Toronto Tempo vs. Golden State Valkyries

Platform comparison

Market context

The Toronto Tempo face the Golden State Valkyries in a WNBA game scheduled for 4 August, and the crowd has Toronto at **14%** to win, which is far below the prices implied by conventional sportsbooks. On decimal-odds books, the Valkyries are trading around 1.10 to 1.11 on the moneyline, with Toronto typically quoted between 6.50 and 6.90, which corresponds to an implied win chance for the underdog in the low-to-mid teens before vig is stripped out.[4][6]

That makes this a fairly standard comparison case for reading prediction-market pricing: Polymarket quotes the event in cents and implied probability, while Kalshi, Betfair and Smarkets usually present decimal or exchange-style prices that require a quick conversion to probability. The key distinction is that prediction markets and exchanges can show a lower headline price for the favourite or underdog depending on fees and liquidity, but the underlying read is the same: Toronto is a long shot, and the market is broadly consistent with sportsbook moneylines that have Golden State as a heavy favourite.[1][2][10][14]

For traders, the main catalysts are pre-game injury or lineup news, any late change to the start time, and whether the WNBA schedule slips into postponement risk, because the market stays open until the game is completed if it is delayed. Recent previews and odds boards have kept the spread around Golden State -13.5 and the total in the mid-160s to high-160s, so any shift in those numbers, or a move in the Valkyries’ moneyline towards or away from about -850 to -950, would be the clearest signal that fresh team news has changed the probability.[1][3][5][14]
