Kalshi hits US$22 billion valuation as trading volume rises 800% in six months
Prediction market Kalshi has reported a US$1 billion Series F round led by investment firm Coatue, taking it to a US$22 billion valuation.
Investment firms Sequoia Capital, Andreessen Horowitz, IVP, Paradigm, Morgan Stanley, and ARK Invest also participated.
Along with announcing the results of the funding round, Kalshi reported that trading volume on its platform had risen 800% over the past six months, accounting for 90% of US prediction market activity.
In April alone, trading volume hit US$178 billion, a massive feat compared to the previous year’s figure of US$5.5 billion.
In a statement, Kalshi said it plans to direct the new capital toward hedge funds, asset managers, proprietary trading firms, and insurance companies. It added that it also intends to expand its product line through deeper broker integrations and new risk products.
“Kalshi is building the leading platform for trading in real-world events,” said Philippe Laffont, Founder of Coatue. “Consumers have already embraced it, and we believe institutions will follow.”
“There are few categories in recent history that have scaled this quickly outside of AI,” said Tarek Mansour, Co-Founder and Chief Executive of Kalshi. “Event contracts could become a trillion-dollar market, and we’re still in the early stages of that transition.”

The Backstory
Why this matters now
Kalshi’s leap to a US$22 billion valuation underscores how quickly event contracts have broken out of a niche corner of finance into a scaled, mainstream product. The company says monthly activity now accounts for the vast majority of U.S. prediction market trading, and the fresh capital signals a bet that institutions will turn price signals on real‑world events into a core risk tool. This backstory tracks how Kalshi got here: a rapid funding cadence, sharp volume spikes around cultural and sports moments, a regulatory gauntlet, and intensifying rivalry with crypto‑native and retail‑heavy peers.
Regulatory headwinds shape the runway
Kalshi’s growth has played out against a persistent policy debate over whether event contracts resemble federally regulated derivatives or consumer wagering. The company secured court wins to list election markets, but it has operated amid pushback from state and federal voices. In a recent chapter, Kalshi hit a US$2 billion valuation after a funding round led by Paradigm while facing a coalition of 36 attorneys general that opposed its expansion. The case for these products hinges on their use as hedges for business outcomes and economic releases, while critics warn of backdoor gambling risks and potential for manipulation.
Sports‑linked markets have drawn special scrutiny given integrity concerns. During college basketball season, the NCAA pressed for limits and looked to the Commodity Futures Trading Commission for a timeout on markets tied to student‑athlete events. That pressure crescendo is detailed in Kalshi hits March Madness record with US$800 million traded, where the association warned about unprotected prediction venues and student safety. The CFTC updated guidance but held off on public action at that point, leaving a cloud of uncertainty even as trading accelerated.
Spikes around cultural moments fuel growth
Kalshi has used major live events to convert casual curiosity into trading habit. The platform reported over US$1 billion Super Bowl trading volume in a single day as users piled into outcomes tied not just to the game but also entertainment segments. That performance vaulted daily records and showcased breadth beyond politics and macro data. It also exposed operational and compliance stress tests: surging traffic slowed some deposits and raised questions about insider knowledge in ad‑related markets. In response, Kalshi expanded surveillance and enforcement, saying it applies exchange‑style rules and had conducted more than 200 investigations over the prior year.
The sports calendar became a proving ground again in March. In the opening days of the NCAA tournament, Kalshi set fresh highs with more than US$800 million traded during the first weekend, nearly double the volume in all three weeks the prior year. A branded billion‑dollar bracket promotion amplified consumer attention, while Dune data at the time showed total handle topping US$3.4 billion for the week with basketball contributing almost half. The contrast to traditional sportsbooks was stark: the American Gaming Association expected far smaller revenue pools from March Madness betting compared with the notional trading power of event contracts, highlighting a structural difference between speculation, hedging, and house take rates.
Capital raises turn into market share
Kalshi’s valuation ascent has tracked a brisk series of financings and a land grab for liquidity. The company hit a US$5 billion valuation after a Series D and forecasted a rapid ramp in cumulative trading to US$50 billion. It emphasized global reach and deeper broker integrations to pull in more professional flow. In that period, it also overtook crypto‑based rival Polymarket by monthly share, aided by larger fiat on‑ramps and growing institutional comfort with regulated structures.
The rivalry intensified as both platforms logged record activity. A joint surge in November saw Kalshi and Polymarket hit a combined US$10 billion in monthly volume, fueled by retail engagement and a steady news cycle. Polymarket secured prominent distribution partnerships and an investment from the New York Stock Exchange’s parent, which the coverage said placed the rival at an US$8 billion valuation. Kalshi, meanwhile, doubled its own price tag in successive rounds and then moved far beyond that threshold. The divergence suggests investors are valuing Kalshi’s regulated posture and traction with U.S. users even as both firms benefit from the same macro tailwinds of election season, economic releases, and pop‑culture catalysts.
The earlier US$2 billion round also marked a signaling moment: backing from crypto‑savvy funds and market‑structure veterans indicated a bet that event contracts would sit alongside options and futures as instruments for price discovery. Subsequent rounds layered in blue‑chip venture and crossover capital that often leads institutional adoption. That capital stack is part of why the new funds are pointed at hedge funds, asset managers, proprietary trading firms, and insurers, who prize tight spreads, reliable clearing, and robust surveillance.
Institutional courtship meets compliance demands
Winning institutional flow requires more than headline volumes. Funds want depth, clear rulebooks, predictable margining, and confidence that information asymmetries are policed. Kalshi’s actions ahead of the Super Bowl — expanding surveillance and enforcement and asserting exchange‑style standards — were aimed at those concerns. The push toward “new risk products” and “deeper broker integrations” aligns with how professional users access markets: through APIs, prime brokers, and tools that let them model exposure across rates, commodities, and now discrete events such as CPI prints, Fed meetings, or regulatory decisions.
Retail momentum still matters. November’s record US$10 billion combined month for Kalshi and Polymarket reflected a flywheel of news and user acquisition. But the strategic pivot is clear: institutional adoption can stabilize volumes beyond headline cycles and widen the set of tradable outcomes. If event contracts become standard hedges — for example, a media company offsetting box‑office risk or an insurer hedging catastrophe‑related policy triggers — liquidity deepens and the platforms’ economics improve.
What’s at stake next
The stakes are regulatory, commercial, and cultural. Regulators must reconcile how to oversee markets that price everything from GDP revisions to halftime performers. Universities and sports bodies will keep pressing for limits on student‑athlete‑linked markets, as highlighted in the NCAA’s appeal to the CFTC. Platforms must keep proving they can detect and deter insider trading in event‑driven contexts, a point Kalshi emphasized in its Super Bowl recap.
Commercially, the race is to professionalize product, not just popularize it. Early consumer spikes — from US$1 billion Super Bowl days to March Madness records — built brand and liquidity. The next leg depends on whether institutions treat event contracts as a distinct asset class. Kalshi’s rise to multibillion‑dollar valuations across successive rounds — from US$2 billion to US$5 billion and beyond — reflects that wager. If adoption broadens and rulemaking clarifies, the category could shift from curiosity to core allocation, with ripple effects across hedging, forecasting, and even how the public interprets probability in the news cycle.
