Prediction Markets Face Legal Scrutiny Amid Growth

Prediction markets, led by Kalshi, are experiencing significant growth and increased valuations but are simultaneously facing heightened legal and regulatory challenges regarding their operational integrity and classification. This sector is grappling with questions concerning market manipulation and whether certain offerings constitute gambling, leading to state and federal lawsuits.

What Happened

The prediction market industry, spearheaded by Kalshi, is undergoing substantial expansion, with Kalshi reporting its most successful year to date. In July, monthly trading volumes for Kalshi exceeded $37 billion, a figure reportedly boosted by the World Cup, according to the Washington Examiner. The company is currently engaged in raising new capital, with its valuation reportedly at $40 billion, a four-fold increase from eight months prior. Despite this growth, the industry faces increasing legal challenges and regulatory scrutiny regarding its operational model and market integrity, including potential classification as gambling, which could lead to lawsuits and an eventual Supreme Court review, as reported by the Washington Examiner.

Kalshi, founded in 2018 by Tarek Mansour and Luana Lopes Lara, both MIT alumni, aims to allow trading on binary outcomes directly. The company’s business model is based on volume and trading fees, with contracts structured around yes-or-no propositions, priced between $0 and $1 to reflect event likelihood, according to the Washington Examiner. In 2020, the Commodity Futures Trading Commission (CFTC) approved Kalshi as a designated contract market, subjecting it to the Commodity Exchange Act and distinguishing it from state gambling laws, the Washington Examiner reported. However, an escalating dispute with state and tribal regulators questions whether some of these offerings constitute gambling.

Key Details

• Kalshi’s monthly trading volumes surpassed $37 billion in July, reportedly aided by the World Cup, according to the Washington Examiner.
• Kalshi is reportedly raising new capital at a $40 billion valuation, marking a four-fold increase in eight months, as stated by the Washington Examiner.
• The CFTC approved Kalshi as a designated contract market in 2020, subjecting it to federal oversight under the Commodity Exchange Act, according to the Washington Examiner.
• Donald Trump Jr. reportedly advises both Kalshi and its competitor Polymarket, with the Trump administration generally supporting these markets, while the previous administration reportedly took a more hostile stance, as noted by the Washington Examiner.
• In November 2025, Kalshi suspended ex-investment banker Mark Moran for five years and fined him $6,229.30 for trading on a market concerning his own political candidacy, citing his direct influence over the outcome, the Washington Examiner reported.
• In mid-August, “mention markets” were removed from Kalshi’s exchange amidst an active inquiry from the CFTC, according to the Washington Examiner.

Why It Matters

The rapid expansion of prediction markets, particularly Kalshi’s increased valuation and trading volumes, signifies a growing financial instrument sector. The involvement of significant Silicon Valley investors like Sequoia Capital and a16z, alongside financial institutions backing Polymarket, indicates a belief in prediction markets as a substantial new asset class and a potential tool for forecasting and risk hedging, as reported by the Washington Examiner. However, the legal challenges and regulatory inquiries concerning market manipulation and the distinction between derivatives and gambling threaten the operational framework and long-term viability of these platforms. The Washington Examiner notes that a 2024 Fed working paper, “Kalshi and the Rise of Macro Markets,” identified prediction markets as a valuable complement to existing forecast tools, highlighting their potential impact on economic forecasting.

Regulatory decisions and judicial outcomes in these ongoing disputes will likely shape the future scope and legality of prediction market offerings. This has implications for how financial instruments are classified and regulated, potentially impacting market access for both retail and institutional investors. The reported vulnerability to manipulation, as demonstrated by the Mark Moran case, raises fundamental questions about market integrity that regulators are now actively addressing, according to the Washington Examiner. The outcome of these legal and regulatory confrontations will determine the operational boundaries and public perception of this emerging financial sector.
