Cardinals at Rams is the most lopsided game on the Week 6 board: Rams at 87% on Kalshi, 87.5% on Polymarket US
DeFi Rate's Week 6 winner table, captured Oct. 13 at 11:46 AM ET, prices Arizona at just 14% on Kalshi and 12.8% on Polymarket US, the widest gap between favorite and…
The Los Angeles Rams have the strongest favorite pricing across the 14 NFL Week 6 matchups in DeFi Rate’s comparison, with their winner contract at 87% on Kalshi and 87.5% on Polymarket US. Arizona Cardinals contracts stand at 14% and 12.8%, respectively, making this the week’s most unevenly priced matchup.
According to DeFi Rate, the winner-market snapshot was taken on October 13 at 11:46 a.m. ET. The percentages represent purchase prices before fees, rather than guaranteed outcomes, and can move before kickoff.
Markets favor Los Angeles despite recent loss
The NFC West matchup is scheduled for Sunday, October 18, at 4:05 p.m. ET at SoFi Stadium, with FOX carrying the game. Both teams enter after defeats, but the markets assign Los Angeles a substantial advantage.
The Rams dropped to 2-3 following a 37-34 overtime loss to Buffalo on Monday, October 12. Arizona fell to 1-4 after losing 45-21 to Detroit, according to DeFi Rate. Los Angeles’ losing record has not prevented it from attracting the highest favorite price on the Week 6 board.
A different profile from the closer contests
DeFi Rate identifies Panthers-Eagles, Cowboys-Packers and Seahawks-Broncos among the week’s more competitive games, while the Rams, Kansas City Chiefs and San Francisco 49ers are substantial favorites. Green Bay’s Kalshi price rose from 48% in the article’s October 10 snapshot to 53% in the October 13 snapshot, reversing Dallas’ earlier advantage. Those observations compare article snapshots, not opening prices.
Los Angeles also remains prominent in the season-long market. According to DeFi Rate’s October 13 observation at 11:41 a.m. ET, the Rams’ Kalshi Super Bowl LXI price was 10.5%, behind San Francisco at 12.5% and Buffalo at 11.5%.
What it means for prediction markets
- The platforms broadly agree: Rams purchase prices of 87% on Kalshi and 87.5% on Polymarket US show little difference in how the two venues price the favorite.
- Purchase prices need careful interpretation: The quoted prices for both teams exceed 100% when combined on each platform. They are before-fee buy quotes, not a normalized probability distribution.
- The timestamp matters: These figures describe the October 13 snapshot, not necessarily prices available on October 14 or at kickoff.
- The contracts answer different questions: Los Angeles’ commanding Week 6 price and its 10.5% Super Bowl LXI price concern separate outcomes and should not be read interchangeably.
