New traders who register before kickoff lock in a $50 Polymarket sign-up bonus with a first deposit of just $10. Enter the Polymarket promo code ACTION during registration, fund the account, and start the night with $60 in bonus funds to trade with instead of $10.
Monday Night Football sends us to La La Land for the Giants vs. Rams matchup at 8:15 p.m. ET on ABC/ESPN. It was a tale of two cities for each squad, with one team repping opposite sides of the country: the Giants steamrolled the Cowboys in Week 1, while the Rams got steamrolled down under in Australia. The teams may have played only one game, but injuries are piling up: Myles Garrett went to the IR list, and Puka Nacua is questionable tonight.
The math does the talking here. A $10 deposit returns a $50 credit, a 500% match that stands among the strongest welcome offers in the prediction market space right now. Polymarket applies the sign-up bonus automatically once the qualifying deposit settles, so no first trade needs to grade before the credit appears in the balance.
Two other features deserve a look once you're set up. Polymarket Squads put you in a group setting where you chat with other members, tail their trades, and talk through strategy together. The new Polymarket 15-minute Bitcoin up/down markets move even faster, giving you a way to jump into the action on a quarter-hour clock.

Where the Polymarket Sign Up Bonus Works
Polymarket US operates as a CFTC-regulated designated contract market, which puts it under federal oversight rather than state-by-state gaming licenses. The company's own app listing claims availability everywhere except Nevada, including big non-betting states like California, Texas and Georgia. Several states continue to challenge prediction markets in court, so eligibility shifts, and the app confirms your status in under a minute during signup.

Nobody had the Giants opening 1-0. John Harbaugh's debut produced a 28-20 win over Dallas, with Jaxson Dart throwing for 230 yards and three touchdowns. Cam Skattebo helped by grinding out 81 rushing yards and a touchdown on 18 carries. New York controlled the ball for more than 36 minutes and held Dak Prescott to 175 passing yards.
The Rams took the opposite path, flying out to Melbourne on little rest, losing 27-7 to San Francisco, and watched Matthew Stafford finish 15-of-25 for 155 yards with no scores and an interception. Myles Garrett then landed on injured reserve after knee surgery, stripping the defense of its best pass rusher even as Aaron Donald makes his season debut.
Back the road dog. The Rams surrendered 174 rushing yards in Week 1 at 5.8 yards per carry, and that profile plays directly into a Giants offense that just bullied Dallas at the line of scrimmage. Long New York drives shorten the game, reduce possessions, and keep a touchdown-plus number live deep into the fourth quarter.
Market pricing backs the read too. A +275 moneyline implies roughly a 27% shot outright, which undersells a healthier, more balanced Giants roster against a team missing its top defender.
- Giants vs. Rams Prediction: Giants +7
