New users who sign up with the Polymarket promo code ACTION unlock a straightforward welcome offer this week: deposit $10 and receive a $25 trading bonus. The credit lands in your account after your deposit clears, and you can put it to work on NFL Week 4 markets, including Sunday's Jaguars vs. Bengals AFC showdown at 1 p.m. ET on CBS. This welcome offer removes most of the friction from getting started, since the platform only asks for a $10 deposit to activate the full bonus.
Both teams enter at 2-1, and the game carries extra weight because it reunites quarterbacks Trevor Lawrence and Joe Burrow, who met in the College Football Playoff National Championship five years ago before becoming back-to-back No. 1 overall picks. It is also a rematch of last season's Week 2 game, where the Jags let a win slip away at the end, so I believe the revenge motivation will play a huge factor in how this one turns out.
Trading on a game with this much history attached makes the Polymarket promo code worth claiming before kickoff. Once your account reflects the $25 bonus, you can browse the Jaguars vs. Bengals markets and decide where you see the most value, and the rest of this preview breaks down the numbers that matter most.

States Where Polymarket is Available
Polymarket continues expanding its footprint across the country, and most states currently allow access to the platform. A handful of states still sit outside the current rollout, so confirm eligibility directly on Polymarket's site before you try to register, since state-level access can change from one week to the next. Checking first saves you from entering the Polymarket promo code only to find your state isn't cleared yet.

Jaguars vs. Bengals Preview
Cincinnati opened as a favorite of this size partly on reputation, but the underlying numbers tell a different story. Jacksonville ranks ahead of the Bengals in EPA per play and yards per play through three weeks, and the Jaguars defense has allowed far fewer points per game than Cincinnati's. The Bengals' two wins came against Tampa Bay and Houston, two teams that have struggled badly so far this season, which makes those results look less impressive in hindsight. Burrow and the Cincinnati offense also face a banged-up secondary of their own, with safety Kyle Dugger out and Bryan Cook questionable, issues that show up on the other side of the ball rather than the Jaguars' side.
Lawrence and the Jaguars offense arrive with real momentum after posting 82 points through three games while allowing only 36. That point differential ranks among the best in the league and suggests Jacksonville's 2-1 record undersells how the team has actually played. The Jaguars defense has also limited opponents to just 12 points per game on average, a number that should hold up well against a Cincinnati offense still finding its rhythm. Getting 2.5 points in a matchup this evenly played offers real value, especially with both quarterbacks carrying the kind of history that tends to produce a tight finish.
Everything points toward a close game decided in the final minutes, and the number favors the side getting points. The pick here lands on Jacksonville covering the spread and giving the Jaguars a real chance to win outright in Cincinnati.
