Headline: Prediction markets boom runs into a wave of legal and political pushback — 2027 could be decisive
The once-rocketship ascent of crypto-enabled prediction markets has collided with a growing backlash from state and federal officials — and the fallout could reshape the industry by 2027.
What happened
- Prediction markets like Polymarket and Kalshi have seen explosive growth, with activity leaping from about $1.2 billion in monthly volume at the start of 2025 to more than $20 billion a year later, according to TRM Labs. Political-event contracts lead the rise, followed by sports.
- These platforms let users wager on a wide range of real-world outcomes: which words President Donald Trump might use in a speech, an album release date, a billionaire’s net worth by month-end, or which baseball team wins the AL pennant. Mainstream firms (Coinbase, Crypto.com), institutional partners and gambling operators have also entered the space.
Why officials are alarmed
- Regulators and many lawmakers say some markets blur the line between federally regulated derivatives and state-controlled gambling. For example, a $100 BetMGM wager on a March Madness game yields payouts that look nearly identical to equivalent contracts on Kalshi — a similarity states argue should trigger gambling oversight.
- Other concerns are more acute: certain government-action markets (war, assassination) and apparent “phantom” bettors who profited by predicting military operations have spurred accusations of insider trading and manipulation.
High-profile incidents and legal escalation
- TRM Labs flagged one market — “Will the US strike Iran by Feb 28, 2026?” — as Polymarket’s largest-ever, attracting $73 million in interest. TRM identified four wallets that placed about $40,000 in bets and later collected roughly $872,000. The wallets were newly active, funded similarly over a narrow period, and went dormant after winning. TRM stopped short of calling it proof of insider trading, but the pattern alarmed investigators.
- States have responded aggressively: Nevada’s court halted Kalshi’s operations, Washington has filed complaints, and Arizona’s attorney general charged Kalshi with 20 criminal counts alleging an unlicensed gambling business that offered illegal election wagering.
- “Every day brings a new lawsuit,” said Liz Davis, former CFTC chief trial attorney, now a partner at Davis Wright Tremaine. Legal experts expect jurisdictional fights to wind up before the Supreme Court and call the current landscape a “minefield.”
Federal regulators push back — and move to regulate
- The Commodity Futures Trading Commission (CFTC), led by Chairman Mike Selig, argues these exchanges fall under federal derivatives jurisdiction. Selig has filed briefs asserting CFTC authority, emphasized that Kalshi and Polymarket are registered designated contract markets, and said the agency is working on rulemaking and enforcement.
- The CFTC secured an unprecedented memorandum of understanding with Major League Baseball for information sharing and has pointed to recent enforcement moves: Kalshi suspended and fined a producer linked to a Mr. Beast event and a politician who bet on his own gubernatorial run; Polymarket updated market-integrity rules to bar trading on tips, stolen information, or by people who can influence outcomes.
- Federal prosecutors have reportedly been in touch with platforms about possible insider-trading risks.
The political chessboard
- More than half a dozen bills targeting prediction markets have been introduced in Congress, many sponsored by Democrats but supported across party lines. Betting market odds show Democrats with a strong chance to retake the House and a near-even shot at the Senate, which could give those bills momentum after the 2026 elections.
- But any legislation would face President Trump, who has personal and political ties to the sector: his son Don Jr. advises Kalshi and Polymarket; a venture fund involving Don Jr. invested in Polymarket; the Trumps’ stake in World Liberty Financial links them to Myriad, which uses WLF’s USD1 stablecoin. President Trump has publicly praised prediction markets’ forecasting record and has made crypto-friendly policies a priority — a possible White House counterweight to congressional restrictions.
State-first enforcement
- While Congress and the CFTC jockey for control, states are not waiting. Nevada, Washington and Arizona have moved in court or with criminal charges. Advocacy groups like the newly formed Gambling Is Not Investing Coalition (led by former White House chief of staff Mick Mulvaney) are pressing the argument that “if it looks like gambling and functions like gambling, it should follow gambling rules,” and that states and tribal governments are the appropriate regulators.
- Meanwhile, some public officials are self-policing: California Governor Gavin Newsom has restricted state officials from making prediction-market trades where they might have inside information, and Rep. Seth Moulton banned his staff from participating in markets that intersect with their work.
Industry posture and outlook
- Prediction-market firms are fighting back publicly. Kalshi runs ads in Washington, D.C., proclaiming “RULE #1, KALSHI BANS INSIDER TRADING” and emphasizes federal regulation; Polymarket tightened integrity rules. The CFTC says platforms are capable of policing fraud and manipulation, while the agency proceeds with rulemaking — a process CFTC observers say could conclude sooner than usual because Selig is currently the sole commissioner.
- Legal analysts say the battle will likely take years and reach the Supreme Court. Jake Preiserowicz, a former CFTC special counsel, called it “up in the air” which congressional measures will advance but warned the jurisdictional tussle will be litigated and regulated aggressively.
What to watch next
- Court rulings in state cases (Nevada, Washington, Arizona) and any criminal prosecutions could set precedents that reshape the market.
- The CFTC’s rulemaking and any final rules — possibly fast-tracked under Chairman Selig — will determine whether prediction markets remain a federally regulated derivative product or are parceled out to state gambling regimes.
- Further forensic work on suspicious markets (like the Iran strike example) and potential insider-linked arrests would add political fuel to congressional proposals.
Bottom line
Prediction markets are no longer a niche crypto experiment; they’ve become a high-stakes policy fight with legal, ethical and political implications. Between state lawsuits, congressional bills, CFTC rulemaking and the potential for insider-trading probes, the ecosystem’s future — and how it intersects with gambling and securities law — could be decided in the next 18–24 months.
