The Evolution of Sports Betting in the US: From Taboo to Mainstream
By Arslan Saleem July 31, 2025 17:46
Everyone seems to talk about how we’ve changed the way we watch sports, but not enough about how we experience them. Watching the game back in the day was incredibly simple. You’d grab some snacks, order a round of wings, and root for your favorite team. Today? It could mean tracking a same-game parlay, catching up on the stats on a score app, and pacing around the room, hoping your fantasy pick gets a point. While sports fans still enjoy the fun, the food, and the original fan culture, there are so many more layers to the experience, with betting being one of the most significant.
When Betting Was Done Behind Closed Doors
Given how widespread and integrated into daily life sports betting is, it’s hard to remember a time when betting was considered a shady activity. Rather than whipping out your phone and swiping and tapping through potential bets, you simply knew a guy who could handle bets on the down low. In other cases, maybe you discovered an offshore site that claimed they could pay up if you won, but only if you overlooked the potential illegality of things and accepted questionable policies.
Placing a bet was anything but casual. There was always something uncertain and risky about it. And that’s exactly why it carried such a negative stigma among the general public. Sports fans wanted to gamble, but at the time, it meant having to gamble on their personal and financial information. While betting was always a part of sports fandom, it existed on the outer fringes for many decades.
How Fantasy Sports Opened the Door
So how did we go from being so secretive about sports betting to having it become just another casual part of Sunday afternoons? Fantasy football. What began as a fun hobby that superfans participated in to immerse themselves even deeper in the game became a stepping stone toward normalizing sports betting.
For one, it changed how fans watched the game. Instead of having matches be relatively passive, you were now knee-deep in the statistics, matchups, and even games you once thought were insignificant. Being a fan was suddenly a lot more interactive and personal because you had tangible stakes in the game. Strategy and tactics were involved, and there was a constant requirement to manage your lineup and interact with the rest of the league.
Big sports companies caught on, and FanDuel and DraftKings began providing Daily Fantasy Sports (DFS) opportunities. While you could still start your own full-season fantasy football league with friends and family, DFS lets users draft lineups and win real money in daily contests. Because it wasn’t legally considered “gambling” in the guise of the law, it wasn’t considered a problem. DFS was many people’s first taste of earning money using a blend of sports knowledge and luck.
2018: Betting’s Breakthrough Year
After decades of waiting for sports betting to become fully legalized and regulated, 2018 changed everything. The Supreme Court made an influential legal decision in Murphy v. NCAA, letting each state decide its own sports betting laws. Naturally, Nevada was the first state to implement full-scale sports betting, thanks to its massive presence in the US and global gambling ecosystem. From there, it was a domino effect that gradually turned sports betting into a booming, legitimate industry.
Soon enough, the US was experiencing huge cultural and commercial changes. Some would even call it a revolution. Major professional leagues now had the opportunity to partner with sportsbooks, which benefited both parties. Leagues like the NFL, NHL, MLB, and NBA brought legitimacy to betting, while these novel sportsbooks gained branding opportunities, a big fan base, and exclusive data in return. Everyone wanted in on the action, elevating sports betting into a mainstream entertainment experience.
Betting Goes Mainstream
Considering betting has only been accessible since 2018, its evolution is still in play. While sports betting is legal in most states—nearly 40—there’s still plenty of room for others to join the club and for existing members to fine-tune their offerings. With sports betting paired with licensed US gambling websites for casino play, fantasy sports, and score-tracking and analytics apps, wagering has become a natural part of the sports watching experience.
Fans can also find podcasts, YouTube channels, and social media accounts all dedicated to discussing spreads, lines, and parlays. Whether they use it for inspiration, strategy, or to stay in the know, these homegrown communities keep people immersed in betting culture. Then there’s technology. Mobile apps constantly compete with each other by offering lucrative bonuses, competitive odds, and special features like fast cash-out options or unique proposition bets. All these components come together to give fans the richest sports experience possible, making traditional game-watching seem like a far cry.
What’s Ahead for US Bettors
Sports betting is only going to get more sophisticated. As such a nascent industry, there’s endless potential for innovation. Sports betting is set to become legal in more states as the years go on, and this pervasive acceptance could mean a country-wide embrace of betting culture. Ties to technology mean we’re likely to see advances in data analytics, AI, betting formats, and integration with physical stadiums. And bridging the physical nature of sports with the digital is inevitable—after all, nothing beats being there in person. While US sports betting has come a long way from taboo to trending, it’s only just the beginning.
