The Hundred: London Spirit vs Birmingham Phoenix

Platform comparison

Market context

London Spirit have already won the men’s fixture against Birmingham Phoenix at Lord’s, with Spirit chasing down 162 for four to win by seven wickets and 18 balls to spare. That result was part of a broader day at the ground that also saw Spirit’s women beat Phoenix, leaving very little uncertainty in the live match state and reinforcing why the crowd is effectively pricing this market as a completed outcome.[3][1]

That 100% implied probability fits the recent head-to-head pattern at Lord’s, where margins have swung from a low-scoring three-wicket Phoenix win in 2024 to a 77-run Phoenix win later in the 2025 campaign, before Spirit turned the tables in 2026.[6][10][3] In Hundred markets, once a result is in the books the settlement risk usually shifts away from match uncertainty and towards administrative edge cases such as abandonments, scoring corrections or delayed official confirmation, but none of those alter a plainly recorded winner in ordinary circumstances.[3][8]

The main live catalysts now are procedural rather than sporting: confirmation that the official scorecard remains unchanged, whether any post-match review affects the recorded result, and the competition’s final publication of the fixture outcome before the market’s settlement window closes on 16 August. The match was scheduled for Lord’s and the live score sources show Spirit electing to bowl first, which is consistent with the final result already reflected in the coverage.[16][19][3]

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
