Trader consensus for an 81.5% implied probability of no new pandemic before 2028 stems primarily from the absence of any pathogen currently exhibiting sustained human-to-human transmission with pandemic potential, per WHO and CDC monitoring. Regional threats such as Bundibugyo Ebola (declared PHEIC in May 2026 but contained in DRC and Uganda), avian influenza A(H5) with low overall public health risk, and rising dengue or mpox cases remain localized without evidence of efficient airborne spread or rapid global escalation. Post-COVID surveillance enhancements, rapid sequencing capabilities, and historical patterns of contained zoonotic spillovers support this outlook, though climate-driven vector expansion and preparedness gaps introduce ongoing uncertainty ahead of upcoming WHO assessments.
