Ben AustinA sportsbook bonus can look generous on the screen, but the real test comes after it lands. That is when the clock starts, the payout rules kick in and the headline number gets put to work. Knowing those details can make a big promotion far easier to use well properly.
The first bet loses, the score is settled and then the sportsbook gives you bonus bets instead of cash back. That sounds straightforward until you actually have to use them. The value may be split across several bets, the clock may already be running and a winning bonus bet does not always pay back the way a normal cash wager does.
Bonus Bets Do Not Behave Like Cash
A bonus bet sits in your sportsbook account with a dollar value attached, but it follows different payout rules from ordinary cash. Put $100 of cash on an even-money winner and the return includes your $100 stake. Use a $100 bonus bet at the same odds and the promotional stake is normally removed when the bet settles, leaving the $100 profit as the amount you can withdraw.
That difference is easy to miss when a promotion is advertised with a large headline figure. The useful number is the amount you can actually turn into withdrawable winnings once the bonus bet has been used. Odds therefore play a big part in what comes back, because the promotional credit itself disappears after settlement.
NFL Betting Shows the Scale Behind the Promotions
Sportsbooks are fighting for attention in a huge US market. Americans are expected to legally wager $29.5 billion on the 2026 NFL season through regulated commercial sportsbooks, almost level with the $29.4 billion estimated for the previous season.
That kind of volume helps explain why welcome promotions remain prominent around football. A bonus is part of the cost of winning a new customer in a market where billions of dollars are already being wagered.
A Losing First Bet Can Trigger the Next Stage
First-bet promotions start with real money. You make the qualifying wager, let the result settle and only then does the promotional part begin. A win means the cash bet pays in the normal way; a qualifying loss can activate the bonus-bet return promised by the offer.
The BetMGM welcome offer from the Covers team gives a losing first qualifying wager a second life through bonus bets, with the exact return depending on the size of that opening bet.
The current offer can return up to $1,500 in bonus bets after a losing qualifying first wager. A first bet below $50 produces one bonus bet, while an amount above $50 is divided into five bonus bets worth 20% of the qualifying wager each. A $1,500 loss would therefore produce five $300 bonus bets. That is a very different experience from seeing $1,500 dropped into a cash balance, so the next step is understanding how those credits can actually be used.
Bonus Bets Come With Their Own Clock
Promotional credit can expire, and the countdown may begin as soon as it reaches the account. The BetMGM bonus bets attached to this offer expire after seven days, which puts a clear limit on how long the credit can sit unused.
That deadline changes the practical value of the offer. A bettor who wants to wait several weeks for a particular game cannot assume the credit will still be there. Once the bonus arrives, the expiry date becomes part of the decision about when to place the next wager.
Sportsbook Promotions Are Getting More Scrutiny
Promotional credits have become important enough to attract attention outside sportsbook marketing departments. Philadelphia issued DraftKings a subpoena in April 2026 seeking information about its promotional practices and gambling-harm policies; DraftKings filed a federal lawsuit in July challenging the city’s authority to pursue the investigation.
The dispute concerns the city’s authority rather than a verdict on the value of any particular bonus. It does show that bonus wording and promotional practices are being examined closely, which gives bettors another reason to read the actual conditions instead of stopping at the headline amount.
Winnings Create a Separate Tax Question
A winning bonus bet can turn promotional credit into withdrawable money, but that creates a separate issue in the US: gambling winnings are taxable income. Winnings of $5,000 or more may trigger federal withholding, typically at 24%, and qualifying wins can also lead to Form W-2G reporting.
The tax rule applies to the winnings, regardless of whether the wager began with cash or promotional credit. Keeping accurate records becomes part of using a sportsbook once real winnings start coming back.
The Headline Amount Is Only the Beginning
A sportsbook can put a big number at the top of a welcome offer, but the useful part starts after the qualifying bet settles. Bonus credit may arrive as one bet or several, and it can expire within days. A winning wager then follows its own payout rules.
Knowing those mechanics makes the offer much easier to read before you place the first wager.
