Kalshi Inc., the New York-based prediction market operator, has sold approximately $1.12 billion in equity through a private offering that began in early April, according to a Form D notice filed with the U.S. Securities and Exchange Commission on August 25, 2026. The filing shows the company has completed sales totaling $1,120,010,122 out of a planned offering of nearly $1.5 billion, leaving roughly $380 million still available under the same notice.

The first sale under the offering occurred on April 3, 2026. The notice was signed by Chief Executive Officer Tarek Mansour and lists 71 investors as participants. It was conducted under the Rule 506(b) exemption, with no minimum investment amount specified for outside investors and no sales commissions or finder’s fees reported.

Details of the Form D Disclosure

The filing names company directors including Luana Lopes Lara, Alfred Lin, Michael Seibel, and Matt Huang. The document does not break down the precise composition of the $1.12 billion already sold or detail the planned use of proceeds beyond standard disclosure requirements.

This private equity offering follows closely after Kalshi’s Series F round completed in May 2026. That earlier financing raised $1 billion at a $22 billion valuation and was led by Coatue Management, with participation from Sequoia Capital, Andreessen Horowitz, and other investors including IVP, Paradigm, Morgan Stanley, and Ark Invest. Some reports indicate the Form D total may incorporate amounts from the Series F or related transactions, though the filing itself does not specify.

Reports of Further Fundraising Discussions

In the months following the Series F close, Kalshi has been linked to additional capital-raising efforts. Reports from June onward described the company as seeking fresh funds, with discussions potentially involving a $750 million round that could value the business at $40 billion. Those talks have been described as involving parties such as Sequoia Capital and Wellington Management, though no final terms or closing have been confirmed in the latest disclosures.

Earlier Form D filings show a pattern of successive capital raises. A December 2025 notice reported more than $820 million sold under a similar exemption, with smaller amounts disclosed in prior years dating back to 2020.

Trading Volumes and Market Position

The capital inflows coincide with sharp increases in platform activity. Annualized trading volume reached $178 billion by April 2026, rising from roughly $5 billion a year earlier. Institutional trading volume increased 800 percent over the six months leading into that period, with sports-related contracts accounting for a substantial share of activity.

Kalshi reports holding between 90 percent and 95 percent of the U.S. prediction market and has cited annualized revenues exceeding $2 billion. The platform operates as a designated contract market under Commodity Futures Trading Commission oversight, allowing it to list event contracts tied to elections, economic indicators, sports outcomes, and other real-world events.

Co-founders Tarek Mansour and Luana Lopes Lara have positioned the company for continued expansion, with public comments pointing toward a possible initial public offering as early as 2027. The regulatory status has supported institutional participation, distinguishing the platform from certain competitors that lack equivalent U.S. clearance.

Context Within the Prediction Market Sector

The successive large raises come as prediction markets attract greater attention from institutional participants who treat event contracts as tools for hedging and risk management alongside traditional futures and options. Sports contracts have driven much of the recent volume growth, while the platform continues to broaden its product offerings and regulatory footprint across the United States.

The Form D filing provides a concrete update on capital raised to date but leaves open questions about the final size of the current offering and the specific allocation of proceeds. With approximately $380 million still available under the notice, further sales could bring the total closer to the $1.5 billion target in the coming period.
