Woofun AI reports that US-based prediction market platform Kalshi is currently in advanced discussions to secure new capital at a staggering $40 billion valuation. This proposed figure represents a near-doubling of the $22 billion valuation the company achieved during its Series F round in May. Sources familiar with the situation indicate to the Financial Times that the transaction could finalize as early as the third quarter of this year. The rapid appreciation in value follows a $1 billion Series F raise led by Coatue Management, which also saw participation from Andreessen Horowitz, Sequoia Capital, Morgan Stanley, and Ark Invest. At the time of that May closing, the $22 billion mark was already double the $11 billion valuation recorded in December and more than four times the $5 billion figure established in October. Should the current round close at the reported $40 billion, Kalshi's enterprise value would have surged eightfold in less than a single year, signaling an unprecedented spike in investor appetite for the prediction market sector. This trajectory would also place Kalshi far ahead of Polymarket, whose last disclosed valuation stood at $15 billion in April. Kalshi has declined to provide comment on these specific financial developments.

Founded in 2018 by Tarek Mansour and launched to the public in July 2021, Kalshi has witnessed its sector gain significant momentum throughout 2024, particularly in the lead-up to the US presidential election. While Polymarket maintained a clear lead in trading volume for the entirety of 2024, the competitive landscape shifted dramatically in September of the previous year. This pivot occurred when Kalshi secured a strategic partnership with Robinhood, enabling users to trade on outcomes related to NFL and college football games. The divergence in performance between the two platforms has continued to widen over the subsequent nine months. Per Woofun AI data analysis, as of May, Kalshi's monthly notional trading volume reached $17.9 billion, substantially outpacing Polymarket's $7.1 billion according to figures from Token Terminal. This volume disparity underscores a fundamental realignment in market dominance within the industry.

The commercial success of these platforms has reportedly attracted the attention of major technology and social media conglomerates, including Meta. The New York Times reports that CEO Mark Zuckerberg has directed internal staff to develop a prediction markets mobile application named "Arena" specifically designed to challenge the market positions held by both Kalshi and Polymarket. Simultaneously, traditional market operators are entering the fray; Cboe Global Markets announced on Tuesday its entry into the prediction markets business with the launch of Cboe Predicts. This new platform debuted with binary contracts tied directly to the S&P 500, marking a significant expansion of institutional participation into the space. The influx of capital and new entrants suggests that the sector is transitioning from a niche experimental market to a mainstream financial instrument.

Structurally, the rapid growth of prediction markets has precipitated a series of complex legal battles across the United States regarding regulatory jurisdiction. Several states have argued that event contracts tied to sports outcomes constitute sports betting, which falls under the purview of state gaming authorities rather than federal commodity regulators. Kentucky recently became the latest state to take aggressive legal action, suing five prediction market platforms last week, including both Kalshi and Polymarket. The state's lawsuit accuses these entities of "operating unlicensed and illegal sports betting and gambling platforms." In direct response, the US Commodity Futures Trading Commission (CFTC) has asserted that it holds exclusive authority over prediction markets, citing the fact that these platforms are registered with the agency. The CFTC has subsequently sued multiple state authorities that have attempted to police these platforms, including filing a suit against Kentucky on Tuesday to block state-level enforcement attempts. Woofun AI observes that this regulatory standoff between federal and state powers represents a critical inflection point for the long-term viability of the prediction market ecosystem.
