Who will Trump endorse?

Who will Trump endorse? is a political prediction market centered on whether Donald Trump will publicly announce an endorsement for the listed election and, if so, which candidate he will support. The market resolves based on official information from Trump or his representatives, or on a consensus of credible reporting of his endorsement. If no endorsement is announced by the day before the scheduled election at 11:59 PM ET, the market resolves to "No."

This event matters because a Trump endorsement can shape campaign narratives, media coverage, and voter expectations in a closely watched election cycle. Traders are forecasting the expected outcome by weighing Trump’s statements, campaign signals, and broader market sentiment around the race. The current market probability is 100%, indicating the market is fully priced toward an endorsement outcome being recognized by the contract rules, though that does not guarantee any specific candidate will be named.

The prediction market is active from September 12, 2025 through November 4, 2026, giving participants a long runway to assess political developments, endorsement timing, and election-day deadlines.
