Sports betting has transformed from ancient gladiator wagers to a high-tech, multi-billion-dollar global industry—dominated today by powerhouse sportsbooks in the United States and a rapidly growing legal market in Canada. In the U.S., legal operators handled nearly $150 billion in bets in 2024, while Ontario’s competitive iGaming launch saw CAD $17 billion wagered in its first year. From the NFL to the PGA Tour, and from live in-play wagering to strategic golf betting, fans on both sides of the border are fueling unprecedented growth in one of the fastest-expanding entertainment sectors in the world.
From Ancient Wagers to Bookmakers
Betting has long been embedded in human culture. Records suggest that wagering existed many tens—or even hundreds—of years ago. In Ancient Rome, spectators placed bets on gladiator fights. Initially, winning bets were often settled through conventional wagers, paid in cash—but collecting on losses could be tricky. Mediators emerged to enforce fairness, collecting a small fee (a margin) and acting much like early bookmakers or tote operators—ensuring bets were honored with integrity.
What Is Modern Sports Betting?
Today, sports betting refers to the act of placing wagers on the outcomes of sporting events—from football and horse racing to MMA. Bettors may look up MMA betting tips to inform their wagers. A bookmaker (or sportsbook) is a commercial entity that offers odds on event outcomes. If your bet wins, you collect your money plus any applicable bonus; if not—you lose only your stake.
Professional bookmakers employ odds compilers who assess event probabilities via sophisticated models. Many platforms now provide expert insights and detailed odds, offering a reliable and efficient wagering experience.
Live, or in-game, betting has transformed sports like golf. Major tours like the PGA and LPGA now operate globally year-round, with bettors placing wagers mid-round at dynamically updated odds.
Still, betting isn’t for everyone. It takes expertise to win consistently; many bettors end up losing. That’s why trust in the platform matters—vetted reviews help players find trustworthy sportsbooks and avoid scams.
Wagers can span different timeframes—from long-term predictions to minute-by-minute live bets. Like financial markets, odds shift continually, and success often depends on intuition, especially in fast-paced, live-betting formats.
U.S. Sports Betting Market: Scale & Growth
Total Size & Revenue
- In 2024, U.S. sportsbooks took in approximately $148 billion in bets (“handle”) and generated $13.71 billion in revenue, a 23–24% year-over-year jump from 2023.
- Since the 2018 repeal of PASPA, regulated operators have amassed over $500 billion in total wagers, yielding nearly $50 billion in gross revenue.
- As of May 2025, legal sportsbooks had processed around $520 billion in total bets.
Market Forecast
- The broader U.S. sports betting market was valued at about $17.94 billion in revenue in 2024 and is projected to reach $19.76 billion in 2025, expanding at a 10.9% CAGR toward $33.18 billion by 2030.
Retail vs. Online
- In May 2025, combined land-based gaming (casinos plus retail sports betting) generated $4.50 billion in revenue. Retail sports betting alone surged 33.8%, while online sports betting grew 23.5%, totaling $2.21 billion in revenue.
Industry Players & Market Dynamics
- The industry is dominated by DraftKings and FanDuel (owned by Flutter Entertainment), collectively holding about 80% of the U.S. market.
- Leading companies have seen volatile profit forecasts. In Spring 2025, both trimmed earnings guidance following unexpected bettor success during March Madness. DraftKings cut its sales outlook by $200 million to $6.4 billion, and Flutter reduced its U.S. EBITDA forecast by $180 million to $1.13 billion.
- DraftKings’ Q2 2025 results showed robust growth: revenue rose 36.9% to $1.51 billion and net income soared 147.5% to $157.9 million. Yet, monthly unique players fell short of expectations.
- In Q2, Flutter (FanDuel’s parent) posted $4.19 billion in revenue—up 16%—and profits rose 25% to $919 million. U.S. revenue, mostly driven by FanDuel, increased 17%.
Public Health & Regulation
- Since legalization expanded from one state to 38 (plus D.C.), online betting has surged—from $4.9 billion to $121 billion in annual wagers—and interest in gambling addiction has increased. Search queries for help have grown 23%, especially in states like Illinois and Pennsylvania.
- VIP loyalty programs—offering personalized perks to high-spending bettors—face growing criticism. Regulators and lawmakers are pushing back, citing exploitation of vulnerable individuals. The proposed SAFE Bet Act seeks to ban such programs and enforce stronger responsible-gambling safeguards.
Golf Betting for Canadian Fans
Golf Betting for Canadian fans, golf betting has become a growing pastime—especially with legalized single-event sports wagering in provinces like Ontario, Alberta, and British Columbia. The PGA Tour, which hosts major events across North America, often includes stops just over the border, making it easy for Canadian bettors to follow and wager on top players.
Why It’s Popular in Canada:
- Year-Round Action: With tournaments running almost every week, there’s always an event to bet on.
- Live Betting Appeal: Just as in the U.S., Canadians can place in-play wagers as the tournament unfolds, adjusting their bets based on changing conditions or player momentum.
- Major Events Drive Interest: The Masters, the U.S. Open, The Open Championship, and the RBC Canadian Open are especially big draws for betting.
Online sportsbooks in Canada offer markets on everything from outright winners to top-10 finishes, head-to-head matchups, and even prop bets like “Will there be a hole-in-one?” The sport’s slower pace allows fans to make strategic, mid-round decisions—perfect for those who enjoy analyzing form, weather, and course conditions.
U.S. vs. Canadian Sports Betting Markets
While both countries share cultural enthusiasm for sports betting, their markets differ in size, structure, and regulation.
Market Size
- United States: Nearly $150 billion in annual legal wagers and $13–14 billion in sportsbook revenue (2024 figures).
- Canada: The legal market is smaller but growing. Ontario, the largest province by population, saw over CAD $17 billion wagered in its first year of regulated online betting, generating CAD $1.4 billion in revenue.
Regulatory Approach
- U.S.: Regulation is state-by-state. Some states allow only retail sportsbooks, others both online and retail, and tax rates vary widely.
- Canada: Provinces control regulation. Ontario has adopted a competitive licensing model with dozens of private operators, while some provinces keep a monopoly via government-run platforms.
Sports Popularity
- U.S.: NFL, NBA, MLB, college sports, and UFC dominate betting volumes.
- Canada: NHL hockey is king, but golf, soccer, and basketball have strong followings—particularly during major tournaments.
Cross-Border Influence
- Many Canadian bettors follow U.S. leagues closely, and some travel to U.S. states to place retail bets at casinos or sportsbooks during major events like the Super Bowl or March Madness.
Bringing It All Together
Sports betting has journeyed from ancient gladiatorial wagers mediated by early bookmakers to today’s high-speed, digitally driven market.

Both retail and online channels contribute significantly, with digital platforms showing especially strong momentum.
Canada is building a competitive sports betting industry of its own—particularly in Ontario—and golf betting is a fast-growing segment north of the border. The similarities in fan interest, combined with differing regulations, make the U.S. and Canadian markets fascinating to watch as they mature and adapt.
