As written on Polymarket for “Donald Trump Jr. Republican nomination odds leader on October 31?”.
§1This market will resolve according to the option with the highest hourly odds value in the "2028 Republican Nomination" listing on PredictionMarketOdds.com for the "Time Window (ET)" ending at 12:00 PM ET on October 31, 2026.
§2If that option is not a listed outcome of this market, this market will resolve to "Other".
§3An hourly odds value is the value in the "Odds of Happening" column that PredictionMarketOdds.com publishes for an option for a one-hour "Time Window (ET)", as shown on the listing page and in the "Odds History" graph on that option's detail page.
§4Hourly odds values are compared at the precision published by PredictionMarketOdds.com (one tenth of a percent).
§5If PredictionMarketOdds.com publishes "NO_PRINT" for an option for the specified window, that option's most recent published hourly odds value before the specified window will be used.
§6If PredictionMarketOdds.com has not published anything for the specified window for an option (neither an hourly odds value nor "NO_PRINT"), this market will remain open until a value or "NO_PRINT" for that window is published, and may remain open until November 7, 2026, 11:59 PM ET for that purpose.
If nothing has been published for the specified window by that time, that option's most recent published hourly odds value before the specified window will be used.

§7
§8An option with no hourly odds value published in that period will not be considered.
§9If two or more options are tied for the highest value, the tie will be broken in favor of the tied option with the higher value in the most recent earlier window in which their values differed.
§10If the tie persists, this market will resolve in favor of the tied option whose listed name comes first alphabetically.
§11If the underlying market is officially decided before the listed end date, this market will resolve in favor of the outcome of the underlying market if it is a listed outcome, and otherwise to "Other".
§12If a published hourly odds value is clearly erroneous as a result of a technical or operational error, this market may remain open for up to an additional 48 hours after that value is first published to allow for a correction.
§13A corrected value will be used in place of the original.
§14If no correction is published within that period, the original value will stand, and revisions published after that period will not be considered.
