Bookmakers are increasingly turning to market-making strategies to drive growth in the evolving sports betting industry. As technology advances and prediction markets gain traction, operators are seeking innovative ways to enhance liquidity and profitability beyond traditional sportsbook models.
The integration of financial market concepts into wagering is creating new opportunities for bookmakers, particularly as prediction markets—where participants trade contracts based on event outcomes—become more popular. These platforms depend on effective market-making to ensure continuous trading and fair pricing, a role that bookmakers with advanced modeling capabilities are well-positioned to fill.
Prediction Markets and the Role of Market-Makers
Unlike conventional sportsbooks where the house acts as the counterparty to all bets, prediction markets operate more like financial exchanges, relying on market-makers to facilitate trades between buyers and sellers. Early versions, such as Betfair in the UK, sometimes struggled with liquidity issues, limiting their growth potential. However, the current wave of prediction platforms is attracting major betting operators who see market-making as a pathway to new revenue streams.
Industry leaders like DraftKings and FanDuel have publicly highlighted their ambitions in market-making. DraftKings CEO Jason Robins recently stated that their expertise positions them among the top market-makers for sports contracts globally. Similarly, Flutter’s Peter Jackson confirmed that FanDuel is actively investing in in-house market-making capabilities. Although both companies have experienced recent stock declines, largely due to capital expenditures in this area, the long-term profitability potential remains a compelling draw.
Academic Research Sheds Light on Best Practices
The growing interest in market-making was a focal point at the 19th International Conference on Gambling and Risk Taking, hosted by UNLV. Researchers, including PhD candidate Shivam Sharma, presented new insights into market-making strategies and risk management, using examples from Major League Baseball prediction contracts. Sharma emphasized the importance of liquidity provision, intelligent limit order placement, and managing the bid-ask spread as core elements of successful market-making.
According to Sharma, unlike stock trading where payout structures are fixed, prediction market contracts are directly influenced by event-specific probabilities, requiring unique mathematical modeling. While some research exists on automated market-makers, comprehensive mathematical frameworks for sports-based prediction markets are still emerging.
Risk Management and Inventory Control
Effective risk management is central to market-making, as bookmakers must carefully monitor their exposure to ensure profitability. Inventory control—limiting the volume of outstanding contracts—is crucial to mitigate risks associated with price fluctuations and unpredictable event outcomes. Sharma’s research highlights the need for strategic implementation, particularly around key periods of a sporting event rather than maintaining constant exposure throughout.
This approach aligns with current sportsbook practices, where operators focus on uptime and live market availability. For example, data from Eilers & Krejcik Gaming shows that major US sportsbooks maintained over 65% uptime for college football games, with DraftKings leading at 86%. Overround metrics, which measure the operator’s expected return, also indicate healthy margins for well-managed books.
Future Outlook for Bookmakers in Market-Making
Bookmakers see significant promise in market-making as both a revenue generator and a strategic differentiator. DraftKings’ Robins has expressed confidence that market-making will deliver strong results with modest capital requirements, providing a new stream of profitability as prediction markets mature.
As the boundaries between finance and sports betting continue to blur, operators who can master market-making strategies and advanced risk controls are poised to lead the next phase of industry growth.
