Trump out as President by July 31?

Platform comparison

Market context

Donald Trump resigning or being removed from the presidency before 31 July 2026 remains an exceptionally low-probability event, with crowd-implied odds at just 1% YES. Historically, no US president has ever been successfully removed via the 25th Amendment or impeachment during their term, with the 1868 Andrew Johnson case narrowly failing by a single Senate vote. Kalshi currently estimates Trump’s removal probability at nearly 28.7% for his second term, a sharp rise from earlier in the year, yet this still reflects a high barrier given Republican control of both congressional chambers. Without a two-thirds majority in the Senate—requiring 67 votes—the constitutional threshold for removal remains unattainable under current political realities.

Traders should monitor any formal announcements from House Democrats regarding impeachment articles, as well as scheduled votes on removal efforts before the March 31 legislative deadline. Recent reports suggest Democrats are two votes short of advancing a major removal effort, though these claims lack confirmation from official legislative sources. Key catalysts include potential invocation of the 25th Amendment Section 4, which demands written notice to congressional leaders and a 21-day congressional deliberation window. On-chain, whale flows into BTC and ETH may signal macro risk sentiment, while USDC settlement volumes on prediction platforms could reflect shifting confidence. Exchange spot funding rates and crypto data from sources like Kalshi or Lines.com offer real-time sentiment indicators for this contract.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

How does UMA secure the resolution?

The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.

How volatile are crypto prediction markets?

Crypto markets react to spot prices — a 5% BTC move typically shifts a "BTC above X by date" market 10-20%. Polymarket crypto market liquidity is usually six-figure USD, sufficient for active trading.

Which crypto markets exist on Polymarket?

Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.
