Kalshi is in talks to raise fresh capital at a valuation of $65 billion, roughly 62.5% above the $40 billion valuation it locked in only weeks earlier. The company, a US-regulated exchange where people trade contracts on the outcome of real-world events, closed a $1 billion round at $40 billion on October 29, co-led by venture firm Sequoia Capital and asset manager Wellington Management. That round had been described as Kalshi's last private raise before a planned share market listing.
The new talks are preliminary, and no round has closed. A Kalshi spokesperson declined to comment. But the speed of the step-up, a higher valuation floated within three weeks of a billion-dollar round that was supposed to be the final one, says as much about the company's trajectory as any single figure.
A 62.5% step-up in a matter of weeks
Kalshi's paper value has climbed steeply through 2026. It was valued at about $22 billion in May, in a $1 billion round led by investment firm Coatue in which Sequoia also took part. By the end of October that had risen to $40 billion, and the $65 billion now under discussion would mark a further 62.5% jump in less than a month. A year earlier the company was worth a small fraction of that.
Step-ups of this size inside a single quarter are rare even in fast-growing private technology companies, and they usually track a specific, measurable surge in the underlying business rather than market sentiment alone.
The numbers behind the jump
In Kalshi's case, the surge is in volume. The notional value of contracts traded on the platform each month roughly doubled from about $40 billion in August to near $100 billion in October. That pace has pushed the company to an annualized revenue run-rate reported above $5 billion, at gross margins of around 90%, the kind of margin profile usually associated with software rather than a marketplace.
The growth is not only sports. Kalshi's non-sports revenue run-rate has topped $1 billion on its own, a sign that contracts on economics, politics, culture and other events are scaling alongside the sports markets that drove much of the early traffic.
"A company of our financial profile with the rate of growth that we're seeing, that sort of conversation has to happen," chief executive Tarek Mansour said when the October round closed, referring to further fundraising. Mansour co-founded Kalshi and has run it from a niche regulated venue into the sector's largest player.
What "compute futures" would add
Part of the new money, as the talks have been framed, would fund a push into "compute futures": contracts whose value tracks the price of computing power, the raw capacity that trains and runs artificial-intelligence systems. The idea is to let firms and traders lock in or take a position on the cost of compute the way they already do with oil, wheat or interest rates.
That fits a product roadmap Kalshi set out in October. "We'll accelerate our prediction market growth, grow institutional adoption, launch new products like indices, single-share perpetual futures, and compute markets," the company said at the time. The compute-futures framing should be read as one stated ambition among several, not the sole purpose of the raise; the core driver remains the trading momentum in Kalshi's existing markets.
The IPO question
The awkward part is timing. When the $40 billion round closed, it was positioned as the last capital Kalshi would take as a private company, the round that cleans up the cap table before an initial public offering. A larger private round three weeks later complicates that story, either delaying the listing or raising the bar the eventual IPO has to clear.
Whether Kalshi or any of its peers reaches the public market inside this window is itself something traders are pricing.

Kalshi, Polymarket and the race for the sector
The raise lands as Kalshi consolidates a lead over Polymarket, the crypto-based prediction market that for years was the category's best-known name and which Kalshi has recently overtaken. Kalshi's edge is partly regulatory: it operates under oversight from the Commodity Futures Trading Commission, the US derivatives regulator, which lets it serve American customers directly in dollars rather than through crypto rails.
A fresh step-up valuation, on top of a rival losing ground, is the clearest signal yet that large institutional investors now see event contracts as a durable asset class rather than an election-year curiosity. The investors chasing Kalshi are taking a position on the category continuing to compound, which is a view, not a certainty.
What it changes for traders
For someone trading on Kalshi today, a richer, better-capitalised exchange generally means deeper liquidity, more markets and the balance sheet to launch the indices, perpetual futures and compute contracts the company has promised. None of that is guaranteed by a valuation headline, and a higher paper value does not change the price of any contract already open.
What it does change is the backdrop: the venue is being valued as critical financial infrastructure, and the capital now being discussed is meant to build the next set of products on top of the event contracts that got it here.
The $40 billion round in October was supposed to be the last money Kalshi raised in private. Three weeks later a bigger number is on the table, and the share-market debut it was meant to set up has quietly slid further out. The figure worth watching is not $65 billion, which is still only a conversation, but whether Kalshi closes it at all, from a company that keeps outrunning its own last word on when it will stop raising.
