Sportsbook Market Making: The New Prediction Markets Battleground

For sportsbooks, prediction markets are no longer just a question of product expansion. They are becoming a test of whether operators can run the machinery behind an exchange: liquidity provision, execution quality and exposure management.

In traditional sports betting, operators compete on product depth, margin, brand and retention. In prediction markets, they also need enough counterparties to keep contracts tradable at credible prices.

As iGaming Business reported, DraftKings and FanDuel are already looking beyond consumer-facing prediction products and into the mechanics behind them. DraftKings CEO Jason Robins told analysts the company could have “one of the top two or three market-makers” for sports contracts. That ambition shows where the next layer of competition may sit.

Prediction Markets Need Liquidity To Function

A sportsbook solves liquidity by acting as the counterparty: the customer places a wager and the bookmaker accepts the risk, subject to its limits and trading policy.

Prediction markets work differently. Users need participants willing to buy and sell contracts continuously. Without them, spreads widen, execution weakens and activity slows. Market makers provide that function by quoting both sides of a contract and absorbing temporary imbalances in supply and demand.

Why Sportsbooks Have A Market-Making Edge

Sportsbooks bring trading infrastructure that many exchange-native entrants still need to build.

They already price fast-moving markets, manage exposure across related outcomes, monitor informed action and react to live information. Those skills matter because event contracts also depend on probability modelling under uncertainty.

The strongest edge appears in in-play markets and correlation pricing. Live sports move quickly, while parlays and same-game parlays require models that understand how outcomes interact. If prediction markets expand into combination contracts, that expertise becomes more valuable.

DraftKings Is Building A Trading Stack

DraftKings is treating prediction markets as infrastructure, not just another product tab.

The company’s acquisition of Railbird gives it a clearer route into prediction market infrastructure. In its announcement, DraftKings said the deal was intended to support future growth in prediction markets, while noting that changes in online gaming and prediction market regulation could affect the opportunity.

Its 2026 Investor Day materials positioned prediction markets within a wider platform strategy, including exchange capabilities, proprietary pricing, trading intelligence and parlay-style technology.

The economic logic is clear. If DraftKings owns more of the trading stack, it can capture value from spread economics, order flow and product design instead of simply sending customer activity to a third-party venue.

FanDuel Is Monetizing Pricing Expertise

Flutter is approaching the same opportunity through distribution and pricing.

FanDuel Predicts extends the company’s reach into jurisdictions where traditional online sportsbooks are unavailable. Flutter’s said its FanDuel “One App” delivers sportsbook products in sportsbook states and prediction market products in non-sportsbook states.

Flutter was also explicit about the commercial angle. The company said its proprietary pricing could “unlock a significant market-making opportunity” and that it began trialing market-making services on a major third-party prediction market platform in April 2026.

That detail points beyond FanDuel’s own app. For operators with advanced trading teams, pricing itself can become a service sold to external venues.

Sports Market Making Is Not Traditional Financial Market Making

The biggest mistake would be to treat sports market making like equity or futures market making.

Many financial market makers can hedge through underlying assets, correlated instruments or related markets. Sports event contracts rarely offer that kind of clean offset. There is no asset that fully hedges exposure to the Super Bowl, a Grand Slam final or an NBA playoff series.

That puts sports market making somewhere between exchange-style liquidity provision and bookmaking. Firms must quote prices while managing informed traders, concentrated positions, event volatility and exposure that may remain until settlement.

The business is therefore not only about earning a spread. It also requires underwriting event risk correctly.

Combos And Parlays Will Determine The Margin Opportunity

Prediction markets can generate volume through simple event contracts. Matching sportsbook-level economics is harder.

Sportsbooks have historically earned strong margins from parlays because correlated outcomes are difficult to price. Prediction markets face a similar test: single-event contracts can become commoditized when venues rely on the same public probabilities, data feeds and market signals, while combination contracts require stronger correlation models.

That helps explain DraftKings’ focus on combo-style products. The opportunity is not more contracts for its own sake, but products with better economics than standalone event markets.

Regulation Remains Unresolved

The commercial opportunity is clearer than the regulatory framework.

In March 2026, the CFTC issued a prediction markets advisory and opened a rulemaking process on event contract derivatives. Many state gaming regulators and industry groups argue that sports event contracts resemble sports betting and should not bypass state and tribal gambling frameworks.

Legal analysis from Holland & Knight describes the issue as an ongoing jurisdictional conflict, not a settled question.

For operators, that uncertainty affects launch strategy, contract design, state availability, partner selection and compliance costs. Prop-style contracts add another pressure point because individual participants can have more influence over outcomes, raising integrity concerns around athletes, officials and other insiders.

What Operators Should Take From 2026

Market making gives operators four strategic choices: build, buy, partner or outsource.

Building in-house gives the operator more control over execution quality and economics, but requires capital, trading talent, stronger models and risk controls. Buying infrastructure, as DraftKings did with Railbird, can shorten the path but still leaves integration and regulatory exposure. Partnering or outsourcing may be faster, but it limits how much value the operator captures from the trading layer.

That is the management decision behind the prediction markets race. Operators are not only choosing whether to launch event contracts. They are deciding which parts of the exchange economy they want to own.

For DraftKings, FanDuel and the next wave of entrants, prediction markets now sit beyond the product roadmap. The real question is whether a sportsbook wants to be a storefront for event contracts or part of the machinery that makes those contracts work.
