The Hundred: Birmingham Phoenix vs Sunrisers Leeds

Platform comparison

Market context

Birmingham Phoenix and Sunrisers Leeds were scheduled to meet at Edgbaston in a 100-ball men’s match on 7 August, and the crowd’s 0% YES price is only easy to read if it reflects a market that has already been decided or briefly mispriced against the live result. ESPN’s live and report pages show Sunrisers Leeds won by 45 runs, with Phoenix bowled out for 124 after Sunrisers made 169 for 7, and that result also eliminated Phoenix from the competition. [1][13]

For comparison, this fixture has usually been competitive enough to avoid near-certain pricing before the start: the teams traded results in earlier Hundred seasons, including Phoenix’s 86-run chase in 2024 and a Phoenix win in 2021, which is why pre-match books often move sharply on team news rather than on history alone. Sky Sports’ in-play model had Sunrisers at 69% once Phoenix were set 170 to win, underlining how quickly a 100-ball match can swing once a first-innings total is on the board. [3][4][15]

For traders, the main catalysts are the confirmed XI, the toss, and any rain or interruption scenario, because the market rules treat DLS/DRS, over-rate penalties and any official on-field win as ordinary settlement outcomes. On Polymarket this is usually shown as a binary implied probability, while on Betfair or Smarkets the same match is read through decimal prices and exposed to fees and liquidity differences; all three also differ on KYC access and who can actually place a bet in the first place. The Hundred’s official team pages and live coverage are the cleanest sources for late schedule or availability changes, and BBC/ESPN live pages are the quickest way to catch last-minute team announcements.
