Two billion dollars in annualized revenue. That's the number Kalshi reportedly crossed before its bankers started circling. A Friday report from The Informant, cited by Cointelegraph, says the prediction market platform has opened early, informal conversations with investment banks about a public listing. Unnamed sources called the talks preliminary. A Kalshi spokesperson wouldn't comment.
So this is the soft, deniable stage of going public: nothing filed, nothing committed, a few dinners and some math on a whiteboard. Companies float these talks for a reason, though, and the reason here isn't hard to find. The business is printing money, and a window may be open.
The numbers behind the chatter
Kalshi's run over the past year has been steep. Back on May 7, Cointelegraph reported that a $1 billion Series F led by Coatue Management had pushed the company's valuation to $22 billion, double its prior mark. Now the $2 billion annualized revenue figure gives the IPO conversation something concrete to stand on. Revenue at that scale, in a category that barely existed at commercial size a few years ago, is the sort of thing that gets bankers to clear their afternoons.
What's powering it is no mystery. Sports betting contracts made up roughly 53% of Kalshi's weekly notional trading volume, per Dune data. More than half the engine, in other words, runs on people wagering on games.
And that's not a Kalshi quirk. Over at Polymarket, sports-related betting accounted for about 69% of weekly volume. The two biggest prediction venues in the US have both, intentionally or not, become places where the marquee product is the same product sportsbooks sell. Election markets and economic contracts get the press releases. The cash flow leans on whether a team covers the spread.
Which raises the obvious question hovering over any prospectus Kalshi might eventually write.
The lawsuits that could spoil the party
If you're underwriting a Kalshi IPO, you spend a lot of time on one page of the risk factors: the legal one.
Kentucky just became the latest state to take aim, suing five prediction markets including Kalshi and Polymarket. The complaint accuses the platforms of running "unlicensed and illegal sports betting" operations. Kentucky isn't alone. At least 17 other states have hauled prediction market operators into court over the same basic grievance.
The dispute comes down to jurisdiction, which sounds dry until you see how much money rides on the answer. State regulators say a contract on a sporting event is, functionally, a sports bet, and sports betting requires a state license. Kalshi and its peers counter that their event contracts are swaps, governed under federal commodities law, which would put them outside the reach of state gambling regimes entirely.
The US Commodity Futures Trading Commission has stepped into the middle, and not as a bystander. The CFTC's view is that event contracts qualify as swaps because they settle on binary outcomes. It backed that with a no-action letter on May 14 meant to loosen reporting requirements on event contracts. The agency has also gone on offense, suing at least five states (Wisconsin, New York, Arizona, Connecticut and Illinois) to lock down its claim of authority over the sector.
So you have a federal regulator and a clutch of state attorneys general pointing in opposite directions, with the prediction markets caught in between and, oddly, rooting for the federal side. It's an unusual posture for a crypto-adjacent firm: wanting more federal oversight, not less. But if the CFTC wins the framing, Kalshi gets one rulebook instead of fifty. Worth a great deal to a company eyeing public markets.
Here's the awkward part for any IPO timeline. The single biggest revenue category is the same one drawing the lawsuits. An underwriter can model around regulatory risk. It's harder to model around the possibility that your core product gets reclassified as illegal gambling in a third of the country. A favorable federal ruling clears the runway. An adverse one, or just a long stretch of unresolved litigation, leaves Kalshi trying to price a company whose largest line item carries an asterisk.
My read, and it's only a read: the early-talks framing is doing some work here. You don't commit to a listing date with the legal questions this live. You keep the bankers warm, watch the courts, and reserve the right to move fast if the CFTC's position firms up. That's a sensible way to play a genuinely uncertain hand.
What a public Kalshi would actually mean
Assume the litigation breaks Kalshi's way, or at least settles into something investors can price. A listing would make Kalshi the first pure-play prediction market to trade on a public exchange, and that matters beyond the company itself.
Public markets demand disclosure: quarterly revenue splits, contract-by-contract volume, the real margin on a sports event versus a CPI print. Right now the best public window into how these platforms make money is third-party dashboards like Dune. An S-1 would replace estimates with audited figures, and that transparency would reshape how everyone, regulators included, talks about the size and shape of this market.
It would also hand the rest of the field a benchmark. Polymarket, which has historically run a more crypto-native, offshore-flavored structure, would suddenly have a listed comparable to be measured against. Valuation multiples, growth rates, the cost of compliance: all of it becomes legible once one player files.
There's a timing irony worth sitting with. Kalshi spent years presenting itself as the buttoned-up, CFTC-regulated alternative, the prediction market your compliance officer could live with. That reputation is exactly what makes an IPO plausible. Yet the revenue that makes the IPO attractive comes substantially from sports contracts, the very products putting it on the wrong end of state lawsuits. The respectable framing and the cash machine are, at the moment, pulling in slightly different directions.
What to watch from here
None of this is settled, and the report itself is careful to say so. Talks are early. No bank has been formally mandated, at least not publicly. No timeline exists.
The variables to track are clear enough. First, the CFTC's litigation against the five states, because a win there would do more for Kalshi's listing prospects than any roadshow. Second, whether the count of suing states keeps climbing past the current 18 or so, which would deepen the risk-factor problem. Third, any sign that the informal bank talks harden into something concrete: a lead underwriter, a confidential filing, a target range.
Until then, the $22 billion Series F valuation sits as the working number, set by private investors with conviction and patience. An IPO would test that number against a public market that prices regulatory uncertainty for a living. Whether Kalshi wants to take that test now, or wait for the courts to clear, is the decision worth watching.
