When a country or state flips the switch on legal sports betting, every licensed operator arrives at the same conclusion at the same time: the first customers you lock in will be the hardest for a competitor to take away.

That logic is plausible. It’s also the reason the opening months of any new market tend to look less like a business launch and more like a bidding war, with a dozen brands throwing money at the same pool of potential bettors.

The Customer Acquisition War in Regulated Sports Betting

The pattern has played out in nearly every jurisdiction that has opened since 2018, and the results are strikingly consistent. A crowded field enters. Most lose money. A small number of survivors end up splitting the vast majority of the revenue.

The mechanics behind that cycle tell you a lot about how modern regulated gambling actually works, and what the industry will probably look like five years from now.

How the Land Grab Starts?

The spending begins before the first bet is even placed. Operators negotiate market access deals, secure state licenses, and build tech infrastructure, all while knowing that their window to grab customers is narrow.

The first six to twelve months after launch are when the largest chunk of casual bettors will try a sportsbook for the first time. After that initial wave, growth slows and the cost of acquiring each new user goes up.

So everybody front-loads their spending. Sign-up bonuses of $200 or more become standard. TV spots run during every major broadcast. Affiliate networks and comparison sites get flooded.

During launch periods, it’s common for comparison pages to be packed with today’s free bets or offers as operators compete to appear at the top of every list a potential bettor might check. The result is a saturation that feels overwhelming to consumers and is punishing for operator balance sheets.

According to industry analysts, the average customer acquisition cost for online sportsbooks now ranges from $250 to $750 per user. In high-tax places, that number can run even higher.

For context, the average lifetime value of a recreational bettor sits somewhere around $1,200 to $1,800 over two to three years.

So the math only works if the operator holds onto that customer long enough to recoup the upfront investment, and that’s a big “if” when every rival is dangling a welcome offer of their own.

Why Most Operators Lose?

The fundamental problem is that sports betting products are hard to differentiate. The odds come from the same data feeds. The bet types are broadly similar across platforms. The user interfaces all pull from the same playbook.

When the product itself doesn’t create loyalty, the only lever left is spending, and the operators with the biggest war chests will always win that game.

This is what makes the shakeout so predictable. Smaller operators, even those backed by recognizable consumer brands, can’t keep up. Fox Bet shut down after barely registering a market share.

PointsBet sold its entire U.S. operation. ESPN Bet was rebranded after its original partnership structure couldn’t sustain the losses.

Meanwhile, the two operators that entered the market with existing daily fantasy sports databases, built during the years before legal betting was even available, had a massive structural advantage.

They already had millions of verified users, payment methods on file, and brand recognition among exactly the audience most likely to place a sports bet. Everyone else was starting from scratch.

Where the Market Share Tends to End Up

Where the Market Share Tends to End Up?

The concentration at the top is stark. By early 2026, the two largest operators in the U.S. controlled somewhere between two-thirds and three-quarters of all online sports betting handle, depending on which data source you use.

The next tier, made up of three or four brands with casino or media backing, splits roughly 20% between them. Everyone else fights over the remainder.

This pattern isn’t unique to the U.S. either. The UK market went through a similar consolidation over the past two decades, and the same dynamic plays out whenever a regulated market matures.

Early entrants with deep pockets and an existing customer base pull ahead, and the gap widens over time as those leaders benefit from lower per-customer marketing costs and better retention rates.

The ad spending figures tell the story clearly. Major operators in the U.S. now report sales and marketing costs of 22% to 26% of revenue, a figure that would look reckless in most industries but has become the accepted cost of doing business in legal betting. Total industry ad spending topped $3.9 billion in 2025 alone.
