May 21, 2026 — Paul Atkins, Chairman of the U.S. Securities and Exchange Commission (SEC), issued a public notice seeking feedback on "prediction market ETFs" and other novel fund products. This move follows a series of prediction market ETF filings—Bitwise submitted several ETFs under the PredictionShares brand in February, tracking outcomes of events such as the U.S. presidential election, while Roundhill Investments and GraniteShares have also filed similar applications. Atkins stated, "New products bring new challenges," emphasizing that the SEC requires additional time and public input to evaluate the operational mechanisms and potential impacts of these products. As a result, related approvals have been delayed.
From a product logic perspective, prediction market ETFs are essentially structured products built on a basket of event contracts. Unlike traditional index ETFs, which track stocks or bonds, these ETFs are underpinned by binary contracts linked to specific event outcomes—such as elections, economic data releases, or sports results. For everyday investors, this means that they can gain exposure to prediction markets—previously accessible only through specialized platforms—directly via their brokerage accounts. This represents a step toward democratizing financial tools. However, this approach of "packaging novel assets into traditional product structures" has prompted regulators to proceed with extra caution. It raises questions not only about the applicability of securities laws but also about the jurisdictional overlap with the Commodity Futures Trading Commission (CFTC).
How Prediction Markets Are Evolving from the Fringe to Financial Infrastructure
Over the past 18 months, prediction markets have grown from a niche topic within the crypto community to one of the industry’s key use cases, with market growth far outpacing most analysts’ expectations. By March 2026, monthly trading volume in prediction markets had reached $25.7 billion. Bernstein, an investment firm, projects that total prediction market trading volume for 2026 will hit $240 billion—a 370% increase over 2025. With an estimated compound annual growth rate of about 80%, the market could surpass $1 trillion by 2030.
Even more noteworthy is the market’s structural shift. User activity is moving away from one-off bets on major events toward high-frequency, small-value trades centered on news, macro trends, and crypto asset outcomes. According to Messari, Polymarket’s daily active users climbed from 48,611 on the 2024 U.S. election day to 78,909, while the share of non-political markets rose from 38% in 2024 to 80%. This diversification suggests prediction markets are breaking free from an election-driven narrative and embedding themselves within a broader financial information ecosystem.
How Regulatory Dynamics Are Defining the Boundaries of Prediction Markets
The SEC’s request for public comment is not an isolated event—it marks a pivotal moment in U.S. regulatory focus on prediction markets. Around the same time, the CFTC’s regulatory approach has become clearer. In May, Polymarket submitted a self-certification filing to the CFTC, aiming to launch "combinatorial outcome contracts" (parlay bets) on sports events in the U.S., with an expected launch no earlier than May 21. This self-certification process means the platform is notifying the CFTC of its intent to launch the product, rather than seeking explicit approval.
Meanwhile, insider trading risks have emerged as one of the most sensitive regulatory topics. On March 24, 2026, roughly 15 minutes before President Trump announced a suspension of hostile actions against Iran, the market saw over $500 million in unusual crude oil futures trades. The White House Office of Administration sent an email to all staff the next day, explicitly warning against using non-public government information to place bets on platforms like Polymarket or Kalshi. This incident thrust prediction market insider trading into the spotlight. In response, both Kalshi and Polymarket announced tightened insider trading rules on their platforms that same day.
Jurisdictional battles between federal and state authorities are also heating up. Minnesota became the first U.S. state to ban prediction markets, prompting the White House to file a lawsuit seeking to overturn the ban. At the same time, House Financial Services Committee Chairman French Hill stated that Congress will not rush to pass prediction market-specific legislation, noting that many lawmakers "lack a basic understanding" of the CFTC and SEC’s roles under the current regulatory framework. He advocates allowing the CFTC and SEC to exercise oversight within their existing authorities for now.
Why Capital Markets Are Betting Big on Event Contracts
The surge of capital into prediction markets is a clear indicator of the sector’s move toward the mainstream. In October 2025, Intercontinental Exchange (ICE) made a $2 billion strategic investment in Polymarket, pushing its post-investment valuation to $9 billion. Just days later, Kalshi announced a $300 million funding round at a $5 billion valuation. Valuations continued to climb rapidly: in November 2025, Kalshi raised $1 billion at an $11 billion valuation, while Polymarket began a new funding round in 2026 targeting a valuation of approximately $15 billion.
This influx of capital reflects institutions’ reassessment of prediction markets as a new form of financial data infrastructure. As analysts have noted, the emergence of clear federal-level regulatory frameworks is one of the three core structural drivers of industry growth. When regulators classify prediction markets as "federally regulated" rather than "state-level gambling," the sector’s role as financial infrastructure gains institutional legitimacy.

How Far Is the ETF Approval Path Post-SEC Consultation?
The SEC’s public consultation on prediction market ETFs essentially mirrors its cautious approach to spot crypto ETFs. Bloomberg Senior ETF Analyst Eric Balchunas believes the SEC is still "struggling" with how to handle this new asset class and will only open the approval process once it feels "comfortable" with the product.
For applications like Bitwise’s PredictionShares series, the core challenge lies not in the ETF product structure itself. As registered funds under the Investment Company Act of 1940, these products already have robust legal frameworks for disclosure, asset custody, and liquidity management. The real issue is how to define the underlying event contracts. If these contracts are classified as "futures contracts" or "swaps," issuers may face additional compliance requirements from the CFTC. Coordination between regulatory agencies will be a key variable in determining the approval timeline for prediction market ETFs. In early May, SEC Commissioner Hester Peirce expressed a relatively favorable view of prediction market business models but clarified that no final rules have been announced.
How the Compliance Path for Event Contracts Is Reshaping Asset Classes
From a broader perspective, the push for prediction market ETFs signals that event contracts are entering an institutionalized phase as a new asset class. This aligns with the ongoing wave of ETF innovation in recent years—from the approval of spot Bitcoin ETFs to the rise of actively managed ETFs, and now, prediction market ETFs. The boundaries of the U.S. ETF market are expanding into more complex structured products.
For investors, prediction market ETFs transform event contract exposure—previously requiring specialized knowledge and separate accounts—into standardized products accessible through regular brokerage accounts. This not only lowers the barrier to entry, but more importantly, integrates the market’s collective judgment on future event probabilities into the traditional financial information flow.
Of course, this evolution comes with significant risks. Prediction markets rely on robust event settlement mechanisms. The SEC will undoubtedly demand higher compliance standards for dispute resolution, authoritative outcome verification, and anti-manipulation safeguards. Additionally, if these products are approved, they may face ongoing tensions between state gambling regulations and federal commodity trading laws—as evidenced by Kalshi’s legal battles in several state courts.
Conclusion
The SEC’s call for public input on prediction market ETFs marks a turning point for event contracts, moving them from the "wild west" growth phase on platforms like Polymarket toward institutionalization under the traditional ETF framework. Regulators must address not only how to fit event contracts within existing securities laws, but also how to delineate jurisdiction among agencies and establish effective investor protections alongside product innovation. Over the next six months, the close of the public comment period, the SEC’s guidance, and any potential approval decisions will be pivotal in determining whether this sector can truly transition "from the fringe to the mainstream."
