Each year, the NCAA Tournament becomes one of the most important moments in the U.S. sports betting calendar. With more than 60 games played across three weeks and millions of fans following the action, March Madness creates an ideal environment for sportsbooks to attract new users and convert casual sports fans into betting customers.

This year, sportsbooks are projected to handle roughly $4 billion in wagers during the tournament, setting another record and reinforcing the event’s role as one of the most powerful growth drivers in the American betting industry.

But behind the massive betting handle lies something even more important: a fierce competition among sportsbook operators to capture new users. March Madness has effectively become the largest annual customer acquisition opportunity in U.S. sports betting.

For operators such as DraftKings, FanDuel, BetMGM, and Fanatics, the tournament represents a critical moment to expand market share, introduce new bettors to their platforms, and build long-term customer relationships.

Why March Madness Is a Customer Acquisition Engine

Unlike other major sporting events such as the Super Bowl, which generate a single-day surge in betting activity, March Madness unfolds across multiple rounds with games taking place almost daily.

This extended schedule creates several strategic advantages for sportsbooks.

First, the tournament offers continuous betting opportunities, particularly during the opening rounds when dozens of games take place within a short period. New users can engage repeatedly throughout the tournament rather than placing a single wager.

Second, the NCAA Tournament already has a built-in betting culture through bracket pools and office competitions, which naturally introduces millions of casual fans to wagering concepts.

Third, the tournament creates sustained engagement across several weeks, allowing sportsbooks to onboard new customers and encourage repeat betting behavior.

For operators, the primary objective is simple: convert a casual fan filling out a bracket into a long-term sportsbook user.

DraftKings: Turning Bracket Players Into Bettors Through ESPN Integration

DraftKings has taken one of the most strategic approaches to March Madness customer acquisition by integrating directly with ESPN’s massive bracket ecosystem.

Ahead of the tournament, DraftKings launched an account-linking integration with ESPN, allowing fans to connect their DraftKings sportsbook account directly with their ESPN profile. Once linked, users who participate in ESPN’s Tournament Challenge bracket contest can unlock a feature known as “Bet Your Bracket.”

Through this integration, a fan’s bracket selections automatically generate personalized betting opportunities inside the DraftKings sportsbook app. If a user picks a team to advance in their bracket, DraftKings can immediately suggest wagers tied to that prediction, including moneyline bets, futures wagers, and other betting markets.

The strategy essentially converts one of the most popular sports fan activities in America — filling out a bracket — into a direct on-ramp to sports betting.

This approach is particularly powerful because ESPN’s Tournament Challenge attracts millions of participants each year, many of whom are casual fans who have never placed a sportsbook wager before. By connecting bracket picks to betting markets, DraftKings is able to meet fans at the exact moment they are already predicting game outcomes.

DraftKings also offers incentives for users who link accounts, including promotional offers and free trial access to ESPN’s streaming services. Inside the sportsbook app, the “Bet Your Bracket” feature lives as a dedicated tab where users can see betting opportunities tied directly to their bracket predictions.

From an acquisition standpoint, this integration creates a powerful funnel:

1. Fans fill out an ESPN bracket
2. Fans link their ESPN and DraftKings accounts
3. Bracket picks trigger personalized betting suggestions
4. Users place their first wagers tied to their tournament predictions

Instead of relying only on traditional signup bonuses, DraftKings is embedding betting directly into the fan engagement experience.

FanDuel: Simplicity and Parlay-Centric Engagement

FanDuel approaches March Madness acquisition by focusing on simplicity and accessibility for casual bettors.

The operator frequently promotes straightforward signup offers in which new users place a small initial wager and receive bonus bets if the wager wins. These promotions reduce the friction for first-time bettors and encourage them to explore the sportsbook platform.

FanDuel also emphasizes same-game parlays, one of the most popular wagering products in modern sports betting. During the tournament, the operator promotes daily odds boosts, parlay insurance offers, and featured betting combinations tied to high-profile matchups.

Because parlays allow bettors to combine multiple game outcomes into a single wager with potentially larger payouts, they resonate strongly with fans who are already making bracket predictions and trying to forecast tournament results.

FanDuel’s strategy centers on making the betting experience intuitive while guiding users toward highly engaging wager types.

BetMGM: Risk Reduction and High-Value Incentives

BetMGM’s March Madness acquisition strategy focuses on reducing the perceived risk for new bettors while offering larger promotional incentives.

One of the operator’s most common offers during the tournament is first-bet insurance, which allows new users to place an initial wager with the assurance that if the bet loses, they will receive bonus bets equal to the wager amount.

This strategy lowers the psychological barrier for fans who may be hesitant about placing their first sportsbook wager.

BetMGM also leverages the broader MGM Rewards ecosystem, connecting sportsbook promotions with loyalty benefits tied to MGM Resorts properties and entertainment experiences.

By integrating sportsbook activity with a broader loyalty program, BetMGM aims to build deeper relationships with users that extend beyond the betting platform itself.

Fanatics: Leveraging the Sports Commerce Ecosystem

Fanatics represents one of the newest entrants into the U.S. sportsbook market, and its March Madness strategy reflects its unique position within the sports merchandise ecosystem.

The company integrates betting with its FanCash rewards system, allowing users to earn rewards that can be used both for sports wagers and for purchasing licensed team merchandise through the Fanatics retail platform.

This hybrid approach enables Fanatics to connect betting activity with sports fandom in a way that few other operators can replicate.

Because the company already maintains a massive customer database of sports merchandise buyers, Fanatics can cross-promote its sportsbook platform to existing sports fans who may be curious about betting but have not yet opened sportsbook accounts.

This strategy represents a broader shift in the industry toward sports entertainment ecosystems, where betting, merchandise, media content, and fan engagement are increasingly interconnected.

The Promotional Arms Race

Across the industry, March Madness has triggered a promotional competition among sportsbook operators.

To capture new users during the tournament, operators deploy a wide range of incentives, including:

• Bet-and-get bonus promotions
• Deposit matches
• First-bet insurance offers
• Odds boosts tied to tournament games
• Parlay insurance promotions
• Free bracket contests and prediction pools

These promotions serve a clear purpose: lowering the barriers for new users to place their first wager while encouraging them to explore additional betting features.

While these incentives can reduce short-term profitability, sportsbooks view them as investments in long-term customer growth.

Turning Casual Fans Into Long-Term Bettors

For sportsbooks, the true value of March Madness lies in its ability to introduce new users to the betting ecosystem.

Once fans become comfortable with sportsbook platforms during the tournament, operators aim to retain those users through other major sporting events and leagues.

This includes ongoing engagement with markets tied to the NBA, NFL, MLB, and international sports competitions, as well as expanding into new wagering formats such as live betting, player props, and micro-markets.

In many ways, March Madness functions as a massive onboarding funnel for the sports betting industry.

A Defining Moment for the Sports Betting Industry

As the U.S. sports betting market continues to mature, March Madness has become one of the most strategically important events on the calendar.

The tournament combines massive betting volume with widespread fan engagement, creating a unique opportunity for sportsbooks to acquire new customers at scale.

For operators such as DraftKings, FanDuel, BetMGM, and Fanatics, the competition is about far more than who processes the most wagers during the tournament.

The real battle is for millions of new bettors entering the regulated market.

And in an increasingly competitive industry, the operators that capture those customers during March Madness may ultimately define the next phase of growth in U.S. sports betting.
