Market context
Polymarket prices **1% YES** on this contract, so traders are treating a Trump departure by 31 August 2026 as an extreme tail event rather than a live baseline case.[2] On Polymarket, shares settle in **USDC** on **Polygon**, and the winning side is redeemable for **$1** once the market resolves, which makes the price a direct read on the crowd’s implied odds.[2][8]
The historical read-through is that resignation-or-removal markets usually stay pinned near the floor unless there is a concrete, official trigger. This contract is also narrowly written: it pays on resignation, permanent removal, or otherwise ceasing to be President for any period by the deadline, but *temporary* transfer of power does not qualify, and an announcement before expiry would resolve it immediately even if the departure takes effect later.[2] That structure matters because traders are not pricing “political trouble” in the abstract; they are pricing a specific, settlement-grade event.
For a hands-on Polymarket user, the key catalysts are official White House statements, any resignation announcement, and any formal removal process that becomes public before the deadline.[2] An MSN report noted a brief surge in resignation speculation ahead of a White House announcement, which shows how quickly the order book can react to event risk even when the underlying probability remains low.[1] In practice, the market is most sensitive to schedule-driven headlines, not rumour alone, because conditional tokens on Polygon only settle when the rule language is satisfied.[2][8]
Methodology
This page is a comparison snapshot: one live quote, 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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
