Kalshi has confirmed a $1 billion Series F led by Coatue Management, lifting its valuation to $22 billion and cementing its position as the dominant U.S. prediction-market platform. The raise marks a sharp institutional pivot into event-based trading, with investors betting that contracts tied to real-world outcomes can become a major new derivatives category.
The funding comes after Kalshi doubled its valuation from $11 billion in December 2025 to $22 billion in just five months. Alongside Coatue, the round included Sequoia Capital, Andreessen Horowitz and Morgan Stanley, giving the company a heavyweight investor base as it pushes deeper into institutional markets.
Institutional Volume Drives the Repricing
Kalshi said institutional trading volume climbed 800% over six months, taking annualized trading volume from $52 billion to $178 billion. The company also said annualized revenue has moved past $1.5 billion, reflecting how quickly event contracts are moving from retail curiosity to institutional product line.
The company now claims more than 90% of U.S. prediction-market activity and the majority of global volume. That scale gives Kalshi a liquidity advantage over rivals, especially as larger traders require deeper order books, better execution tools and more formal broker connectivity.
Philippe Laffont, founder of Coatue, said consumers have already embraced prediction markets and that institutions are expected to follow. Kalshi CEO Tarek Mansour framed the opportunity even more broadly, arguing that event contracts could become a trillion-dollar market while institutional adoption remains in its early stages.
Kalshi plans to use the capital to accelerate institutional onboarding, launch block trading, deepen broker integrations and develop new “risk products.” Those priorities show the company is building for derivatives-style workflows, not just retail betting on public events.
Regulatory Pressure Remains the Core Risk
Kalshi’s rapid growth has also drawn intensifying scrutiny from state authorities. Regulators in Massachusetts, New Jersey, Arizona, Nevada, Illinois and Connecticut have raised challenges or taken enforcement actions, arguing that some contracts resemble unlicensed gambling.
Kalshi maintains that it operates as a federally regulated exchange under CFTC oversight, placing the dispute at the intersection of derivatives law and state gambling rules. The company has hired former Obama staffer Stephanie Cutter as a policy adviser to support Washington relations and compliance strategy.
The regulatory fight matters because state-level restrictions could slow product rollout or raise litigation costs, even as institutional demand accelerates. For trading firms and treasuries evaluating event-contract exposure, better liquidity must be weighed against jurisdictional uncertainty and heightened oversight.
Kalshi’s rise has outpaced competitors such as Polymarket, which previously raised $300 million at a $5 billion valuation, while some private estimates have placed its target higher. Analysts cited in company coverage project prediction-market volumes of about $240 billion in 2026, with the sector potentially expanding toward $1 trillion over time.
The Series F signals deeper liquidity, broader product design and more formal market infrastructure around event contracts. If Kalshi succeeds with block trading and broker integrations, prediction markets could become easier to access through traditional trading workflows.
The next phase will depend on whether legal clarity can keep pace with market growth. Kalshi’s new capital should expand institutional flows and hedging use cases, but the outcome of state-level policy disputes will shape how quickly event contracts enter mainstream derivatives desks.
