Next leader out of power before 2027? (No Orban)

Platform comparison

Market context

The real-world event driving this market is the permanent removal of a sitting head of state or government from office before the end of 2026, excluding Viktor Orbán, whose departure was already confirmed by Péter Magyar’s April 2026 election victory in Hungary. With Orbán’s exit settled, the board now focuses on leaders such as Gustavo Petro in Colombia and Keir Starmer in the UK, whose political positions face tangible instability.

Historically, markets resolving on permanent removals have been shaped by election losses, impeachment with removal, or forced resignations following scandals, rather than temporary suspensions like Yoon Suk Yeol’s recent impeachment. In Colombia, Petro’s 49.5% implied probability reflects deep unrest, while Starmer’s 34% stems from Labour’s crushing council election losses to Reform UK and mounting pressure for early leadership change, mirroring past democratic fragility before year-end.

Traders should monitor scheduled election dates, parliamentary votes on leadership, and official announcements of resignation or removal, as these are the only catalysts that trigger resolution. Recent council election results in the UK, where Reform UK defeated Labour in multiple key areas, have intensified calls for Starmer’s departure, a development cited by political analysts as a critical dependency for market movement before December 2026. Programmatically, conditional orders should be set to activate on confirmed election outcomes or formal removal notices, bypassing temporary suspensions that do not meet the market’s permanent removal criteria.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Review UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
