The 2026 NFL dates that drive DFS value
Season dates verified against the NFL's published Week 1 schedule. The practical takeaway: have your accounts registered, verified and funded before Wednesday, September 9 — not on game night.
Kickoff Game
Wed, Sept 9, 2026New England Patriots at Seattle Seahawks, 8:20 p.m. ET at Lumen Field (NBC/Peacock/NFL+). A Super Bowl LX rematch against the defending-champion Seahawks — and the first Wednesday season opener since 2012.
Week 1 Main Slate
Sun, Sept 13, 2026The main Sunday slate — the biggest DFS contest day of the young season. Week 1 spans 16 games across four days, so there is a qualifying slate almost every night.
Week 1 Monday Night
Mon, Sept 14, 2026Denver Broncos at Kansas City Chiefs, 8:15 p.m. ET — the last chance to put Week 1 volume through a fresh signup bonus.
How NFL DFS sign-up bonuses work
September offers come in three structures, and the structure matters more than the headline number. Deposit matches mirror your first deposit as bonus funds that clear into withdrawable cash once you satisfy a playthrough — 1x is friendly, 3x demands real volume. Bonus entries and entry credits (the structure Underdog and the pick'em operators now favor) are contest tickets rather than cash: winnings from them withdraw normally, the credits themselves never do, and they expire quickly. Win-conditional offers only pay if your first entry hits, so their expected value is a fraction of the headline. The full mechanics are in our DFS Bonus Types Explained guide.
Two rules apply to every operator: new-user offers are one per person, ever — you cannot re-claim next season — and the terms on the signup screen always override whatever any third-party site (including this one) says about them.
Operator-by-operator: what we could verify for kickoff
We re-checked every operator on August 8, 2026. Statuses below are honest: "verified" means we read the offer on the operator's own page that day; "reported" means the best available evidence is media or tracker reporting; "rotates" means the operator changes its offer seasonally and the live signup screen is the only source of truth.
Underdog Fantasy
Best Ball drafts + Pick'em
Play $5, get $50 in Bonus Entries — code UDPROMO
The only headline DFS offer we could verify on an official operator page in August 2026 (underdogsports.com — note the rebrand from underdogfantasy.com). Enter $5 in real-money contests and Underdog credits $50 in bonus entries; winnings from the entries pay as withdrawable funds, the entries themselves do not cash out. Industry trackers report a 14-day expiry and exclusions in MD, MI, NJ, NY, OH and PA — confirm both in-app. Best Ball draft season peaks before Week 1, making this the natural first claim of September.
DraftKings
Salary-cap DFS, Showdown, Pick6
New-user offer rotates for NFL kickoff
DraftKings rotates its DFS welcome offer with the calendar, and NFL kickoff is its biggest new-user window. We could not verify the live offer against an official page in August 2026, and third-party reports conflict — reported structures include bonus-pick credits and a Week 1 contest-ticket bundle. The last terms we fully verified (June 2026) were a deposit match worth up to $500 at 1x. Read the exact offer on the signup screen before depositing.
FanDuel
Salary-cap DFS, Single-Game, FanDuel Faceoff
Welcome package + reported $5-for-$25 Picks offer
FanDuel blocked our August 2026 re-verification, so no live numbers here. The welcome package we last verified (June 2026) combined a deposit match and entry credits worth up to $100. If you are in one of the mostly non-sportsbook states running FanDuel Picks, media reporting from June 2026 describes a play-$5-get-$25-in-credits new-user offer with a 7-day credit expiry — treat it as reported, and check the signup screen.
Sleeper
Pick'em + season-long leagues
Up to $100 match — plus a reported $20 no-deposit bonus
Sleeper's official promo page was unavailable in August 2026, but multiple industry trackers consistently report the same package: a 100% first-deposit match up to $100 at a 1x playthrough ($10 minimum deposit), plus $20 in bonus credit at verified signup before any deposit. Codes are reported to apply at the deposit screen, not account creation. A natural fit if your home league already lives on Sleeper.
BetMGM
Fantasy + MGM Rewards crossover
Fantasy match unverified — sportsbook offers confirmed
We could not re-verify BetMGM's fantasy deposit match in August 2026 (last verified June 2026: 100% up to $250 at a steep 3x playthrough). What BetMGM's own blog did confirm on August 8, 2026 are its sportsbook new-customer offers — up to $1,500 back in bonus bets on a losing first bet, or $150 in bonus bets if a $10 first bet wins, one offer per new customer, bonus bets expiring in 7 days. Those are sportsbook terms, not DFS terms; third-party trackers list the $1,500 offer through September 1, so expect a kickoff refresh.
Also on the radar
The Week 1 signup strategy
1. Register early, deposit late. Identity verification and geolocation are the two failure points, and both get worse under kickoff-night load. Create and verify accounts the week before September 9; time each deposit to the slate you will actually play.
2. Match the offer structure to your calendar. Credit- and entry-based offers expire in days, not months. Claiming a 14-day bonus-entry offer in late August burns its clock before the season starts; claiming it the week of September 9 lets the entries ride the Kickoff, Sunday and Monday slates. Long-window deposit matches are the ones you can claim early.
3. Sequence verified offers first. Start with what is confirmed (Underdog's $5-for-$50 is the verified headline as of August 8), read DraftKings' and FanDuel's live signup screens next, and treat everything else as a bonus, not a plan.
4. Use the Sunday slate to clear playthrough. The September 13 main slate is the deepest contest day of the young season — the easiest place to generate the entry volume a deposit match requires without forcing bets you would not otherwise make.
5. Deposit to your bankroll, not the cap. A bonus ceiling is not a target. Deposit what your season bankroll supports; a half-claimed match you clear beats a maxed one you abandon.
6. Confirm eligibility before funding. State rules and per-offer exclusions differ — check the Legal States Guide, then our step-by-step promo-code walkthrough if any code field trips you up. The comparison matrix stays the fastest way to line the offers up side by side.
