Polymarket is reportedly raising at $12B to $15B, and Kalshi just closed at $11B.¹ ² Investors behind these companies include some of the largest late stage venture firms in the world, such as A16z and Sequoia. This signals how aggressively capital is now betting that prediction markets will become core financial infrastructure or a new economy wide information layer.
Does the landscape today justify those valuations and expectations?
Revenue Reality Check
Kalshi generated about $24M in verified revenue in 2024 on roughly $2B of annual volume. The company has since experienced rapid growth, with realized 2025 revenue estimated near $300M based on cumulative disclosed volumes and its historical 1% take rate.
A typical 10X revenue multiple would impute a valuation of about $3B. A generous 20X multiple implies $6B. The $11B valuation means investors were willing to pay an astonishingly optimistic 37X.
Polymarket meanwhile hasn’t started charging meaningful trading fees. Even with some yield and referral income, the platform hasn’t demonstrated recurring revenue, which makes a valuation of even $2B to $3B difficult to justify, let alone the $12B to $15B range sought.
Decacorn Benchmarks
Crypto exchanges are the closest apples to apples comparison for prediction platforms because they sit in essentially the same vertical. They enable consumer markets to access new and emerging financial products and require substantial novel infrastructure to do so at scale.
Long time Silicon Valley darling Coinbase generated about $1.9B in Q3 2025, serves on the order of 120M users, and currently trades at a valuation of around $75B.³
Kraken generated $648M in Q3 2025, serves roughly 15M users, and spent fourteen years building global licensing, custody, and institutional grade infrastructure to reach a $20B valuation.⁴
DraftKings, currently valued around $18B, offers a different but highly relevant comparison because it also monetizes outcome based trading. It generates more than $4B in annual revenue and serves tens of millions of verified users under one of the most complex regulatory regimes in the United States.⁵
Polymarket and Kalshi come nowhere close to the revenue, users, infrastructure depth, or regulatory breadth that normally supports valuations north of $10B in these kinds of verticals.
Footprint And Reach
Polymarket has seen monthly peaks near 500k active traders, and Kalshi has reached more than $5B in monthly volume on its markets.⁶ These figures demonstrate significant usage but still fall short of proving durable revenue or defensibility.
Jurisdictionally both remain narrow. Polymarket is only now preparing to re-enter the United States after years of operating primarily offshore. Kalshi is still limited to United States customers and has only begun the early stages of exploring international access.
Neither platform has anything close to the multiregion licensing footprint that established exchanges like Coinbase or Kraken maintain across dozens of major markets, and this limited geographic reach remains a significant structural constraint.
Excellent Execution, Still No Moat
Both teams deserve enormous credit for their execution. They’ve moved impressively fast in a new and regulatorily challenging category and secured a real first mover advantage in brand and liquidity. But that’s not a moat.
Once rules stabilize, any exchange, broker, bank, or decentralized protocol will be able to enter the prediction market space, potentially with more capital, talent, broader distribution, and deeper infrastructure.
We’ve seen that pattern before. In the early social media era, MySpace and Friendster dominated the narrative, but once the space matured, challengers like Meta, Google, and Twitter overtook them.
A similar dynamic is possible here, especially given the shifting regulatory picture. The House passed the CLARITY Act in July 2025, and the bill is now before the Senate for further work.⁷ Nothing about Polymarket’s or Kalshi’s current position demonstrates meaningful lock in or real barriers to entry once fair rules are settled.
Markets can be brutal when valuations depend too heavily on expectations instead of fundamentals. After the FTX collapse, Coinbase lost over 70% of its market value and Kraken private market marks dropped more than 90%.
The most chilling cautionary tale was OpenSea. Once the most hyped NFT platform and backed by A16z at a $13.3B valuation, it saw secondary valuations collapse by over 95% and never recover.⁸ This isn’t a prediction that Kalshi or Polymarket will follow the same path. The lesson is simply that short and medium term downside can be severe when durability remains unproven.
This even happened to Amazon, which fell 95% during the dot com crash. Of course Amazon eventually became Amazon. The question is whether Kalshi or Polymarket possess the fundamentals to survive similar pressure.
Exit Strategy
Kalshi and Polymarket’s combined $25B valuation implies multiples that public markets are unlikely to pay, despite their impressive growth. Both platforms would require significantly higher revenue, broader geographic coverage, and far more durable unit economics before public markets would support valuations in this range.
Could strategic buyers justify an acquisition?
Alternative asset exchanges like Coinbase or Kraken might find prediction markets to be a natural strategic fit. Integrating either platform would likely be operationally straightforward. But it’s difficult to imagine them justifying a price tag anywhere near $10B for businesses whose revenue models remain unproven.
Considering the reverse scenario as a hypothetical is instructive for illustrating why prediction may function better as an add-on than a standalone business. It’s absurd to imagine Polymarket or Kalshi acquiring a full stack digital asset exchange. The financial and operational asymmetry is far too large.
Additionally, Coinbase or Kraken could choose to stand up their own in-house prediction layer for a tiny fraction of the cost, perhaps as extensions of their layer 2 chains Base or Ink, which could also carry the competitive advantage of being more decentralized. Coinbase has already signaled explicit interest, listing prediction markets among the categories it aims to build around in 2026.⁹
A large TradFi buyer is more plausible, but only under specific circumstances and an attractive valuation. Prediction markets would likely need to become systemically important and more materially monetizable before such a move would make sense.
Outlook Hazy, Try Again
Prediction markets may indeed be a decade defining idea. They offer the first credible mechanism for real time pricing of real world uncertainty, and the long term upside could be enormous. I’m bullish on the category and even optimistic about Kalshi and Polymarket, despite my pessimism regarding their stock price.
I’d happily own these names at $2B or $3B today and ride or die with them as they build reach, monetization, liquidity, and real defensibility. But paying $10B for them now is effectively buying the perfect version of the bull case with no margin for error. And as history shows, in the short and medium term that can easily turn into a move with far more downside than upside.
