The Pandemic 2026 market asks one yes-or-no question across any pathogen: will the World Health Organization declare any disease a pandemic before the year is out? It sits inside a new-outbreak board carrying more than $1.7M in cumulative volume across Kalshi and Polymarket. The bar is higher than it looks. The WHO has had a Public Health Emergency of International Concern active since May 17, 2026 for the Ebola Bundibugyo outbreak in the Democratic Republic of the Congo, and that alert on its own does not resolve this contract Yes. The live board above ranks the current cross-platform prices; the market resolves December 31, 2026.
The Pandemic 2026 contract is a binary public-health question with a deliberately high bar, and 2026 has already stress-tested it. The World Health Organization determined on May 17, 2026 that the Ebola outbreak caused by Bundibugyo virus in the Democratic Republic of the Congo and Uganda constituted a Public Health Emergency of International Concern, the highest formal alert available under the International Health Regulations. The No side is still the heavy favorite here, because a PHEIC is not a pandemic declaration and this contract pays only on the latter. The distance between the alarm the WHO has actually sounded and the specific word this contract requires is the entire trade.
This market is pathogen-agnostic. It does not name a disease. It resolves on whether the World Health Organization declares any disease a pandemic during the 2026 calendar year, regardless of which virus or outbreak triggers it. It sits inside a larger new-outbreak board where disease-specific contracts trade on their own pages, so the line here reflects the aggregate risk that something, anything, crosses the WHO declaration threshold this year, while a single-pathogen page reflects only that one disease.
The dominant real-world input since this page was last reviewed is the Bundibugyo outbreak in the DRC, now the largest Ebola epidemic ever recorded in that country. As of August 16, 2026 the DRC had 4,966 confirmed cases and 2,327 confirmed deaths, a case fatality rate near 47%, with spread from a single health zone in Ituri province to 54 health zones across six provinces. Uganda declared its arm of the outbreak over on July 28, 2026 after 20 confirmed cases and two deaths, and a single imported case in France, a doctor returning from humanitarian work in the DRC, recovered. There is no approved vaccine for the Bundibugyo strain. The WHO initially advised against deploying Ervebo, which targets Zaire ebolavirus, then authorized a Phase 3 trial on July 31, 2026, with candidates in expedited development at IAVI, Moderna, and Oxford.
None of that has pushed the Yes side up. Both books opened June in double digits on this contract and both had drifted into the mid single digits by mid-August, with the Kalshi-to-Polymarket gap narrowing from roughly 3c to about 1c over the same stretch. A real, fast-moving epidemic escalated and the market got more confident in No, not less.
The reason is the WHO's own classification ladder. PHEIC is the top formal designation in the International Health Regulations. "Pandemic" is not a defined tier in that framework at all. It is descriptive language a Director-General chooses to use, last applied to COVID-19 in 2020. The WHO moved unusually fast on Ebola, declaring the PHEIC in the early morning of May 17, 2026 before convening an Emergency Committee, which had never been done before, and it has still kept the pandemic label off the table. Ebola's transmission profile is why: it requires direct contact with bodily fluids rather than sustained airborne spread, which produces devastating regional epidemics without the global sustained transmission that pandemic language describes.
The calendar is the other half of the read. With roughly four and a half months left before the December 31, 2026 close, the window for a qualifying declaration narrows every week. What the price reflects, then, is less a forecast of any single outbreak and more the market's read on institutional thresholds across every active health threat at once, weighted by the time left to cross one. The number moves when the WHO, national health ministries, or the CDC change their public posture on a developing situation. Absent that, this behaves like a slow, low-probability binary that the live board above prices day to day. Kalshi runs the broad question under its KXNEWOUTBREAK series and Polymarket lists a parallel new-pandemic contract; the Kalshi platform profile covers how its event contracts settle.
The market resolves December 31, 2026. It resolves Yes if the World Health Organization declares any disease a pandemic between January 1, 2026 and December 31, 2026 at 11:59 PM ET, with official WHO announcements as the named source of truth. A regional outbreak, a Public Health Emergency of International Concern, or a rising case count without that pandemic-level declaration does not by itself resolve the contract Yes. The active Ebola PHEIC is the live example: it is the WHO's highest formal alert, it has been in force since May 17, 2026, and it does not settle this market. If no qualifying WHO pandemic declaration occurs by the resolution date, the market resolves No.
For the pathogen-specific version of this question, see the Ebola pandemic 2026 odds, which isolates the disease currently driving the WHO's active emergency rather than the any-pathogen board on this page. For another public-health threshold contract, the measles cases 2026 odds track whether the U.S. logs at least 10,000 measles cases this year.

Resolves December 31, 2026. The market resolves Yes if the World Health Organization declares any disease a pandemic between January 1, 2026 and December 31, 2026 at 11:59 PM ET, with official WHO announcements as the named source of truth. The contract is pathogen-agnostic: any disease can trigger it. A regional outbreak, a Public Health Emergency of International Concern, or a rising case count without a qualifying WHO pandemic-level declaration does not resolve the contract Yes on its own, which is why the Ebola Bundibugyo PHEIC declared on May 17, 2026 has not settled this market. If no qualifying WHO declaration occurs by the resolution date, the market resolves No. Each contract pays out per platform-specific rules on the side that matches the outcome.
As of August 17, 2026 the Yes side trades at 5c on Kalshi and 6c on Polymarket, a consensus near 5.5c, down from double digits on both books in early June. The board carries more than $1.7M in cumulative volume, and the live board above shows the current cross-platform prices.
It resolves December 31, 2026. The contract resolves Yes if the World Health Organization declares any disease a pandemic between January 1 and December 31, 2026, with official WHO announcements as the source of truth.
It is available on both Kalshi, under the KXNEWOUTBREAK outbreak series, and Polymarket, which lists a parallel new-pandemic contract. The gap between the two books has narrowed to about 1c since June, but compare the lines on the live board above before treating them as a clean pair.
No. The World Health Organization determined the Ebola Bundibugyo outbreak in the DRC and Uganda a Public Health Emergency of International Concern on May 17, 2026, which is the highest formal alert under the International Health Regulations, but it is not a pandemic declaration. Only explicit pandemic-level language from the WHO settles this contract Yes.
Watch whether the DRC outbreak spreads beyond the 54 health zones it had reached by mid-August 2026 and whether any new transmission chain appears outside central Africa, since both feed the WHO posture that would trigger a Yes. The Phase 3 Bundibugyo vaccine trial authorized July 31, 2026 and the shrinking calendar into the December 31, 2026 close are the slower signals keeping No priced as the favorite.
