The ongoing Bundibugyo virus outbreak in the Democratic Republic of the Congo, now the country’s largest ever with over 6,000 confirmed cases and nearly 3,000 deaths as of early September 2026, continues to drive trader sentiment toward a 57.5% implied probability of a new country reporting a case before October 1. Active conflict, high population mobility through mining areas, and incomplete contact tracing have enabled spread across multiple provinces, sustaining concerns about further cross-border transmission despite Uganda declaring its imported outbreak over in July. Recent modeling and WHO updates highlight elevated risks to neighbors like South Sudan, though no fresh confirmations have emerged in the past month. Traders are watching daily surveillance reports and any late-August or September case clusters near borders as key catalysts that could shift odds before the deadline.

The "current outbreak" is the Bundibugyo ebolavirus outbreak declared by the DRC on May 15, 2026. A "qualifying country" is any country other than the Democratic Republic of the Congo, Uganda, or France, each of which had recorded at least one confirmed case attributable to this outbreak as reported by Centers for Disease Control and Prevention (CDC) https://www.cdc.gov/ebola/situation-summary/index.html.
A "confirmed case" is a laboratory-confirmed Bundibugyo ebolavirus infection attributed to the current outbreak. A case counts for whichever country the qualifying source assigns it to in its reporting, regardless of where exposure, symptom onset, or specimen collection occurred. Resolution turns on the date a qualifying source publishes the confirmation — not the date of exposure, onset, or laboratory result. A report published after the deadline does not count even if the infection occurred earlier.
The primary resolution sources for this market will be official information from the relevant national and international health authorities, including CDC and the World Health Organization (WHO); however, an overwhelming consensus of credible reporting will also suffice.
