Kalshi And Polymarket Risk Getting Swallowed In Prediction Market Stack War

Prediction market leaders Kalshi and Polymarket could turn into acquisition targets after eight months of rivals racing to own both distribution and trading infrastructure.

Key Points:

Kalshi, Polymarket Face Takeover Pressure

The warning came from Wall Street broker Bernstein, in a Monday note led by analyst Ian Moore that framed the pair as plausible targets and plausible buyers at the same time. Over the past eight months, every major consumer-facing platform has moved to own both customer distribution and exchange technology under one roof.

The two leaders own the exchange piece, but they trail badly on consumer reach.

DraftKings moved its prediction trading onto an in-house exchange, DKeX, in late June after buying Railbird and pulling contracts off CME and Crypto.com rails. Robinhood launched Rothera at the end of May with help from Susquehanna, while Coinbase grabbed The Clearing Company soon after rolling out event contracts. Flutter, for its part, set up a dual structure that preserves access to more than one outside venue.

Robinhood, Coinbase Hold Strongest Hands

Bernstein reads that scramble as convergence, with prediction markets, sportsbooks and consumer finance folding into a single competitive arena. The shift makes deals that looked far-fetched a year ago suddenly credible, from sportsbooks buying exchanges to outright mergers between the largest betting operators.

The firms pairing wide audiences with owned, regulated rails now sit in front, the analysts said, and Robinhood and Coinbase fit that description most cleanly.

Each one now keeps the fees that used to leak out to third-party venues, a swing the note describes as a structural edge. Robinhood routed its busiest World Cup contracts through Rothera rather than Kalshi.

The raw figures show how fast the ground has moved beneath the two leaders. Robinhood has cleared more than 16 billion event contracts so far this year, Coinbase has reached roughly $100 million in annualized prediction revenue, and DraftKings reported consumer volume nearing $3.4 billion.

Regulation still clouds the outlook for everyone in the field. State gaming agencies call the sports contracts unlicensed betting, while the Commodity Futures Trading Commission claims exclusive federal authority over the products.

That fight could end up before the courts, a risk that shadows every valuation in the space.

The deal chatter follows a frantic fundraising stretch, with Kalshi chasing a $40 billion valuation that runs nearly triple the $15 billion Polymarket is said to target. World Cup trading has fueled the surge, lifting monthly volumes far above where they stood in spring.
