NFL Preseason Week 1 Odds on Saturday, August 15
Prediction markets price each team in cents. A team at 55% costs roughly 55 cents per contract, and each winning contract pays out $1. Read those percentages the same way you read NFL odds at a sportsbook.
Here are Saturday's seven matchups:
- Vikings (55%) vs. Giants (45%)
- Browns (62%) vs. Bears (38%)
- Panthers (41%) vs. Bills (59%)
- Jaguars (45%) vs. Saints (55%)
- Rams (45%) vs. Chiefs (55%)
- Eagles (63%) vs. Ravens (37%)
- Cowboys (41%) vs. Seahawks (59%)
Prices move fast in August because coaches release depth charts hours before kickoff. Check the app before you lock in a position.
Regular season NFL Week 1 odds already sit on the board, too, alongside NFL futures markets on division winners, season win totals, and the Super Bowl LXI champion.
NFL Preseason Week 1 Picks
Our analysts break down three of Saturday's games below. Each pick leans on rotation news, quarterback snap counts, and the market price at the time of writing.
Browns vs. Bears Prediction: Bears +3.5 (53%): The Bears have more certainty with Bagent and veteran backup Keenum, while Johnson remains unbeaten this preseason. Cleveland has greater uncertainty at quarterback, along the offensive line, and with a first-time head coach, making Chicago and the points the safer play.
Rams vs. Chiefs Prediction: Chiefs 1st Half ML (27%): The Chiefs have struggled in recent preseasons but have averaged 23.5 points per game and have improved depth at running back, receiver, and defense. With experienced quarterbacks likely giving way to volatile rookies, the best value is Kansas City in the first half.
Cowboys vs. Seahawks Prediction: Cowboys +2.5 (50%): The Cowboys enter the preseason in a strong offensive position, while their first-round picks Caleb Downs and Malachi Lawrence should help limit Drew Lock early. Short road underdogs have also been highly profitable in the preseason, covering 66.4% over the past decade, making Dallas an appealing play.

Why Prediction Markets Cover More States Than Sportsbooks
Federal commodities rules govern these platforms rather than state gaming law. That distinction matters for anyone asking where sports betting stays legal.
California, Texas, and Georgia all block traditional sportsbooks, yet residents in those states trade NFL contracts today. Polymarket, Kalshi, and DraftKings Predictions each operate there.
