The Hundred, Women: London Spirit vs MI London

Platform comparison

Market context

The real-world event is a women’s Hundred match between London Spirit and MI London, and the 62% crowd-implied **YES** is consistent with a fairly open contest rather than a strong favourite. The last completed meeting between these sides in this season finished **tied 151-151**, with ESPN noting that honours were shared after a dramatic final-over finish, so a market priced above 50% for one side to win is mainly reflecting the chance that one team converts a close game into a full result rather than another dead heat[1][8][9].

That framing matters because historical head-to-head has been tight but not uniform. Female Cricket’s recent comparison shows London Spirit had won the three completed meetings before the 2026 tie, while MI London were still winless in the tournament at the time of that report, which helps explain why a platform quoting decimal odds would translate this market more transparently into a price near 1.61 for YES, while a platform showing implied probability makes the same view easier to read at 62%[7]. On Betfair, Smarkets and similar exchanges, the headline probability is only part of the story because commission and back/lay spreads change the effective price; on Polymarket, the market price is closer to the displayed probability, but access and KYC reach can differ from exchange books.

For traders, the key catalysts are the confirmed XI, toss, and any weather or interruption risk, because The Hundred’s match rules treat ordinary on-field rulings, DLS/DRS, and forfeits as wins for settlement, while a tie resolves via any competition-approved on-field tiebreak if available. The most recent ESPN report also underlines that MI London were already under pressure for their first win and Spirit were still chasing consistency, so late team news and bowling changes matter more than broad season form when deciding whether 62% is too short or too long[1][2][8].
