Betting on NBA games comes down to three core skills: understanding American odds, choosing a legal sportsbook in your state, and picking the right bet type for your situation. Master those three things and every other detail — parlays, props, live wagering — falls into place around them.
What Do NBA Betting Odds Actually Mean?
American odds are expressed as positive or negative numbers. A negative number (−160) tells you how much you must risk to profit $100. A positive number (+140) tells you how much you profit on a $100 wager. So if you bet $160 on a −160 favorite and they win, you collect $260 back — your $160 stake plus $100 profit.
On spread and totals bets the standard price is −110 on both sides, meaning you wager $110 to win $100. That built-in margin is the sportsbook's vig, and it produces a house edge of roughly 4.5% on those markets. The effective return on a −110 bet is approximately 95.5 cents per dollar wagered over time — a useful baseline when you're sizing up whether a line looks fair.

What Types of Bets Can You Make on NBA Games?
The four you'll encounter on every sportsbook menu are the moneyline, the point spread, the over/under total, and parlays. Each suits a different situation.
- Moneyline — Pick the outright winner. No spread, no complication. It's the easiest starting point for beginners.
- Point spread — The favorite must win by more than the spread (e.g., −5.5), while the underdog can lose by up to that margin and still cover. Both sides are typically priced at −110.
- Over/Under (total) — Bet on whether the combined final score lands above or below a bookmaker-set number, also usually priced at −110 per side.
- Parlay — Combine two or more bets into one ticket for a larger potential payout. A standard two-team parlay at −110/−110 pays approximately +260, though the true fair-odds payout would be +300 — the gap is the parlay house edge.
- Prop bets — Wagers on specific in-game events such as a player's point total, rather than the game outcome.
- Futures — Season-long bets like NBA Championship winner; these carry higher vig than game lines.
Each type is covered in full on our NBA bet types page covering moneyline, spread, totals, parlays, and props.

Which Sportsbook App Should You Use?
DraftKings, FanDuel, BetMGM, Caesars Sportsbook, and ESPN Bet are the most widely available licensed options across the states listed above. All five offer iOS and Android apps. Welcome offers vary — BetMGM has offered a first-bet match up to $1,500 in bonus bets, Caesars has offered up to $1,000, and both DraftKings and FanDuel have run "Bet $5, Get $200 in bonus bets" promotions — but exact current terms change frequently, so verify directly at each operator's help page before depositing.

How Do You Place Your First NBA Bet — Step by Step?
- Confirm your state is legal. Use the state list above or check your state regulator's site.
- Download a licensed app. Only install apps from the operator's official App Store or Google Play listing.
- Register and verify your identity. Licensed sportsbooks require a government-issued ID and often proof of address (KYC). Submit documents early to avoid withdrawal delays later.
- Make a deposit. Debit cards and PayPal are the most common methods; deposit minimums are commonly $5–$10. Withdrawals to debit card typically take 1–5 business days; PayPal and Play+ often settle within 24–48 hours.
- Find the NBA game and select a bet type. Navigate to basketball → NBA, choose a game, and tap the odds number you want to bet.
- Enter your stake, review the potential payout, and confirm.

Do You Owe Taxes on What You Win?
Yes. All gambling winnings are taxable federal income and must be reported on Form 1040, per IRS Publication 525. Sportsbooks issue a W-2G when a single winning bet pays $600 or more and the payout is at least 300× the wager; federal withholding of 24% applies when a single-wager win exceeds $5,000. State taxes vary. Our page on taxes on NBA betting winnings goes through the specifics.
A Few Things to Watch Out For
Parlay bets carry a noticeably higher house edge than single-game wagers — the gap between a two-team parlay's advertised payout (~+260) and the mathematically fair payout (+300) illustrates this clearly. Futures bets carry even higher vig than game lines. Neither bet type is a bad choice in isolation, but go in with accurate expectations about the math.
Avoid offshore or unlicensed sportsbooks. They operate outside US regulatory frameworks, meaning no consumer recourse if a withdrawal is denied. Always verify a sportsbook's license on the relevant state regulator's official website before depositing real money.
Must be 21+ in most states (18+ in a small number of states — verify with your state regulator). If gambling is affecting you or someone you know, contact the National Council on Problem Gambling's 24/7 helpline at 1-800-GAMBLER.
Ready to Learn How to Bet on NBA Games?
Start with the moneyline — it's the cleanest bet to learn on, and once you understand how American odds translate to dollar amounts, every other NBA wager becomes a variation on that same framework. From there, work through spreads and totals before adding parlays or props. The guides on this site are built to walk you through each stage in order, with real numbers at every turn.
