The market-implied odds of 87.5% against a new pandemic before 2028 reflect sustained global surveillance showing no pathogen with sustained human-to-human transmission capable of widespread international disruption. The primary driver is the ongoing Bundibugyo Ebola outbreak in the Democratic Republic of the Congo and Uganda, declared a PHEIC in May 2026 with thousands of cases but managed regionally through vaccination campaigns and contact tracing without pandemic-scale spread. Supporting conditions include the 2025 WHO Pandemic Agreement strengthening detection and response capacity, alongside other monitored threats like Nipah, avian influenza, and dengue that remain localized or seasonal. Historical patterns indicate most emerging zoonoses produce contained epidemics rather than global events, and current model consensus and case data show no rapid escalation trajectory through late 2026.
