Welcome to USA.bet, your independent guide to online betting and event-based trading in the United States.
Whether you’re comparing sportsbooks, looking for a licensed online casino, or exploring prediction markets such as Kalshi and Polymarket, the first question is the same: What’s available where you live or travel?
Gambling laws vary considerably between states. Our guides help you understand these differences, evaluate platforms, and make more informed decisions.

Prediction Markets
Prediction markets let eligible users trade contracts based on the outcome of real-world events, including sports, elections, economic indicators, and cryptocurrency prices.
Platforms such as Kalshi and Polymarket US differ from conventional sportsbooks in how their contracts are priced, traded, and settled. Trading fees, liquidity, and state restrictions are important considerations.
Online Sportsbooks
Compare regulated sportsbooks offering NFL, NBA, MLB, NHL, college sports, and other markets. Learn about betting odds, mobile apps, promotional terms, and state-specific restrictions.
Real-Money Online Casinos
Find licensed online casinos featuring slots, blackjack, roulette, and live dealer games. Real-money online casinos operate in fewer states than sportsbooks, so location is particularly important.
Horse Racing & Racing-Powered Games
Compare pari-mutuel horse racing platforms and discover newer racing-powered games, which use casino-style interfaces to display the outcomes of underlying horse racing wagers.
U.S. Betting in Numbers
The U.S. gambling market continues to expand, while prediction markets have introduced a distinct, rapidly growing category of event-based trading.
| Market indicator | Latest reported figure |
|---|---|
| States with legal sports betting in some form | 39 states + Washington, D.C. |
| States with operational real-money online casinos | 7 |
| U.S. regulated sports betting handle, 2025 | $166.94 billion |
| U.S. regulated online casino revenue, 2025 | $10.74 billion |
| Kalshi and Polymarket combined global trading volume, July 2026 | Approximately $53 billion |
What the numbers mean: Sports betting handle is the total amount wagered, while online casino revenue is the amount operators retain after paying out player winnings. Prediction market trading volume measures contracts traded and does not equal either operator revenue or U.S.-only betting handle.

Featured Online Betting Platforms
Different operators specialize in different products. These featured platforms cover sportsbooks, online casinos, and horse racing, but none is available for every type of betting in every U.S. state.
FanDuel — Sports Betting, Casino & Racing
FanDuel is one of the most established U.S. betting brands, with separate products for sports wagering, real-money casino games, and horse racing.
FanDuel Sportsbook offers pregame and live sports betting in eligible states. FanDuel Casino operates in selected regulated online casino markets, including New Jersey, while FanDuel Racing focuses on pari-mutuel horse racing.
These are distinct products with different geographic restrictions, account requirements, and promotional terms.
Why consider FanDuel? Its range of products makes it particularly relevant for bettors interested in more than one category.
Hard Rock Bet — Sportsbook & Online Casino
Hard Rock Bet operates a state-regulated sportsbook and online casino in New Jersey under the Hard Rock Hotel & Casino Atlantic City license.
The sportsbook covers major professional and college sports, while its casino offers slots, table games, and other real-money games.
Hard Rock Bet also offers sports betting in other U.S. jurisdictions, but customers should check which products are authorized in their location.
Why consider Hard Rock Bet? It combines a recognized gaming brand with regulated sports betting and online casino products.
Betinia — New Jersey Online Casino
Betinia is a newer entrant to New Jersey’s regulated real-money online casino market.
The website operates under the authorization of Caesars Interactive Entertainment New Jersey and provides an alternative to the state’s longer-established casino brands.
Betinia focuses on online casino gaming, including slots and other real-money games. Customers must be at least 21 and physically located in New Jersey to participate.
Why consider Betinia? It offers NJ players another licensed casino option to compare for games, usability, payments, and promotional conditions.
AmWager — Dedicated Horse Racing Platform
AmWager specializes in advance-deposit wagering (ADW) on horse racing rather than traditional sportsbook or casino products.
Customers can access race information, racing video, pari-mutuel betting pools, and wagering tools.
Unlike fixed-odds sports betting, pari-mutuel payouts depend on the money wagered into the relevant pool and applicable deductions.
AmWager requires customers to be at least 21 and is available only in approved jurisdictions. Its published state restrictions exclude New Jersey.
Why consider AmWager? It is a specialist platform for bettors interested in horse racing rather than a general-purpose gambling app.
Affiliate disclosure: USA.bet has commercial relationships with selected operators and may receive compensation for qualifying referrals. Featured placement identifies relevant platforms, not a guarantee of superior odds, returns, or promotional value. Eligibility and offer terms must be verified with the operator.
Prediction Markets in the USA: How Do They Compare?
Prediction markets have attracted substantial attention in 2026, especially as sports-related event contracts have become more popular.
According to Pew Research Center, combined worldwide trading volume on Kalshi and Polymarket increased from approximately $26 billion in May to $53 billion in July 2026. Sports contracts drove much of that growth.
However, prediction markets extend beyond sports. Available contracts may cover election outcomes, economic announcements, interest-rate decisions, cryptocurrency prices, and other measurable events.
How Do Event Contracts Work?
Consider a simple yes-or-no contract priced at $0.60.
If you purchase 100 contracts at that price, your initial cost is $60 before fees. If the event occurs and the contracts settle at $1 each, you receive $100, resulting in a $40 profit before fees.
If the event does not occur and the contracts settle at zero, you lose the $60 committed.
The quoted contract price can indicate the market’s approximate implied probability, but it should not be treated as a reliable forecast on its own. Thin liquidity, trading costs, and market sentiment can all affect prices.
Prediction Markets vs. Sportsbooks
Traditional sportsbooks generally offer odds established by an operator, incorporating a betting margin.
Prediction market exchanges allow traders to buy and sell contracts, with prices reflecting orders and available liquidity. Trading fees and bid-ask spreads can influence the effective cost.
Neither model automatically offers better value.
For example, a sportsbook offering -110 odds requires a bettor to win approximately 52.38% of equivalent wagers to break even. A prediction exchange may display a seemingly more attractive price, but the comparison is incomplete until trading fees and execution costs are included.
Which Prediction Market Platforms Should You Compare?
Kalshi: An event-contract exchange covering sports, economics, politics, and other subjects.
Polymarket US: A U.S.-regulated prediction-market offering that must be distinguished from Polymarket’s international platform.
DraftKings Predictions, FanDuel Predicts, and Robinhood: Additional platforms worth comparing for product availability, costs, liquidity, and market selection.
Are Prediction Markets Legal Across the USA?
Prediction market regulation remains an evolving issue.
Certain exchanges operate under federal Commodity Futures Trading Commission oversight. However, disputes continue over the relationship between federal commodities regulation and state gambling laws, particularly for sports contracts.
Being able to register an account does not necessarily mean that every type of contract is available in your state.
Before trading, verify the platform’s current eligibility rules, contract-specific restrictions, fees, and settlement procedures.

Where Are Online Casinos Legal in the USA?
As of October 2026, seven states have operational regulated real-money online casino markets:
Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island, and West Virginia.
Maine became the eighth state to authorize online casino gaming in 2026, but its regulated market has not yet launched.
This distinction matters. A state may have passed legislation without having licensed operators accepting real-money casino wagers.
In states such as New Jersey, several licensed casino platforms compete for customers. These include FanDuel Casino, Hard Rock Bet Casino, and Betinia.
Before registering, consider the operator’s authorization, games, payment methods, withdrawal policies, and any conditions attached to welcome promotions.
A larger advertised bonus does not necessarily represent better value, particularly when wagering requirements or eligible-game restrictions apply.
Legal Sports Betting in the USA
The U.S. Supreme Court overturned the federal Professional and Amateur Sports Protection Act (PASPA) in 2018, allowing states to introduce their own sports betting frameworks.
By October 2026, 39 states and Washington, D.C. had authorized sports betting in some form.
Missouri was the latest state to launch regulated sports wagering, beginning operations on December 1, 2025.
However, legal sports betting does not always mean statewide mobile access. Some jurisdictions permit wagering only at licensed retail locations or within designated areas.
What Makes a Sportsbook Worth Comparing?
Betting promotions attract attention, but they are only one factor.
Sportsbook evaluations should consider:
- The actual odds and margins offered on comparable events.
- Which sports, leagues, and betting markets are available.
- App functionality, live betting, and cash-out conditions.
- Deposit and withdrawal options.
- Licensing, customer support, and responsible gambling controls.
Our state guides help identify which sportsbooks and betting formats are available in each jurisdiction.
Horse Racing and Racing-Powered Games
Horse racing occupies a distinctive position in the U.S. betting industry.
Many horse racing platforms use advance-deposit wagering and pari-mutuel betting systems, where participants wager into shared pools rather than accepting fixed odds from a sportsbook.
Providers such as AmWager specialize in traditional racing, while newer platforms are extending the model into different types of real-money gaming.
What Are Racing-Powered Games?
Racing-powered games are casino-style experiences linked to underlying pari-mutuel horse racing wagers.
A game may look similar to a slot machine or other digital casino game, but the mechanism determining the financial outcome differs from the random-number generator used by a conventional online slot.
HorsePlay and LoneStar Bet are examples of platforms associated with this model.
The category remains relatively specialized but is commercially significant.
According to Oregon Racing Commission records, Game Play Network, the company behind HorsePlay, processed approximately $475.7 million in horse racing wagers in 2025.
This figure represents wagering handle, not operator profit.
Racing-powered games should not be described as sweepstakes casinos or conventional online casinos. Their availability and regulatory framework depend on the underlying horse racing wagering arrangements.

How USA.bet Reviews Betting Platforms
USA.bet aims to help readers compare legal betting options using information that goes beyond promotional headlines.
We prioritize regulatory status, state eligibility, fees, product features, payout conditions, and the restrictions applicable to individual operators.
We also consider the differences between betting categories. A sportsbook’s odds margin cannot be directly compared with a casino’s theoretical return to player or a prediction exchange’s trading fees.
Where useful, our guides reference official regulator records, operator terms, and independently published industry data.
We distinguish factual information from editorial assessments and identify commercial relationships. We do not treat promotional value as the sole measure of an operator’s quality.
Frequently Asked Questions
Is online betting legal throughout the United States?
No. Gambling laws vary by state and product. Sports betting is more widely available than regulated online casinos, while horse racing and prediction markets follow different rules.
Are prediction markets the same as online sportsbooks?
No. Prediction market exchanges facilitate trading in event contracts, while sportsbooks generally accept wagers at quoted odds. Pricing, regulatory oversight, settlement procedures, and consumer protections may differ.
Can I use an online casino from another state?
You generally must be physically present in a state where the casino is authorized to accept real-money wagers. Geolocation checks are commonly used to enforce these restrictions.
Are racing-powered games available without legal online casinos?
They may be available in certain jurisdictions that do not authorize conventional online casino gaming, but access is determined by the relevant horse racing laws and operator permissions. Availability is not universal.
How does USA.bet earn revenue?
USA.bet may earn affiliate commissions when readers register or undertake qualifying activity through selected commercial partner links. We also cover operators and markets without a commercial relationship to provide broader information about the U.S. betting industry.
Gambling and event-contract trading carry financial risks. Participate only when legally eligible, review the applicable terms, and never assume that a bonus or market position will produce a profit. For U.S. gambling-related assistance, visit 1-800-GAMBLER.
