Kalshi Is Seeking a $40 Billion Valuation — Seven Weeks After Raising at $22 Billion
Kalshi is in talks for a new funding round at a $40 billion valuation, nearly doubling the $22 billion figure from its May 2026 Series F, according to the Financial Times. The company's annualized revenue has crossed $2 billion, and CEO Tarek Mansour confirmed the company is in early IPO discussions — though a listing will not happen before 2027. Combined Kalshi and Polymarket volume hit $44.8 billion in June, a 75% jump from May.
Kalshi is seeking a new round of outside investment at a valuation of approximately $40 billion, according to the Financial Times, just seven weeks after closing a $1 billion Series F at a $22 billion valuation. The funding round talks come alongside a public disclosure of the company's revenue trajectory: annualized revenue has crossed $2 billion, versus approximately $1 billion for Polymarket. The valuation climb tells the story of the year in compressed form: Kalshi was worth around $2 billion in June 2025, $11 billion by December, $22 billion in May 2026, and is now targeting $40 billion. The investors from the Series F — Coatue, Sequoia, Andreessen Horowitz, and Morgan Stanley — have seen their stake roughly double in value in under two months.
CEO Tarek Mansour confirmed to CNBC that the company is in early conversations about an eventual IPO but said emphatically that a public offering will not happen in 2026. Reports suggest late 2027 or 2028 as the realistic window, pending market conditions. The IPO discussion is itself a milestone: Kalshi's entire existence until this year was a regulatory fight to establish that its products were legal. That fight is not over — nine states are in active litigation — but the company is now simultaneously defending its right to operate in court and planning what a public offering might look like. Those two things coexist because the CFTC's legal posture strongly suggests the federal-preemption arguments will ultimately hold.
The combined Kalshi and Polymarket monthly trading volume for June was $44.8 billion, a 75% surge from May's $25.66 billion — driven overwhelmingly by World Cup trading. Kalshi claims more than 90% of US prediction market activity by volume. Institutional trading volume grew 800% in the six months ended June 2026. These are not the numbers of a niche product: they are approaching the scale of mid-tier US futures exchanges, which is precisely the comparison Kalshi wants analysts and potential IPO investors to make. The CFTC's proposed rule — open for public comment until July 27 — would formalize the regulatory regime that underpins all of it, converting the agency's litigation posture into codified regulation.
The $40 billion target is also a statement about competitive positioning. Polymarket reached $1 billion in annualized revenue six weeks after its US launch, which is extraordinary growth — but it is half of Kalshi's current figure. Bernstein analysts noted in a June 29 report that Kalshi owns the exchange stack and has built federally regulated infrastructure, but that it 'trails on distribution,' leaving it plausibly a target as well as an acquirer. The report named Robinhood, Coinbase, and DraftKings as potential acquirers. Mansour's IPO positioning is a direct response to that framing: a $40 billion public valuation makes a friendly acquisition harder to execute and establishes Kalshi as a standalone financial exchange rather than an asset to be absorbed into a larger consumer platform.

Kalshi's Parlays Drive Back-to-Back $5B Days — and Hand Critics Their Strongest Argument
Kalshi traded a record $5.33 billion on November 7 and $5.36 billion on November 8, with multi-leg parlay-style 'combos' making up roughly 75% of both days' volume. Its 30-day volume topped $100 billion. But the parlay dominance cuts against the platform's legal defense: parlays are a quintessential sportsbook product, and the American Gaming Association has told the Second Circuit that parlays make up about two-thirds of Kalshi's volume and should be treated as sports bets. The implied house edge on 10-plus-leg combos is around 25%, undercutting the argument that these are neutral financial instruments rather than gambling.
Cruz Bill Would Require State or Tribal Approval for Sports Contracts — a Bipartisan Legislative Threat Emerges
Senator Ted Cruz, who chairs the Senate Commerce Committee, is preparing a bill that would bar federally regulated prediction markets from offering gambling-tied event contracts, including sports, unless a state or tribal government authorizes them. It would not ban the contracts nationwide but would require platforms to obtain approval jurisdiction by jurisdiction, resembling state-by-state sportsbook regulation. The proposal arrives as Democrats take control of both chambers after the midterms, creating a potential bipartisan reckoning: a Republican committee chair and a newly skeptical Democratic majority both eyeing restrictions on a sector that had relied on federal protection.
CFTC Tells Platforms to Stop Geofencing States — Directly Colliding With State Court Orders
The CFTC issued an interpretation on November 5 of its 'impartial access' core principle, telling regulated exchanges including Kalshi and Polymarket to drop state-by-state geographic blocks within 30 days or explain why they cannot. The demand collides head-on with existing state court orders that require the platforms to geofence: Washington ordered Kalshi to geofence in August, and Michigan ordered it to use licensed geolocation to block the state in September, with a $500,000 daily fine for violations. Chairman Michael Selig framed the interpretation as a uniformity requirement. The platforms are now caught between a federal demand to unblock states and state court orders to block them.
