NFL Betting Promos for Week 4: Odds, Schedule & Predictions

With one game already kicking off, now's a great time to sign up for the best NFL betting promos for Week 4 odds, plus predictions on what will happen on today's schedule. The top sportsbooks and betting sites across America have NFL betting promos lined up as far as the eye can see, but we'll narrow down the best ones, give you the details, and even provide links to get you straight to the end zone.

It's a loaded slate today, with Rams vs. Eagles (1 p.m. ET, FOX) and Jaguars vs. Bengals (1 p.m. ET, CBS) in the early window, followed by the Broncos vs. 49ers (4:25 p.m. ET, CBS) and Chargers vs. Seahawks (4:25 p.m. ET) in the late afternoon. On Sunday Night Football, the Lions vs. Panthers (8:20 p.m. ET, NBC) matchup should be a shootout, and that's exactly what we're looking for in primetime TD parlays. 

NFL Week 4 Odds, Schedule & Predictions

Check out the full NFL Week 4 schedule, plus odds and predictions for games on Sunday, Oct. 4, 2026.

Always check the sportsbook you are wagering on for the most up-to-date odds before any NFL game begins.

Jaguars Moneyline (+125) at Bengals

This is a true revenge spot, considering Jacksonville visited Cincinnati in Week 2 last season and blew a golden opportunity, allowing backup QB Jake Browning to score the go-ahead touchdown late. The Jaguars have the juice to settle that score: Trevor Lawrence has a full complement of weapons, and this Jacksonville defense, led by Travon Walker and Josh Allen off the edge, can get after Joe Burrow. At plus money, you're getting paid fairly for what's only a game-and-a-half favorite on the spread, and live dogs in rematches with a bad taste in their mouth have real betting value.

Cardinals -2.5 (-112) at Giants

Arizona has made a habit of playing tight, low-variance football all season (1-2 straight up, but every game has been competitive), and that profile fits perfectly against a Giants team that is 2-1 on paper, but we all know they're not a legit team right now with Jameis Winston at QB. New York's offensive line issues have been an ongoing story, and that's the exact weakness a disciplined Cardinals front can exploit. The number is right around a field goal, so you're really just betting that Arizona, a team that travels and competes every week, can find three more points than a shaky Giants squad at home. This isn't a Cardinals team that blows anyone out, but it's not one that gets blown out either, which makes them live in a close number like this.

Jets +4.5 (-125) @ Bears

The extra point you're buying up to (+4.5) matters here because Jets-Bears profiles as exactly the kind of one-score, ugly, low-scoring game where that half-point to a full point of cushion can be the difference between a backdoor cover and a bad beat. New York has played two games decided by a field goal or less this season, nearly beating the Packers and Lions in back-to-back weeks. Chicago looked great on Monday night, but they spent a ton of emotion in that game, rallying behind the old man Case Keenum, and I could see a slight letdown by them today.

Best NFL Betting Promos for Week 4

The best NFL betting promos for Week 4 add tons of value to your bankroll. Many of these welcome offers require a first-time deposit or wager to unlock your bonuses, which can come in handy on a slate that could have twists and turns. Let's see what's available on Sunday, Oct. 4, 2026:

1. Fanatics Sportsbook

New users can unlock up to $1,000 in FanCash with the Fanatics Sportsbook promo code ACTION26, which matches qualifying wagers for 10 consecutive days. Bettors wagering $100 or more daily can earn up to $100 per day in bonus funds, while even a $1 wager still triggers a full 100% match. This makes it one of the more flexible NFL betting promos for Week 4, letting new users build toward the full $1,000 total across the full slate of Sunday games. Whether you're betting big or just getting started, this offer gives you extra bankroll all week long.

2. BetMGM

New bettors can lock in a $1,500 First Bet Offer by using the BetMGM bonus code TOPACTION, giving you a safety net on your opening wager this week. If your first bet doesn't cash, BetMGM refunds you in bonus bets up to that $1,500 ceiling, which takes some of the sting out of backing a side in the Jets vs. Bears game. Among the current NFL betting promos for Week 4, this is one of the more straightforward options for bettors who want a cushion on a single big wager rather than spreading bonus funds across multiple days. It's a solid entry point whether you're a first-time BetMGM user or just looking to maximize value on Sunday's slate.

3. bet365

With the bet365 bonus code, new users can turn a modest $10 wager into $200 in guaranteed bonus bets, regardless of whether that first bet wins or loses. That low-risk floor makes it an easy way to get in on the Cowboys vs. Texans game without committing much capital upfront. Compared to other NFL betting promos for Week 4, this structure stands out because it removes the pressure of needing to nail your first pick just to see a return. It's an especially attractive option for bettors who want to test the waters on a Sunday slate without risking much to start.

4. DraftKings

New users can turn a modest $5 bet into $150 in bonus bets with the DraftKings promo code, and that payout lands regardless of whether your first wager actually wins. It's one of the lowest entry points among the NFL betting promos for Week 4, making it an easy way to get started without tying up much of your bankroll. The offer is live across most legal betting states, so most bettors can take advantage heading into Sunday's full slate of games. Whether you're backing a favorite or taking a shot on an underdog, this is a low-risk way to pad your account before kickoff.

5. FanDuel

With the FanDuel promo code , new users just need a $5 minimum deposit and a qualifying $5+ wager each day to start unlocking bonus bets. For each qualifying bet you place, FanDuel pays out $50 in bonus funds, totaling $250 in bonus bets across five days of action. Among the NFL betting promos for Week 4, this stands out as one of the more rewarding options for bettors planning to stay active across the full slate rather than placing just one wager. It's a great fit for anyone looking to spread their action out and maximize value over the week.

6. theScore Bet

New users in most states can claim a $1,000 First Bet Reset using theScore Bet promo code ACTNEWS, giving you a safety net if your opening wager doesn't hit. Where that offer isn't available, a smaller bet-and-get option lets you wager $10 to earn $100 in bonus bets if you win, a lower-risk alternative for more cautious bettors. Compared to other NFL betting promos for Week 4, theScore Bet stands out for offering two distinct structures by state, so check which version applies to you before signing up. Either way, it's a solid option for bettors looking to cushion their first real-money wager of the week.

7. betPARX

Pennsylvania has its own dedicated offer this week: the betPARX promo code TANBONUS. Bettors there can turn a $25 wager into either $50 in bonus bets or a 200% profit boost on a same-game parlay, so you can choose based on how you like to bet. Parlay bettors, in particular, might lean toward the boosted payout option, while straightforward bettors may prefer the guaranteed bonus bet route. If you're in PA and hunting through NFL betting promos for Week 4, this is one of the few state-specific offers worth a look, giving locals some flexibility that national promos don't always include.

8. Hard Rock Bet

Michigan and New Jersey bettors get a tidy little deal this week: a $5 bet turns into $100 in bonus bets courtesy of the Hard Rock Bet promo code. That's a 20x return on a tiny stake, no complicated tiers or daily requirements involved, just one bet and you're set. It's a stripped-down alternative to some of the more elaborate NFL betting promos for Week 4, which makes it appealing if you'd rather not juggle multi-day offers or parlay boosts. For bettors in those two states, it's a quick, low-commitment way to add some bonus cash before Sunday's games kick off.

9. BetRivers

Here's one that scales with where you live: the BetRivers bonus code hands out a second-chance bet if your first wager misses, but the ceiling shifts by state. Michigan and Pennsylvania bettors get up to $500 back, New Jersey tops out at $250, and West Virginia caps things at $100. It's a different flavor than most NFL betting promos for Week 4: no upfront cash is needed, and the value kicks in only if your opener doesn't cash, making it more like insurance than a bonus. Worth checking which bracket applies to your state before you fire off that first bet.

10. Borgata

No waiting around with this one: New Jersey bettors who use the Borgata bonus code ACTION get $100 in bonus bets credited instantly after a $20 wager, win or lose, no delayed payout or multi-day grind required. That instant turnaround sets it apart from several other NFL betting promos for Week 4 that make you wait on a settled bet or string together daily qualifiers. It's a simple, fast-moving offer for NJ bettors who'd rather get their bonus funds in hand right away and start using them on Sunday's games. Quick, uncomplicated, and done in one shot.

Best NFL Prediction Market Promos

Bettors who prefer exchange-style markets can also shop NFL prediction market promos for the London game and the rest of the Week 4 slate.

1. Polymarket

Prediction market bettors can use the Polymarket promo code ACTION to turn a $10 deposit into a $25 trading bonus. It's an exchange-style alternative to traditional sportsbooks, where you're trading contracts on game outcomes rather than placing a standard wager. Among this week's NFL prediction market promos for Week 4, Polymarket stands out for its wide state availability, covering more than 40 states where the platform currently operates. It's a solid entry point for bettors curious about trying the prediction market format on London game day and beyond.

2. Kalshi

New accounts can unlock up to $2,000 in bonuses with the Kalshi promo code ACTION2000, one of the larger ceilings among this week's offers. Kalshi operates as a regulated exchange, so instead of a conventional bet, you buy and sell contracts tied to real-world outcomes, including NFL game results. This structure differs from sportsbook-style NFL prediction market promos for Week 4, giving bettors the chance to trade in and out of positions rather than lock in a single wager. With broad state availability, it's worth a look for anyone wanting to diversify beyond a traditional bonus bet format.
