Prediction market platform Kalshi has successfully closed a massive $1 billion funding round, catapulting its valuation to an astounding $40 billion, according to reports published Thursday. The latest capital injection highlights the explosive growth and rising institutional interest in prediction markets as the company aggressively expands its operational footprint beyond traditional sports betting and deeper into mainstream financial and macroeconomic markets.
The Series G financing round was co-led by prominent investment powerhouses Wellington Management and Sequoia Capital. Alongside the valuation milestone, Kalshi revealed that its non-sports prediction markets have officially surpassed $1 billion in annualized revenue, underscoring a significant shift in how users and financial entities utilize event contracts for forecasting and hedging.
The completion of the financing confirms earlier reports that first surfaced in September, when market insiders indicated that Kalshi was in advanced talks to secure a $1 billion raise at the exact same $40 billion valuation target. The swift confirmation of the round demonstrates sustained venture capital confidence in the platform, particularly coming on the heels of another massive financial milestone earlier in the year.
In May, Kalshi completed a $1 billion Series F funding round led by Coatue Management, which valued the company at $22 billion. At that time, the prediction market platform reported an annualized revenue run rate exceeding $1.5 billion, driven by surging participation and an increasingly diverse array of event contracts. User engagement and trading activity have continued to scale aggressively since then. According to data provided by Defi
Llama, Kalshi has recorded approximately $15.8 billion in trading volume over the past 30 days alone, reflecting continuous high-frequency interaction and strong liquidity across its various market sectors.
Expanding Partnerships Amid Legal Challenges
Even as Kalshi secures record-breaking institutional backing and expands its market reach, the company is navigating a complex and increasingly hostile web of regulatory scrutiny and legal battles across the United States. Despite these mounting hurdles, Kalshi has continued to forge high-profile strategic partnerships that cement its status as a core infrastructure provider for financial benchmarks and event-based forecasting.
In a major validation of its platform integrity and market utility, the National Basketball Association (NBA) named Kalshi alongside Polymarket as preferred prediction market exchanges earlier in the week. Simultaneously, S&P Dow Jones Indices announced a landmark partnership with Kalshi designed to integrate its globally recognized financial benchmarks directly into event-driven prediction markets. These agreements represent a profound institutional endorsement, bridging traditional financial market data with decentralized or alternative forecasting mechanisms.
However, these commercial triumphs arrive against a backdrop of escalating legal friction regarding the fundamental jurisdiction governing prediction markets. At the center of the dispute is an ongoing legal battle over whether Kalshi’s sports-related and event-based contracts fall under state gambling laws or federal derivatives regulations overseen by national authorities.
The jurisdictional conflict intensified last week when the state of Utah filed a lawsuit against Kalshi, arguing that its operations violated state-level gambling prohibitions. That state-level enforcement action prompted a swift and aggressive counter-response from federal regulators. On Tuesday, the US Commodity Futures Trading Commission (CFTC) filed a separate lawsuit seeking to block state enforcement actions against federally regulated derivatives platforms, arguing that federal oversight preempts individual state laws in this domain.
The dispute escalated further when Utah authorities escalated the confrontation by filing criminal charges against Kalshi and its co-founders, according to reports. The criminal filing accuses the platform and its leadership of promoting illegal gambling within the state boundaries, setting the stage for what could become a landmark legal battle over the jurisdictional boundaries of federal derivatives regulation versus state-level gaming enforcement.
As Kalshi deploys its newly acquired capital from the $40 billion funding round, the company will have to navigate these complex regulatory headwinds while continuing to scale its financial markets and cement its partnerships with major sports leagues and financial index providers.
