The Hundred: Birmingham Phoenix vs MI London

Platform comparison

Market context

The Hundred's 2026 edition will feature Birmingham Phoenix against MI London on 12 August at Edgbaston, a twenty-over format match where the current 0% YES probability on Polymarket reflects either extreme confidence in MI London or minimal liquidity in the contract. The settlement mechanism treats any on-field ruling—including DLS adjustments, over-rate penalties, or Super Over outcomes—as a legitimate win, meaning weather interruptions or administrative decisions won't void the market. This contract resolves on 19 August, a week after play, allowing time for any post-match clarifications or official record updates.

The Hundred has operated since 2021 with relatively consistent team compositions and venue dynamics. Birmingham Phoenix's home advantage at Edgbaston historically favours sides familiar with the ground's dimensions and pitch behaviour, though The Hundred's compressed format can neutralise traditional home-ground edges through variance in short-form cricket. MI London's franchise recruitment and recent tournament form will determine whether they field a squad capable of challenging Phoenix's familiarity advantage. The 0% probability suggests traders view this as heavily one-sided, though The Hundred's twenty-over format produces unexpected results at higher rates than longer formats.

Key catalysts include squad announcements and injury updates in the weeks preceding the match, typically released by the ECB or franchises in late July. Weather forecasts for Birmingham on 12 August will influence perceived match completion risk, particularly given England's summer conditions. Any late team changes, player unavailability, or venue adjustments would shift the underlying odds; traders should monitor official ECB communications and franchise social media for these developments.

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.
