Whenever WotC announces that a card is banned from Standard, that card will resolve YES. At market close, any unbanned cards will resolve NO.
Update 2025-11-10 (PST) (AI summary of creator comment): Resolution timing clarification:
Cards that get banned during the year will resolve YES when announced
All other unbanned cards will not be resolved to NO until the end of the calendar year (market close on 2026-01-01)
This creates a "rolling market structure" where new bans resolve immediately but non-banned cards remain open until year end
Screaming Nemesis and Proft’s also banned but not on the list— gotta try to keep more candidates in there.
For market mechanics, I won’t resolve the others as NO until the end of the calendar year, then I’ll make a new one. This might disincentivize negative bets but I think the rolling market structure is good overall compared to the one-off ban announcement markets.
(Although one could argue that this round of bans in particular demonstrates that they’re not going to be doing many off-cycle bans.)
