About This Event
In 2026 If any disease becomes a pandemic in 2026, then the market resolves to Yes. Early close condition: If this event occurs, the market will close the following 10:00 AM ET. If this event occurs, the market will close the following 10:00 AM ET.
What Prediction Markets Are Forecasting
Traders on Kalshi currently give a "Pandemic in 2026" about a 7% chance, or roughly 1 in 14 odds. That means the collective wisdom of the market thinks this is unlikely, but not impossible. For comparison, that's about the same odds as rolling a specific number on a standard die, or the chance that a random MLB player hits a home run in a given game. It's a low probability, but not so low that you'd dismiss it entirely.
The market is asking a simple question: will the World Health Organization declare a pandemic in 2026? That's a high bar. The WHO's declaration for COVID-19 came months after the virus had already spread globally. For a new pandemic to be declared in 2026, we'd need a novel pathogen to emerge and spread widely within the next year.
Why the Market Sees It This Way
Three factors explain the low odds.
First, pandemic declarations are rare events. Since 2000, the WHO has declared only two: H1N1 swine flu in 2009 and COVID-19 in 2020. That's two declarations in 25 years, which works out to roughly 8% per year. The market's 7% estimate aligns closely with that historical baseline.
Second, surveillance has improved dramatically since COVID-19. Wastewater monitoring, genomic sequencing, and global reporting networks are far more robust than they were in 2019. The WHO's new Pandemic Agreement, finalized in 2024, strengthens early warning systems. Better detection doesn't prevent pandemics, but it does mean containment happens faster, which often prevents a full pandemic declaration.
Third, the current disease landscape doesn't show an obvious candidate. Avian influenza H5N1 has been spreading among dairy cattle and occasionally infecting humans, but it hasn't demonstrated sustained human-to-human transmission. Mpox was declared a public health emergency in 2024, but it never reached pandemic status. Without a clear emerging threat, traders are betting we get through 2026 without a global outbreak.
Key Dates and Events to Watch
The market could shift quickly if any of these happen:
- A confirmed case of sustained human-to-human transmission of H5N1 or another avian flu strain
- A major outbreak in a densely populated region that overwhelms local health systems
- The WHO's quarterly pandemic threat assessments, which come out in January, April, July, and October
- Any new pathogen identified with pandemic potential in the scientific literature
If the odds start climbing above 15%, that would signal traders are seeing real signals. If they drop below 5%, the market is getting more confident in a quiet year.
How Reliable Are These Predictions?
Prediction markets have a decent track record with binary events like this. They've been reasonably accurate for elections, geopolitical events, and even disease outbreaks. But there's a catch: pandemics are inherently unpredictable. The 2019 markets had essentially zero probability for a global pandemic in 2020. The market is only as good as the information available, and novel pathogens by definition surprise us.
The 7% figure is best understood as a well-informed guess, not a precise forecast. It reflects the historical frequency of pandemics plus current disease surveillance data. For most people, the practical takeaway is straightforward: a pandemic in 2026 isn't the most likely scenario, but it's not something to completely rule out either.
Current Market Outlook
Kalshi traders price a 7% chance that a disease becomes a pandemic in 2026. That means the market sees this as a low probability event, roughly equivalent to a 1 in 14 shot. For context, this is notably higher than the roughly 3% to 4% odds markets assigned to a 2025 pandemic earlier this year, but still well below the 15% to 20% range seen during the peak of COVID-era uncertainty in 2020 and 2021.
The market's resolution criteria are straightforward: any disease that meets the World Health Organization's pandemic definition in 2026 triggers a Yes. That includes novel influenza strains, coronaviruses, or any other pathogen that spreads across multiple countries or regions with sustained community transmission.
Key Factors Driving the Odds
The 7% figure reflects a balancing act between historical frequency and current surveillance. The CDC and WHO have logged roughly four pandemics in the last 120 years: 1918, 1957, 1968, and 2009. That works out to about a 3% annual baseline. The market is pricing above that baseline for two reasons.
First, avian influenza H5N1 has been spreading through dairy cattle and poultry in the United States since early 2024, with sporadic human infections reported. Each spillover event gives the virus more chances to adapt to human transmission. Second, the post-COVID era has seen weakened surveillance infrastructure in many low-income countries, which delays detection of novel pathogens and gives them a head start on global spread.
What Could Change These Odds
The biggest catalyst is the upcoming flu season in the Northern Hemisphere, running from October 2026 through March 2027. If H5N1 continues its current trajectory of increasing mammal-to-mammal transmission, expect these odds to climb toward 12% to 15%. Conversely, a mild flu season and no major zoonotic spillover events through mid-2026 would likely push the probability down toward 4% to 5%.
The WHO's May 2026 World Health Assembly could also shift odds if member states announce new pandemic preparedness funding or accelerated vaccine production agreements. Historically, these announcements have a modest dampening effect on market probabilities, though they rarely move the needle more than 1 to 2 percentage points.
The market's 7% pricing suggests traders see pandemic risk as real but manageable, with current containment measures and vaccine platforms providing a meaningful, though not absolute, safety net.

Overview
The prediction market question 'Pandemic in 2026?' asks whether any disease will be officially designated a pandemic during the calendar year 2026. A pandemic is defined by the World Health Organization (WHO) as the worldwide spread of a new disease, though the term is also used colloquially for large-scale outbreaks of existing diseases. The market will resolve to 'Yes' if any disease meets this threshold in 2026, with early closure if the event occurs. This question taps into ongoing concerns about emerging infectious diseases, global health security, and the legacy of COVID-19, which was declared a pandemic on March 11, 2020, by WHO Director-General Tedros Adhanom Ghebreyesus. Since the COVID-19 pandemic, global surveillance systems have been strengthened, and the WHO has been revising its pandemic preparedness framework. The International Health Regulations (IHR) were amended in 2024 to include a 'pandemic emergency' tier, and negotiations for a pandemic treaty are ongoing. These changes reflect a heightened awareness of risks from zoonotic diseases, antimicrobial resistance, and climate change, which could facilitate the emergence of new pathogens. Interest in this market is driven by several factors: the cyclical nature of influenza pandemics (which have occurred roughly every 10-50 years), the recent outbreaks of avian influenza (H5N1) in mammals, the ongoing threat of new coronaviruses, and the potential for lab leaks or bioterrorism. The COVID-19 pandemic caused over 7 million reported deaths globally, but actual estimates are higher, and the economic toll was estimated in the trillions of dollars. This history makes the question of a future pandemic a matter of public concern and policy debate. While no one can predict exactly when the next pandemic will occur, experts like the WHO's Dr. Michael Ryan have stated that 'the next pandemic is a matter of when, not if.' The 2026 timeframe is specific, and the market's resolution criteria are clear: any disease meeting the WHO's definition or a similar international declaration would trigger a 'Yes' outcome. The market also includes an early close condition, meaning if the event occurs, trading ends the following day at 10:00 AM ET.
Historical Context
The history of pandemics is long and includes events like the 1918 influenza pandemic (Spanish flu), which killed an estimated 50 million people worldwide. More recent pandemics include the 1957 Asian flu (H2N2) and the 1968 Hong Kong flu (H3N2), both of which were caused by novel influenza viruses. The 2009 H1N1 pandemic was declared by WHO in June 2009 and was the first pandemic of the 21st century, though it turned out to be relatively mild. The COVID-19 pandemic, caused by SARS-CoV-2, was declared a pandemic on March 11, 2020. It led to unprecedented global lockdowns, the development of mRNA vaccines in record time, and over 7 million reported deaths (with excess mortality estimates suggesting 15-20 million). Since then, the WHO has been working on a pandemic treaty, and the IHR amendments adopted in 2024 aim to improve global cooperation in health emergencies. Other notable outbreaks that did not reach pandemic status include SARS (2003), MERS (2012), Ebola (2014-2016 in West Africa), and Zika (2015-2016). These events have shaped global health policy and highlighted the gaps in surveillance and response. The current avian influenza (H5N1) outbreak, which has affected birds and mammals, is being closely monitored as a potential pandemic threat if it gains human-to-human transmission capability.
Why It Matters
A pandemic in 2026 would have profound consequences for global health, economies, and societies. The COVID-19 pandemic caused a global economic contraction of 3.1% in 2020, the worst since the Great Depression, and cost trillions in stimulus packages and lost output. A new pandemic could similarly disrupt supply chains, travel, and trade, with particular impacts on low- and middle-income countries that have limited healthcare infrastructure. The social impact would include potential lockdowns, school closures, and mental health challenges, as seen in 2020-2021. Beyond the immediate health crisis, a pandemic would test international cooperation and could exacerbate geopolitical tensions, as seen with vaccine nationalism and the blame game during COVID-19. It would also accelerate changes in healthcare delivery, such as telemedicine and remote work, and drive further investment in biotechnology and pandemic preparedness. The outcome of the market is therefore not just an academic question; it reflects real risks that governments, businesses, and individuals must consider when planning for the future.
Current Status
As of early 2025, the world is still recovering from COVID-19, with millions of cases of long COVID and ongoing issues with new variants. The WHO has declared that COVID-19 no longer constitutes a public health emergency of international concern (PHEIC) as of May 2023, but it continues to be a global health threat. The current focus is on monitoring avian influenza (H5N1) outbreaks in dairy cattle in the United States, which have led to a few human cases. The CDC and WHO are on alert for any signs of human-to-human transmission. In terms of policy, the WHO's Intergovernmental Negotiating Body (INB) is working on a pandemic treaty, with a target to adopt it by May 2025. The amendments to the IHR, which include a new 'pandemic emergency' definition, are set to come into force in 2024. These developments are aimed at improving global preparedness and response, but implementation remains a challenge. The prediction market for a 2026 pandemic reflects the ongoing uncertainty and the scientific consensus that another pandemic is inevitable, though the timing is unknown.
Frequently Asked Questions
What is the definition of a pandemic?
A pandemic is defined by the WHO as the worldwide spread of a new disease. It is a higher level of alert than an epidemic, which is a disease outbreak that affects a large number of people in a specific region. The declaration is made by the WHO Director-General based on criteria including global spread and severity.
What diseases are most likely to cause the next pandemic?
Influenza viruses, particularly avian influenza (H5N1), are considered the most likely candidates due to their high mutation rate and ability to jump species. Other threats include coronaviruses (like SARS-CoV-2), Nipah virus, and new zoonotic diseases from wildlife. The WHO maintains a list of priority diseases for research and development.
