When was the last time you saw a $1B+ funding round in Web3?
On October 7, 2025, Polymarket announced that Intercontinental Exchange (ICE), parent of the NYSE, would make a $2 billion strategic investment, valuing Polymarket at $9 billion post-money. It’s one of the largest raises for a Web3 project in recent years and pushes prediction markets squarely into the spotlight.
Momentum is building on both fronts—decentralized players like Hyperliquid are entering, while compliance-first late movers such as Kalshi are accelerating. The race is visibly heating up.
Behind it all is a bigger question: not just who will lead prediction markets, but how to turn real-world uncertainty into tradable financial products.
1. From Polymarket to Kalshi: growth on multiple fronts
Prediction markets have long been a core early blockchain use case—“OG” examples like Augur let users trade Yes/No outcomes on elections, weather, inflation, sports, IPOs, and more.
The concept only broke into the mainstream with Polymarket—helped materially by the 2024 U.S. presidential election. While traditional polls leaned one way, Polymarket offered more accurate, verifiable price signals—backed by real money.
As credibility grew, major media began citing Polymarket’s probabilities. Compliance remained a drag. In 2022, the CFTC fined Polymarket $1.4 million for operating an unregistered derivatives venue and barred it from serving U.S. users.
Over the past two years, Kalshi—founded before Polymarket—took a compliance-first path, becoming the first CFTC-regulated prediction-market platform. In October 2024, a federal court also cleared it to list the first regulated U.S. election markets, further solidifying its standing.

As of October 10, 2025, Polymarket leads on total volume—$1.3B versus Kalshi’s $410M—while trailing on market count (10.2k versus 43.5k) and open interest ($170M versus $240M).
Seeking a U.S. return, Polymarket acquired QCX LLC (CFTC-licensed) for $112 million in July and began self-certifying event contracts, including sports and elections.
This likely pairs with the new $2 billion round; on October 9, CEO Shayne Coplan also tweeted the POLY ticker—potentially a key variable in the two-horse race.
2. From prediction markets to the broader superset
Why would ICE place a $2 billion bet on Polymarket?
Step outside Web3 and view prediction markets through a broader finance lens.
First, ICE has long been active in crypto—across spot and futures products and via affiliated initiatives such as Bakkt.
Second, prediction markets are a type of trading venue. On Polymarket, many markets are effectively dated price outcomes for BTC, ETH, and other majors (e.g., end-of-October, year-end).
Conceptually, as you make the settlement timeline more granular—from “by year-end” to “in one minute”—you approach instantaneous wagers that mirror buy/sell actions. ICE likely values the ability to turn any uncertainty into a tradable instrument, extending the frontier beyond traditional futures and options.
A high-volume venue like Polymarket can serve as a distribution rail for ICE’s future structured products, institutional hedging tools, and information-pricing services—in short, a bet on derivatizing uncertainty at scale.
That’s why decentralized players like Hyperliquid are exploring a hybrid path—embedding prediction modules into high-performance derivatives platforms. The approaches have different strengths and may either complement or compete over time.
3. A new variable: Hyperliquid and other decentralized entrants
Consider Hyperliquid’s HIP-3: at the protocol layer it enables permissionless, developer-deployed perpetual markets. Previously only the core team could list; now any user staking 1,000,000 HYPE can deploy a market on-chain.
In short, HIP-3 enables permissionless creation and listing of derivatives for any asset—breaking the old Perp DEX constraint of only blue-chip crypto pairs( see Hyperliquid’s “Singularity Moment”: How It Kicked Open the Door for On-Chain Derivatives).
Beyond open listing, this lays the groundwork for a prediction-market module. In the future, users could trade markets such as:
- “Will the Fed cut rates at its next meeting?”
- “Will BTC break $70,000 this week?”
- “Will Arbitrum TVL surpass Base by month-end?”
Under this architecture, the prediction market becomes a module within a high-performance on-chain derivatives system, reusing order-book depth, clearing, and matching—yielding higher throughput and better capital efficiency.
By contrast, Polymarket skews toward event trading, while Hyperliquid skews toward price trading. Different starting points—same endgame: pricing the future in real time.
Closing Thoughts
With Hyperliquid’s entry and ICE’s $2 billion investment as bookends, prediction markets have moved beyond a niche betting tool into front-line instruments for institutions, analysts, and even central banks to gauge sentiment.
They’re no longer just speculators’ playgrounds—they’re rapidly evolving into high-efficiency, high-liquidity derivatives venues and an essential financial primitive in the DeFi stack.
