Market context
Donald Trump Jr.’s second wedding is due over Memorial Day weekend, and the market resolves on whether Donald Trump is physically present at any point during the event. The 5% yes price implies traders think a trip is possible but still unlikely, which is consistent with a narrow resolution rule: even a brief appearance counts, but any cancellation, postponement beyond 30 June, or absence leaves the market at No. For programme-style trading, the key is that the window is short and binary, so conditional orders tend to cluster around fresh confirmation rather than gradual drift.
Comparable Trump family appearances usually trade on proximity, security, and scheduling rather than sentiment alone. A President or former President can change plans quickly if there is a competing public commitment, travel constraint, or last-minute change to the family event itself. That makes the market sensitive to low-latency reporting: even before formal confirmation, traders often lean on pool reports, local press, and photographer calls. A recent Reuters item also noted Trump’s own comment that attending would be “not good timing”, which helps explain why the crowd price has stayed in low single digits rather than moving towards parity.
The practical watchlist is simple: official White House or Trump schedule releases, any travel notices, the family’s own social posts, and credible local coverage from the wedding venue area. If a press schedule shows him elsewhere that weekend, the No side hardens quickly; if travel to the venue is pencilled in, the Yes price can re-rate fast because physical attendance is the only settlement trigger. For users automating alerts or copy-trading, the cleanest setup is a ruleset keyed to headline keywords such as “attend”, “wedding”, “travel”, and “schedule”, with immediate execution only if a source meets the market’s reporting standard.

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
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.
