Prediction Markets Are Bringing Wall Street’s Trading Model to Sports Betting. Or maybe it’s the other way around: Sports betting is taking on the structure of a financial market. Either way, the implications reach beyond adding another place to back the Chiefs. They change what customers can do with a wager, how companies earn from it, and which businesses get to participate.
The development separates functions traditionally combined within a sportsbook: attracting customers, setting prices, accepting risk and processing transactions. Each becomes a business opportunity for companies from finance, gambling or both.
For bettors, the result is greater flexibility over when to enter and exit a position. It also introduces trading costs and execution decisions that require attention beyond choosing a winner.
From Picking a Winner to Trading a Price
A typical binary sports contract pays $1 if its specified outcome occurs and zero otherwise. Buying at 40 cents means risking 40 cents to earn 60 cents before fees if the contract settles in your favor. The ability to resell that contract changes the calculation.
Consider a hypothetical purchase of 100 contracts at 40 cents each, costing $40. If buyers subsequently offer 65 cents and the holder sells all 100, the proceeds are $65—a $25 profit before fees. The team can eventually lose without affecting that completed sale.
The seller has profited from a price movement rather than from holding a winning wager through settlement. Conversely, someone who correctly anticipates the eventual winner can still lose money by selling during a temporary decline. This resembles equity trading in its mechanics, although the underlying asset is different. A stock represents ownership in a company. A sports event contract expires under specified settlement rules; it provides no ownership interest, earnings or dividends. Its payoff structure more closely resembles a binary option.
The order book is central to the experience. It displays prices and quantities offered by buyers and sellers. A limit order allows customers to specify the highest price they will pay or the lowest price they will accept, but execution depends on a matching order. Market depth therefore affects the price of a transaction. An attractive quote may apply to only a small number of contracts. Buying a larger quantity can require accepting progressively higher prices.
There is also a cost to moving between the buying and selling sides. If contracts are offered at 52 cents while buyers bid 49 cents, purchasing 100 and immediately selling them at that unchanged bid loses $3 before fees. Kalshi separately charges transaction fees, with variations across markets. Comparing a contract with sportsbook odds requires accounting for both the executable price and applicable charges.
These features make early exits possible without guaranteeing an acceptable exit price. They also create an economic incentive for trading platforms: transactions can generate fees regardless of whether an individual customer ultimately profits.
Financial Firms and Bookmakers Compete for Different Parts of the Bet
Professional liquidity providers are an important part of this structure. Their quotes allow customers to transact without waiting for another recreational bettor to take the opposing position. Robinhood’s exchange venture named Susquehanna, an established financial trading firm, as a partner and initial liquidity provider.
Sportsbook operators are entering this business as well. Flutter, FanDuel’s parent, forecast approximately $50 million in market-making revenue for 2026. It identified combination markets as a particular opportunity for its existing pricing and risk-management capabilities. Those capabilities remain relevant because related outcomes require specialized pricing. A quarterback’s passing performance and a receiver’s production are connected. Combining them in a contract does not remove the need to assess that relationship.
This creates a less straightforward competitive picture than prediction platforms simply replacing bookmakers. An established gambling company can supply liquidity within the emerging market structure, earning revenue beyond its own customer-facing sportsbook.
Distribution is changing too. Robinhood announced in September that football contracts would be routed across OG.com, Kalshi and Rothera. Customers using one app can therefore reach multiple underlying exchanges. Different apps may also connect to shared infrastructure, making brand comparisons insufficient to establish whether prices or liquidity are genuinely independent.
Geographic access provides another source of competition. Flutter describes prediction markets as a way to acquire customers ahead of sportsbook regulation in additional states. That strategy remains exposed to litigation over federal and state authority; the NFL backed a request for Supreme Court review in October.
Offshore operators potentially face additional competition wherever these products provide an alternative, although public evidence does not establish the scale of customer migration. Internationally, the model is less novel than the American debate suggests. Britain has had betting exchanges since 2000, and its regulator says typical prediction-market models would generally fall within its betting-intermediary framework.
For bettors, the practical change is a broader set of decisions: purchase price, position size, execution and whether to sell before settlement. Financial-market machinery expands those choices. It does not, by itself, improve the value of the wager.
