Kalshi's most traded NFL Week 1 market is Cowboys at Giants
Kalshi's most traded NFL Week 1 market is Dallas Cowboys at New York Giants. Kalshi traders price the Philadelphia Eagles at 68-70% to beat the Washington Commanders, with the line moving after left tackle Laremy Tunsil was ruled out for the season. Kalshi and Polymarket both list the Buffalo Bills vs. Houston Texans matchup as the tightest Week 1 game. The markets opened alongside player prop coverage running on multiple platforms.
NFL Week 1 pricing on Kalshi is now thick enough to show real injury-driven movement, which matters for trader confidence. The Eagles line shifted after Tunsil's injury, proving the market absorbs new information rather than sitting static. That responsiveness is what separates a functional venue from a promotional one. Dallas-New York carrying the highest flow on Kalshi suggests traders treat the Sunday night spotlight as the liquidity anchor.
The Bills-Texas tightness on both Kalshi and Polymarket means two registered venues now price the same contest within a narrow band, so traders can comparison-shop for fills. Kalshi's real test comes when Monday's order book complexity under live flow. A slippage gap in a featured game would push size toward wherever depth proves sharper that night.
