Brock Purdy and Josh Allen sit nearly even atop the 2026 NFL MVP market because both quarterbacks have delivered elite efficiency on undefeated or near-perfect teams through five weeks. Purdy’s 119.3 passer rating, 13 touchdowns, and two interceptions have powered the 5-0 49ers, while Allen’s dual-threat production—1,249 passing yards, seven touchdowns, plus 239 rushing yards and eight scores—has kept the 4-1 Bills competitive despite one loss. Patrick Mahomes trails at roughly 11% amid the Chiefs’ strong record but comparatively modest individual numbers. The narrow gap reflects trader consensus on early-season form, team success, and the historical value of late-draft standouts like Purdy versus proven dual-threat candidates like Allen, with the race poised to shift on upcoming results.
