Kalshi Soars to $40B Valuation After Fresh $1B Raise as Prediction-Market Wars Intensify

TL;DR:

• Kalshi closed a $1 billion funding round co-led by Sequoia Capital and Wellington Management, placing its private valuation at $40 billion.
• The figure represents an approximate 82% increase compared to the $22 billion recorded after its May 2026 round.
• Contracts tied to sports events contributed nearly 65% of the firm’s revenue in recent periods, amid state regulatory disputes.

New York-based prediction market operator Kalshi closed a new $1 billion capital injection, raising its valuation to $40 billion this Thursday, October 29, 2026.

This is the second $1 billion raise completed by the company in less than five months. According to the Reuters report, the round was co-led by venture capital firms Sequoia Capital and Wellington Management, with additional participation from Tiger Global Management and Dragoneer Investment Group.

This new capital allocation follows the previous Series round finalized in May 2026 led by Coatue Management, at which point the platform was valued at $22 billion. In comparative terms, the company’s historical funding records reflect a rapid escalation: in October 2025, its estimated value stood at around $5 billion, rising to $11 billion in December of that same year before reaching the level reported this week.

Founded by MIT graduates Tarek Mansour and Luana Lopes Lara, Kalshi operates under federal oversight as a designated contract market with the U.S. CFTC. Due to how it was designed, it is possible to purchase binary contracts where the price ranges between 1 and 99 cents, reflecting the implied probability that the market assigns to the outcome of a specific event.

Expansion into financial derivatives and competition with Wall Street

The plan is to expand its transactional infrastructure to compete directly with established derivatives platforms such as CME Group and Intercontinental Exchange (ICE) using the capital raised. Kalshi introduced perpetual futures contracts on cryptocurrencies and subsequently incorporated instruments tied to stock indices and precious metals after receiving technical clearances.

The roadmap outlines the rollout of perpetual contracts on single stocks, leveraged event contracts, and hedging instruments tied to compute capacity.

According to the company, operational growth underpins the interest of participating funds. Corporate data released in May reveals that annualized trading volume surged from $52 billion to $178 billion within a six-month span. Additionally, institutional counterparty activity grew 800% year-over-year. By September 2026, the platform maintained business relationships with 500 institutional entities, which accounted for roughly 25% of the overall transacted volume, excluding market makers.

The global prediction market industry recorded a transaction volume of $63 billion at the close of 2025, compared to $500 million in 2022, according to industry figures compiled in the case research.

In direct competition with Polymarket, sector reports attribute to Kalshi a market share of approximately 72% of total volume during the third quarter of 2026. This position was solidified by transaction volume originating from sports events and distribution through regulated retail brokerages.

The platform’s commercial progress coincides with legal challenges raised by local regulators across the United States. State authorities argue that contracts based on sports outcomes constitute gambling under state jurisdiction rather than derivative contracts exclusively protected by federal law.

According to available financial documentation, sports contracts accounted for nearly 65% of Kalshi’s operating revenue in certain periods, which lends material significance to the ongoing litigation. Several appellate courts have issued split decisions regarding the supremacy of federal regulation over state gambling laws. In this regard, the company’s executive leadership indicated that the final determination on this legal jurisdiction could be resolved by the U.S. Supreme Court.

Regarding a potential public listing, CEO Tarek Mansour formally ruled out an initial public offering during the course of 2026. Preliminary estimates from the management team place an eventual public listing on stock exchanges between 2027 and 2028, contingent upon the stabilization of judicial frameworks and institutional liquidity conditions.
