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 its May 2026 Series F figure, according to the Financial Times. Annualised revenue has crossed $2 billion and CEO Tarek Mansour confirmed early IPO discussions — though not 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. Annualised revenue has crossed $2 billion, versus approximately $1 billion for Polymarket. The valuation climb tells the year's story in compressed form: $2 billion in June 2025, $11 billion in December, $22 billion in May 2026, $40 billion targeted now. The Series F investors — 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 that a listing will not happen in 2026, with late 2027 or 2028 as the realistic window. That the IPO discussion is happening at all is a milestone: Kalshi's existence until this year was defined by its regulatory fight to establish its products were legal. That fight continues — nine US states are in active litigation — but the company is now simultaneously defending its right to operate and planning a public offering. Those two things coexist because the CFTC's legal posture strongly suggests the federal-preemption arguments will ultimately hold.
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, and institutional trading grew 800% in the six months to June 2026. These are not the numbers of a niche product — they approach the scale of mid-tier US futures exchanges. The CFTC's proposed rule, open for comment until 27 July, would formalise the regulatory regime underpinning all of it.
For UK observers, the $40 billion target is instructive about the regulatory dividend of a clear federal framework. Kalshi's entire valuation trajectory — from $2 billion to $40 billion in 12 months — traces directly to the CFTC establishing authoritative jurisdiction over prediction markets and successfully defending it in court. A UK exchange operating under equivalent FCA clarity would have the same advantage. Without that clarity, British operators cannot build the product, and British investors are watching the value creation happen in a market where they cannot participate.

Crypto.com and Novig Sue Missouri as Market Leaders Hold Back — Eighth Circuit Now in Play via Iowa
Crypto.com and Novig filed federal lawsuits on October 16 challenging Missouri's cease-and-desist orders, arguing their sports event contracts fall under exclusive CFTC jurisdiction. The suits came as Missouri's 30-day compliance window closed. Notably, the market leaders — Kalshi, Polymarket, Robinhood, and Underdog — have not sued; Missouri said it is in 'ongoing discussions' with Kalshi. The outcome is tied to the Eighth Circuit, now weighing the same question in Kalshi's Iowa appeal — the fourth federal circuit to take up the prediction market question.
Ohio Escalates Post-Sixth Circuit — Cease-and-Desist to 10 Operators, but Platforms Keep Operating
Emboldened by its Sixth Circuit win, Ohio escalated enforcement. Governor Mike DeWine and the Ohio Casino Control Commission issued cease-and-desist letters dated October 2 to 10 operators, including Polymarket and Robinhood, with an October 16 deadline and penalties up to the value gained from contracts. Kalshi was excluded because a court order already covers it. As of October 20, platforms were still operating in Ohio despite the deadline. Polymarket has sued the Commission and AG Andy Wilson; Wilson is expected to sue non-compliant operators.
Midterm Election Betting Tops $220M — Double the Entire 2024 Cycle — as Public Opposition Mounts

The 2026 cycle has more than 21,000 individual markets, up from 463 in 2024. Volume is concentrated in a few races, led by the Texas Senate contest. The growth comes despite a Reuters/Ipsos poll finding most Americans oppose using prediction markets to bet on elections.
