Traders assign an 80% implied probability against a new pandemic before 2028 because historical patterns show major global events occur infrequently, with the last occurring in 2020 and prior ones separated by years or decades. Current conditions support this view: WHO assessments place COVID-19 risk at moderate amid high population immunity and stable Omicron lineages, while H5N1 avian influenza shows no sustained human-to-human transmission despite animal exposures. Localized outbreaks of mpox, Ebola, Marburg, and Nipah remain contained without meeting pandemic thresholds, bolstered by post-2020 surveillance improvements and progress on the WHO Pandemic Agreement. Model consensus and official monitoring indicate low near-term spillover risk, though viral evolution and climate-driven vector shifts introduce uncertainty ahead of 2028.
