Grey Cup Odds 2025: Blue Bombers New Favorites as Argonauts Tumble

The Toronto Argonauts opened the season as the Grey Cup odds favorites at our best sportsbooks in Canada, but two losses in their first two games have opened the door for the Winnipeg Blue Bombers.

Winnipeg handled business in its first game of the season against CFL Most Outstanding Player odds favorite Nathan Rourke as Mike O'Shea's team attempts to make a sixth straight Grey Cup. However, it won't be easy; the Montreal Alouettes, Saskatchewan Roughriders, and Calgary Stampeders are all off to impressive 2-0 starts.

🤖 Grey Cup AI prediction

For entertainment purposes, we asked ChatGPT, a popular large language model chatbot, to analyze historical trends and CFL stats before predicting the winner of this year's Grey Cup. Our AI prediction projects the Montreal Alouettes to win the Grey Cup.

🖥️ AI Grey Cup prediction: Montreal Alouettes 

🏈 Opening statement: The Alouettes kicked off the season with a decisive 28–10 win over the defending champions in Week 1 and followed it up by cruising to a 39-18 win over the Ottawa Redblacks on the road
🏈 Offensive efficiency: New QB Davis Alexander has looked sharp while showcasing his dual-threat ability and taking advantage of Montreal's loaded wide receiver group, including Canadian star Tyson Philpot
🏈 Defensive consistency: Montreal’s defense has been one of the CFL’s most reliable units dating back to last season, combining a strong pass rush with disciplined coverage that consistently limits big plays and forces turnovers

🤔 Betting takeaway: ChatGPT's AI prediction would mean the Alouettes (+500 via DraftKings) winning the Grey Cup. ChatGPT is a large language model and not specifically designed for predicting sporting events, so these projections should be viewed as entertainment or a supplementary data point for your CFL championship betting research.
