The Hundred, Women: Welsh Fire vs London Spirit

Platform comparison

Market context

Welsh Fire will face London Spirit in a women's Twenty20 match on 12 August 2026 as part of The Hundred domestic competition. The Polymarket contract currently prices YES at 98%, reflecting strong confidence in a decisive outcome rather than a tied result. This probability reflects the conditional token mechanics on Polygon: traders holding YES tokens profit if either team wins via standard play, DLS adjustments, over-rate penalties, or any on-field tiebreak mechanism including a Super Over. The settlement window closes on 19 August, allowing six days post-match for official confirmation and any regulatory rulings.

The 98% YES price sits at the extreme end of historical Hundred women's match distributions. Tied results in The Hundred format are genuinely rare—the competition's Super Over provision means most matches resolve decisively rather than ending level. Comparable women's T20 domestic tournaments show tied matches occur in roughly 1–3% of fixtures, which aligns with the 2% implied probability for NO (a tied result with no tiebreak winner). This pricing reflects structural features of the format rather than team-specific weakness.

Traders should monitor team news through early August, particularly injury updates affecting either squad's batting depth or bowling options, as these influence match competitiveness. Weather forecasts for the venue become relevant in the final week before play. The ECB's official fixture confirmation and any ground-specific playing conditions amendments should be checked against the market's settlement criteria, particularly regarding Super Over protocols if the match reaches that stage.

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?

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

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. 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.
