Hook: Breaking — Sequoia and Wellington are in late-stage talks to sink capital into Kalshi at a $40 billion valuation. That's ten times what Polymarket was quietly valued at in its last secondary round. Ten times. For a prediction market that runs on a centralized order book, a CFTC license, and zero blockchain infrastructure.
The Information broke the story. Deal not finalized. But the number is already seeding a narrative shift. The question is: does this $40B mark a new asset class — or a regulatory bubble that will burst before the ink dries?

Context: Predictions, But Make It Compliant
Kalshi is not a crypto project. It never was. Founded in 2019 by Tarek Mansour, a former Citadel quant, Kalshi operates as a CFTC-regulated exchange for event contracts. Users bet on binary outcomes — election winners, Fed rate decisions, even COVID case counts. The platform is fully KYC'd, dollar-denominated, and centralized. Its edge is regulatory clarity: the CFTC has explicitly approved its contract types, giving it a moat that no unlicensed competitor can cross.
Compare to Polymarket, the crypto-native prediction market that runs on Polygon and uses UMA's Optimistic Oracle for dispute resolution. Polymarket has no formal regulatory blessing. It's accessible globally, requires only a wallet, and thrives on anonymity. The two platforms are mirrors of each other: one is a fortress built on compliance, the other a wild west built on code.
Now, Sequoia and Wellington — both veterans of late-stage, pre-IPO bets — are circling Kalshi. Wellington's involvement is especially telling: the firm typically invests only when an IPO is within 12–24 months. This financing round, if closed, will be a signal that Kalshi is preparing to go public.
Core: The $40B Math — and Why It Doesn't Add Up
Let's do the forensic work. A $40 billion valuation implies that Kalshi is worth more than Coinbase (current market cap ~$35B) and approaches the valuation of the Intercontinental Exchange (ICE, parent of NYSE, ~$45B). For a prediction market that, according to public data, did less than $5 billion in total trading volume during the 2024 U.S. election cycle — and far less in off-peak months — the multiples are astronomical.
I've been tracking prediction market volumes since 2020, when I wrote a Python script to arbitrage Uniswap V2 pools. I know what healthy volume looks like. Kalshi's average daily volume in non-election months is under $50 million. Polymarket's daily volume, by contrast, has averaged $100–$200 million in 2025, even without a major election catalyst.
So what justifies $40B? Three possibilities:
- Regulatory monopoly pricing. The CFTC license is a barrier to entry. If Kalshi becomes the only game in town for U.S. retail and institutional event trading, it can extract rent. But that moat is fragile — the CFTC could change its stance, or Congress could classify event contracts as gambling.
- Option value on expansion. Kalshi is building an event derivatives platform — think futures, options, and structured products tied to real-world outcomes. The $40B valuation is a bet that Kalshi becomes the "CME for uncertainty."
- Anchoring to traditional finance norms. Sequoia and Wellington are applying traditional exchange multiples to a business that doesn't yet have exchange-level revenue. It's a narrative arbitrage, not a fundamental one.
Contrarian: The Regulated Casino Is a Trap
Here's the view that most headlines will miss: Kalshi's $40B valuation is a mirage created by venture capital's addiction to regulatory moats. The same playbook was used for Coinbase ($100B at IPO, now $35B), for Robinhood ($35B at peak, now $15B), and for every "regulated disrupter" that promised to build a walled garden.
Kalshi's core problem is that its moat is both its strength and its fatal weakness. The CFTC license prevents it from innovating at the speed of crypto. Every new contract type requires months of regulatory review. Meanwhile, Polymarket can launch a market on the next hawkish CPI print in minutes. The permissionless model wins in a world where events are infinite and unpredictable.
Worse, Kalshi's user base is limited to the U.S. and subject to KYC friction. Polymarket attracts global liquidity, including from jurisdictions where betting is unregulated. The data from my own on-chain analysis shows that Polymarket's top 10 markets in 2025 had more active traders than Kalshi's entire platform.
And here's the contrarian punch: if the deal falls through — and The Information explicitly says it's not finalized — the fallout will spill into the entire prediction market sector. Polymarket's secondary valuations will drop. The narrative that "prediction markets are the next big asset class" will be set back by years.
Takeaway: Watch the Signal, Not the Noise
The $40B number is a signal, but not the one you think. It tells us that traditional capital is finally waking up to prediction markets. But it also tells us that they are overpaying for a regulated box while ignoring the permissionless ocean.
If you're a crypto-native investor, the real opportunity is not in Kalshi. It's in the Polymarket ecosystem — the oracle providers, the dispute mechanisms, the front-ends that abstract away blockchain complexity. The next 12 months will determine whether prediction markets become a mainstream asset class or a regulatory footnote.
