MIN Vikings vs CHI Bears

The MIN Vikings vs CHI Bears market covers the Week 1 NFL matchup originally scheduled for September 20, with Polymarket and Kalshi resolving to the winning team (ties split the market 50/50), and Polymarket keeping the market open if the game is postponed until it is completed. The event is live and has drawn roughly $3.1M in combined volume, with Polymarket ($2.06M) and Kalshi ($1.06M) accounting for nearly all of it; Azuro carries a nominal $80 and a Polymarket US mirror shows no volume. On the moneyline, the Bears are the favourite. The cross-platform consensus sits at 66.8%, with Polymarket US at 67.0%, Polymarket at 66.0% and Kalshi at 66.0% — a tight 1.25-point spread. The Vikings price out symmetrically around the mid-30s, with a 34.5% consensus and platforms clustered between 33.5% and 34.0%. That gap implies the Bears are roughly a two-to-one favourite, consistent with a meaningful but not overwhelming edge. Across the broader set of derivative markets (spreads, totals, player props), most lines agree within a point or two between Polymarket, Polymarket US and Kalshi. The takeaway: platforms are closely aligned on a Bears-favoured game, with only minor pricing differences on the headline moneyline.
