What to Know About Polymarket Promo Code ACTION
Polymarket promo code ACTION is the code for you to enter during registration to lock-in the $50 welcome bonus. Deposit $10 to trigger $50, no trade required.
Prediction market apps like Polymarket price outcomes in cents rather than American odds. That differing structure changed how I spent my $50 bonus a week ago. Keep this information in mind while claiming Polymarket, which separates them traditional online sportsbooks:
- Every contract trades between 1¢ and 99¢, and a winning contract settles at $1. A Broncos share at 45¢ tonight returns 55¢ of profit.
- The price doubles as the implied probability, so I read a 45¢ Denver share as a 45% chance.
- Polymarket lets me exit a position at any point before the final whistle. A Denver lead in the third quarter turns into profit even if the Rams rally.
- My $50 bonus landed as tradable funds I spread across the whole board rather than one individual market.
- Polymarket carries enough liquidity that prime time NFL odds are tight, making it all the more important you keep an open eye to entering and exiting positions.

My Rams vs. Broncos Prediction
Both clubs sit at 1-1 after ugly openers and emphatic Week 2 rebounds. Matthew Stafford torched the Giants for 327 yards and four touchdowns, Davante Adams piled up 195 receiving yards, and Bo Nix answered with 288 yards on 31 attempts in a comeback over Jacksonville.
- Rams vs. broncos Prediction: Denver moneyline (46¢), with under 44.5 total points (50¢) as a secondary lean
Four factors push me toward the home underdog when making my NFL picks tonight:
- Los Angeles flies to altitude on a short week after playing on Monday night. Travrling and playing in altitude could make an impact on an older roster.
- Pat Surtain II and Riley Moss erase perimeter targets, and a hip issue has Puka Nacua doubtful to play. Adams will have little help and be blanketed Surtain.
- Denver has home field advantage behind them and come off a game where they held an explosive Jaguars offense to just 13 points.
- The under has cashed in all four combined games these teams have played, and I expect Sean Payton to lean on the run game against the Rams' pass rush.
