"The CFTC will no longer sit idly by while overzealous state governments undermine the agency's exclusive jurisdiction over these markets." — Michael Selig, Chairman, U.S. Commodity Futures Trading Commission
Prediction markets have exploded from a crypto-native curiosity into the most contested financial product in America. Polymarket shattered its own records in February 2026 with $7 billion in monthly trading volume and a $425 million single-day peak. Kalshi now clears over $1 billion per week across 3,500+ markets. And as of this week, both Nasdaq and Cboe have filed with the SEC to launch their own binary event contracts — signaling that Wall Street's largest exchanges believe prediction markets are not a fad, but a permanent asset class.
Yet beneath the volume records lies a three-front war: federal regulators asserting exclusive jurisdiction, more than a dozen states filing lawsuits and cease-and-desist orders, and crypto-native platforms fighting to preserve the decentralized model that started it all. The outcome will determine not just who profits from prediction markets, but whether a product born on Ethereum ends up fully absorbed by traditional finance — or whether DeFi retains a structural role in the most important new market of the decade.
This report maps the money flows, regulatory fault lines, and economic sustainability of the prediction market sector as it crosses from experiment into institution.
The 2024 U.S. presidential election was prediction markets' proof-of-concept moment. Polymarket processed billions in volume as its markets outperformed polls, pundit forecasts, and traditional probability models. But the real story of 2025-2026 is what happened after the election: volumes didn't collapse. They accelerated.
Polymarket's trajectory tells the story:
Polymarket's volume is no longer election-dependent. Geopolitical events have become the primary driver, with a single U.S.-Iran conflict contract attracting over $529 million in trading volume. Sports markets, daily index predictions, and crypto price markets now generate consistent baseline activity.
Kalshi has matched this trajectory on the regulated side:
The combined picture: prediction markets are no longer a niche DeFi experiment. They are a multi-billion-dollar industry with institutional backing, recurring revenue, and a user base that trades daily — not just during elections.
The most consequential development of the past week is not another volume record. It is the simultaneous entry of America's two largest options exchanges into the prediction market business.
Nasdaq's filing (March 2, 2026): Nasdaq submitted a proposal to the SEC for "Outcome Related Options" — binary yes-or-no contracts linked to the Nasdaq-100 index and its micro version. Contracts would trade between $0.01 and $1.00, with pricing fluctuating based on the perceived probability of a defined outcome. Settlement is binary: $1 if the condition is met, $0 if not. The structure directly mirrors Polymarket's probability-based mechanics, but wrapped in SEC-regulated exchange infrastructure.
Cboe's filing (February 2026): Cboe filed to relaunch binary options on regulated U.S. exchanges, targeting a Q2 2026 launch for "all-or-none" styled contracts focused on financial and economic events. Cboe's contracts would carry full clearinghouse guarantee, position limits, real-time surveillance, and margin efficiency — a deliberate contrast to the unregulated offshore model.
Why this matters for the crypto-native model: These filings represent the clearest signal yet that traditional finance views prediction markets as a permanent product category, not a speculative fad. But they also represent a direct competitive threat to Polymarket and other DeFi-native platforms:
| Feature | Polymarket | Kalshi | Nasdaq/Cboe (proposed) | |---------|-----------|--------|----------------------| | Regulator | CFTC (contested) | CFTC (approved DCM) | SEC | | Settlement | On-chain (Polygon) | Off-chain (centralized) | Exchange clearinghouse | | Market access | Global (non-U.S.) | U.S. only | U.S. institutional + retail | | Asset types | Any event | Events + sports | Financial indices | | Valuation | $11.6B | ~$11B | Part of exchange conglomerates |
The institutional adoption pipeline extends beyond exchanges. Tradeweb Markets and Kalshi announced a strategic partnership on February 19, 2026, to distribute Kalshi's prediction market data and analytics to institutional investors through Tradeweb's electronic trading platform. Bitwise Asset Management has filed for six "PredictionShares" ETFs providing exposure to 2026 and 2028 U.S. election outcomes through swap agreements referencing CFTC-regulated event contracts.
A Coalition Greenwich study from January 2026 found that 43% of U.S. buy-side and sell-side professionals now hold a favorable view of prediction markets' role in the financial system. Among proprietary trading firms, 10% are already trading prediction contracts and 35% plan to, with activity highest among U.S. firms where 75% of respondents are either trading or intend to.
The prediction market sector is caught in a jurisdictional collision that has no clear precedent in American financial regulation.
The federal position: CFTC Chairman Michael Selig, confirmed in late 2025, has made prediction markets a flagship priority. On January 29, 2026, he outlined a four-part regulatory agenda: (1) create a federal framework for prediction market regulation, (2) establish standards for tokenized assets as collateral, (3) onshore overseas perpetual futures, and (4) withdraw prior restrictive proposals. Selig filed an amicus brief in support of Crypto.com in its Nevada legal battle and publicly stated the CFTC would intervene against state "encroachment."
The state offensive: More than a dozen states have initiated legal action against prediction market platforms. Tennessee's Sports Wagering Council sent cease-and-desist orders to Kalshi, Polymarket, and Crypto.com. Connecticut issued similar orders to Robinhood, Kalshi, and Crypto.com in December 2025. Nearly 50 active legal cases are pending across the country. The core argument: these platforms are running unlicensed sports betting operations disguised as event contracts.
Polymarket's counterattack: On February 10, 2026, Polymarket filed a federal lawsuit against Massachusetts Attorney General Andrea Campbell and state gaming regulators, arguing that the threat of enforcement is "immediate and concrete" and that event contracts fall under exclusive CFTC jurisdiction.
The industry coalition: To combat the state offensive, major prediction market operators formed the Coalition for Prediction Markets — a lobbying group led by Crypto.com with members including Coinbase, Kalshi, Robinhood, and Underdog. This coalition represents an unusual alignment between crypto-native and TradFi players united by a common regulatory threat.
The SEC dimension: Nasdaq and Cboe's filings add a third regulatory layer. Their binary contracts would fall under SEC jurisdiction, not the CFTC — creating a potential interagency coordination challenge. As SEC Chairman Paul Atkins described prediction markets as a "huge issue," the boundary between securities-based binary options and commodity event contracts remains undefined.
The regulatory outcome has direct economic consequences. If states prevail, the U.S. market fragments into 50 different regulatory regimes. If the CFTC prevails, crypto-native platforms gain legal cover but must accept federal oversight. If the SEC carves out its own lane, Wall Street incumbents gain a structural advantage.
Understanding the economics of prediction markets requires tracking where value accrues and who bears the costs — a framework consistent with the broader analysis of blockchain economic sustainability.
Revenue composition:
The subsidy question: Polymarket's $2.3 billion in total funding (including the $2B ICE strategic round) against an unclear revenue profile raises the same sustainability questions that characterize much of the blockchain ecosystem. At an $11.6 billion valuation, the company needs to demonstrate a path to revenues that justify the capital invested — or risk becoming another venture-subsidized platform that captures attention but not durable economic value.
Kalshi's $260 million revenue on $44 billion notional volume is a more legible business model, but the 89% sports concentration creates dependence on a market category under direct legal attack from state regulators and tribal gaming interests.
Infrastructure costs: Polymarket settles on Polygon, paying minimal on-chain fees but relying on centralized order book infrastructure. Kalshi operates fully off-chain. The exchange incumbents (Nasdaq, Cboe) would leverage existing clearing infrastructure, giving them structural cost advantages at scale.
The value capture shift: As prediction markets mature, the economic pattern mirrors what has occurred in other crypto-native innovations — DeFi lending, DEX trading, stablecoin issuance. The crypto ecosystem proves the concept and absorbs the regulatory risk. Traditional finance then enters with superior distribution, regulatory standing, and institutional trust. The question is whether the crypto layer retains meaningful value — or becomes a research and development lab for Wall Street's next product.
The prediction market sector in March 2026 presents a paradox: it has never been larger, better capitalized, or more institutionally validated — and it has never faced more existential legal risk. The simultaneous entry of Nasdaq and Cboe, combined with Polymarket's $7 billion monthly volumes and Kalshi's $260 million revenue, confirm that binary event contracts are a permanent financial product. But the three-front regulatory war — federal vs. state vs. SEC — means the market's structure, participants, and geographic distribution remain fundamentally unsettled.
For the crypto ecosystem, prediction markets offer a familiar lesson. Polymarket's Polygon-based settlement and permissionless market creation proved the concept, attracted billions in volume, and forced traditional finance to respond. But as ICE invests $2 billion, Nasdaq files for binary options, and Kalshi partners with Tradeweb, the value capture is shifting from the crypto-native builders to the regulated incumbents.
The most consequential outcome for Web3 is not whether prediction markets succeed — they already have. It is whether the decentralized infrastructure that enabled them retains any meaningful role in the industry it created, or whether this becomes the clearest case study yet of crypto as Wall Street's free R&D department.
