4, likely boosting confidence in near-term AI chess ability.

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 top-heavy with SpaceX and Anthropic, but the recent reemergence of SPACs (Freshfields, Jul 24) provides a potential alternative route for lower-odds candidates like Kraken, Canva, and Stripe, making the race more dynamic than the leaderboard suggests.

GPT-6 released by ...?
The field is highly concentrated on two late-2026 dates, with 80% on December 31 and 68% on September 30, but the recent release of GPT-5.6 Sol (Northeast Times, Jul 25) and a security incident where models escaped testing (ABC News, Jul 22) have likely pushed the July 31 date to just 1%, making a near-term release seem very unlikely and anchoring expectations to later quarters.
