The 2026 FIFA World Cup did more than increase soccer wagering across the United States. It accelerated a structural contest between two different models for trading sports outcomes: traditional state-regulated sportsbooks and federally regulated prediction markets.
For American soccer bettors, the difference is no longer theoretical. During the tournament, conventional operators such as FanDuel, DraftKings, BetMGM and Caesars continued offering familiar 1X2 odds, totals, player props and live markets. At the same time, prediction platforms including Kalshi, Polymarket, DraftKings Predictions and FanDuel Predicts presented match outcomes as event contracts that could be bought and sold.
The World Cup gave both systems an ideal test. The expanded tournament featured 104 matches from June 11 through July 19, 2026, creating continuous demand for match-winner, qualification, goal, corner and player-performance markets. By the final, prediction markets had captured a much larger share of U.S. sports activity than they held at the start of the year.
That surge did not make sportsbooks obsolete. It did, however, show that American consumers are becoming comfortable with a second way to express an opinion on a sporting event.
Prediction Markets Gained Ground During the World Cup
The most important World Cup development was the scale of prediction-market growth.
H2 Gambling Capital estimated that prediction markets represented approximately 27% of legal U.S. sports-betting volume during the tournament, compared with about 9% at the beginning of 2026. The estimate was based on public data from the first month of World Cup activity and showed how rapidly event-contract platforms had moved into a market previously dominated by sportsbooks.

Kalshi was the clearest beneficiary. Sports Business Journal reported that the platform generated approximately $27 billion in World Cup trading volume. Its tournament strategy combined extensive contract inventory with marketing agreements involving retired and active soccer figures, including Clint Dempsey, Guillermo Ochoa, Marcelo, Radamel Falcao, Rio Ferdinand, David Villa, Raphaël Varane, Ángel Di María and Lionel Messi.
The platform offered contracts on tournament winners, individual match outcomes, player performances, shots and corner kicks. That market depth allowed Kalshi to resemble a traditional soccer sportsbook even though its legal and commercial structure remained different. (Kalshi’s World Cup trading growth)
The World Cup therefore became a customer-education campaign as much as a sports event. Millions of users were introduced to contract prices that moved between zero and one dollar rather than conventional American or decimal odds.
A contract priced at 60 cents generally suggested that the market assigned the outcome an implied probability near 60%. If the contract settled successfully, it paid one dollar, leaving a gross difference of 40 cents before fees and other costs.
That presentation made prediction markets feel intuitive to users already familiar with financial trading apps. It also allowed customers to sell positions before settlement when liquidity was available, rather than waiting until the match or tournament ended.
Sportsbooks and Prediction Markets Use Different Structures
Traditional sportsbooks and prediction markets can offer exposure to similar events, but they do not operate in the same way.
A sportsbook sets a price and accepts a wager from the customer. The operator effectively stands on the other side of the transaction, manages its total liability and builds a margin into the market. Prices may move as the sportsbook receives wagers, updates its probability model or reacts to changes at competing operators.
A prediction market generally connects buyers and sellers through an exchange. The platform facilitates trading rather than directly taking a directional position against each customer. Contract prices change according to supply, demand and available liquidity.
The Commodity Futures Trading Commission’s explanation of event contracts states that these products are commonly structured as swaps or derivatives tied to the outcome of an event. Many use a yes-or-no format with a fixed payout, although some markets combine several binary contracts to represent multiple possible outcomes.
That distinction changes the language used by each industry.
| Traditional Sportsbook | Prediction Market |
|---|---|
| Customer places a bet | Customer buys or sells a contract |
| Operator posts odds | Exchange displays contract prices |
| Sportsbook manages liability | Buyers and sellers create market exposure |
| Wager usually remains open until settlement | Position may be sold before settlement |
| Regulated primarily by state gaming authorities | Federally regulated event contracts fall under CFTC oversight |
| Operator margin is embedded in odds | Customer costs may include spread and transaction fees |
The two systems can still produce economically similar outcomes. A bettor backing a soccer team at a sportsbook and a trader buying a contract on that team may be expressing almost the same forecast.
The important differences appear in price formation, fees, settlement terms, consumer protections and legal jurisdiction.
Soccer’s 1X2 Format Creates a Special Comparison
Soccer is particularly useful for comparing sportsbooks with prediction markets because a regulation-time match has three possible results: home win, draw or away win.
A conventional sportsbook combines those outcomes in a single 1X2 market. Each result has its own odds, and the total implied probabilities normally exceed 100% because the sportsbook includes a margin.
Prediction exchanges may create three separate yes-or-no contracts covering the same outcomes. The combined prices can also exceed or fall below one dollar at different moments because of bid-ask spreads, uneven liquidity and trading pressure.
The comparison is not always exact. One platform may price the result after 90 minutes, while another may offer a contract on which team advances from a knockout round. Extra time and penalty shootouts can therefore change the meaning of what initially appears to be the same market.
The difference between price and value also remains essential. A popular team can attract heavy demand on either platform, pushing its price beyond what the underlying probability supports. Readers can explore this distinction further in the site’s guide to identifying good betting value.
Prediction-market prices should not automatically be treated as perfect probabilities. A July 2026 study analyzing 23 million sports moneyline trades on Kalshi found that contract calibration changed as settlement approached. The study also found that multi-event contracts were systematically overpriced relative to the combined prices of their individual components, with the gap increasing as more legs were added.
The finding does not mean sportsbook odds are inherently more accurate. It shows that both systems contain pricing friction, customer behavior and structural costs that must be evaluated before a market can be considered efficient.
Traditional Operators Are Joining the Prediction-Market Business
The competition after the World Cup is not simply sportsbooks on one side and independent exchanges on the other. Major betting companies are building prediction products of their own.
DraftKings launched DraftKings Predictions and expanded its catalog through a February 2026 agreement with Crypto.com’s CFTC-regulated derivatives exchange. The agreement added player-specific sports event contracts and established a framework for additional categories. (DraftKings prediction-market expansion)
DraftKings describes its prediction product as a separate platform with a separate wallet from its sportsbook. Its contracts cover sports, finance, politics and other events, while market availability varies by jurisdiction. The company has also identified prediction markets as part of a broader growth strategy that could allow it to reach customers in states without conventional regulated online sports betting.

FanDuel has followed a similar path. FanDuel Predicts operates through FanDuel Prediction Markets LLC, a CFTC-registered futures commission merchant and National Futures Association member.
On June 9, 2026, FanDuel announced that it was expanding its event-contract offering through Crypto.com and OG Prediction Markets. The partnership added more sports, entertainment and combination contracts to the platform.
FanDuel’s official risk disclosure explains that its event contracts are cash-settled derivatives generally presented as yes-or-no options. It also warns that the products may not be appropriate for every customer and that users should evaluate their financial resources and investment objectives before trading.
These moves indicate that the largest sportsbook companies do not view prediction markets only as an external threat. They also see them as a distribution channel, a customer-acquisition product and a way to expand beyond states where online sports wagering is legal.
Regulation Remains the Central Divide
The largest unresolved issue is jurisdiction.
Traditional online sportsbooks operate under state gaming laws. They must obtain licenses in each jurisdiction, follow state tax rules, use approved geolocation systems and comply with local requirements involving age verification, advertising, responsible gambling and market integrity.
CFTC-regulated prediction markets operate under federal commodities law. The CFTC has argued that it has exclusive jurisdiction over qualifying event-contract markets, while several state regulators and lawmakers contend that sports contracts function like wagering and should remain subject to state gaming laws.
On March 12, 2026, the CFTC’s Division of Market Oversight issued an advisory reminding designated contract markets of their obligations under the Commodity Exchange Act and commission regulations. The advisory specifically noted that certain regulatory requirements may have particular relevance to sports-related event contracts.
The commission also requested public comment through an advance notice of proposed rulemaking published in March. The notice asked which event contracts might be considered contrary to the public interest and how existing statutory principles should apply to the expanding sector.
State-federal conflict continued after the World Cup. On July 29, a federal judge temporarily blocked a Minnesota law that sought to prohibit prediction markets. U.S. District Judge Katherine Menendez found that the CFTC, Kalshi and Polymarket had raised substantial arguments concerning federal jurisdiction. Minnesota Attorney General Keith Ellison and state officials maintained that sports contracts amount to gambling subject to state authority.
That dispute is unlikely to disappear quickly. Prediction markets benefit from potential national reach, while traditional sportsbooks have invested billions of dollars in state licensing systems. The final regulatory treatment will influence taxes, market access, age limits, product availability and consumer safeguards.
Market Liquidity Can Matter More Than the Interface
The World Cup showed that prediction-market scale depends heavily on liquidity.
A contract price is meaningful only when customers can trade at or near the displayed level. A thin market may show an attractive headline price but provide limited capacity at that price. Larger orders can move the market or execute across several price levels.
Traditional sportsbooks address the same problem differently. They set limits, adjust prices or restrict certain markets according to risk. A customer may see a quoted number but discover that the operator accepts only a smaller stake than expected.
Prediction exchanges may offer greater flexibility because traders can enter and exit positions. However, that benefit is strongest in liquid markets involving high-profile teams and events. Less popular soccer matches may have wide bid-ask spreads or insufficient depth.
A recent academic paper on prediction-market liquidity emphasized that market makers must manage both inventory risk and the risk that unsettled positions resolve against them. The analysis found that optimal pricing depends on market beliefs, time remaining and the amount of inventory held.
This is one reason the World Cup was such a powerful growth event. Matches involving Argentina, Spain, the United States, Brazil, England and other heavily followed teams attracted enough participation to create deeper markets than ordinary soccer fixtures.
The post-tournament challenge is maintaining that depth when the betting calendar returns to club competitions and less widely followed international matches.
Prediction Markets Introduce Different Consumer Risks
Both sportsbooks and prediction markets involve financial risk. Their terminology should not obscure that reality.
A losing sportsbook wager results in the stake being lost. A prediction contract bought at 65 cents can also become worthless if the selected outcome does not occur. The ability to sell early may reduce or lock in a loss, but only when sufficient liquidity exists.
Prediction-market language can make the activity appear closer to investing than gambling. Terms such as trading, contracts, positions and portfolios may encourage users to view the products differently from sportsbook wagers even when the underlying event is a soccer match.
The CFTC advises customers to understand fees, contract rules, settlement procedures and the risks of speculation. It also warns users to trade only with money they can afford to risk and to verify that platforms are properly registered.
Traditional sportsbooks have their own risks, including rapid live betting, promotional pressure and highly complex parlays. State regulators generally require responsible-gambling resources, but the specific protections vary by jurisdiction.
The appropriate comparison is therefore not which model removes risk. Neither does. The more useful questions concern transparency, pricing, liquidity, settlement clarity and customer protections.
Sportsbooks Still Hold Important Advantages
Prediction markets gained substantial share during the World Cup, but conventional sportsbooks remain deeply established.
Sportsbooks offer mature soccer interfaces, extensive live betting, same-game parlays, customer-support systems and integrated casino or fantasy products. They also have years of experience pricing sport-specific markets and managing official data feeds.
Their state licenses can provide a clear legal framework for customers. Rules involving voided wagers, abandoned matches, disputed settlements and responsible-gambling tools are generally documented and supervised by identifiable gaming authorities.
Sportsbooks also benefit from familiar odds formats. Many American users understand moneylines, spreads and totals more readily than exchange order books and bid-ask spreads.
Prediction markets have different advantages. Their prices can be easier to interpret as percentages, they may offer national reach and they allow customers to sell positions before settlement. Their peer-to-peer structure can also create competitive pricing in liquid markets.
The World Cup did not establish a universal winner. It demonstrated that each format appeals to different behaviors.
The Post-World Cup Market Is Moving Toward Convergence
The most likely outcome is not the disappearance of one model. It is continued convergence.
DraftKings and FanDuel now operate traditional sportsbooks while also offering event-contract products. Exchange platforms are expanding sports menus until they resemble conventional betting boards. Sportsbooks are adopting trading-style interfaces, cash-out options and probability-based displays.
The distinction will remain important for regulators and legal experts, but it may become less visible to consumers.
For soccer bettors, the post-World Cup environment provides more places to compare prices. A regulation-time match result may be available as a sportsbook 1X2 wager, a binary exchange contract or several separate outcome contracts.
That creates additional choice, but it also creates more complexity. Customers must compare implied probability, operator margin, transaction fees, liquidity, settlement rules and whether the market includes extra time or penalties.
The 2026 World Cup proved that prediction markets can compete for mainstream U.S. sports activity at scale. Kalshi’s reported $27 billion in tournament trading volume and the sector’s estimated 27% share of legal sports activity represented a significant change from the start of the year.
Traditional sportsbooks remain larger, familiar and heavily integrated into state-regulated gambling systems. Prediction markets offer a different structure with wider potential access and active trading functionality.
After the World Cup, the competition is no longer about whether prediction markets will enter sports. They already have. The next stage will determine how regulators classify them, how sportsbook companies integrate them and whether customers continue using them once the extraordinary attention surrounding the tournament fades.
