Trump out as President by August 31?

Platform comparison

Market context

Donald Trump leaving office before 31 August 2026 is a low-probability event in both the market and the broader political baseline. Polymarket currently shows **1% YES** on this contract, which is materially below the 7.5%–8% range cited on longer-dated “out before 2027” markets on other venues, suggesting traders are discounting the shorter deadline sharply even while keeping a small tail risk alive.[1][3][10] That gap is consistent with an event that would require an abrupt resignation, formal removal, death, or another permanent cessation of office rather than a temporary transfer of power.[1][4]

Historically, prediction-market pricing on presidential departure events has tended to stay low until a concrete trigger appears, then reprice quickly on verified reporting or an official statement. Comparable Trump-resignation markets have been described as lingering in the low single digits before news-driven spikes, which is why a 1% reading should be read as “remote but not impossible” rather than as a genuine consensus on near-term stability.[2][12] On the cross-platform picture, there is no sign of a broad analyst consensus for imminent departure; the current spread is best understood as Polymarket pricing a tighter time window than the more extended departure contracts elsewhere.[1][10]

The main catalysts are straightforward: any formal resignation statement, a removal action that is publicly confirmed, or an official announcement that he will cease to be president, because the market resolves immediately on announcement rather than on the effective date.[1] Traders should also watch the White House schedule, any sudden changes in medical or security-related briefings, and breaking coverage from major outlets that could establish an official confirmation event. More broadly, recent prediction-market coverage has focused on personnel churn inside the Trump administration rather than Trump’s own office status, which reinforces the current market’s view that the presidency itself is unlikely to change hands by late August.[5][8]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

FAQ

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
