The 2026 FIFA World Cup has become a record-breaking event for Kalshi, with billions of dollars flowing through its prediction markets and intensifying debate over whether the platform should legally be treated as a sportsbook.
While Kalshi maintains it operates a federally regulated financial exchange, critics argue that, from a customer’s perspective, its products closely resemble traditional sports betting.
Record World Cup Trading Volume
According to market analytics, Kalshi has processed approximately $40 billion in World Cup-related trades during the tournament.
That figure far exceeds estimates for traditional online sportsbooks such as DraftKings and FanDuel, which analysts project will handle roughly $4 billion in wagers across all tournament matches.
The surge has made sports-related contracts the dominant activity on Kalshi, where sporting events reportedly account for 80% to 90% of total trading volume.
Why Kalshi Says It Isn’t Gambling
Kalshi argues that its platform differs fundamentally from a sportsbook.
Unlike traditional sports betting operators:
- Users trade contracts against one another rather than betting against the company.
- Kalshi earns transaction fees instead of profiting directly from customer losses.
- Traders can buy and sell positions before an event concludes, similar to financial markets.
- The platform also offers contracts tied to politics, economics, weather, entertainment, and other real-world events.
Company representatives describe Kalshi as a federally regulated derivatives exchange, not a gambling operator.
Sports Betting Industry Pushes Back
Traditional sportsbook operators strongly disagree.
Industry representatives argue that Kalshi offers wagers nearly identical to conventional sports betting, including:
- Match winners
- Player performances
- Parlays (marketed by Kalshi as “combos”)
- Total goals or points
- First-half outcomes
- Live event propositions
Critics contend that consumers experience little practical difference between betting on Kalshi and placing wagers through licensed sportsbooks.
Legal Advantages Under Scrutiny
One of the biggest disputes centers on regulation.
Because Kalshi is regulated federally rather than through individual state gaming commissions, the platform currently operates in states where traditional online sports betting remains illegal.
The platform also allows users 18 years and older to participate, while many states require bettors to be 21 for licensed sportsbooks.
This regulatory framework has triggered lawsuits and enforcement actions from multiple states that argue Kalshi is effectively conducting unauthorized sports gambling.
Tax Revenue at the Center of the Fight
Licensed sportsbooks typically pay significant state gaming taxes that help fund public programs.
Depending on the state, those taxes support:
- Public education
- Infrastructure projects
- Water conservation
- Responsible gambling programs
Industry groups argue that prediction markets compete directly with sportsbooks while avoiding billions of dollars in annual state gaming taxes.
Kalshi responds that it complies with all applicable federal tax laws and supports reasonable state taxation where appropriate.
Courts Continue to Weigh the Issue
The legal status of prediction markets remains unsettled.
Several states have attempted to restrict or prohibit sports-related prediction markets, while federal regulators have defended Kalshi’s authority to operate under commodities law.
Legal experts widely expect the dispute to eventually reach the U.S. Supreme Court, where a final ruling could determine whether prediction markets remain distinct financial products or become subject to state gambling regulations.
A Fast-Growing Industry
Regardless of the legal outcome, prediction markets have expanded rapidly over the past year.
Sports remain their largest category, but markets covering elections, politics, economic data, and entertainment continue to grow alongside them.
As betting volumes increase and regulatory battles intensify, Kalshi has become one of the most closely watched companies at the intersection of finance, technology, and sports wagering.
