The prediction market industry is currently witnessing rapid growth, with platforms such as Kalshi and Polymarket leading the way in this swiftly changing environment. Kalshi, a U.S.-based prediction market, saw its notional trading volume exceed $2 billion during the week before October 2025, largely fueled by major sporting events like the MLB playoffs and NFL matchups, according to a
The National Hockey League’s recent multi-year licensing arrangement with Kalshi and Polymarket represents a notable breakthrough, making it the first major U.S. sports league to collaborate with prediction market platforms, according to a
Yet, Kalshi’s growth has raised concerns among regulators and industry stakeholders. U.S. geolocation companies, which are responsible for ensuring compliance with location-based betting laws, have expressed worries about Kalshi’s ability to operate across the country under a Commodity Futures Trading Commission (CFTC) license without employing GPS-based verification, according to
At the same time, DraftKings, a dominant name in online sports betting, continues to hold a strong market position despite the emergence of prediction markets. Since expanding into sports betting after the Supreme Court’s 2018 decision, DraftKings has secured a leading share in 28 states for sports betting and five states for i-gaming, as reported by GuruFocus. Analyst Bernie McTernan from Needham pointed to DraftKings’ sophisticated personalization and wide-ranging offerings as major advantages, indicating that most new prediction market participants are coming from unregulated areas rather than directly competing with established sports betting services.
The competitive and regulatory landscape for prediction markets is likely to become more complex as Kalshi and Polymarket continue to grow. Although the NHL partnership reflects greater mainstream acceptance, significant hurdles remain in aligning federal derivatives regulations with state gambling laws. For now, the sector’s expansion is being propelled by technological progress and institutional support, but its future will hinge on how regulators, lawmakers, and industry players address the shifting legal and ethical challenges.
