Josh Allen leads the 2026 NFL MVP market at 31% implied probability due to his top rankings in EPA per play, positively graded plays, and yards per attempt, alongside the Buffalo Bills' 5-1 record and his dual-threat production through six games. Brock Purdy sits at 17.7% on the strength of his 69% completion rate, 15 touchdowns, and efficiency despite San Francisco 49ers wide receiver injuries, though a recent loss has tempered his momentum. Joe Burrow's 16.4% reflects his league-leading PFF passing grade, 71.7% completion rate, and 15 touchdowns, fueled by a four-touchdown Week 7 outburst that lifted the Bengals to 4-2. Caleb Williams, Trevor Lawrence, and others trail as traders weigh supporting casts, recent form, and the historical quarterback tilt in MVP voting.
