Summary
Compliant prediction market platform Kalshi is raising at least $750 million at a $40 billion valuation, double its $22 billion valuation from six months ago, with Sequoia Capital and Wellington Management leading the round. Simultaneously, the U.S. CFTC is reviewing mention markets on prediction platforms, highlighting regulatory challenges facing the rapidly growing industry.
Rapid Valuation Growth Driven by Strong Revenue Performance
Compliant prediction market platform Kalshi is in advanced negotiations to raise funding at a $40 billion valuation, nearly doubling its $22 billion valuation from May 2026. According to sources familiar with the matter, Sequoia Capital and Wellington Management are considering leading this round of at least $750 million in new funding.
This valuation surge reflects the explosive growth of the prediction markets industry. Kalshi's annualized revenue reached $4 billion in July, primarily driven by betting on the 2026 World Cup. Sequoia Capital recently stated that Kalshi now commands a 95% revenue share of the U.S. prediction markets sector.
Sports contracts have become Kalshi's core business, contributing over 80% of trading volume. The success of this business model has attracted attention from traditional financial institutions. For Wellington Management, which oversees $1.3 trillion in client assets, this would mark its first investment in Kalshi. Wellington is known for making private investments in companies before they go public, and its participation in this round could pave the way for Kalshi's planned 2027 initial public offering.
Just six months ago in May, Kalshi completed a $1 billion funding round at a $22 billion valuation. The doubling of valuation in such a short period demonstrates strong capital market confidence in the compliant prediction markets sector. By comparison, its main competitor Polymarket was seeking funding at a $20 billion valuation with annualized revenue of only $1.1 billion. In August, Intercontinental Exchange, the parent company of the New York Stock Exchange, invested $600 million in Polymarket at a $15 billion valuation.
New Developments in Regulatory Scrutiny
Even as Kalshi's valuation soars, the U.S. Commodity Futures Trading Commission is conducting an internal review of mention markets on prediction platforms. According to sources familiar with the situation, the CFTC first alerted Kalshi to this review several weeks ago.
Mention markets consist of contracts where traders speculate on whether specific words will be used in speeches, corporate earnings calls with analysts and investors, or television broadcasts. These markets have long been among the most controversial offerings on prediction platforms. Critics view them as easily manipulable by individuals, as speakers or commentators could deliberately use or avoid certain words to influence market outcomes.
Following the CFTC's notification of the review, Kalshi proactively removed sports-related mention market contracts. It remains unclear whether this inquiry applies only to sports-related mention markets or encompasses all mention markets regardless of topic. Mention markets reportedly saw approximately $3.3 million in trading volume, representing a relatively small portion of overall prediction market activity.
Kalshi's main competitor, Polymarket, does not offer mention markets on its CFTC-regulated U.S. exchange, potentially reflecting a more cautious approach to regulatory risk. Notably, the Financial Times reported that JPMorgan Chase terminated its banking relationship with Polymarket last year, indicating that traditional financial institutions remain cautious about compliance risks associated with prediction market platforms.
Federal Versus State Regulatory Authority Dispute
The prediction markets industry faces a fundamental legal dispute over federal versus state regulatory authority. A growing number of states argue that prediction market platforms are effectively operating illegal gambling businesses. As the federal regulator for prediction markets, the CFTC has sued multiple states in an attempt to block state-level regulatory actions.
In July, attorneys general from 44 states wrote a joint letter questioning whether the CFTC has the authority to serve as the exclusive regulator of sports-related event contracts found on exchanges. The core of this dispute centers on whether prediction markets should be treated as federally regulated financial derivatives or regulated by individual states like sports betting.
Kalshi has called this dispute politicized, but this regulatory uncertainty is influencing development strategies across the industry. UK-based prediction market platform Smarkets is adopting a dual-track strategy to navigate this landscape. Founded in 2008, the company has over $60 billion in lifetime trading volume and has collected over $1.2 billion in volume this year.
Smarkets filed for a license with the CFTC in March while simultaneously applying for sportsbook operating permits in Illinois, Iowa, and Michigan. Company founder Jason Trost explained that the dual-track approach stems from legal uncertainty about whether the CFTC has federal preemption. He added that, like Kalshi and Polymarket, sports contracts also drive the majority of Smarkets' volume.
The company currently operates a betting exchange in the UK and also has operations in Ireland, Malta, Sweden, and Indiana in the United States. This international presence provides Smarkets with valuable experience navigating different regulatory frameworks, which could prove advantageous as it seeks to expand its U.S. footprint.
Broader Implications for the Financial Services Ecosystem
The rapid growth and evolving regulatory landscape of prediction markets carry significant implications for the broader financial services ecosystem. The dispute over regulatory authority highlights the challenges that emerge when innovative financial products do not fit neatly into existing regulatory categories.
For digital asset custody and wallet service providers, the rapid development of prediction markets presents both new business opportunities and compliance challenges. As prediction platform trading volumes grow, so does the demand for secure, compliant fund custody and settlement services. However, regulatory uncertainty requires service providers to closely monitor regulatory developments while supporting innovation, ensuring services align with evolving compliance requirements.
The involvement of major institutional investors like Sequoia Capital and Wellington Management signals growing mainstream acceptance of prediction markets as a legitimate asset class. However, the reported debanking of Polymarket by JPMorgan Chase illustrates that traditional financial institutions remain divided on the risk profile of these platforms.
Kalshi recently announced that Jeff Bandman, the attorney who helped the company obtain its CFTC-regulated exchange license in 2020, will return to serve as CEO of Kalshi Prime. Kalshi Prime serves customers of the company's margin perpetual futures business. This appointment may reflect the company's intention to strengthen compliance management while expanding its business scope.
Industry Outlook and Compliance Challenges
The prediction markets industry currently exists at the intersection of rapid growth and regulatory uncertainty. On one hand, Kalshi's soaring valuation and revenue growth demonstrate strong market demand for these innovative financial products. On the other hand, intensifying regulatory scrutiny and the federal-state authority dispute indicate that the industry's compliance framework is still taking shape.
The development trajectory of the prediction markets industry illustrates that balancing financial innovation with regulatory compliance remains an ongoing process. Kalshi's planned 2027 IPO could serve as an important litmus test for the industry's maturity. Before then, industry participants must navigate regulatory challenges while pursuing growth, establishing sustainable compliance frameworks that can withstand evolving regulatory requirements.
The mention markets review by the CFTC demonstrates that regulators are taking a granular approach to examining specific product offerings within prediction markets. This level of scrutiny suggests that platforms cannot simply rely on obtaining a general operating license but must ensure that each product type meets regulatory standards and does not pose unacceptable risks of manipulation or other market integrity concerns.
For international platforms like Smarkets seeking to enter the U.S. market, the dual-track approach of pursuing both federal CFTC licensing and state-level permits represents a pragmatic response to regulatory uncertainty. However, this strategy also highlights the complexity and cost of compliance in a fragmented regulatory environment.
The prediction markets industry's experience offers broader lessons for emerging financial technologies. Regulatory clarity often lags behind innovation, and companies must be prepared to adapt their business models and compliance approaches as regulatory frameworks evolve. The involvement of experienced legal and compliance professionals, such as Jeff Bandman's return to Kalshi, underscores the importance of deep regulatory expertise in navigating these challenges.
As the industry continues to mature, the resolution of key regulatory questions including the federal-state authority dispute and the permissibility of specific product types like mention markets will significantly shape the competitive landscape and determine which business models can succeed in the long term. For now, the combination of strong investor interest and active regulatory engagement suggests that prediction markets will remain a dynamic and closely watched sector of the financial services industry.
