Will Kamala Harris announce a 2028 run for President by June 30?

This market will resolve to “Yes” if Kamala Harris officially announces that she is running for U.S. President in the 2028 United States presidential election by June 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. An announcement by Kamala Harris will be sufficient to trigger a "Yes" resolution, regardless of whether she actually filed a nomination to run, or whether she actually files a nomination to run in the future. The primary resolution source for this market will be official statements by Kamala Harris or her legal or social media representatives (ex: via speech, social media, etc.), however a consensus of credible reporting may also be used.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
