Current trader consensus on Polymarket, with “No” at 89.5 percent, reflects the absence of any novel pathogen demonstrating sustained global human-to-human transmission through mid-May 2026. Official WHO and CDC surveillance data show contained clusters, including a recent hantavirus outbreak linked to a cruise ship that produced limited person-to-person spread via respiratory droplets and no exponential growth. Ongoing mpox clade IIb cases and sporadic H5N1 avian influenza infections remain localized without meeting pandemic thresholds. Global monitoring systems continue to track zoonotic spillovers and respiratory threats, but half the year has elapsed without the emergence of a virus capable of rapid worldwide dissemination, consistent with historical patterns of contained outbreaks rather than full-scale epidemics.
