Highlights
FanDuel, DraftKings, BetMGM, and Caesars are unequivocal leaders in US gambling brands offering both casino and sports betting.
Generous promotions are a highlight at US one-stop platforms, ranging from welcome bonuses to bonus bets, casino spins, and more.
Social sportsbooks and casinos are an excellent alternative for users in restricted areas.
Traditionally, casino or sports betting had you choosing one platform over another, but that's no longer the case, a remnant of the past, as you'd have it. Today, US players can get a taste of the two-in-one.
Throughout this guide, I'll walk you through the top US gambling brands offering a merger of the two worlds, i.e., both casino and sports betting, with honorable mentions like FanDuel, DraftKings, BetMGM, and Caesars. We'll also examine what makes them special, their exclusive bonuses, and how to get started. Let's begin!

Is Sports Betting and Casino Gaming Legal in the US?
The short answer is yes, sports betting and casino gaming are legal in the US. However, the legality varies by state. The 2018 Supreme Court ruling overturning PASPA (the Professional and Amateur Sports Protection Act of 1992), i.e., declared it unconstitutional, allowed states to legalize sports betting. Fast forward to today, and the legality of sports betting is solely dependent on the state.
As of July 2025, we've 38+ states legalizing sports betting (or some form of it), including Washington, D.C., and Puerto Rico. Comparatively, the legalization of traditional online casinos has faced slower adoption than, say, the sports betting counterpart. Looking in, only seven states, i.e., Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island, and West Virginia, allow real-money online casinos.
Still, social casinos are bridging the gap with sweeps model that is legal in most of the US. Granted, legality, like in sports betting, is determined on a state-by-state basis, and it's worth going over the T&Cs to determine if your region is restricted.

Our list wouldn't be complete without Caesars, an industry leader with ties to the iconic Caesars Palace that's long been synonymous with casino and gambling. The grandiose is well reflected online, e.g., with the one-of-a-kind rewards program (Caesars Rewards), where you can redeem your accumulated rewards credits at 50+ destinations.
On the finer details, Caesars users will like the sports welcome bonus that credits up to 10x 100% profit boosts, each going up to $2,500. You heard that right, they dub this the "Bet $1, Double Your Winnings Your Next 10 Bets," and it's one that arguably catapults it to a top contender on this list. Embellishing aside, the sportsbook is very solid! All the major US sports are covered, with the list extending to popular global sports.
