All new users who enter the Polymarket promo code ACTION at signup deposit $10 and receive a $25 trading bonus right away, no rollover and no extra steps required. The timing lines up well: Thursday Night Football takes us to the altitude for Seahawks vs. Broncos at 8:15 p.m. ET on Prime Video, giving new accounts a full slate of markets to explore before the opening possession.
Both teams enter Week 6 at 3-2. Seattle sits second in the NFC West behind an unbeaten San Francisco club, and the Seahawks bring the league’s No. 1 defense by yards per play allowed into Denver. The Broncos sit level with Las Vegas in the AFC West and still chase an undefeated Kansas City team atop the division. Seahawks vs. Broncos carries extra weight because the two sides have not met since September 2024, when Seattle won 26-20 at Lumen Field. Denver still leads the all-time series 35-23, but Seattle has won the last two meetings, and this marks the first time the rivalry returns to Mile High since 2018.
That history gives this Thursday night plenty of storylines, and it pairs naturally with the Polymarket promo code ACTION offer. Readers who want to put research behind a position, rather than just watch, get $25 in credit to test the matchup markets before the preview section below even gets into the pick.

Seahawks vs. Broncos Preview
Seattle’s defense creates the biggest edge in this matchup. The unit ranks No. 1 in yards per play allowed and No. 2 in EPA per play, and it faces a Denver offense still searching for consistency even after Sean Payton took over play-calling duties in Week 5. Bo Nix is far more efficient at home than on the road, which keeps Denver competitive, but Seattle’s pressure package has given young quarterbacks problems all season. The short week compounds Denver’s challenge further, since the Broncos must prepare without Pat Surtain II or Talanoa Hufanga in the secondary.
Seattle’s offense carries some risk after a Week 5 loss to San Francisco, and Sam Darnold has struggled since returning from a glute injury. Still, the Seahawks have historically bounced back well off losses, and the thin air at Mile High tends to bother visiting offenses less than it bothers a short-rested home team trying to install new wrinkles. Denver’s run defense has also shown cracks, which helps Seattle on early downs even with a limited ground game. The total sitting at 40.5 suggests books expect a tighter, defense-driven game rather than a shootout.
This pick lands on the Seahawks covering -2.5. Seattle’s defensive floor, Denver's short-week disadvantage with a banged-up secondary, and Seattle’s recent dominance in this series all point to the Seahawks controlling the pace and finishing comfortably ahead. The spread sits lower than it probably should given the defensive talent gap, which adds value to taking Seattle at -2.5 rather than waiting for the number to move further.
Seahawks vs. Broncos Prediction: Seahawks -2.5
