Calgary is the 58.5c consensus favorite at home in CFL Week 13, and the Stampeders are starting a quarterback who has never started a CFL game. Josh Love draws his first career start with Vernon Adams Jr. unavailable, and the board has not repriced for it: Calgary sits at 58c on Kalshi and 59c on Polymarket on the morning of August 29, 2026, with Hamilton at 43c and 42c. Both clubs carry 8 points, Calgary at 4-6 and fifth in the West Division, Hamilton at 4-7 and third in the East, and the game trades roughly $46.8K in lifetime volume across the two books.
Calgary is the shorter price in a game between two four-win teams, and the reason is location rather than form. The Stampeders host at 58c on Kalshi and 59c on Polymarket, which is a market that is not much more than a coin flip with a home tilt. Hamilton at 43c and 42c is priced as a live underdog, not a write-off. The live board above carries the current cross-platform quotes; the numbers cited on this page are the state of the market on the morning of August 29, 2026.
Per the league standings at cfl.ca, Calgary is 4-6 through 10 games with 8 points, fifth in the West Division. The Stampeders have scored 378 points, the most in their division, and allowed 327. The split that matters for a home favorite is that Calgary is 1-4 at home and 3-2 on the road. Their last game was a 30-26 loss to BC on August 13 in Week 11, and they have been idle since through a Week 12 bye, so this is a team taking the field for the first time in over two weeks.
Hamilton is 4-7 through 11 games, also on 8 points, third in the East Division behind Montreal (9-2) and Toronto (5-5). The Tiger-Cats have scored 257 points and allowed 319, a differential of minus 62, and only winless Ottawa (223) has scored fewer across the league. Hamilton is 3-3 at home and 1-4 away, which is the record that a road number at 43c has to account for. Their most recent result was a 39-20 loss at Toronto on August 22 in Week 12, listed on the cfl.ca schedule.
The quarterback situation is the story the price is not fully telling. The Stampeders' own practice report has Josh Love speaking to media ahead of what it describes as his first career CFL start against the Tiger-Cats, with Vernon Adams Jr. unavailable. Veteran kicker Rene Paredes returns for his 2026 season debut in the same game, which matters more than usual in a market where the main margin rung sits at Calgary by 7 or more. On the Hamilton side, the Tiger-Cats have not published a change at quarterback, and Tre Ford took the club's media availability during the week; Hamilton also added receiver Hakeem Harris and quarterback Cameron Peters on August 25. Anything beyond that on Hamilton's depth chart is not confirmed by a current source, so this page does not assert it.
These teams already met this season. The August 1 meeting in Hamilton settled to Calgary, with the Stampeders' contract closing at 99c on Kalshi and 100c on Polymarket. That is one data point in a season where Calgary has been better on the road than at home.
The board holds 459 price captures for August 29 across its Kalshi and Polymarket legs, running from roughly 00:01 to 14:53 UTC. That is a real window, and inside it the moneyline did not move. Kalshi's Calgary contract opened the window at 58c and sat at 58c across all 13 captures, with no tick off that number. Kalshi's Hamilton side drifted from 42c to 43c. Polymarket lists this game as a single binary and has held Hamilton at 42c through every one of its six captures, which implies Calgary at 58c on that book as well. A 1c cross-platform difference on the moneyline is inside normal spread and is not a pricing disagreement worth acting on.
The margin market is where money actually moved. The rung for Hamilton to win by 7 or more went from 17c to 23c over 102 captures, a 6c climb, while Calgary by 7.5 or more slipped from 29c to 28c. Calgary at minus 6.5 traded a 28c to 35c range across 158 captures before settling back at 33c, which is the number to use: that rung carries $8.3K in lifetime Kalshi volume and $1.8K in the last 24 hours. Polymarket does have a leg on that same rung, but it has traded $1.79 in 24 hours against Kalshi's $1.8K, so its 45c quote is a thin-book midpoint rather than a traded price and should not be read as a cross-platform signal. The rungs below Hamilton at minus 6.5 are similarly illiquid and do not price in a consistent ladder, so treat them as quotes rather than a margin read.
Put together, the day's action tightened the expected margin without touching the expected winner. The market still makes Calgary the favorite by roughly 16c of implied probability while paying more than it did last night for Hamilton to lose close or win outright.
Kickoff is Saturday afternoon in Calgary, per the Stampeders' own practice report. Neither the cfl.ca schedule nor the club schedule page published a clock time we could confirm, and the Kalshi ticker for this game (KXCFLGAME-26AUG29HAMCGY) carries a date with no time segment, so this page does not print one. Note that our ESPN feed does not cover the CFL, so every record, result and roster fact above comes from cfl.ca, ticats.ca or stampeders.com rather than a scoreboard API.
The moneyline resolves to the team that wins the game on August 29, 2026. Each winning contract pays $1 per share and the losing side pays $0. The spread rungs settle on the final score against the stated number, and because every listed rung uses a half point, no spread rung can push. The board settles on Kalshi and Polymarket once the game is final on its scheduled date. If the game is postponed or canceled, each platform applies its own void or extension rules rather than settling to a result.
Josh Love's first career CFL start: Calgary is a 58c favorite behind a quarterback who has never started a game at this level, with Vernon Adams Jr. unavailable.
Calgary's home split: the Stampeders are 1-4 at home and 3-2 on the road, which cuts directly against the reason they are favored here.
Sixteen days of rest: Calgary has not played since a 30-26 loss to BC on August 13 and comes out of a Week 12 bye, while Hamilton is on a normal week after a 39-20 loss at Toronto.
The margin market drifted toward Hamilton: the Hamilton by 7 or more rung climbed from 17c to 23c today while Calgary by 7.5 or more slipped from 29c to 28c.
Rene Paredes returning to the Calgary kicking game: the veteran makes his 2026 debut in a game whose primary spread rung sits at 6.5 points.
Eight points apiece with playoff position live: Calgary is fifth in the West behind BC at 10 points, Hamilton is third in the East behind Toronto at 10 points, and both need this one.
Both clubs are still priced in the Grey Cup 2026 championship market, which is where a four-win team's remaining season value actually shows up. For a game-by-game view of each side, the Calgary Stampeders hub and the Hamilton Tiger-Cats hub carry every board those teams trade on. Their most recent games are also live: BC at Calgary on August 13 and Hamilton at Toronto on August 22. The full slate sits on the CFL prediction market hub.
The moneyline resolves to the team that wins the Hamilton Tiger-Cats at Calgary Stampeders game on August 29, 2026, with the winning team's contract paying $1 per share and the losing team's contract paying $0. The spread rungs settle against the final score at the stated number, and because every listed rung is a half point (Calgary minus 3.5, minus 6.5, minus 7.5, minus 13.5, minus 20.5 and the matching Hamilton rungs), no spread contract can push. Kalshi settles under its KXCFLGAME and KXCFLSPREAD series and Polymarket settles its single game binary, both once the result is final on the scheduled date. If the game is postponed past the scheduled date or canceled outright, each platform applies its own void or extension rules rather than settling to a result.
On the morning of August 29, 2026, Calgary is 58c on Kalshi and 59c on Polymarket, a 58.5c average, and Hamilton is 43c on Kalshi and 42c on Polymarket. The board trades roughly $46.8K in lifetime volume across both platforms.
Calgary is favored at 58.5c, an implied win probability of about 58%, against Hamilton at roughly 43%. The primary spread rung has Calgary by 6.5 or more at 33c on Kalshi.
Both Kalshi and Polymarket list this game. Kalshi carries the moneyline under KXCFLGAME-26AUG29HAMCGY plus a full spread ladder under KXCFLSPREAD, and Polymarket lists a single game binary. Kalshi holds the large majority of the volume on every rung.
Josh Love makes his first career CFL start, per the Stampeders' own practice report, with Vernon Adams Jr. unavailable. Kicker Rene Paredes also returns for his 2026 season debut. Hamilton has not announced a change at quarterback.
It resolves when the game goes final on August 29, 2026, a Saturday afternoon kickoff in Calgary. Watch the spread rungs rather than the moneyline before then: the moneyline has not moved all day while Hamilton by 7 or more has climbed from 17c to 23c.
