Kalshi is in talks to raise fresh capital at a $40 billion valuation — nearly double what it was worth just weeks ago — a trajectory that would have seemed improbable less than a year ago when the prediction market platform carried a $5 billion price tag. The Financial Times first reported the discussions on Wednesday, citing people familiar with the matter, and the speed of Kalshi’s ascent has turned heads across Wall Street and Silicon Valley alike.
Summary
Key takeaways
- Kalshi is seeking a $40 billion valuation in new financing, almost doubling its $22 billion valuation from its May 2026 Series F round.
- The new funding round could close as early as Q3 2026, according to the Financial Times.
- Kalshi’s valuation has grown roughly eight-fold since October 2025, when it stood at $5 billion.
- CEO Tarek Mansour confirmed IPO discussions are underway but said a public debut will not happen before 2027.
- Kalshi reported $17.9 billion in notional monthly trading volume in May 2026, more than double Polymarket’s $7.1 billion.
Kalshi’s Ambitious Valuation and Fundraising Plans
The numbers alone tell a remarkable story. In October 2025, Kalshi raised $300 million in a Series D round at a $5 billion valuation. By May 2026, a $1 billion Series F — led by Coatue Management and joined by Andreessen Horowitz, Sequoia Capital, Morgan Stanley, and Ark Invest — valued the company at $22 billion. Now, within weeks of that close, Kalshi is reportedly in discussions that would peg its worth at $40 billion.
That kind of compression — three major valuation milestones in under a year — reflects something deeper than typical startup momentum. It signals that institutional capital views prediction markets not as a niche experiment but as a durable financial infrastructure worth betting on at scale.
The new round could close as early as the third quarter of 2026. Kalshi declined to comment on the report.
IPO on the Horizon, but Not Yet
CEO Tarek Mansour confirmed on Wednesday that the company is weighing a public market debut, though he made clear it is not imminent. “A company of our financial profile with the rate of growth that we’re seeing, that sort of conversation has to happen,” Mansour said during a CNBC appearance. He added that an IPO would not take place before 2027.
Separately, The Information reported last week that Kalshi has surpassed $2 billion in annualized revenue and has begun early conversations with investment banks about a potential listing. That financial backdrop makes the $40 billion valuation target less speculative and more grounded — though the gap between a fundraising conversation and a public offering remains wide.
Market Leadership and Competition
Kalshi now leads the prediction markets sector by a significant margin, both in valuation and trading activity. In May 2026, Kalshi recorded $17.9 billion in notional monthly trading volume. Polymarket, its closest rival, registered $7.1 billion over the same period, according to Token Terminal figures. The Block’s data dashboard shows the gap has continued widening into June, with Kalshi attracting $21.1 billion in volume so far this month against approximately $9.7 billion combined for Polymarket and its U.S. platform.
The competitive reversal is worth noting. Polymarket dominated transaction volumes through much of 2024, driven heavily by political election activity. Kalshi’s surge began around September 2025, accelerated by its strategic partnership with Robinhood to offer sports outcome contracts. That move pulled in a broader retail audience and gave Kalshi a structural edge that has since compounded.
Two Very Different Business Models
The contrast between Kalshi and Polymarket goes beyond market share. Kalshi operates as a federally supervised exchange under the Commodity Futures Trading Commission, giving it a regulated status that carries both constraints and credibility. Polymarket, by contrast, runs on blockchain technology and settles transactions in digital currency — a model that offers flexibility but creates friction with U.S. state regulators.
That structural difference matters enormously for institutional investors and for anyone eyeing a future IPO. A federally regulated platform can engage with mainstream financial partners, pension funds, and asset managers in ways that a blockchain-native competitor cannot. Polymarket was last reported to be seeking funding at a $15 billion valuation — itself a significant number, but one that trails Kalshi’s latest target by $25 billion.
Regulatory Challenges and Legal Disputes
Kalshi’s rapid growth has not gone uncontested at the state level. Kentucky state authorities recently filed legal proceedings against five prediction market operators, naming both Kalshi and Polymarket, alleging the platforms operate unlicensed sports gambling services. The action is part of a broader pattern of state-level resistance to prediction markets as the sector scales.
The federal response has been swift. The US Commodity Futures Trading Commission filed suit against Kentucky on Tuesday, asserting that it — not state gambling authorities — holds exclusive jurisdiction over platforms like Kalshi. Kalshi itself also sued the state of Illinois over legislation that would require prediction market platforms to obtain a state license and pay a 0.2% charge on digital asset transactions involving Illinois customers.
These legal skirmishes reflect a fundamental tension in American financial regulation: who gets to decide what counts as gambling versus what counts as a futures contract? The CFTC’s aggressive posture suggests federal regulators are not prepared to cede ground. How courts ultimately resolve that question will shape not just Kalshi’s operating environment, but the entire prediction markets industry.
A Crowded Field Getting Bigger
The competitive pressure is not coming only from Polymarket. Meta’s Mark Zuckerberg has reportedly directed his team to develop a competing prediction markets application called “Arena,” according to the New York Times. Cboe Global Markets, one of the largest exchange operators in the world, entered the space this week with the launch of “Cboe Predicts,” featuring binary contracts linked to the S&P 500. These are not marginal players testing the waters — they are established institutions with distribution, capital, and regulatory relationships.
For Kalshi, the arrival of well-resourced incumbents cuts two ways. On one hand, it validates the prediction markets thesis and could expand the addressable market. On the other, it introduces competition that a $40 billion valuation will need to justify through sustained volume growth and product differentiation. The window in which Kalshi can claim first-mover advantage as a regulated U.S. exchange is narrowing, which may explain why a fresh capital raise — and eventually a public offering — is accelerating on the company’s timeline.
