Online vs. Retail Sports Betting

The Mobile Betting Revolution

Mobile sports betting has fundamentally reshaped the industry. In states that allow both online and retail betting, mobile apps typically account for 80-90% of total handle (amount wagered). The convenience of placing a bet from a smartphone has driven explosive growth — states that launch with mobile betting generate significantly more tax revenue than those limited to retail-only operations.

However, not all legal sports betting states allow mobile wagering. Some states have authorized only retail (in-person) sportsbooks at casinos, racetracks, or tribal facilities. Others have launched with retail only and later added mobile. The distinction between online and retail is one of the most important factors in understanding a state's sports betting market.

How Geofencing Works

Every legal mobile sports betting app uses geofencing technology to verify that the user is physically located within state borders before allowing a bet to be placed. This is a federal requirement — the Wire Act prohibits interstate sports wagering, so operators must ensure bets originate within the state where they are licensed.

Geofencing uses a combination of GPS, Wi-Fi triangulation, and cell tower data to determine location. Most operators use GeoComply, the dominant geolocation compliance provider, which processes billions of location checks annually. The technology is accurate to within a few meters, though users near state borders may experience issues.

Practical implications for bettors:

• You must be physically present in a legal state to place a bet — VPNs will not work and will get your account flagged
• You can create an account from anywhere, but you can only deposit and wager while within state lines
• If you travel to another legal state, you may need to download that state's version of the app or register with a different operator
• Border areas (within ~1 mile of state lines) may have intermittent geofencing issues

Major Online Operators

The legal sports betting market is dominated by a handful of major operators that hold licenses in multiple states:

• FanDuel Sportsbook: The market leader by handle in most states. Owned by Flutter Entertainment. Known for a user-friendly app and aggressive promotional offers.
• DraftKings Sportsbook: The second-largest operator nationally. Publicly traded (DKNG). Strong in same-game parlays and live betting features.
• BetMGM: Joint venture between MGM Resorts and Entain. Leverages MGM's casino brand and loyalty program.
• Caesars Sportsbook: Backed by Caesars Entertainment. Integrated with the Caesars Rewards loyalty program.
• ESPN BET: Launched in 2023 through a partnership between ESPN and Penn Entertainment. Leverages ESPN's media reach.

In addition to these national operators, some states have local or regional operators, and tribal casinos may operate their own sportsbook apps under tribal compacts.

Retail Sportsbook Experience

Retail sportsbooks are physical locations where bettors can place wagers in person. These are typically located at:

• Commercial casinos: Most casino-based sportsbooks offer dedicated betting lounges with large screens, betting windows, and self-service kiosks.
• Racetracks: Many states authorized sports betting at existing horse racing facilities, which already had wagering infrastructure.
• Tribal casinos: In states with tribal compacts, tribal casinos may be the exclusive or primary venue for retail sports betting.
• Standalone sportsbooks: A few states allow standalone sports betting facilities not attached to a casino or racetrack.
• Bars and restaurants: Some states (like Montana and South Dakota) allow sports betting terminals at licensed bars and restaurants.

The Retail-Only vs. Mobile Debate

States that restrict sports betting to retail-only locations generate significantly less revenue and tax income than states with mobile betting. The data is clear:

• New Jersey (mobile + retail): Over $1 billion in monthly handle, with 90%+ from mobile
• Mississippi (retail only): Approximately $30-40 million in monthly handle
• New York (mobile + retail): Over $1.5 billion in monthly handle after mobile launch, compared to ~$50 million retail-only

The argument for retail-only is typically based on responsible gambling concerns — the theory being that requiring bettors to physically travel to a location creates a natural friction that reduces problem gambling. However, research on this point is mixed, and critics argue that retail-only models simply push bettors to illegal offshore sites that offer no consumer protections.

Cross-Border Considerations

If you live near a state border or travel frequently, understanding the cross-border rules is essential:

• Your account is tied to the state where you registered, but you can only bet while physically in a legal state
• Some operators (FanDuel, DraftKings) maintain a single wallet across states — your balance travels with you
• Other operators require separate accounts or registrations in each state
• Winnings may be taxable in the state where the bet was placed, not where you live — consult a tax professional
• Promotional offers and odds may vary by state due to different regulatory requirements
