Kalshi is negotiating a funding round at a roughly $40 billion valuation, nearly doubling the $22 billion valuation assigned to the prediction market platform in May. The potential increase underscores the firm's rapid growth and operational scale within the financial markets sector, driven by heightened trading volume and regulatory advantages. However, Bernstein analysts warned Monday that Kalshi and Polymarket have become the most exposed names in prediction markets, sitting on valuable exchange tech with far less reach than the platforms now building around them. The two companies built real regulatory infrastructure early and still command serious private valuations, Kalshi near $22 billion and Polymarket around $15 billion, numbers that dwarf DraftKings' $12.5 billion market cap. Bernstein's point cuts the other way: valuation without distribution is exactly the profile of a takeover target.

Competitive Landscape and Distribution Gaps

Robinhood and Coinbase have tens of millions of existing users to route through their own exchanges. Kalshi and Polymarket don't have that built-in customer base, which is precisely why Bernstein lists both as plausible buyers or plausible targets depending on who moves first. Polymarket has already read the room, with its $112 million purchase of QCEX serving as a direct attempt to plug the same distribution gap before someone else exploits it through US re-entry. Additionally, Meta is reportedly building its own standalone prediction markets app, a sign of just how crowded this space is getting even before the existing players finish consolidating.

Revenue Retention and Strategic Shifts

Three separate companies reached the same conclusion independently this year: stop paying a third party to clear your bets. DraftKings spent eight months and $250 million acquiring Railbird to launch DKeX this week, finally moving off CME and Crypto.com rails. Robinhood built Rothera with Susquehanna and has already shifted its highest-volume World Cup contracts there instead of through Kalshi. Meanwhile, Coinbase bought The Clearing Company outright after launching event contracts, and now pulls in roughly $100 million annualized from the business in just two months. Bernstein's framing is blunt: "The revenue share that used to leave the building now stays inside it." Every company that controls its own exchange keeps fees that used to go to Kalshi.

Financial and Operational Milestones

The platform's valuation trajectory has been steep, rising from $5 billion in October 2025 to $11 billion in December, before the $1 billion Series F round led by Coatue in May. Investors in the May round included Sequoia Capital, Andreessen Horowitz, Morgan Stanley, IVP, Paradigm and Cathie Wood’s ARK Invest. The new valuation discussions come as Kalshi booked $21.1 billion in June trading volume, supercharged by the 2026 FIFA World Cup, while rival Polymarket and its US affiliate combined for about $9.7 billion.

Regulatory and Legal Challenges

A Flutter Entertainment and DraftKings combination would create the two richest customer databases in American betting under one roof, but Bernstein puts the odds below 5%. The FTC already blocked a DraftKings-FanDuel deal in 2017 over fears of a 90% market share in fantasy sports, and a Flutter-DraftKings tie-up would invite the same scrutiny. The bigger wildcard is regulatory. Minnesota passed what the CFTC calls the first outright ban on prediction markets, and Illinois now requires state licensing before offering sports contracts. Kalshi is fighting both in court, arguing CFTC jurisdiction preempts state gambling law, a case that could determine whether any of this consolidation talk survives contact with regulators. Kalshi's CFTC-regulated status has enabled institutional block trades and algorithmic flow that offshore competitors like Polymarket struggle to capture. CEO Tarek Mansour emphasized the company's "regulatory first" approach, citing strict KYC, market surveillance, and proactive trading bans on members of Congress. The Commodity Futures Trading Commission (CFTC), which had previously tried to halt Kalshi's event contracts on congressional elections, dropped its appeal against the company in May 2025.

Kentucky sued prediction markets Kalshi and Polymarket on Wednesday for operating illegal sportsbooks, naming Coinbase Global Inc. and Robinhood Markets Inc. as affiliates that helped route the bets. Attorney General Russell Coleman is invoking the state's Loss Recovery Act, which allows Kentucky to claw back triple the money residents lost on the platforms. The lawsuit alleges that nearly 89% of Kalshi's roughly $23 billion in 2025 contract volume came from sports wagering, challenging the platforms' classification as event contracts.

Coleman's office alleges Coinbase split fees with Kalshi on every bet placed through the crypto exchange. Robinhood and Webull were cited as affiliates that may offer few resources for problem gamblers, a requirement under Kentucky law. The state previously used the same 18th-century law to secure an $870 million judgment against PokerStars in 2015, a figure that grew past $1.3 billion with interest before Flutter Entertainment settled for $300 million.

The legal action centers on a regulatory standoff between state and federal authority. The platforms argue they answer to the Commodity Futures Trading Commission (CFTC) and are immune from state interference. Kentucky contends the products are sports betting disguised as financial instruments. The industry sued Kentucky on June 12 to block a new 14.25% tax on prediction-market trades, and a state law banning licensed sportsbooks from working with the platforms takes effect July 15.

Legal and Financial Implications

The lawsuit creates potential liabilities for the named public companies, Coinbase and Robinhood, as Kalshi and Polymarket are private entities. The state's ability to recover triple damages could result in significant financial penalties if the court rules the platforms operated as illegal gambling operations.

Kalshi spokesperson Jacki McGavick stated that the CFTC is the platform's regulator, not the states. Polymarket indicated the suit contradicts the federal framework. Traders on Polymarket currently assign only a 20% chance to a federal law banning sports prediction markets being enacted this year.
