Montreal is the 86c favorite and Ottawa the 14c underdog on a Kalshi-only board carrying about $12.6K in lifetime volume. The Alouettes are 8-1 with 16 points and sit eight clear of Toronto in the East; the Redblacks are 0-9 with zero points and have lost 15 straight dating to last season. Kickoff is 7:30 p.m. ET Thursday at Percival Molson Memorial Stadium. The live board above carries the current moneyline, the five-rung spread ladder and the totals.
The Redblacks vs Alouettes board is the widest price separation on this CFL slate, and the records behind it are not close. Montreal is 8-1 with 16 points and a 5-0 division record, eight points clear of Toronto in the East. Ottawa is 0-9 with zero points and has now lost 15 consecutive games dating back to the end of last season, the longest active streak in the modern CFL. Kickoff is 7:30 p.m. ET Thursday, August 20, 2026 at Percival Molson Memorial Stadium in Montreal, on TSN, RDS and CBS Sports Network.
One book, not two. This board trades on Kalshi only. The moneyline pair, all ten spread rungs and all five totals rungs carry a Kalshi price with no Polymarket counterpart, so there is no cross-platform read to make here and none should be inferred. Every cent on this page is a Kalshi price. Lifetime volume across the full board is roughly $12.6K, with the moneyline pair at about $2.8K and the spread ladder carrying most of the rest.
The 86c moneyline is not an artifact of a thin book. Montreal has scored 321 points in nine games (35.7 per game) and allowed 247 (27.4). Ottawa has scored 207 (23.0) and allowed 322 (35.8), per the CFL.ca standings. That is roughly a 21-point per-game differential before home field is added. The spread ladder prices Montreal -13.5 at 51c, the rung closest to a coin flip and the one carrying the most lifetime volume at about $5.0K, which matches the 13.5-point consensus number in TSN's game preview. Montreal -7.5 trades 65c, Montreal -3.5 trades 77c, and Montreal -20.5 trades 34c. The board is therefore pricing a comfortable Montreal win that stops well short of the raw scoring gap, and that restraint is defensible: Ottawa's differential is inflated by two blowouts (40-17 at Edmonton on July 9, 42-20 at Saskatchewan on August 7) while its other losses have been genuinely tight.
The underdog case is specific rather than sentimental. Ottawa played Montreal at this same stadium on June 28 and lost 37-35. On July 19 it lost to Winnipeg 36-34 in four overtimes. Jake Maier, named the starter out of camp, completed 28 of 43 for 314 yards with two touchdowns and one interception in last week's 33-21 loss at Winnipeg. The 14c price implies about a one-in-seven chance, and the route to it is the June 28 script: Maier near 65% completion, Ottawa inside one possession entering the fourth quarter, and Montreal's red-zone trips ending in field goals. What the price is saying is that this exact script has produced zero wins in fifteen attempts.
Montreal's side of the ledger is cleaner. Davis Alexander is 19-1 as a regular-season starter and is on pace for 6,280 passing yards with 36 touchdowns against 4 interceptions, which would be the second-highest single-season passing total in league history. Montreal comes off a bye and gets four defensive starters back in Mustafa Johnson, Geoffrey Cantin-Arku, Najee Murray and Wesley Sutton. Ottawa is on a short week after playing Friday and carries a league-high 17 players on the six-game injured list. Rest and health both sit on the favorite's side, which is the argument for the -13.5 rung over the flat moneyline at 86c.
The total is the least settled part of the board. Over 61.5 trades 54c, the only totals rung near even money, with Over 54.5 at 72c and Over 68.5 at 37c. Montreal allows 27.4 points per game and Ottawa allows 35.8, a sum of 63.2 that sits just above the 61.5 line. The two Montreal-Ottawa meetings this season bracket it almost exactly: 72 combined points on June 28 and 47 on July 31. The live risk to the over is a Montreal lead large enough to turn the fourth quarter into a run-clock exercise, which is precisely what happened in the 34-13 result on July 31.
Line movement has been minimal since the board opened. Montreal's moneyline started the snapshot window at 87c and sits at 86c, Ottawa has held flat at 14c, and Montreal -13.5 moved a single cent from 50c to 51c. Over 61.5 has not moved off 54c. A board this one-sided that refuses to drift is a board where the price has already absorbed both records, so the tradeable question is the margin and the total, not the winner.
One sourcing note worth stating plainly: ESPN does not carry a usable CFL feed, so no record, standing or roster fact on this page came from it. The records, points for and points against come from the CFL.ca standings; the kickoff time, venue, injury list and lineup notes come from club and league coverage; the prices come from the Kalshi board above.
The Redblacks vs Alouettes moneyline resolves to the team that wins the game at Percival Molson Memorial Stadium on Thursday, August 20, 2026, with a scheduled 7:30 p.m. ET kickoff. The spread rungs settle on the final margin (Montreal -13.5 pays if Montreal wins by 14 or more) and the totals rungs settle on combined final points (Over 61.5 pays at 62 or more). CFL overtime counts toward the final score, so a game decided in overtime settles the moneyline, the spread and the total on the post-overtime scoreline. Kalshi settles once the league posts the final result, typically within hours of the whistle.
Margin, not winner: Montreal -13.5 at 51c is the only genuinely two-sided rung on the board, and it carries the heaviest volume at about $5.0K.
Jake Maier's efficiency: 28 of 43 for 314 yards and two touchdowns last week is the profile that kept the June 28 meeting at 37-35 in this same building.
Montreal's bye-week health: four defensive starters return (Mustafa Johnson, Geoffrey Cantin-Arku, Najee Murray, Wesley Sutton) against an Ottawa roster with a league-high 17 on the six-game injured list.
Short week for Ottawa: the Redblacks played Friday and travel to a rested opponent, which is the single clearest argument for the larger spread rungs.
Total at 61.5: the combined 63.2 points-per-game defensive allowance supports the over at 54c, but a Montreal blowout flips the fourth quarter to run-clock and takes it away.
One-book pricing: with no Polymarket side, the 86c and 14c quotes rest on a single order book, so thin-book moves carry more weight than they would on a two-platform market.
Montreal's win total and playoff seeding feed straight into the CFL Grey Cup 2026 champion market, where the Alouettes' 8-1 start is already priced. Team-level boards for both sides live at the Montreal Alouettes hub and the Ottawa Redblacks hub. Ottawa's most recent result, the 33-21 loss that pushed the streak to 15, is on the Redblacks at Blue Bombers board. The full slate of games and futures sits on the CFL prediction markets hub.
Resolves to the team that wins the Ottawa Redblacks at Montreal Alouettes game at Percival Molson Memorial Stadium on Thursday, August 20, 2026, kickoff scheduled for 7:30 p.m. ET. The moneyline contract pays $1 per share to the winning team and $0 to the loser. Spread contracts settle on the final margin (Montreal -13.5 pays if Montreal wins by 14 points or more) and totals contracts settle on combined final points (Over 61.5 pays at 62 combined points or more). CFL overtime is included in the final score for all three market types. Kalshi is the only platform quoting this game, and it settles once the CFL posts the official final. If the game is postponed past the scheduled date, cancelled or abandoned before it is official, the contracts settle per Kalshi's published game-market rules for that series.
As of the evening of August 19, 2026, Montreal is 86c and Ottawa is 14c on Kalshi, implying about an 86% chance the Alouettes win. The spread sits at Montreal -13.5 (51c) and the main total is Over 61.5 at 54c.
Kalshi only. Polymarket does not carry a quote on either side of this game, so there is no cross-platform price to compare and every cent shown is a single-book Kalshi price. Lifetime volume across the full board is about $12.6K.
Montreal is favored at 86c, roughly an 86% implied probability. The Alouettes are 8-1 with 321 points scored and 247 allowed; the Redblacks are 0-9 with 207 scored and 322 allowed, and have lost 15 straight games dating to last season.
It resolves on the final score of the Thursday, August 20, 2026 game at Percival Molson Memorial Stadium, kickoff 7:30 p.m. ET. Kalshi settles the moneyline, spread and total once the CFL posts the official final, with overtime included.
Watch the Montreal -13.5 rung rather than the moneyline, since 51c is the only genuinely two-sided price on the board. Ottawa's injury report matters most: the Redblacks carry a league-high 17 players on the six-game injured list on a short week against a rested Montreal team coming off a bye.
