Who will be in the Burnham cabinet?

Platform comparison

Market context

Andy Burnham has confirmed his first Cabinet following his appointment as Prime Minister, with John Healey taking the Treasury, Ed Miliband moving to Foreign Secretary, and Louise Haigh returning as First Secretary of State. The full list, published by the New Statesman and Standard, shows Shabana Mahmood retaining Home Secretary and Lucy Powell appointed Education Secretary, while the Department for Science, Innovation and Technology has been scrapped entirely[1][2].

Historical precedent for new UK Prime Ministers suggests near-universal confirmation of key ministers within the first week, with the 100% crowd-implied probability on this contract reflecting the standard rapidity of royal appointments after a PM’s swearing-in. Comparable cases from recent transitions, such as Sunak’s 2022 cabinet, show minimal divergence between initial announcements and final Monarch confirmations, making a “No” outcome exceptionally unlikely unless an individual is explicitly excluded from the list[1][3].

Traders should monitor the official royal proclamation scheduled for Monday, when Burnham formally becomes PM, and the subsequent 24-hour window for appointments to be sealed by the Monarch. The Standard’s live list already names all qualifying cabinet members, including new AI Minister Kanishka Narayan and Scotland Secretary Douglas Alexander, with no pending vacancies that would alter the outcome[2]. Any delay beyond the seventh-day cutoff would be the sole catalyst for resolution failure, but current reporting indicates all selections are finalised[4].

Methodology

This page reviews Who will be in the Burnham cabinet? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Kalshi vs Polymarket, which mirrors the Polymarket order book at 0% fees.

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

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.

Do I need to KYC for this market?

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