On 24 September 2026 the New York Attorney General filed a verified petition against QCX LLC, which trades as Polymarket US, pleading eight predicates of illegality under Executive Law § 63(12) drawn from the state Constitution, the Penal Law, the Racing Law and the federal Wire Act. Prokopiev reads the counts one by one and finds the Penal Law predicates strongest, because a $3.01 stake on the Mets fits the statutory definition of gambling on its face — the contested element is 'unlawful', which New York defines as 'not specifically authorized by law', leaving Polymarket to argue that a CFTC designation and an unreviewed self-certification supply that authorization. Preemption therefore decides the case, and the circuits are split: the Third Circuit treated self-certified sports contracts as swaps within the CFTC's exclusive jurisdiction and 'presumptively approved', while the Ninth Circuit held they are not swaps and that Rule 40.11 still bars gaming contracts, and the district court closest to this forum rejected preemption outright. On the authority available in September 2026 a New York court is more likely to reject preemption than accept it, and the author also flags what the petition overreaches on: a Racing Law penalty capped at $5 million that the prayer ignores, a treble-gain fine that has no civil vehicle in a § 63(12) proceeding, and restitution language broad enough to pay winning traders too.

Industry-friendly regulators at the CFTC are not merely going easy on prediction markets, they are trying to make it structurally hard for a future, less friendly commission to reverse course. Shaw walks through a proposed rule that gives the CFTC just 10 days to open a public-interest review of a newly listed event contract, then treats the agency's failure to act as affirmative final approval of that contract after 100 days. Because the deemed approval would attach to hundreds of thousands of contracts the commission never touched, the proposal manufactures reliance interests and a 'justification tax' that any future delisting must distinguish, arguably weaponizing the Supreme Court's change-in-position doctrine against regulators. Shaw's focus is procedural rather than the substance of the 'gaming' definitions: the CEA sets no deadline for initiating review, Congress declined to add one where it added a 10-day clock for exchange rules elsewhere in the same section, and a shrinking, DOGE-purged agency cannot plausibly screen 162,000 daily contract listings in 10 days.

A Bocconi law professor reads the transatlantic puzzle at the centre of prediction market regulation: US appeals courts are split on whether event contracts are federally regulated derivatives or state-regulated wagers, with the Third Circuit accepting CFTC jurisdiction in April and the Ninth Circuit rejecting it on August 28. Annunziata shows that EU law already lands where the Ninth Circuit landed, treating a contract on a discrete fact like who wins a match as a wager rather than a financial instrument, which is why Belgium, France, Italy, Poland and Romania have blocked access to the platforms. The classification question is a choice between protecting retail savers and letting them speculate, and it is now before the Supreme Court and the European Commission.

Connecticut is the latest state to sue Kalshi, and the pattern is becoming a rout: Nevada, Washington, Michigan, and New York have already cordoned off sports prediction contracts, with New York seeking $36 billion and a court-ordered shutdown. Courts keep rejecting Kalshi's federal preemption defence with the same reasoning — when the product looks like sports betting, states can treat it like sports betting, derivatives wrapper or not. Paige notes the commercial irony: the CFTC keeps intervening on Kalshi's behalf while each state loss shrinks the addressable market its Cantor Fitzgerald institutional channel depends on.

States and Kalshi are warring over whether sports-event contracts are gambling or federally regulated derivatives — and the fight looks headed to the Supreme Court. The Third Circuit sided with Kalshi on CFTC preemption, but the Ninth Circuit, hearing Nevada's challenge, appears poised to create the circuit split that forces the justices to step in. Dieterle walks through the statutory hooks (the 1974 CEA amendments, CFMA 2000, Dodd-Frank) and reads the Court's recent anti-preemption voting patterns to handicap how it would rule — with the major questions doctrine looming as Kalshi's biggest risk.

A former CME board member who helped negotiate the CFMA 2000 argues for bifurcating prediction market regulation: sports and entertainment betting under state gaming laws, while economically valuable markets (politics, weather, economic releases) stay under CFTC oversight. Makes the case that the all-or-nothing regulatory debate misses a win-win compromise.

The first rigorous estimate of U.S. user activity on offshore prediction market platforms finds that ~30% of Polymarket's $55.6B trailing twelve-month volume comes from U.S.-based users. Across all offshore platforms, U.S. activity totals $11-34B, representing 12.5-31.5% of all U.S. prediction market volume. Prepared for the Coalition for Prediction Markets, the report estimates offshore U.S. volume could reach $133B annually by 2030.

Breaks down the legal fight over whether sports event contracts are "swaps" under the Commodity Exchange Act, which would give the CFTC exclusive jurisdiction and preempt state gambling laws. Courts are split across 19 pending federal lawsuits, with the Third Circuit ruling in Kalshi's favor. The case hinges on how broadly to read two phrases in Dodd-Frank's swap definition and will likely reach the Supreme Court within two years.

Congressional Research Service legal sidebar analyzing whether and how insider trading law applies to prediction markets. Walks through SEC Rule 10b-5, CFTC Rule 180.1, the STOCK Act, and Title 18 criminal statutes, then examines the CFTC's February 2026 advisory on two Kalshi enforcement actions. Identifies the core gap: existing law requires breach of a duty, but many prediction market insiders (e.g., a political candidate betting on his own race) may not owe one. Surveys four pending bills in the 119th Congress that would close this gap in different ways.

Written by a former CFTC General Counsel, argues that courts in sports event contract litigation are overlooking the strongest basis for CFTC jurisdiction: the Commodity Exchange Act's 'commonly known to the trade' catchall, which classifies any transaction the derivatives industry calls a swap as one. Since every exchange, broker, and clearinghouse involved treats sports event contracts as swaps, the test resolves the federal preemption question cleanly while preserving state authority over off-exchange sports betting.

History of U.S. prediction market regulation culminating in the February 2026 jurisdictional standoff between CFTC Chairman Mike Selig and Utah Governor Cox. Park traces the arc from the Iowa Electronic Markets' 1988 no-action letter, through Intrade's 2012 collapse and the binary options fraud era, to Kalshi's court win establishing that 'gaming' does not cover financial contracts on uncertain outcomes. Argues federal preemption under the Commodity Exchange Act will hold against state attorneys general, and that Bitwise's PredictionShares ETF launch marks the point where political event contracts become a mainstream financial product.

Grace Deng from SevenX Ventures compares prediction markets against sports betting incumbents like DraftKings across product, business model, and legal dimensions. Parlay complexity gives traditional sportsbooks a structural advantage that orderbook-based platforms cannot easily replicate. The article argues that convergence rather than replacement will define the next phase—hybrid models where PMs and sportsbooks interoperate.
