Portland is the 56c home favorite on Polymarket and Seattle sits at 46c across both books (47c on Kalshi, 45c on Polymarket), a narrow price for a game between a 12-19 expansion side and a 6-27 Storm team that has lost 10 straight. Kalshi's Seattle contract implies the Fire at 53c, so the two exchanges disagree by 3c on the same outcome. The spread is Portland -1.5 at 51c and the total pivots at 180.5 points with the over at 52c. Current prices are on the live board above.
Portland is the home favorite at 56c and the market is treating this as close to a coin flip, which is the most interesting thing about a matchup between a first-year expansion team and the worst record in the league. The Portland Fire are 12-19 and 7-9 at Moda Center. The Seattle Storm are 6-27 and 2-16 on the road, and they have lost each of their last 10 games. Tip is 8:30 PM ET on August 8, 2026, in Portland, and the group carries roughly $5.2K in combined volume across the two exchanges.
The moneyline is the cleanest read on the board. Seattle trades at 47c on Kalshi and 45c on Polymarket for a 46c average, while Polymarket prices the Fire side directly at 56c. Back out the Kalshi number and its Seattle contract implies Portland at 53c, a 3c gap against Polymarket's 56c on the same outcome. That is the value spot on this game: the Fire are cheaper expressed through the Kalshi Seattle contract than they are bought outright on Polymarket. Depth is thin on both sides, with $3.2K of total volume on the Kalshi moneyline against $426 on Polymarket, so the Kalshi side is where the price is actually being set.
The price held through the pre-game window. Kalshi's Seattle contract printed 47c at the open of the snapshot series and 47c at the latest read, with no intermediate move. Polymarket drifted a single cent, 44c to 45c, over the same stretch. This is a market that formed and stayed put, which is what a low-volume WNBA game between two non-contenders usually looks like.
Form favors Portland without much argument. The Fire beat Toronto 97-83 on August 6, their third win in the last 10, and they are averaging enough offense to have topped 95 points in four of their last six. Carla Leite is the usage hub at 15.9 points and 6.4 assists per game, with Emily Engstler leading the team at 5.3 rebounds. Seattle counters with Dominique Malonga, who is the best individual player in the building at 16.9 points, 8.7 rebounds and 1.3 blocks per game, backed by Natisha Hiedeman at 4.7 assists. The Storm have scored 83, 86, 89 and 95 in their last four losses, so the shortfall is not a total collapse on offense, it is a road team that has not closed a game since early July.
The spread ladder starts tight. Portland -1.5 prices at 51c on both Kalshi and Polymarket, and Seattle -1.5 sits at 45c, which is the same near coin-flip read the moneyline gives. From there the ladder falls off fast: Portland -3.5 at 44c, Portland -6.5 at 34c, Portland -9.5 at 25c and Portland -12.5 at 17c. DraftKings has the number at POR -1.5, so the exchanges and the sportsbook agree on the shape.
The total is the more opinionated market. Kalshi's ladder puts the over 177.5 at 60c, over 180.5 at 52c and over 183.5 at 43c, which places the true pivot at roughly 181 points. Polymarket's two total lines agree, with over/under 181.5 at 49c and over/under 182.5 at 45c, and DraftKings posts 181.5. Given Portland has cleared 97 points three times in its last six and Seattle has scored at least 83 in each of its last four, the number is defensible rather than cheap. The first-half market carries a 93.5-point total at 51c and a Portland first-half spread of over 4.5 points at 41c.
Polymarket also lists 18 player props on this game, including Dominique Malonga points at 17.5 and rebounds at 8.5, Carla Leite points at 17.5 and assists at 7.5, and Natisha Hiedeman points at 16.5. Those are the only prop markets on this board, so the Kalshi side of the page is moneyline, spread and total only.
Every contract on this board settles off the final score of the August 8, 2026 game at Moda Center. The moneyline pays the winner, the spread settles against the final margin, and the total settles against combined points including any overtime. Both exchanges settle within hours of the final whistle.
Road split: Seattle is 2-16 away from home against Portland's 7-9 mark at Moda Center.
Malonga workload: Dominique Malonga at 16.9 points, 8.7 rebounds and 1.3 blocks per game is the single biggest swing factor for the Storm.
Leite usage: Carla Leite at 15.9 points and 6.4 assists per game drives the Portland -1.5 price at 51c.
Cross-platform gap: Kalshi's Seattle contract implies the Fire at 53c while Polymarket prices Portland at 56c.
Total pivot: the 180.5 line at 52c on the over sits just under the DraftKings number of 181.5.
The other WNBA game on the same slate is Indiana Fever vs Chicago Sky, where the total is set roughly 11 points higher than this one. Portland's previous outing, the Toronto Tempo vs Portland Fire board, is the best reference point for how this market prices an expansion team at home. Season-long markets for both clubs, plus every other game on the schedule, are on the WNBA hub.
The moneyline resolves to the team that wins the game at Moda Center in Portland on August 8, 2026, with tip scheduled for 8:30 PM ET. Each winning contract pays $1 per share and the losing side settles at $0. WNBA games cannot end in a tie, so any overtime counts toward the final score for every market on this board. Spread contracts settle against the final margin, meaning Portland -1.5 pays if the Fire win by 2 or more points, and total contracts settle against combined points including overtime. First-half markets settle on the halftime score only. If the game is postponed and played on a later date, Kalshi and Polymarket settle on the completed game once it is played; if it is canceled outright and not made up, both platforms void the market and refund per their own house rules.
As of August 8, 2026, the Portland Fire trade at 56c on Polymarket and the Seattle Storm at 46c across both books (47c on Kalshi, 45c on Polymarket). That is roughly a 56% implied win probability for the home side.
Portland is the favorite. The Fire are 12-19 and 7-9 at home, while Seattle is 6-27 and 2-16 on the road with 10 straight losses. DraftKings also has Portland laying 1.5 points.
Both Kalshi and Polymarket. Kalshi carries the moneyline plus full spread and total ladders with $3.2K of moneyline volume; Polymarket carries the moneyline, two total lines and 18 player props with $426 of moneyline volume.
Portland -1.5 prices at 51c on both exchanges and Seattle -1.5 at 45c. The total pivots at 180.5 points with the over at 52c on Kalshi, against a Polymarket line of 181.5 at 49c and a DraftKings number of 181.5.
Whether the Fire price holds above 55c into tip on August 8, 2026, and whether the 3c gap between the Kalshi and Polymarket versions of the Portland side closes. Dominique Malonga's availability is the largest single input on the Seattle number.
