**Current trader consensus favoring "No" at 78.5% reflects the absence of any novel pathogen showing sustained human-to-human transmission capable of global spread within the narrow 15-month window to 2028.** Ongoing regional outbreaks, such as the Bundibugyo Ebola virus disease declared a PHEIC by WHO in May 2026 across DRC and Uganda, remain geographically limited with no evidence of efficient airborne or sustained international transmission. Similar patterns hold for mpox clusters in Africa and isolated investigations into respiratory illnesses, none of which meet pandemic thresholds. Enhanced post-COVID surveillance by WHO, CDC, and ECDC, combined with historical infrequency of novel pandemics, supports the market-implied odds, though model uncertainty around zoonotic spillovers like H5N1 avian influenza persists. Key upcoming data points include continued WHO emergency committee reviews and seasonal influenza surveillance updates.
