Trader consensus on Polymarket strongly favors no new pandemic in 2026, with an 88.5% implied probability, driven by CDC and WHO surveillance data confirming no novel pathogen has achieved sustained human-to-human transmission at global scale through mid-April. Despite ongoing H5N1 avian influenza outbreaks in wild birds, poultry, and mammals—prompting CDC's low public health risk assessment absent key mutations—human cases remain sporadic and non-transmissible between people. Localized epidemics, including global dengue (CDC Level 1 alert), meningococcal disease in the Democratic Republic of Congo (Level 2), and yellow fever in Venezuela, lack the exponential spread defining a pandemic per WHO criteria. Recent ECDC reports through early April show stable epidemiological patterns, bolstering "No" sentiment, while upcoming surveillance updates and WHO funding appeals underscore vigilant monitoring amid persistent zoonotic risks.
