Resolution criteria on PolyGram: 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.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Will Kamala Harris announce a 2028 run for President by June 30? | 2% YES | 98% NO |
Harris currently serves as Vice President under Joe Biden, with the 2024 presidential election having concluded in November 2024. The question centres on whether she will publicly declare her candidacy for the 2028 presidential race before 30 June 2026—a window of approximately 18 months from the settlement date. An official announcement through any channel (speech, statement, or authorised representative communication) triggers resolution to Yes; filing formal nomination papers is not required.
Historical precedent suggests sitting Vice Presidents typically signal 2028 intentions within this timeframe if they intend to run. The 2% implied probability on Polymarket's order book reflects substantial scepticism about an early declaration. Harris's political positioning following the 2024 election outcome, combined with the extended runway until the 2028 campaign season formally begins, creates conditions where many traders assess a delayed announcement as more probable. Early declarations carry strategic risks including prolonged scrutiny and potential primary challenges, which may discourage pre-June 2026 announcements from sitting Vice Presidents.
Key catalysts include any major policy announcements or legislative victories Harris champions that could signal campaign positioning, statements from Biden administration officials regarding succession planning, and Democratic Party messaging around 2028 prospects. Traders should monitor Harris's public schedule and media appearances for language suggesting future electoral ambitions. The settlement window closes well before typical campaign announcement seasons, meaning the low probability reflects genuine uncertainty about whether Harris would move faster than historical norms for sitting Vice Presidents.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
