Who will be in the Burnham cabinet?

Platform comparison

Market context

Andy Burnham has already unveiled his first Cabinet, confirming John Healey as Chancellor, Angela Rayner as Housing Secretary, and Shabama Mahmood as Home Secretary, while Ed Miliband takes Foreign Secretary and Louise Haigh returns as First Secretary of State [1][2][3]. This real-world appointment means the listed individual is confirmed as a minister, locking the Polymarket contract at 100% YES with no remaining uncertainty on the underlying event.

Historically, UK Cabinet formations after a new Prime Minister’s appointment resolve within days, with conditional tokens on Polygon settling once the Monarch confirms appointments within the seven-day window [2]. Past transitions, such as Starmer’s 2024 Cabinet, saw immediate price convergence to 100% for confirmed ministers, mirroring today’s USDC-traded contract where liquidity has evaporated as the outcome became certain [1].

Traders should monitor the official Monarch confirmation scheduled within the next seven days, though announcements are already public via the New Statesman live blog and ITV News [1][2]. No further catalysts exist beyond the formal appointment deadline of 11:59 PM UTC on the seventh day, as all key roles are already filled and no reappointments are pending [2]. The settlement window ending 2026-12-31 allows time for administrative finalisation, but the market’s 100% probability reflects the completed Cabinet list.

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 Kalshi UK, 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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi 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.
