This market will resolve to "Yes" if the CDC issues a Level 4 (“Avoid All Travel”) Travel Health Notice for any disease by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A Level 4 notice listed for any amount of time during this market’s timeframe will suffice for a "Yes" resolution. The primary resolution source for this market will be the CDC’s official Travel Health Notices page (https://wwwnc.cdc.gov/travel/notices); however, a consensus of credible reporting will also be used.Official monitoring by the CDC and agencies like the WHO shows multiple active outbreaks, including Bundibugyo virus disease in the Democratic Republic of the Congo at Level 3 and expanding chikungunya and dengue transmission, with case counts and transmission dynamics already approaching thresholds for escalation. Model consensus and historical patterns of similar filovirus or arbovirus events indicate a high likelihood of reaching extreme health risk criteria—where no effective precautions exist—within the remaining months of 2026. Trader consensus at 99.1% implied probability reflects this data trajectory and the agency's precedent for prompt Level 4 notices during rapid deterioration. Realistic shifts could still occur if enhanced surveillance, containment measures, or revised case reporting prevent further intensification before December 31.
