Calgary is the road chalk at 69c on both books, and the market walked there in a straight line: the Stampeders opened the July 31 session at 66c on Kalshi and stepped through 67c and 68c to 69c by evening while Hamilton slid from 35c to 31c. Both teams carry 3-4 records into Week 9 at Tim Hortons Field, but the point differentials do not agree. Calgary has scored 278 points in seven games and Hamilton has scored 167. The live board above carries the current Kalshi and Polymarket prices plus the full spread ladder.
Calgary opens a three-game road trip as a 69c favorite in Hamilton, the widest price either side has held on this board. Both teams sit at 3-4 and both are chasing .500, but the market is not treating them as equals. Calgary has scored 278 points in seven games, a league-high 39.7 per game, while Hamilton has scored 167 and allowed 190. The gap in the numbers is the gap in the price.
Calgary arrives off a 52-30 win in Winnipeg on July 24, a game that produced three separate record lines. Vernon Adams Jr. pushed his season to 20 touchdown passes with zero interceptions, the most touchdowns to open a CFL season without a pick. Defensive back Ben Labrosse tied the franchise single-game record with three interceptions. Running back Tyreik McAllister became the first player in league history to score a rushing, receiving and return touchdown in the same game, and he did it inside one half. Adams Jr. starts again here, and that clean touchdown-to-interception ledger is the single largest input into the 69c price.
Hamilton is moving the other way. The Tiger-Cats lost 31-18 to Montreal in Week 8 and hand the ball to Tre Ford for his third start of the season with Bo Levi Mitchell injured. Ford has thrown two touchdowns and two interceptions across his first two starts. Montreal sits at 6-1 atop the East, so Hamilton at 3-4 is playing from behind in its own division while drawing a West opponent that just hung 52 on the defending-standard Winnipeg defense. Calgary also swept the 2025 season series with Hamilton 2-0.
The moneyline itself is a clean two-way market: Calgary 69c on Kalshi and 69c on Polymarket, Hamilton 31c on Kalshi and 32c on Polymarket. Kalshi's pair sums to exactly 100, so 69c reads as a straight 69% implied probability rather than a vig-inflated one. Polymarket's pair sums to 101, which means a Hamilton buyer pays 1c more there for the identical contract. Kalshi is the better price on the underdog and the two books are dead level on the favorite.
Liquidity is one-sided. Kalshi carries roughly $1.3K on the Calgary leg and $1.1K on Hamilton against $20 a side on Polymarket, and the board's total volume is about $1.9K. Read the Polymarket quotes as a mirror of Kalshi, not as an independent second opinion.
Kalshi runs the deeper alt ladder. Calgary is 55c at -3.5, 44c at -6.5, 43c at -7.5, 28c at -13.5 and 17c at -20.5. The Hamilton side of the ladder pays 33c at -3.5, 26c at -6.5 and 22c at -7.5. Polymarket posts a single spread contract, Calgary -2.5 at 61c, which is a shorter number than anything Kalshi offers and therefore not directly comparable.
That ladder brackets the sportsbook consensus of Calgary -4.5. At -3.5 the market pays 55c and at -6.5 it pays 44c, so the implied fair number sits around 5 points, in line with the book number rather than richer than it. The -13.5 rung at 28c is the more interesting entry: the market is assigning better than a one-in-four chance to a two-touchdown Calgary win, which is the price of believing the Winnipeg result was a signal instead of a spike.
The total is Polymarket only. There is no Kalshi total on this game, and the single line is 64.5 with the Over at 38c on the board, easing into the low 30s across the July 31 snapshot series. That is a real disagreement with Calgary's form, since the Stampeders have gone over the posted total in all seven of their games and average 39.7 points. Hamilton's 23.9 points per game is what holds the number down, and the Hamilton forecast as of July 31 carried a 70% chance of scattered showers at kickoff with temperatures near 25C, which pushes the same direction.
The movement is uniform and it favors Calgary. On Kalshi the moneyline opened the July 31 session at 66c and printed 67c, 68c and 69c through the day, with Hamilton falling 35c to 31c on the other side. Polymarket tracked from 68c to 69c. The spread moved harder than the moneyline: Calgary -6.5 went from 38c to 44c across the same window, a 6c firming, which says incoming money is not simply backing Calgary to win but backing Calgary to win comfortably. Nothing on this board moved toward Hamilton.
The moneyline settles on the winner of the game at Tim Hortons Field in Hamilton on Saturday, August 1, 2026, with a 3:00 p.m. ET kickoff. Spread contracts settle on the final margin and the 64.5 total settles Over if the two teams combine for 65 or more points. Overtime counts toward the official final score for all three market types. Both Kalshi and Polymarket close the contracts once the CFL final is official, which is typically within a few hours of the final whistle.
Vernon Adams Jr.'s interception count: 20 touchdowns and zero picks through seven games is the record start driving Calgary to 69c, and the first turnover is the most likely single trigger for the price to come back.
Tre Ford's third start: Hamilton's fill-in for the injured Bo Levi Mitchell has two touchdowns against two interceptions, and the 31c underdog price is largely a quarterback price.
The spread firming faster than the moneyline: Calgary -6.5 moved 38c to 44c on July 31 while the moneyline moved 3c, a divergence that points at margin bets rather than side bets.
The Polymarket-only total: 64.5 with the Over at 38c is priced against a Calgary team averaging 39.7 points, and there is no Kalshi total to arbitrate it.
Weather at Tim Hortons Field: a 70% chance of scattered showers as of the July 31 forecast is the standing argument for the Under and against Calgary's ladder rungs above -13.5.
Division stakes: Hamilton is 3-4 behind a 6-1 Montreal team in the East, so this is a game the Tiger-Cats need more than the standings suggest.
Calgary's Week 8 board in Winnipeg is the 52-30 game that reset this price, and Hamilton's Week 8 board against Montreal is the loss that cut the other way. The season-long read trades on the 2026 Grey Cup champion market, where both of these teams are priced against the 6-1 leaders. Full schedules, standings context and every posted line live on the Calgary Stampeders hub and the Hamilton Tiger-Cats hub, and the rest of the Week 9 slate is on the CFL league page.
The moneyline resolves to the team that wins the Calgary Stampeders at Hamilton Tiger-Cats game at Tim Hortons Field on Saturday, August 1, 2026, with each winning contract paying $1 per share and the losing side settling at $0. Spread contracts settle on the final margin, so Calgary -3.5 pays only if Calgary wins by 4 or more points, and Hamilton -3.5 pays only if Hamilton wins by 4 or more. The 64.5 total on Polymarket settles Over if the two teams combine for 65 or more points and Under at 64 or fewer. Overtime counts toward the official final score for every market type on this board. If the game is postponed, both Kalshi and Polymarket carry the contracts to the rescheduled date; if it is canceled outright, each platform voids and refunds under its own rules. Settlement follows the official CFL final score once the platforms mark the event closed, typically within a few hours of the final whistle.
As of August 1, 2026, Calgary is the 69c favorite on both Kalshi and Polymarket. Hamilton trades at 31c on Kalshi and 32c on Polymarket, an implied win probability of roughly 31%.
Calgary, at 69c on both books, which is a 69% implied probability. The Stampeders are favored on the road despite a 3-4 record because they average a league-high 39.7 points per game against Hamilton's 23.9.
Kalshi prices Calgary -3.5 at 55c and Calgary -6.5 at 44c, while Polymarket posts a single Calgary -2.5 at 61c. The only total is Polymarket's 64.5, with the Over at 38c as of August 1, 2026.
Kalshi and Polymarket both list the game. Kalshi holds nearly all of the roughly $1.9K on this board and is the only platform with a full spread ladder, so it is the better venue for anything beyond a straight moneyline.
On Saturday, August 1, 2026, once the game at Tim Hortons Field in Hamilton goes final. Kickoff is 3:00 p.m. ET and both platforms settle on the official CFL final score, including overtime.
Whether Vernon Adams Jr. throws his first interception of the season, how Tre Ford handles his third start, and whether the Calgary -6.5 spread keeps firming past 44c after moving 6c on July 31.
