Trader consensus favoring "No" at 83.5% for a new pandemic before 2028 stems primarily from sustained low global transmission of novel pathogens, as confirmed by WHO and CDC surveillance through September 2026. Ongoing outbreaks such as mpox (moderate risk, over 1,000 monthly cases) and Bundibugyo virus disease in the DRC remain regionally contained with case fatality ratios under 50% and no sustained human-to-human chains outside affected zones. Endemic COVID-19 circulation shows stable, low severity amid population immunity. The 2025 WHO Pandemic Agreement and International Health Regulations amendments have strengthened early detection, with 4.2 million signals verified in 2025 enabling rapid containment. While zoonotic spillovers and climate-driven factors elevate longer-term risk, current model consensus and absence of exponential growth in confirmed cases support the market-implied odds over the remaining 15-month window.
