The Hundred: Birmingham Phoenix vs MI London

Platform comparison

Market context

The Hundred cricket tournament will host Birmingham Phoenix against MI London on 12 August 2026 at Edgbaston. Polymarket currently prices this contract at 0% YES, reflecting either extreme confidence in one side or minimal trading volume at present. The settlement window closes on 19 August 2026 at 17:30 UTC, allowing five days post-match for official results to be confirmed. Any decisive outcome—whether through standard play, Duckworth-Lewis-Stern adjustments, Super Over resolution, or administrative ruling—will settle the market according to the winner declared by the ECB's official match records.

Historical Hundred seasons show Birmingham Phoenix and MI London operate at markedly different competitive levels. Phoenix finished fourth in 2024 with a 5-3 record, whilst MI London placed seventh with a 2-6 record. Head-to-head records favour Phoenix, though The Hundred's compressed format and weather-dependent English summer conditions create volatility that generic win-loss ratios understate. Squad composition shifts annually, and injury absences announced in July or early August typically shift market pricing substantially once confirmed.

Traders should monitor team announcements in late July regarding overseas player availability and domestic squad selections. Weather forecasts for Birmingham on 12 August will influence pitch conditions and toss importance. Any late withdrawals or ground-related disruptions—rare but material—would affect conditional token mechanics on Polygon. The 0% current price suggests either illiquidity or strong consensus; meaningful volume entry typically occurs within two weeks of match day once squad sheets are finalised.

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

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.

UK Frequently Asked Questions

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 does Polymarket cost to trade?

Is Polymarket legal in the UK?

Do I pay tax on prediction market profits in the UK?

Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
