How this market settles
What could still go wrong
- If the CDC counter becomes unavailable, the market description states 'another credible source will be used' without specifying which source, introducing potential dispute about which alternative source qualifies.
- The market end date is January 1, 2027 at 04:59 UTC, but the resolution window ends December 31, 2026 at 11:59 PM ET (which is January 1, 2027 at 04:59 UTC) — these appear consistent but the CDC may update counts after the resolution timestamp, potentially creating timing ambiguity.
- It is unclear whether the CDC counter reflects only cases with onset dates within 2026 or cases reported/confirmed within 2026, which could affect the count at resolution time.
