"It is time for clear rules and a clear understanding that the CFTC supports lawful innovation in these markets." — Michael Selig, Chairman, U.S. Commodity Futures Trading Commission
The U.S. Commodity Futures Trading Commission on June 10, 2026 published a 267-page proposed rulemaking that would formalize federal oversight of prediction markets — an asset class that grew from under $5 billion in monthly volume in September 2025 to $24 billion in April 2026. The proposal permits most sports outcome contracts while banning markets on player injuries, officiating decisions, and single-play micro-bets. A 90-day public comment period is now open.
The rulemaking arrives amid an escalating federal-state jurisdictional war. Forty-one state attorneys general have filed comments asserting prediction market contracts are indistinguishable from sports betting. The CFTC has sued four states — New York, Arizona, Connecticut, and Illinois — to assert exclusive federal regulatory authority. Arizona filed the first criminal charges against Kalshi in March 2026 for allegedly operating an unlicensed gambling business.
Combined, Polymarket and Kalshi now represent a market generating an estimated $1.5 billion in annualized platform revenue, with 5.1 million active monthly users on Kalshi alone and 840,000 unique wallets on Polymarket. Intercontinental Exchange (NYSE parent) has invested approximately $2 billion in Polymarket at an implied $9 billion valuation. The sector has attracted attention from Pew Research Center, which published its first analysis of prediction market volume in May 2026.
According to TRM Labs, aggregate monthly trading volume across prediction markets climbed from $1.2 billion in early 2025 to over $21 billion by January 2026. Pew Research Center, citing data from The Block, reported combined monthly volume on Kalshi and Polymarket rose from $810.2 million in July 2024 to $23.8 billion in April 2026 — an increase of 2,838% in under two years.
Polymarket recorded $10.57 billion in monthly volume in March 2026, with Q1 2026 total volume reaching $26.2 billion, up more than 90% quarter-over-quarter. The platform set a single-day record of $425 million on February 28, 2026. Monthly unique wallets nearly tripled in six months, reaching 840,000 by February 2026.
Kalshi's monthly volume surpassed $10 billion in February 2026, approximately 12 times higher than levels six months prior. Total 2026 volume through May exceeds $28 billion. Active monthly users rose from 600,000 to 5.1 million since the start of 2025.
Market composition differs materially between the two platforms. According to Pew Research, sports account for 80% of Kalshi's total volume since July 2024. Sports represent 39% of Polymarket's volume during the same period. Geopolitics, macroeconomics, and politics drive the majority of non-sports activity.
Mid-frequency traders (11–1,000 fills) and high-frequency market makers together account for roughly 80% of volume, according to TRM Labs — indicating institutional-grade market structure rather than retail speculation.
The 267-page proposal, published June 10, 2026, seeks to amend regulations governing "event contracts" under the Commodity Exchange Act (CEA). The core framework establishes a case-by-case review process rather than blanket permissions or prohibitions.
Permitted contracts:
Banned or restricted contracts:
The distinction hinges on a "public interest" test mandated by the CEA. Contracts vulnerable to manipulation — where a small number of participants could influence outcomes — face the highest scrutiny. The proposal does not constitute a final rule; a 90-day comment period precedes any adoption.
Chair Selig stated in May 2026 that prediction markets and sports betting are "two separate things," arguing most participants use them for "financial" rather than "entertainment" purposes. This framing underpins the CFTC's claim to exclusive jurisdiction.
The prediction markets sector faces a constitutional confrontation over regulatory preemption.
State actions (as of June 2026):
Federal response:
The legal question: Does registration as a CFTC-regulated Designated Contract Market (DCM) preempt state gambling laws? The CEA's preemption provisions have never been tested against state gambling statutes at this scale. The CFTC's position is that validly offered products on regulated exchanges fall under federal jurisdiction regardless of subject matter.
The outcome carries an estimated $100+ billion market at stake — the size of the U.S. legal gambling market that prediction platforms are now competing to capture.
Polymarket fee structure (effective March 30, 2026): Polymarket implemented its Fee Structure V2, applying taker fees across categories:
Fees apply a dynamic, probability-based model — peaking at 50% probability and dropping near extremes. Makers pay zero and receive rebates. Daily fee revenue crossed $1 million on April 1, 2026, up from $696,000 the prior day following the fee expansion.
Kalshi economics: Annualized revenue exceeds $1.5 billion as of May 2026, with annualized trading volume at $178 billion. Sports contracts generate an estimated $1.3 billion in annualized revenue — roughly 20% of DraftKings' estimated $6.5–6.9 billion 2026 revenue. Kalshi generated $871 million in volume on Super Bowl Sunday alone.
Both platforms have moved from zero-fee growth models to active monetization. The question of sustainable unit economics remains: Polymarket operates on-chain with near-zero infrastructure costs, while Kalshi runs a centralized order book with CFTC-registered clearing.
Polymarket settles all trades on Polygon using USDC. The platform is transitioning from Bridged USDC (USDC.e) to native USDC through a partnership with Circle announced in early 2026. Near-instant finality and negligible gas costs on Polygon keep operating costs minimal.
Discussions about potential chain migration emerged in April 2026, as Polymarket has "outgrown its original plumbing" — processing billions monthly on infrastructure originally designed for smaller-scale operations.
Polymarket's US operations (rebranded from QCEX, acquired for $112 million in mid-2025) run through a separate regulated entity: a CFTC-licensed Designated Contract Market and Derivatives Clearing Organization. The international platform remains on Polygon; the US platform operates under traditional clearing infrastructure.
Kalshi operates as a centralized exchange with its own DCM license, settling trades in USD through traditional banking rails. This dual-architecture market — one on-chain, one off-chain — represents different bets on the future of market infrastructure.
Polymarket:
Kalshi:
The ICE investment is notable for its strategic rationale. According to FinTech Weekly, the investment is "about data, not prediction markets" — ICE views real-time sentiment data from millions of prediction contracts as a complement to its existing derivatives pricing infrastructure. This positions prediction markets as information utilities rather than gambling platforms, supporting the CFTC's jurisdictional argument.
Neither platform has filed for an IPO as of mid-June 2026, though Polymarket IPO speculation persists given its valuation trajectory.
Volume: Combined prediction market monthly volume grew 2,838% from July 2024 ($810M) to April 2026 ($23.8B), according to Pew Research/The Block data.
Regulatory clarity is partial: The CFTC's June 10 proposal permits most sports contracts but bans micro-bets and injury markets. A 90-day comment period and potential legal challenges mean final rules are months away.
Jurisdictional war is unprecedented: 41 state AGs vs. the CFTC, with 20+ active lawsuits and criminal charges in Arizona. No prior test of CEA preemption against state gambling statutes at this scale exists.
Revenue is real: Kalshi's $1.5B annualized revenue and Polymarket's $1M+ daily fees demonstrate sustainable economics, though both remain in growth-investment mode.
Institutional endorsement: ICE's $2B commitment and $9B+ valuation validate prediction markets as financial infrastructure. The data-licensing angle (Polymarket Signals) may prove more valuable than trading fees.
On-chain vs. off-chain divergence: Polymarket's Polygon settlement and Kalshi's centralized clearing represent competing infrastructure models for the same asset class.
The CFTC's 267-page proposal represents the first comprehensive federal framework for an asset class that did not meaningfully exist two years ago. The regulatory question is no longer whether prediction markets will be permitted — volume has already made them systemically relevant — but which government entity regulates them and under what constraints.
The economic stakes are clear. A sector processing $24 billion monthly, backed by $2 billion from the NYSE's parent company, and generating $1.5 billion in annualized platform revenue has moved beyond experimental status. The CFTC's framework, if finalized, would establish prediction markets as a distinct regulated asset class — neither pure derivatives nor gambling, but a new category of "event contracts" with their own compliance regime.
The 90-day comment period closes in September 2026. State lawsuits will likely reach federal appellate courts by year-end. The outcome determines whether prediction markets remain a federally regulated financial product or fragment into a state-by-state licensing regime that could materially reduce the addressable market.
