Sports betting is a convenience that has rapidly become a norm for many, thanks to its widespread legalization and popularity across the United States.
You might think online casino games—known as iGaming—would follow the same trajectory, offering the same easy access to games like slots and poker. However, the path to full legalization for iGaming has been noticeably slower and more complicated.
Unlike sports betting, which saw quick legislative changes post-2018, online casinos encounter a web of challenges. These include regulatory issues, strong opposition from traditional gambling entities, and societal concerns about gambling addiction.
So, let’s take a closer look at why, despite the appeal and financial potential of iGaming, its acceptance and growth have lagged behind the fast-paced rise of sports betting.
The 2018 U.S. Supreme Court decision to overturn the Professional and Amateur Sports Protection Act (PASPA) was pivotal.
This act had previously restricted sports betting primarily to Nevada. Since the decision, 38–40 states have legalized sports betting, with 31–32 offering mobile/online options. The rapid legalization has led to significant tax revenue, such as over $1.8 billion in a recent fiscal year, along with partnerships with major sports leagues.
Sports betting is seen as skill-based, aligning with America’s sports culture, making it a low-barrier expansion. In contrast, online casino games—including slots, blackjack, roulette, and other house-banked games—lacked any comparable federal trigger or cultural “halo.”
Even in states that quickly adopted sports betting, expanding to full iGaming has faced sustained resistance, resulting in only eight states currently offering regulated real-money online casinos. The states with legalized online casinos include:Legalizing online casinos in the United States is complex, with many challenges to overcome. However, with clever solutions and robust regulations, there is hope that online casinos can one day achieve the same level of acceptance as sports betting.
iGaming, or online casinos, faces several challenges that slow its widespread acceptance.
Unlike the rapid spread of sports betting after a key federal decision, legalizing online casinos requires balancing economic benefits with the real risks involved.
The future of online casinos (iGaming) in the United States is expected to grow slowly, state by state, instead of expanding quickly across the country as sports betting did after the 2018 PASPA decision. With only eight states having legalized online casinos so far, there is a lot of room to add more.
This number is much smaller compared to the roughly 39 states (plus D.C.) that allow legal sports betting. The spread of online casinos will likely be slow, driven by the need for more money but held back by politics, opposition from some groups, and careful decision-making.
Experts describe 2026 as a quiet year for new online casino approvals. Although there are bills in states like Massachusetts, Virginia, and New York, not many of them are expected to become law by the end of 2026.
Maine’s recent success was unusual since it focused on tribal interests and passed without the governor’s signature. Many challenges, like concerns during election years, union and labor opposition (particularly in New York), and difficult negotiations, mean most progress will be limited to discussions and planning rather than new laws.
Some predict the next significant changes might not happen until 2027, with only 1 or 2 new states likely to join by then.
Over the next 3–5 years, more states are expected to allow online casinos, potentially increasing the total to 10–12 by 2030.
This growth won’t be as fast as sports betting because online casinos face more resistance and lack a big national push. States like Nebraska, Maryland, Wyoming, Virginia, and Ohio, which already have sports betting, are seen as future candidates for iGaming because it could be a profitable next step.
Existing online casino markets will keep improving and coming up with new ideas, like special apps and games, while also focusing on responsible gaming technology.
The United States will have a mixed map of legal and illegal online gambling, but overall, the industry is growing, with online casinos playing an important role in the gambling industry’s success. More states will likely legalize online casino games, but progress will be slow and careful, depending on state laws, financial needs, and agreements between different groups. Unlike the fast growth of sports betting, the future of online casinos is about steady expansion through careful negotiation.
Success in the current eight states will serve as a strong example for others to follow, but only when revenue potential and risk management are balanced.
