Best Sports Betting Sites: 9 Legal Sportsbooks and Promo Codes
There are many similarities between prediction markets and traditional sports betting markets. You should be wary of these brands, as they do not offer the same protections or guarantees as the top-rated sports betting sites on this page. However, some offshore online sportsbooks still accept customers from the United States. Most sites also provide odds on rugby union, rugby league, horse racing, greyhounds, Formula 1, NASCAR, darts, snooker, pool, table tennis, volleyball, and cycling. Remember, responsible gambling is critical to maintaining the enjoyment of sports betting while ensuring your well-being and financial security. Safe and responsible betting ensures a positive and enjoyable betting experience.

With optimism that prediction markets will remain federally legal in their current form, plenty of companies are joining the space. BetMGM and Caesars, notable sportsbooks that are also under parent companies with massive brick-and-mortar casino businesses, have not yet entered prediction markets. Because the companies running the prediction markets don’t care who wins, the companies aren’t exposed to the risk of users beating them to news and information. FanDuel Predicts is expected to expand to other states in 2026, but did say in a press release that “As new states legalize online sports betting, FanDuel will cease offering sports event contracts in those states.” That federal regulation has been essential to the sudden growth of prediction markets because that means they can go live in all states, including those where traditional mobile sports betting remains illegal, such as California and Texas. Even if it’s not going to be the highest-volume market or highest revenue-producing market, if we think there is interesting or pertinent information to be gleaned from it, we’ll list it.

In 2020, the top three operators (FanDuel, DraftKings, BetMGM) held approximately 78% of the market combined. BetMGM maintains a solid third-place position in the US sports betting market with approximately 14% of national gross gaming revenue. DraftKings has leveraged this proprietary stack to offer innovative features faster, including live streaming, social betting, and micro-betting on individual plays. DraftKings challenges FanDuel most strongly in Ohio, where DraftKings holds a slight edge at 38% vs 36%, and in Colorado, where the two are nearly tied at 35% and 33% respectively. With an estimated $2.7 billion in 2025 revenue and 2026 guidance of $3.1–3.2 billion, BetMGM leverages the MGM Rewards loyalty ecosystem and iconic brand recognition to maintain its position, particularly among traditional casino customers who also bet on sports.
