The Hundred, Women: London Spirit vs MI London

Platform comparison

Market context

The Hundred women’s London derby between London Spirit and MI London is priced by the market as a **62% yes** to the named outcome, which is broadly consistent with a slight favourite rather than a commanding one. The latest comparable meeting finished all square: MI London made 151 for 4 and London Spirit replied with 151 for 5, a tie at the Kia Oval on 29 July 2026, with Spirit’s Amy Jones and MI’s Amelia Kerr among the standout performers.[1][6][8]

Historical context points to this being a volatile fixture rather than a one-sided one. One preview noted that London Spirit had won the previous three completed head-to-heads before that draw, including an eight-wicket win in 2025 and another sizeable victory in 2025, but the same source also recorded the 2024 tie, underlining that the derby has produced both clear wins and near-identical finishes.[9][10] For readers comparing platforms, Polymarket-style markets usually show a plain implied probability, whereas Betfair and Smarkets quote decimal odds and then deduct commission, so the same 62% view can translate into different effective prices after fees; Kalshi’s U.S.-facing access is also shaped by KYC and jurisdictional checks, which matters if you are comparing liquidity rather than just the headline probability.

For this specific market, the main catalysts are the final team news, toss, and any late weather or schedule change around the August 6 fixture at Lord’s, as those can materially affect a short-format match where one innings can decide the result.[2][9] If the contest is shortened or interrupted, the market terms say DLS/DRS, over-rate penalties, walkovers, or any on-field ruling that produces a winner count as ordinary wins, while a tie is only resolved by an on-field tiebreak if the playing conditions provide one. That means traders should focus on whether both sides name full-strength bowling attacks and whether the official match conditions permit a Super Over-style decider, because that determines how a tie is settled in practice.
