The phone is no longer a distraction from the game. It is part of the routine. A WSC Sports summary of Deloitte research says around 77% of US sports fans do at least one extra game-related activity while watching, including checking stats, using social media, watching another game, playing fantasy sports and betting. Whether you are tracking injuries, following live data or opening betway during a break, the second screen now sits alongside the main event.
The same research says 71% of fans still rank live sporting events as their favorite type of sports content. The pull of live sports is still strong; what has changed is the way you follow them. Betting grew alongside habits fans already had, especially checking updates, reacting to momentum and moving between apps while the game is still live.
The Couch Got Smarter
Watching sports at home used to be simpler. You turned on the game, argued about a call and waited for halftime to look anything up.
Now the second screen fills in the gaps while the action unfolds. You can check a pitcher’s recent form, follow another game during a break, see what fans are saying in real time or track how one play changed the contest. For most home viewers, that is standard behavior rather than a niche habit.
That helps explain why betting felt familiar so quickly. It did not arrive as a separate routine. It slotted into one that already ran on fast information and quick reactions. If you are already checking live stats on your phone, opening a betting app feels like another step in the same flow.
There is a simple benefit as well. You no longer need to leave the game to find context. Your second screen can bring together data, commentary, community and betting options while the game is still moving, which makes the experience feel fuller and easier to follow.
The Real Stadium Is in Your Pocket
The numbers show how strongly mobile access has shaped this habit. The American Gaming Association says US commercial sports betting revenue reached $13.78 billion in 2024, up 24.8% from 2023, while Americans legally wagered $149.90 billion on sports that year. ESPN later reported AGA figures showing sportsbook revenue climbed to a record $16.96 billion in 2025 on $166.94 billion in legal wagers.
By the end of 2024, legal mobile sports betting was available across much of the country. That changed the rhythm of betting for US fans. You did not need to plan a separate outing or treat betting as a special event. You could place a wager from the couch, at the bar or in the backyard while keeping up with the game in real time.
AGA’s commercial gaming tracker later reported $1.37 billion in sportsbook revenue for May 2026 alone, with $12.10 billion wagered during that month. Those figures point in the same direction. The phone was already central to game day, and sports betting grew because it fit that habit cleanly.
AGA commercial totals do not capture every legal betting dollar in the country. They exclude some tribal sportsbook revenue, including Florida’s tribal mobile betting from those commercial figures. The headline numbers are strong, and they still lean conservative.
Odds on a Screen
Access explains part of the growth. Engagement explains the rest.
WSC Sports’ summary of Deloitte’s fan research says bettors are more engaged than non-bettors and are more likely to attend games in person, buy merchandise or memorabilia and pay for a sports streaming service. That does not mean every engaged fan bets. It does suggest that betting often sits within a broader pattern of active fandom.
Many sports apps are no longer built around one task. They are designed to keep you close to the flow of the event. Live stats, alerts, alternate feeds, streaming access and betting options all serve the same purpose: helping you follow the game with more context and more control.
You can see the same pull across the wider sports market. Tools such as richer live data feeds reflect growing demand for faster updates and deeper context during live competition. Betting apps benefit from that demand because they sit in the same second-screen environment.
The New Game-Day Habit
For many of us, the second screen is no longer a side activity. It is woven into the way games are followed, discussed and enjoyed. Sports betting found its place there because it matches habits that were already firmly in place: checking stats, reacting in real time and looking for more context before the next play.
The growth figures support that pattern. Revenue rose from $13.78 billion in 2024 to $16.96 billion in 2025, according to AGA data reported by the association and ESPN, and the momentum carried into 2026.
Your phone is no longer pulling you away from the game. For a growing share of fans, it helps bring the game into focus. In that setting, sports betting feels like a natural part of modern game day.
