Recent SEC Filing Reveals Ongoing Fundraising Amid Advanced Talks for a $40 Billion Valuation and Rapidly Expanding Derivatives Markets
Prediction market operator Kalshi has sold approximately $1.12 billion in equity since April, according to a recent Form D filing submitted to the U.S. Securities and Exchange Commission (SEC) on August 25. The filing indicates that roughly $380 million remains available out of a nearly $1.5 billion total offering.
While the SEC filing does not detail specific financing rounds making up the sold equity, reports suggest the figure encompasses Kalshi’s previously announced $1 billion Series F financing. Led by Coatue in May, the Series F round doubled the company’s valuation to $22 billion, drawing participation from high-profile investors including Sequoia Capital, Andreessen Horowitz, IVP, Paradigm, Morgan Stanley, and ARK Invest. Prior to that round, Kalshi had raised $300 million at a $5 billion valuation before climbing to $11 billion.
Advanced Talks for a $40 Billion Valuation and IPO Exploration
Despite rapid valuation milestones, investor discussions have continued to push the company’s financial ceiling upward. Reports from The Information indicate that Kalshi has been engaged in advanced talks to raise at least $750 million at a staggering $40 billion valuation, with Sequoia Capital and Wellington Management discussing co-leading the transaction.
Alongside private funding discussions, Kalshi has initiated informal talks with investment banks regarding a potential initial public offering (IPO), though no formal timeline has been established.
Explosive Trading Volume and Product Expansion
Kalshi’s financial momentum mirrors massive growth in user activity and platform volume. Trading activity surged over the summer, with July volume reaching approximately $40 billion, significantly outpacing rival prediction markets like Polymarket and Polymarket US combined. Annualized revenue has reportedly climbed past $4 billion, driven heavily by sports event contracts (which account for an estimated 85% to 90% of trading volume) as well as major fixtures like the FIFA World Cup and NBA Finals.
Beyond traditional event contracts, Kalshi has aggressively expanded into new financial products. The platform introduced regulated Bitcoin perpetual futures in the United States earlier this year, quickly expanding into Ethereum and filing for products linked to XRP, Solana, Dogecoin, and other digital assets. Within two weeks of launch, crypto perpetual futures volume surpassed $5.5 billion.
Operating as a designated contract market regulated by the Commodity Futures Trading Commission (CFTC), Kalshi’s rapid growth has also drawn scrutiny. The platform continues to navigate state-level regulatory disputes and ongoing lawsuits in jurisdictions such as Illinois and New York, as state authorities contend that certain sports-linked contracts must comply with local gaming regulations.
