Kalshi closed a $1 billion funding round on May 7 at a $22 billion valuation, led by Coatue Management with Morgan Stanley, Sequoia, Andreessen Horowitz, Paradigm, IVP, and ARK Invest. Annualized trading volume reached $178 billion, up from $52 billion six months earlier, and Kalshi now accounts for more than 90% of U.S. prediction market activity.
The raise landed during a national legal fight. Arizona filed 20 criminal misdemeanor charges against Kalshi in March, accusing the company of running an unlicensed gambling operation. Nevada courts blocked the platform from offering sports and entertainment contracts under an injunction extended in April.
The CFTC and Justice Department responded by suing Arizona, Connecticut, and Illinois to assert that federal oversight of derivatives preempts state gambling law. A Third Circuit ruling on April 6 backed the CFTC in the New Jersey case, but the Ninth Circuit heard arguments on Nevada on April 16 and appeared to lean the other way. If confirmed in its written ruling, that disagreement could send the preemption question to the Supreme Court.
Why it matters
Kalshi now competes with futures exchanges and sportsbooks, giving traders one venue to hedge elections, weather, and Fed decisions.

Historical Context
2 moments from history that rhyme with this story — and how they unfolded.
1 of 2
October 2015 - 2018
Daily fantasy sports state battles (2015-2018)
DraftKings and FanDuel grew from niche fantasy sports operators into billion-dollar consumer brands by selling daily contests with cash prizes. New York Attorney General Eric Schneiderman declared the products illegal gambling in November 2015, and other states followed with cease-and-desist orders. The companies argued the contests were games of skill exempt from state gambling laws.
Then
DraftKings and FanDuel pulled out of several states and faced an estimated $50 million in legal costs. A planned merger collapsed in 2017 under Federal Trade Commission antitrust pressure.
Now
Both companies eventually negotiated state-by-state legalization frameworks for daily fantasy and pivoted into licensed sportsbooks after the 2018 Supreme Court PASPA decision. DraftKings went public in 2020 at a $3.3 billion valuation.
Why this matters now
Kalshi faces the same state-versus-federal jurisdiction question over sports event contracts that DraftKings and FanDuel faced over daily fantasy sports. The DFS pattern suggests state battles can be expensive and slow but do not necessarily stop the underlying business model.

Bitcoin spot ETF approval
After more than a decade of Securities and Exchange Commission rejections, the SEC approved 11 spot Bitcoin exchange-traded funds on January 10, 2024. BlackRock, Fidelity, and other large asset managers launched products that quickly attracted tens of billions in inflows, ending a regulatory standoff that began with the first Winklevoss filing in 2013.
Then
Spot Bitcoin ETFs took in roughly $30 billion in net inflows in their first year, the fastest-growing ETF category in history.
Now
Bitcoin moved from a fringe asset that institutions could not legally hold to a category line item in pension funds, endowments, and corporate treasuries. The approval pulled in spot Ether ETFs and reset how regulators evaluated novel asset classes.
Why this matters now
Kalshi's institutional volume growth follows the same arc: a financial product the largest investors could not touch becomes mainstream once regulatory and infrastructure barriers fall. The Bitcoin precedent suggests once the institutional dam breaks, capital flows compound quickly.
