Key takeaways
– Kalshi’s valuation went from $11 billion in December 2025 to $22 billion in March 2026, and it is reportedly now in talks for a $40 billion round that could close this quarter.
– Polymarket was valued near $8 billion when Intercontinental Exchange committed $2 billion to it last October. It is now fielding a round that could price it above $20 billion.
– Kalshi has told investors it is exploring an IPO for late 2026 or early 2027, complicated by state lawsuits alleging it runs an illegal gambling operation.
– Bernstein analysts think the bigger story is M&A: DraftKings, Robinhood and Coinbase have all bought or built their own exchange infrastructure in the past year, which makes Kalshi and Polymarket plausible takeover targets as much as acquirers.

None of that is normal venture math. Venture math does not usually list the parent company of the NYSE as a line item. Infrastructure investors are pricing Kalshi and Polymarket the way they would price an exchange, not a startup, and exchanges tend to end up bought, folded into a regulated duopoly, or public. Watching which of those three arrives first is a source of much speculation and interest from the general investing community.
Is Either One Actually Going Public?
Kalshi is the one making noise. It has reportedly told investors it is exploring an IPO as early as late 2026 or early 2027, riding that $22 billion round. The complication is that several state attorneys general are currently suing Kalshi over whether its sports-related contracts amount to unlicensed gambling, a fight that needs to resolve, or at least stabilize, before an S-1 makes sense.
Polymarket has not put a date on anything. But a stock exchange operator and two of the largest quant shops in the world are not usually along for a ride that ends in a quiet sale to a strategic buyer. Neither company has filed. Both are behaving like they are clearing the runway.
The Trade Underneath the Trade Is M&A
Bernstein published a note in June arguing the more durable story is consolidation, not the IPO race. According to them, every consumer platform that actually matters in this category has spent the past year merging the front end, the app people trade on, with the back end, the CFTC-licensed exchange that clears the trade.
Two Industries Already Ran This Exact Play
Daily fantasy sports went through something close to this a decade ago. DraftKings and FanDuel controlled roughly 90% of that market and tried to just merge outright in 2016. The FTC and several state attorneys general sued to block it on antitrust grounds, and the deal died in 2017.
The consolidation happened anyway. It just took a slower, quieter route. Flutter bought pieces of FanDuel over several years and did not finish the job until this past July, paying Boyd Gaming $1.76 billion for the last 5% stake in a deal that valued FanDuel alone at $31 billion. Nobody blocked that one, because it never looked like the headline merger regulators were watching for.
That is the more realistic template for prediction markets than a Kalshi-Polymarket megamerger regulators would likely never clear. Watch for the DraftKings-and-Railbird-shaped deals, not the DraftKings-and-FanDuel-shaped ones.
