Best Sportsbook Promos: How To Judge Which Offers Are Actually Worth Claiming
Affiliate disclosure: OddsShopper may earn a commission when you sign up at a sportsbook through our links. That never changes our advice. Our whole model is helping you find the best price at whatever book you bet.

Every sportsbook leads with the biggest number it can advertise. "Bet $5, get $250." "Up to $1,000 back." "$1,500 first-bet safety net." Picking the best sportsbook promos looks like a game of finding the biggest headline, but the headline is the easy part. The part nobody shows you is how much of that number turns into cash you can actually keep, and how to tell a truly strong offer from one that looks big and pays little. The whole job here is simple: read any promo by its expected value, not its font size, and then squeeze more out of it once it hits your account. And there's one move most bettors miss entirely — a way to make a sign-up offer you were already going to claim pay you a second time. We'll get to that; it's the best promo on this page. This evergreen guide skips the dated "offer of the week" churn and gives you the framework that works on every promo, in every state, all season long.

In Summary
- Judge Every Offer By Expected Value, Not The Headline Number. A "$250 in bonus bets" promo is really worth about $150-$175, because bonus bets pay winnings only and expire fast.
- The Biggest Headlines Hide The Most Strings. Deposit matches carry rollover and minimum-odds requirements that quietly shrink them; simple "bet $5, get bonus bets" offers usually keep more of a smaller number.
- Priority Order For A New Bettor: claim strong sign-up offers one book at a time, opt into weekly reloads, and take odds boosts only when the boosted price actually beats the true market.
- The Best Promo Of All Is Stackable: claim a partner sportsbook's offer through OddsShopper and you can get a free month of OddsShopper Pro on top of it.
- Then Shop The Line. The bonus gets you in the door; the price you take on each bet decides how much you keep.
The Main Types Of Sportsbook Promos (And What Each Is Really Worth)
Almost every offer at DraftKings, FanDuel, BetMGM, Caesars, Fanatics, or bet365 is a variation on a handful of promo types. Learn the types and you can size up the best sportsbook bonuses in seconds — the biggest headline is rarely the best deal.
| Promo Type | How It Works | What It's Really Worth | The Catch to Check |
|---|---|---|---|
| Sign-Up Bonus Bets ("Bet $5, Get $250") | You place a small qualifying first bet; the book credits bonus bets once the promo terms are met (often regardless of outcome, sometimes only if the qualifier wins) | Bonus bets are not cash, so discount them (see the EV section) | Bonus bets return winnings only, not the stake; short expiration |
| First-Bet Safety Net ("Up To $1,500 Back") | If your first real-money bet loses, you get that amount back as bonus bets | Strong for a confident larger first bet, but only pays out if you lose | The refund is bonus bets, not cash; one bet only |
| Deposit Match ("50% Up To $1,000") | The book matches part of your deposit as a bonus balance | Depends entirely on the playthrough requirement | Rollover (e.g. 10x) at a minimum odds you must clear before withdrawing |
| Odds Boost / Profit Boost | A specific market gets a better-than-listed price, or your winnings get a percentage bump | Real value only when the boosted price beats the true market price | Caps on stake and on the boosted payout |
| Reload / Recurring Promo | An ongoing offer for existing users (boost tokens, parlay insurance, weekly bonuses) | The quiet workhorse; small edges that add up over a season | Often opt-in each week; easy to forget to claim |
| Referral Bonus | You and a friend each get credited when they sign up and bet | Clean value if you actually know a new bettor | Both sides usually must place a qualifying wager |
The pattern to notice is the one that decides everything downstream: the biggest headline numbers (deposit matches, safety nets) come with the most strings, while the plain "bet $5, get $X" offers are simpler but pay in bonus bets you have to convert. Neither is automatically better. The math is, and the math is next.
How To Read A Promo By Expected Value (EV)
Expected value is just the average result of an offer if you could claim it over and over. A promo is worth claiming when its EV is clearly positive after you discount the parts that are not cash. You do not need a spreadsheet, just two habits.
Habit 1: discount bonus bets to their real cash value. A bonus bet is not a dollar. When you win with one, the book pays you the profit but keeps the stake, so a $100 bonus bet that wins at even money returns $100, not $200. Because of that, and because you cannot save them for the perfect spot, bonus bets are worth less than face value. A common rule of thumb is that a bonus bet converts to roughly 60 to 70 cents of real cash per dollar, depending on how you use it. So a "$250 in bonus bets" headline is closer to $150 to $175 of real value. That still clears a $5 first bet with room to spare, which is why simple sign-up offers are usually worth claiming when the terms are fair. (Our free bet value calculator runs this conversion for you, and what a free bet actually is breaks down the mechanics.)
Habit 2: price the playthrough on a deposit match. This is where big headlines quietly shrink. Say a book offers a 50% deposit match up to $1,000 with a 10x rollover.
Worked example. You deposit $1,000 and get a $500 bonus. A 10x rollover on the bonus means you must wager $5,000 before you can withdraw. (Watch the terms: some books apply the rollover to your deposit plus bonus, which pushes the requirement well above $5,000.) If you clear it on roughly even-money -110 markets, you give up roughly 4.5% of everything you wager to the vig, so putting $5,000 through costs you around $225 in expected losses. Your expected take-home from the $500 bonus is about $500 minus $225, or near $275, and it shrinks further if the terms force you onto worse-priced markets to clear it. Still positive, but a long way from the $500 the ad implied.
The single most useful line in that example is the last one: the "$500" was really about $275 before the fine print even got involved. Put the three headline styles side by side and the discount shows up in plain numbers:
| Headline You See | What it really converts to | Why the gap exists |
|---|---|---|
| "$250 In Bonus Bets" Sign-Up | $150–$175 real cash | Bonus bets pay winnings only and expire fast (60–70¢ per $1) |
| "50% Match Up To $1,000" ($500 Bonus, 10X Rollover) | $275 expected take-home | $225 lost clearing a $5,000 playthrough at -110 |
| "Profit Boost +100 → +120" | Value only if +120 beats the true price | Many boosts start from a padded number, not a fair one |
The row I keep coming back to is the last one: a boost is the only promo on this list that can be worth exactly zero even when it "hits," because a boosted +120 that's still worse than the no-vig market hands the book its edge back on your own bet. Run both habits and the ranking becomes obvious. A low-friction "bet a little, get bonus bets" offer usually beats a giant deposit match with heavy rollover, because you keep more of a smaller number. The best sportsbook promos are the ones where the real, discounted value clears the strings by a wide margin — which means the fine print is where you find them.
The Fine Print That Quietly Kills Promo Value
Two offers with the same headline can be worlds apart once you read the terms. Before you claim anything, scan for these:
- Playthrough / Rollover. How many times must you wager the bonus before withdrawing? 1x is great, 10x is heavy, 15x-plus is often not worth it.
- Minimum Odds. Many bonuses only count qualifying bets at a minimum price, say -200 or longer, so a heavy -300 favorite would not count. The tighter that floor, the more the requirement costs you to clear, because it pushes you toward longer, higher-variance prices.
- Bonus Bets Vs. Cash. Winnings are usually paid as withdrawable cash, but the bonus stake itself is not returned. Know which you are getting.
- Expiration. Bonus bets and boost tokens often expire in 7 days. An offer you cannot realistically use in time is worth zero.
- Maximum Payout / Stake Caps. Odds boosts and safety nets almost always cap how much you can win or wager, which quietly limits the upside.
- One Per Household / New Users Only. Sign-up offers are one-time. Do not burn a big welcome bonus on a throwaway bet.
- State Availability. Every promo is limited to states where that sportsbook is legal, and the same welcome offer can differ from one state to the next. Confirm the current offer and its terms in your own state before you claim.
If a promo hides a 15x rollover at -300 minimum odds behind a huge dollar sign, that is not a good offer wearing a big number. That is a small offer wearing a big number. Once you can spot the difference, the only question left is which offers to claim first.
Sign-Up Bonuses Vs. Reloads Vs. Odds Boosts: Which To Prioritize
For a new bettor, the priority order is usually straightforward:
- Claim the strong sign-up offers first, one book at a time. A low-stake "bet $5, get bonus bets" welcome offer usually clears its strings comfortably when the terms are fair — the bonus is meaningful, the qualifier is cheap, and there's no heavy rollover attached. Work through the major books (DraftKings, FanDuel, BetMGM, Caesars, Fanatics, bet365) one at a time so you actually use each bonus before the next.
- Opt into reloads and profit-boost tokens every week. These are small, but they are the edge that separates bettors who leave value on the table from those who do not. Set a weekly reminder to claim them.
- Take sportsbook odds boosts only when the boosted price beats the real market. A boost from +100 to +120 is only good if +120 is better than the true, no-vig price of that outcome. Plenty of "boosts" start from a padded number and end up no better than a fair price elsewhere. This is exactly where a line-comparison tool earns its keep.
The reason you keep multiple books is not just more bonuses. The same bet is priced differently at each one, and the best price is rarely at the book giving you the flashiest promo. That last point is the whole reason the next two sections exist.
Prediction Markets Are Changing The Promo Landscape
Alongside traditional sportsbooks, event-contract platforms like Kalshi and peer-to-peer betting exchanges now run their own sign-up credits and deposit bonuses. They work differently enough that you can't judge their promos on autopilot. Instead of a sportsbook's built-in margin (the vig) baked into the listed odds, these platforms can charge an explicit fee and make you pay through the bid-ask spread, so your real cost depends on the fee, the liquidity, and the price you can actually get filled at — not a headline "no vig." Before you claim a bonus on one, run this quick checklist:
- Is It Live In Your State Today? Availability for sports-style contracts is actively disputed and changes fast — confirm before you deposit, not after.
- Is The Promo Cash, Credits, Or A Fee Rebate? A fee rebate is worth far less than an equal amount of withdrawable cash.
- What's The Real Cost To Enter? Add the fee to the spread you'd cross; that's your true price, the same way vig is on a sportsbook.
- How Does It Resolve And Pay Out? Know how the contract settles and how quickly you can withdraw before you tie up money.
Judge any bonus there by the same EV test from the section above, just with fees and spread standing in for vig. The point isn't "always use them" — it's that "sportsbook promos" now covers a wider field than it did a year ago, and the smart move is to price the real cost after any bonus, wherever you bet.
The Best Promo On This Page: A Free Month Of OddsShopper Pro
Here is the move I promised at the top, and the one almost nobody claims. You are going to sign up at a sportsbook for its welcome offer anyway. When you do it through OddsShopper's partner links, that same sign-up can also earn you a free month of OddsShopper Pro — the +EV screen and line shopping toolset that does all the EV math from this guide for you. You're not choosing between the sportsbook's bonus and ours. You get both from a single sign-up.
The free subscription offer works in four steps:
- Pick a sportsbook promo from OddsShopper's partner list, organized by your state.
- Sign up and deposit at that book, following its promo requirements — the same welcome offer you were going to claim anyway.
- Place your qualifying first bet at that sportsbook.
- Email proof to support@oddsshopper.com — a screenshot of the book's welcome email and a screenshot of your placed bet — and we credit your free month of OddsShopper Pro.
Think about what that does to the math. Remember that "$250 in bonus bets" that was really worth about $150 to $175? Claim it through the free-subscription offer and you also pick up a month of the exact tool that tells you which of your next bets are actually +EV and which book has the best number on each one. The sportsbook bonus gets you in the door once. A free month of Pro is what makes every bet after it worth more. That stack is one no "bet $5, get $250" headline can match on its own. (Eligibility follows each sportsbook's own terms and your state's legal betting age.)
Turn Any Bonus Into Real Value: Shop The Line After You Claim
Whether you grab the free month or not, the price you take on each bet is where a bonus lives or dies. If you bet the Chiefs at -130 on one book while another has them at -115, you have handed back a chunk of your bonus on a worse number before the game even starts. A one-time bonus gets wiped out fast if you keep taking stale or overpriced lines on every bet after it.
OddsShopper does exactly that. Our free OddsShopper Odds Screen lines up the major books side by side so you can see, instantly, who has the best price on the bet you want, so your welcome bonus goes further instead of getting eaten by a bad number. (New to it? Here is how the Odds Screen works, step by step.)
New to OddsShopper? The tool scans every major sportsbook and flags the bets priced in your favor, then shows you the best available number on each one, automatically. That means every bonus bet and every real-money wager goes down at the best price on the market instead of whatever one app happened to post. Even better, the same partner sign-up you make through OddsShopper can also land a free month of OS Pro. Prefer to just subscribe? Code PROMOEV20 takes 20% off OS Pro.
For bettors who want to go further, OS Pro's +EV and line shopping tools do the discounting and price-checking from this whole guide for you: they convert a bonus-bet headline into its real cash value, then compare the price you are about to take against the true no-vig market and tell you whether a bet, or a boost, is actually in your favor. It's the automated version of the two habits above — which is exactly what the free month gets you a taste of.
Book-by-Book Promo Guides
This page is the hub. The reason each book needs its own guide is that the framework above lands differently at each one: the same "welcome offer" hides a different rollover, a different minimum-odds floor, and a different rewards program, and that fine print is exactly where a headline turns into real value or quietly loses it. So each spoke pins down that book's current welcome terms, where to find its sportsbook promo codes, how its ongoing boosts and rewards actually pay, and how to line-shop your first bet so the bonus stretches further. Guides rolling out cover the major sportsbooks: Caesars Sportsbook, DraftKings, FanDuel, BetMGM, Fanatics, and bet365, plus pick'em apps like Sleeper (a fantasy-style product with its own promos, not a traditional sportsbook). Bookmark this page and check back as each one goes live.
Frequently Asked Questions
Are sportsbook promos worth it? The best ones clearly are. A simple "bet $5, get bonus bets" sign-up offer usually clears its strings comfortably even after you discount the bonus bets to real cash. The offers to be cautious with are big deposit matches buried under heavy rollover and tight minimum odds, where the real value is a fraction of the headline.
What is the best sportsbook promo I can claim? For most bettors it is the stack: claim a partner book's welcome offer through OddsShopper's free subscription offer so the same sign-up also earns you a free month of OddsShopper Pro. You get the sportsbook's bonus and the tool that helps you maximize every bet after it.
What is a bonus bet worth in real money? Less than its face value, because a winning bonus bet pays your profit but keeps the stake, and you cannot wait for the ideal spot to use it. A common rule of thumb is 60 to 70 cents of real cash per dollar of bonus bet, depending on how you use it.
What is playthrough or rollover on a deposit match? Rollover is the number of times you must wager a bonus before you can withdraw it. A 10x rollover on a $500 bonus means betting $5,000 first. The higher the rollover and the tighter the minimum odds, the more that requirement quietly costs you.
What is the best sportsbook promo for beginners? Start with the low-friction sign-up offers ("bet a little, get bonus bets") at the major books, one at a time, so you actually use each bonus before moving on. Then opt into weekly reloads and take odds boosts only when the boosted price beats the true market number.
Are prediction market promos different from sportsbook promos? Yes and no. Platforms like Kalshi and peer-to-peer betting exchanges can charge an explicit fee and make you pay through the bid-ask spread instead of a sportsbook's vig, so your real cost depends on the fee, the liquidity, and the price you actually get. You still judge any bonus there by the same expected-value test — just with fees and spread standing in for vig, and only after confirming the platform is available in your state.
The Bottom Line
A promo's headline number is marketing; its expected value is the truth. Discount bonus bets to real cash, price the playthrough on any deposit match, and scan the fine print for rollover, minimum odds, and expiration before you claim. Do that and you'll stop chasing the biggest font and start claiming the offers that actually clear their strings — then stack a free month of OddsShopper Pro on a sign-up you were making anyway, and let the best price on every bet after it do the quiet work the headline never mentioned.
Ready to make every bonus go further? The best deal is free: claim a partner sportsbook offer through OddsShopper and get a free month of OS Pro so your welcome bonus buys more than it would at any single app. Would rather subscribe outright? Code PROMOEV20 takes 20% off OS Pro.
