Key lines from the rules (Polymarket)

“An outcome is considered unconditionally determined if it would have been guaranteed under every possible completion of the match played according to the match format…”
“If the match is permanently abandoned before completion, or if the match has not been completed by November 23, 2026, 11:59 PM ET, this market…”
