Volume vs. Value: How Sportsbooks Split the Missouri Market

While Missouri’s macro sports betting market achieved immediate stability over its first half-year, the internal battle among individual operators revealed radically different corporate philosophies. In an industry where everyone targets the same sports fans, operators chose vastly different paths to find profitability.

Official figures from the Missouri Gaming Commission covering the first six months of mobile operations (December 2025 through May 2026) illustrate that market share is only one part of the story. The real narrative lies in the relationship between betting volume, promotional investment, average ticket size, and ultimate operational efficiency.

Missouri’s 6-Month Mobile Leaderboard & Operating Efficiency

Over the state’s initial six months, mobile sportsbooks accepted a total of $2.039 billion in wagers across 81,785,284 individual online bet slips. Statewide, operators spent a collective $199.39 million in site credits to clear $79.20 million in net Adjusted Gross Revenue (AGR) – meaning the mobile market as a whole spent $2.52 in promotions for every $1.00 it kept in net earnings.

However, corporate efficiency varied wildly across the competitive landscape.

6-Month Mobile Performance Metrics (Dec 2025 – May 2026)

1. The Duopoly: FanDuel Spent Big, but DraftKings Spent Smart

DraftKings and FanDuel comfortably secured their status as the market’s twin titans, capturing a combined 72.08% of all online wagers. Both surrendered early profitability to build user bases, pouring a collective $101.7 million into free play during December 2025 alone.

However, as highlighted in the operating efficiency ranking, the six-month efficiency totals reveal that DraftKings ran a significantly tighter financial ship.

FanDuel threw a market-leading $84.45 million at players, but generated $27.95 million in net AGR, translating to a heavy 3.02x promo-to-AGR ratio ($3.02 in promotional credits for every dollar kept). DraftKings spent $15 million less on promos ($69.40 million) yet collected more net earnings ($33.38 million). This brought DraftKings’ acquisition cost down to 2.08x, proving that higher promotional volume does not automatically yield superior corporate returns.

2. The Ticket Paradox: Parlay Factories vs. Casino VIP Havens

The commission’s wager logs highlight a stark divergence in player profile and marketing efficiency between mass-market apps and legacy casino operators.

The Casual Mass Market (FanDuel & DraftKings)

Despite dominating handle, FanDuel and DraftKings reported the lowest average bet slip sizes among traditional operators, sitting at $22.22 and $23.29, respectively. Their platforms act as digital volume drivers, funneling casual fans into low-stake, high-margin Same Game Parlays (SGPs). Millions of $5 and $10 tickets keep average stakes low, but the massive house edge on parlays allows both to sustain high promotional spend.

The Retail VIP Migration (Caesars & BetMGM)

In contrast, Caesars ($58.14 average bet) and BetMGM ($55.72 average bet) logged ticket sizes nearly triple those of the duopoly.

Because both operators converted existing high-net-worth table game and slot players from their physical Missouri casinos via unified loyalty networks, they avoided expensive digital ad battles for casual bettors. This strategy paid off in pure operational efficiency: Caesars ranked #2 statewide with a lean 1.11x cost ratio ($1.11 in promotions for every $1.00 of AGR earned), while BetMGM took #3 at 1.35x. They handled far fewer total tickets, but their margins were among the cleanest in the state.

3. The High Cost of Market Entry (bet365 & Fanatics)

Securing market position behind the duopoly came at an eye-watering price. Globally recognized bet365 aggressively grabbed the bronze medal with an 8.83% market share ($180.1 million handle), but did so by deploying $25.73 million in promos, posting a 3.61x ratio on an average ticket size of $20.13.

Even more extreme was Fanatics Sportsbook. Despite generating a solid $133.1 million handle, Fanatics spent $8.71 million in promotions while securing just $1.65 million in net AGR. That yielded an unsustainable market-high ratio of 5.29x ($5.29 spent for every single dollar retained), demonstrating how difficult it is for new mobile platforms to achieve near-term promo efficiency in a pre-educated market.

4. Structural Purism: Circa Sports’ Zero-Promo Strategy

Las Vegas-based Circa Sports provided the ultimate contrast to Missouri’s promotional war, topping the efficiency ranking by reporting $0.00 in promotional free play across the entire six-month span.

By completely eliminating sign-up bonuses, Circa naturally bypassed the casual mass market, claiming a modest 0.47% share ($9.52 million handle). But while other challenger brands bled millions in site credits, Circa generated $434,812 in pure, organic AGR at a perfect cost ratio of 0.00x.

The proof of Circa’s unique model lies in what its users bet on. While the Parlay category was the undisputed volume king for almost every sportsbook in the state (with only occasional spikes in “Other” wagers for DraftKings and Fanatics), parlays were never the most popular category for Circa in any month.

Operating as a sharp, high-limit book, Circa’s wager volume organically tracked the actual sports calendar:

• December: Volume centered on straight Football wagers.

• January – March: High-rolling hoops bettors made Basketball the top category.

• April – May: Volume seamlessly transitioned to straight Baseball bets.

With an average bet slip of $178.84 – nearly eight times larger than FanDuel’s casual baseline – Circa proved that a disciplined sportsbook can skip the promo bloodbath entirely and run a profitable business on the backs of dedicated sports purists.
