Illinois Sportsbook Promo Codes: Every Active Code 2026
Every working Illinois sportsbook promo code in one place — DraftKings, FanDuel, BetMGM, Caesars, BetRivers. Check expiry before you use them. 21+.
Promo codes can unlock a welcome offer — or do nothing if they've expired. Here's a current look at every active Illinois sportsbook promo code, what each one gets you, and what to watch before you use it.
Which Illinois sportsbook promo codes are active right now?
All five major licensed operators in Illinois — DraftKings, FanDuel, BetMGM, Caesars, and BetRivers — run welcome promos for new sign-ups. Codes and offer structures change frequently, so always confirm live terms on each operator's Illinois-facing promo page before you deposit. Per operator T&C, bonus bets are non-withdrawable; only winnings from a bonus bet can be cashed out.
| Sportsbook | Promo Code | Offer Type | Key Condition |
|---|---|---|---|
| DraftKings | Check operator site | Bet-and-get bonus bets | Place qualifying first wager; bonus bets issued on settlement |
| FanDuel | Automatic (no code needed) | No-sweat first bet | First bet must lose to trigger refund as bonus bets |
| BetMGM | Check operator site | Bonus bet on first deposit | Minimum deposit and odds requirements apply |
| Caesars | Check operator site | First-bet match up to stated amount | Single-game wager restrictions may apply |
| BetRivers | Check operator site | Deposit match bonus | Rollover requirement applies before withdrawal |
Exact bonus amounts are not listed here because they change often and publishing a stale number does you real harm. Go to the cashier or promo page inside each app to see the figure tied to your promo code on the day you sign up.
How do I use an Illinois sportsbook promo code?
The process is the same at virtually every book. Create an account, enter the code in the "promo code" field during registration or at first deposit, meet the minimum deposit, and place the qualifying wager. Miss any one step and the offer may not apply. Some books like FanDuel apply the offer automatically without a code — entering a wrong code can actually block the automatic credit, so double-check first.
Bonus bet expiry windows commonly run 7–30 days after issue, per standard US sportsbook practice. A code tied to a specific event (a playoff game, for instance) may expire the moment that event ends. For a deeper look at how these mechanics work, see our guide on how Illinois sportsbook promos work and what bonus bets actually mean.
What happens if a promo code has expired?
Nothing — the code simply won't apply and you'll get no bonus. The operator won't warn you at checkout in every case. If you're unsure, visit the Illinois Gaming Board sports wagering page to confirm a book is still licensed, then go straight to that book's current promo page for a live code.

Are winnings from promo codes taxable?
Yes. Winnings generated by bonus bets are ordinary income under federal and Illinois state tax law. The IRS requires a W-2G for winnings of $600 or more at 300× the wager, or $5,000 or more regardless of multiplier. The promo credit itself is generally not taxed until it produces a payout. Illinois does not allow gambling losses as a state deduction. See our full guide on taxes on Illinois sportsbook winnings for more detail, or consult IRS Topic No. 419 directly.
