3.
What counts as Yes
Seat / Electoral CertificationRequires the candidate to win and accept the party's nomination (normally at the convention); leading in delegates or polls is not enough. A later replacement of the nominee does not change the result. Rule text: "This market will resolve to “Yes” if the named individual wins and accepts the 2028 nomination of the Republican Party for U.S. president. Otherwise, this…"
4.
Backup rules (delays, cancellations, revisions)
No fallback or data-provider hierarchy stated in the rules. Trap: no stated deadline for uncalled races, recounts or court challenges; settlement can wait on certification, and media calls can conflict with official results.
5.
Fine print and other venues
Cross-venue & fine-print settlement trap: Polymarket settles on a consensus of credible reporting with null deciding if ambiguous; certified official results can lag media calls by weeks. Venues that settle only on certified results can resolve later, or differently if recounts change the outcome.
