Market context
This market asks whether Donald Trump will publicly insult an individual on a single specified date between now and 31 August 2026. A YES share pays out if he does; a NO share pays out if he doesn't. The resolution hinges on direct, verifiable language—statements made in public settings, published by Trump himself, or recorded on the record to journalists. Private remarks that leak do not count, nor do paraphrased or summarised versions of his words.
The 100% implied probability reflects Trump's documented pattern of public insults across two decades of public life. Between his 2016 campaign, presidency, and post-2020 statements, Trump has regularly issued direct personal attacks on named individuals via rallies, press conferences, Truth Social posts, and media appearances. Historical data from fact-checkers and news archives show he has insulted political opponents, media figures, and public personalities on the vast majority of days when he has made public statements. This consistency underpins the market's current pricing, though the outcome remains contingent on whether Trump makes any public statement on the specified date at all.
Traders should monitor Trump's scheduled activities: campaign rallies, court appearances, Truth Social posting frequency, and media availability all influence the likelihood of a public statement occurring. Recent patterns show he maintains a high cadence of public remarks, particularly during election cycles and legal proceedings. Any announcement of a media blackout, health issue, or extended private period could shift the practical odds, though the market's current settlement window extends well into a period historically marked by frequent Trump public engagement.

Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
UK Frequently Asked Questions
- Where can I trade this market with the lowest fees?
- Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Prediction Market UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- Is Polymarket legal in the UK?
- Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.
- Do I pay tax on prediction market profits in the UK?
- UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
- How do I deposit on Polymarket from the UK?
- UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
