NFL Betting Promos for Bucs vs. Cowboys: Top Sign-Up Bonus Offers for Thursday Night Football

NFL betting promos for Bucs vs. Cowboys are worth shopping around before tonight's Thursday Night Football kickoff at 8:15 p.m. ET on Prime Video. Dallas opened as a 10-point favorite over Tampa Bay, but that number has been bet down to 7.5-to-8.5 even as the public keeps hammering the Cowboys side, a split that often signals bigger money landed elsewhere.

On paper, this NFL matchup looks lopsided. Tampa Bay is 0-4 and turning to rookie quarterback Jalon Daniels for a second consecutive start with Baker Mayfield still out with a thumb injury, while Dallas sits at 2-2 and has made nearly every game a shootout. The total hovers near 47.5, with the Cowboys on a double-digit streak of games that clear the over.

Line movement aside, the Thursday-night game to kick off NFL Week 5 is as good a reason as any to set up a new sportsbook account before you place a bet. Signing up takes just a few minutes, and most of tonight's welcome offers fall into one of two categories: a single first-bet safety net or a bonus that pays out gradually over several days of betting.

NFL Betting Promos for Bucs vs. Cowboys: Thursday Night Football

NFL Betting Promos

1. Fanatics Sportsbook Promo Code ACTION26

Thursday night is just the start of a full NFL slate this week, and Fanatics' offer reflects that. Enter the Fanatics Sportsbook promo code ACTION26 and any losing bet of $1 or more at odds of -500 or shorter gets refunded as FanCash, capped at $100 a day. Rack it up over 10 straight days of qualifying action and the match tops out at $1,000.

That FanCash converts into bonus bets or Fanatics store credit, so even a wrong read on Cowboys-Bucs won't cost you heading into the weekend. Just know the streak requirement is strict—miss a day of qualifying bets and the count resets to zero.

2. BetMGM Bonus Code TOPACTION

For bettors who already have a number they like on the spread or the Over, BetMGM's offer protects one decisive swing. Deposit at least $10, bet at least $10 with the BetMGM bonus code TOPACTION on any Bucs-Cowboys market, and a loss comes back dollar-for-dollar as bonus bets, up to $1,500.

A win pays out normally, with no bonus triggered, so this offer suits a bettor willing to place a larger first wager rather than spread smaller bets around.

4. DraftKings Promo Code

Nothing on this list asks for less upfront than the DraftKings promo code. Drop $5 on any Bucs-Cowboys market, and DraftKings pays out $150 in bonus bets no matter how your wager lands; win or lose, you get paid.

One catch: the $150 arrives as six separate $25 tokens rather than one lump sum, and each token expires seven days after it's issued. Claim them all without letting any go to waste.

5. FanDuel Promo Code

The FanDuel promo code structure rewards bettors who plan to stay active past tonight. Place $5 on any market each day, and you'll earn a reset token worth $1-$50. If you lose that follow-up bet and the stake comes back, you can earn up to $50 daily over a five-day stretch.

Kick it off with Cowboys-Bucs, and you've effectively got a safety net running into Sunday's full Week 5 card, not just tonight's single game.

6. theScore Bet Promo Code ACTNEWS

Oddly, theScore Bet doesn't get mentioned as often as the bigger national apps, but the offer holds up fine next to them. Sign up with theScore Bet promo code ACTNEWS, place your opening wager on tonight's game, and a loss returns as a bonus bet while a win pays out normally.

The bet slip takes a beat longer to load than some competitors, but the pricing on mainline NFL markets is sharp enough to make the extra tap worth it.

7. betPARX Promo Code TANBONUS

As a newer offer, betPARX keeps things simple by design. Sign up with the betPARX promo code TANBONUS and your first bet is insured up to $50: a loss returns as one bonus bet of equal size, a win pays as usual, and there's no multi-day streak or split tokens to track.

It's a small offer compared to some others here, but for bettors who want one clean wager on Thursday night without extra steps, it's hard to beat for simplicity.

8. Hard Rock Bet Promo Code

For Buccaneers fans watching from home, this one's less about comparing offers and more about availability. Hard Rock Bet is still the only legal mobile sportsbook in Florida, so it's the default option whether or not it's the flashiest on the page.

No Hard Rock Bet promo code needed. Bet $5 on tonight's game and Hard Rock credits $500 in No Sweat Bets, a steep upgrade from what the app offered previously. If you're in a live state, there's little reason to wait.

9. BetRivers Bonus Code

10. Borgata Bonus Code ACTION

Borgata is New Jersey-exclusive, but it's worth a look for anyone in that market. Register with the Borgata bonus code ACTION, bet $20, and get $100 in bonus bet credits right away, with no waiting for the final score.

That immediate turnaround gives it one of the better risk-to-reward ratios on this whole list. The bonus credits expire after seven days, so plan how you'll use them across this weekend's card before you claim them.

NFL Prediction Market Promos

This one's worth a separate mention tonight: the game is at AT&T Stadium in Arlington, Texas (a state with no legal retail or online sportsbooks). For a Texan who wants any kind of action on Bucs-Cowboys, prediction markets aren't just an alternative; they're the only regulated option.

The structure is different from a traditional book. Instead of odds, you buy and sell contracts tied to an outcome, with the price moving as traders take positions. A contract at 80 cents on Dallas, for instance, tells you the market's live win probability directly, with no conversion from American odds required.

1. Polymarket Promo Code ACTION

Deposit $10 with the Polymarket's promo code ACTION and turn it into $25 in trading credit. Markets for tonight's game are live now, alongside futures markets for the rest of the NFL season, so you can build a position beyond Thursday night. Before funding an account, check how that $25 credit converts; it's generally not treated the same as cash you can withdraw.

2. Kalshi Promo Code ACTION2000

Sign up with the Kalshi promo code ACTION2000, clear $25 in qualifying trading volume, and you unlock a bonus worth up to $2,000. Contracts trade from a penny to 99 cents and settle at a full dollar if your side hits. Kalshi has Cowboys-Bucs open right now, alongside longer-term Super Bowl and conference boards, so a position opened tonight can carry forward through the rest of the season.
