LaLiga just became the first European soccer league to enter prediction markets — the same week a bipartisan Senate bill was introduced to shut them down. On April 2, Polymarket announced a multi-year exclusive partnership with LaLiga for the United States and Canada, adding Europe’s most-watched domestic league to a sports portfolio that already includes MLB, NHL, MLS, and UFC. But the celebration may be premature: days later, Senators Adam Schiff and John Curtis introduced the STOP Act, which would ban sports prediction market contracts entirely.
KEY FACTS AT A GLANCE
- Historic first: LaLiga is the first European soccer league to partner with any prediction market platform
- Deal scope: Multi-year exclusive partnership covering the United States and Canada only
- Existing market: $106.9 million already traded on La Liga outcomes across 242 Polymarket contracts
- Integrity layer: Palantir-powered Vergence AI platform monitors all sports markets for manipulation
- Regulatory threat: Bipartisan STOP Act introduced the same week could ban all sports prediction contracts
What the Deal Includes
Under the agreement, Polymarket becomes the Official and Exclusive Prediction Market Partner of LaLiga in the United States and Canada. The multi-year deal — whose financial terms remain undisclosed — gives Polymarket exclusive branding rights and access to LaLiga and individual club intellectual property, including logos and marks for event markets. Official event contracts for teams like Real Madrid and FC Barcelona will live exclusively on Polymarket.
In return, LaLiga gets digital and social content integration, premium broadcast visibility across selected channels, VIP match hospitality for fan activations, and virtual meet-and-greets with LaLiga legends. The partnership also gives LaLiga access to Polymarket’s Vergence AI integrity platform.
“Soccer’s growth, especially in North America, is spearheaded by young, diverse and multicultural audiences who consume the game across multiple screens, so it’s our goal to continue to engage these demographics in new and unique ways.”
— Boris Gartner, Relevent CEO (operates LaLiga North America)
“Our goal is to give fans a more expressive way to follow the game, where opinions on players, matches, and season outcomes can be reflected in real time.”
— Shayne Coplan, Polymarket Founder & CEO
$106 Million Before the Handshake
The partnership didn’t create a market — it formalized one that already existed. Before the announcement, Polymarket users had already wagered $106.9 million on La Liga outcomes across 242 active markets. The concentration is striking: $105.6 million of that volume sits on a single market — “La Liga Winner” — which has been live since July 28, 2025.
That existing demand is what made the deal inevitable. As Polymarket’s President of Sports Business Development Ari Borod put it: “There’s a lot of investment in, and focus on, the game of soccer in the U.S. right now. LaLiga is one of the most iconic sports leagues on the planet.” Borod, formerly of Fanatics, has been leading Polymarket’s aggressive push into sports partnerships since the platform received CFTC regulatory clearance in September 2025.
Polymarket’s Seven-Month Sports Blitz
LaLiga is the fifth major sports league to partner with Polymarket in just seven months — a pace that would have seemed impossible before the platform even had US regulatory clearance. The acceleration reflects a broader power shift between traditional sportsbooks and prediction markets that is reshaping the sports betting landscape.
The MLB deal, reportedly valued at $150–300 million over three years, set the benchmark. While LaLiga’s financial terms remain undisclosed, the deal structure mirrors MLB’s: exclusive branding, IP access, and integrity commitments. Polymarket’s daily platform fees surged from roughly $363,000 to over $1 million within days of recent sports expansion announcements — as we covered in our breakdown of the MLB-Polymarket deal.
The Integrity Architecture
Both sides emphasized that integrity was non-negotiable. LaLiga’s Managing Director for North America, Nicolas Garcia Hemme, revealed that the league pursued discussions with multiple prediction platforms before selecting Polymarket — and that the integrity framework was a deciding factor.
“There’s nothing specific on, no yellow cards, no penalty kicks. It’s more, if we deem that something is not according to our guidelines, we have the capacity to limit or block this kind of option to do prediction markets.”
— Nicolas Garcia Hemme, LaLiga Managing Director for North America
The exclusion of micro-events — individual yellow cards, penalty kicks, and other easily manipulated in-game actions — is a direct response to integrity concerns that have plagued sports betting more broadly. MLS already suspended two players for betting violations, and the NFL sent cautionary letters to prediction platforms about categories like field goals and announcer remarks.
Polymarket’s integrity backbone is the Vergence AI platform, a joint venture with Palantir Technologies and TWG AI launched in March 2026. The system provides end-to-end trade monitoring, near real-time anomaly detection, restricted participant screening, and automated trade alerts. As Borod noted: “Integrity was at the foundation of this deal. It wasn’t something that we figured out after the fact.”
Who’s In and Who’s Out
Polymarket’s league-collecting spree has been remarkably one-sided. Five major sports organizations have signed on in seven months. But two of the biggest — the NBA and NFL — remain conspicuously absent, reflecting what some have called the ongoing identity crisis facing prediction markets: are they financial instruments or sports bets?
The NFL’s resistance is especially notable. The league sent cautionary letters warning about easily manipulated trading categories and banned prediction market platforms from running Super Bowl ads. The NBA hasn’t signed a deal either, though competitor Kalshi has secured investor backing from NBA-affiliated entities. Meanwhile, a 39-state coalition has filed amicus briefs against prediction market platforms in federal court.
The Regulatory Storm
The timing of the LaLiga announcement could not be more ironic. Days after Polymarket secured its fifth major league partner, Senators Adam Schiff and John Curtis introduced the STOP Act — a bipartisan bill that would prohibit CFTC-regulated platforms from offering sports event contracts and ban casino-style products on prediction exchanges.
“Sports prediction contracts are sports bets — just with a different name.”
— Senator Adam Schiff, on introducing the STOP Act
The regulatory pressure extends well beyond Capitol Hill. Eleven states have filed lawsuits against prediction market platforms, arguing they evade state and tribal consumer protections, generate no public revenue, and undermine established gaming oversight. A Morning Consult poll found that 81% of Americans view sports futures on prediction platforms as gambling, and 77% are concerned about teenagers accessing what are effectively sports bets through platforms with lower age requirements than traditional sportsbooks.
Internationally, the picture is no easier. The Netherlands has banned Polymarket as illegal gambling, and European regulators are beginning to weigh in on how prediction markets should be classified. The fact that LaLiga’s deal is limited to the US and Canada — not Europe, where the league is headquartered — speaks volumes about the regulatory uncertainty on the continent.
REGULATORY WATCH
The STOP Act, 11 state lawsuits, and ongoing CFTC rulemaking could reshape or eliminate the legal framework that makes these partnerships possible. The core dispute — whether prediction markets are financial instruments or sports bets — remains unresolved in federal court.
KEY TAKEAWAYS
- European first — LaLiga is the first European soccer league to partner with any prediction market platform, joining MLB, NHL, MLS, and UFC
- Market existed before the deal — $106.9 million was already traded on La Liga outcomes across 242 Polymarket contracts before the partnership was announced
- Integrity as the deciding factor — LaLiga evaluated multiple platforms and chose Polymarket partly because of its Palantir-powered Vergence AI integrity system
- US and Canada only — The deal excludes Europe entirely, reflecting regulatory uncertainty around prediction markets in the EU
- Regulatory collision course — The STOP Act, introduced the same week, could ban all sports prediction market contracts under CFTC jurisdiction
- NBA and NFL remain holdouts — The two highest-value US sports leagues have declined prediction market partnerships, citing manipulation risks

The broader prediction market industry grew fourfold in 2025, hitting $63.5 billion in total trading volume — up from roughly $15.8 billion in 2024. Monthly active users surged from around 4,000 to over 600,000 in the same period. Industry projections suggest prediction market volumes could exceed $325 billion in 2026 based on year-to-date run rates, with some analysts projecting a $1.1 trillion market by 2030.
Sports contracts are the engine driving this growth. Sports accounted for 89% of Kalshi's 2025 fee revenue at $235 million, with the share exceeding 90% in the final four months of the year. Kalshi's Super Bowl single-day trading volume hit $871 million — double the combined volume of DraftKings and FanDuel on the same day. The company also became the infrastructure powering Robinhood's prediction markets hub, with 11 billion contracts traded by more than one million Robinhood customers as of February 2026.
The Sportsbook Industry Trembles
For traditional sportsbook operators, the Third Circuit ruling is an existential threat. The power shift between sportsbooks and prediction markets is already visible in the stock market: DraftKings shares have fallen roughly 35% from a year ago, while Flutter Entertainment — FanDuel's parent company — is down 56% since August. Meanwhile, Kalshi has overtaken DraftKings in valuation.
The competitive advantage is structural. Kalshi operates under a single federal license from the CFTC, avoiding the state-by-state licensing, compliance costs, and tax obligations that traditional sportsbooks must navigate across approximately 40 states. This creates a fundamental asymmetry that licensed sportsbook operators argue is unfair.
THE COMPETITIVE LANDSCAPE
KALSHI MODEL
- Single federal CFTC license
- Binary yes/no event contracts
- No state licensing required
- No state gambling taxes
- 18+ minimum age
- $22B valuation (Mar 2026)
TRADITIONAL SPORTSBOOK MODEL
- State-by-state licensing in 40+ states
- Fractional/decimal odds betting
- Individual state compliance required
- State gambling taxes apply
- 21+ minimum age in most states
- DraftKings down 35% YoY
Congress Pushes Back
The legislative branch is not sitting idle while courts and regulators reshape the gambling landscape. On March 23, 2026, Senators John Curtis (R-Utah) and Adam Schiff (D-California) introduced the "Prediction Markets Are Gambling Act" — the Senate's first bipartisan bill aimed directly at prediction markets. The legislation would amend federal law to prevent CFTC-registered entities from listing any prediction contract that resembles a sports bet or casino-style game.
The bill's sponsors argue that prediction market contracts "evade state and tribal consumer protections, generate no public revenue, and undermine sovereign tribal regulatory regimes." The data backs up the scale of the concern: a March Madness winner contract on Kalshi already had more than $100 million in trading volume, while Super Bowl trading volume on prediction markets surpassed $1 billion in 2026.
Whether the legislation can pass a Congress that has generally been friendly to deregulation remains to be seen, but it signals that the prediction market question has reached the highest levels of American policymaking — and that not everyone in Washington is convinced the CFTC should have sole authority over what many see as gambling by another name.
The Consumer Protection Gap
Perhaps the most uncomfortable question raised by the Third Circuit ruling is what happens to consumer protections when prediction markets operate outside state gambling frameworks. Traditional sportsbooks are subject to extensive state oversight: age verification (21+ in most states), responsible gambling programs, self-exclusion lists, tax contributions, and marketing restrictions.
CONSUMER PROTECTION CONCERNS
- Age gap: Kalshi allows users aged 18+, while most state sportsbooks require 21+
- College targeting: Kalshi has paid college student influencers to promote the platform on campuses, and reportedly attempted to recruit a 15-year-old influencer
- No state taxes: Prediction markets generate zero gambling tax revenue for states
- No state oversight: No state-level responsible gambling requirements, self-exclusion programs, or marketing restrictions apply
- No tribal protections: State-tribal gaming compacts are bypassed entirely
New Jersey Attorney General Jennifer Davenport made this point explicitly in her reaction to the ruling, saying it will "allow certain companies to offer sports gambling in our states without following the careful gaming rules that everyone else follows." Nevada's attorney general has similarly argued that Kalshi is operating an illegal gambling business without the proper state license and — critically — allowing users under 21 to place bets.
"We profoundly disagree with today's decision... [it will] allow certain companies to offer sports gambling in our states without following the careful gaming rules that everyone else follows."
— Jennifer Davenport, New Jersey Attorney General
The Political Dimension
The Trump administration's CFTC has been one of the prediction market industry's most vocal defenders, and the political dimensions of this alliance are impossible to ignore. Donald Trump Jr. serves as a strategic advisor to Kalshi and is separately an investor and advisory board member at Polymarket, having invested "double-digit millions" through his Palm Beach-based 1789 Capital.
Critics have noted the appearance of a conflict of interest: any favorable CFTC decision on prediction markets could financially benefit the president's family. Trump Jr.'s spokesperson has stated that his role with both companies is limited to marketing advice and that he has not interacted with the federal government on behalf of either platform.
The political picture grows more complex with the 39-state coalition that filed amicus briefs opposing Kalshi in the Ninth Circuit case, and the hiring of Stephanie Cutter — a former Obama strategist — by Kalshi, signaling the company is building bipartisan lobbying firepower. Both parties have members on each side of this fight, making prediction market regulation one of the rare issues that doesn't fall neatly along partisan lines.
What Happens Next
The Third Circuit ruling is a landmark, but it is far from the final word. The legal and political landscape will shift rapidly in the coming weeks and months.
UPCOMING DATES TO WATCH
- April 16, 2026: Ninth Circuit hears consolidated Nevada case — a ruling here could deepen or resolve the circuit split
- May 7, 2026: Fourth Circuit hears Maryland appeal with Neal Katyal arguing for Kalshi — a loss here virtually guarantees Supreme Court review
- TBD: New Jersey AG evaluating options — could seek en banc review or Supreme Court petition
- TBD: Senate action on the "Prediction Markets Are Gambling Act"
Kalshi CEO Tarek Mansour celebrated the ruling, stating "This is a big win for the industry and millions of users. People use prediction markets because they are fairer, more transparent, and reward being right. Free markets work. We should keep them that way."
But the prediction market industry's legal fate is far from settled. The Third Circuit has established a powerful precedent, but conflicting rulings in other circuits, aggressive state enforcement actions, bipartisan congressional legislation, and mounting consumer protection concerns suggest the ultimate resolution will come from the Supreme Court — where the justices will have to answer the question that Judge Roth posed in her dissent: can you really turn a sports bet into a financial instrument just by calling it one?
KEY TAKEAWAYS
- First-ever appeals court ruling — The Third Circuit became the first federal appeals court to rule on prediction market jurisdiction, finding that the CFTC has exclusive authority over Kalshi's event contracts
- Federal preemption affirmed — States cannot enforce gambling laws against CFTC-licensed prediction market operators in NJ, PA, and DE
- Circuit split deepening — Courts in NJ and TN back Kalshi; courts in MA, OH, NV, and MD rule against it — a classic setup for Supreme Court review
- CFTC goes on offense — The federal regulator sued Arizona, Connecticut, and Illinois to block state enforcement, signaling aggressive defense of its jurisdiction
- Industry exploding — Prediction market trading volume grew 4x to $63.5B in 2025; Kalshi's valuation hit $22B; projections suggest $325B+ in 2026
- Sportsbooks under pressure — DraftKings and Flutter shares have dropped significantly as Kalshi captures market share without state licensing or taxes
- Consumer protection gap — Prediction markets allow 18+ users, lack state oversight, and generate no gambling tax revenue — a growing concern for regulators
- Watch April 16 and May 7 — The Ninth and Fourth Circuit hearings will determine whether this issue reaches the Supreme Court within the year
