Step 1: Confirm sports betting is legal in your state
As of April 2026, online sports betting is legal in 38 states + Washington DC. Your state matters because operators are licensed state-by-state. Browse our state guide or check our newest legal markets for what's available where you live.
If you're in a state without legal sports betting (CA, TX, FL has only Hard Rock Bet, GA, etc), see our legislation tracker for the bills currently pending. Do not use offshore sportsbooks: they aren't licensed by any US regulator, your money has zero consumer protection, and operators have routinely refused withdrawals from US bettors. Our offshore book blacklist covers the worst offenders.
Step 2: Choose a licensed operator
Every state has a licensed-operator list. The biggest national brands (available in 25+ states) are:
- DraftKings and FanDuel: the two market leaders. Polished apps, deep markets, aggressive promo cadence.
- BetMGM: biggest welcome offers in raw dollars (typically $1,500 first-bet protection).
- Caesars: strong rewards program tying into Caesars resort empire.
- bet365: European operator, reference for live betting and the "Bet $10, Get $365" structure.
- Hard Rock Bet: the only legal operator in Florida.
For a beginner, the choice between DraftKings and FanDuel is largely cosmetic: both ship excellent apps with similar markets. Pick whichever has the bigger welcome offer in your state at sign-up time.
Step 3: Sign up and verify identity
Federal Know-Your-Customer (KYC) regulations require all US-licensed sportsbooks to verify identity before accepting bets. You'll provide:
- Full legal name (matching government ID)
- Date of birth (must be 21+ in most states)
- Last 4 digits of Social Security Number (for identity match)
- Physical address (will be checked against geolocation when you bet)
Verification usually takes under 5 minutes. If your name doesn't match perfectly (e.g. nickname vs legal name), the operator may ask you to upload a driver's license photo. This is standard. Sportsbooks never ask for full SSN, banking passwords, or any payment information by email or phone. If you receive such a request, it's phishing.
Step 4: Make your first deposit
The fastest deposit methods are debit card and PayPal (instant). ACH bank transfer takes 1-3 days but has no fees and supports larger amounts. Avoid credit cards if possible: many issuers code sportsbook deposits as cash advances with high interest.
Start small. $20-50 is plenty for your first deposit. You can always add more later. Most welcome offers trigger on a small first bet ($5-10), so you don't need a large balance to qualify.
Step 5: Place your first bet
The four bet types every beginner needs to know:
Moneyline
Pick which team wins outright. The simplest bet. Prices use American odds: see our American odds guide for the format. Moneylines are the right starting point.
Point spread
The favorite must win by more than the spread; the underdog can lose by less than the spread (or win) to cover. NFL and NBA spreads are the dominant US betting market. Lines typically price -110 on both sides: meaning a $110 bet wins $100 either way.
Total (over/under)
Combined score of both teams over or under the sportsbook's number. Examples: "NBA total 220.5" means the Over wins if combined points are 221+, Under wins if 220 or fewer.
Player prop
A bet on an individual player's stat line: "Mahomes over 275.5 passing yards" or "LeBron over 6.5 assists." Player props have grown to be 30-40% of total US sports-betting handle. Generally higher-vig than main markets, but appealing because they're easy to follow.
The three rookie mistakes that cost most beginners their first bankroll
Mistake 1: Chasing losses
You lose your $20 bet. Your next bet is $40 to "win it back." That loses too. Now your next bet is $80. You're three bets in and risking 4x your original stake. The math: to recover from a 50% drawdown, you need to win 100%, not 50%. Losses compound; chases compound faster.
Fix: set a per-bet stake size (1-2% of bankroll) and stick to it regardless of recent results.
Mistake 2: Parlays as a primary betting vehicle
Parlays compound vig with each leg. A 5-leg parlay typically carries a 25%+ house edge versus ~5% on individual bets. They're entertainment-grade: pleasant to root for, brutal mathematically. See our parlay strategy guide for when parlays actually make sense.
Mistake 3: Betting on every game in your sport
Most NFL Sundays have 13-16 games. The temptation is to bet every game with action. Reality: there's no edge in 80%+ of those games. Pros bet 5-15% of available games per week; recreational bettors should aim for 1-3 games where you have a strong opinion.
