Forecasting Market "Big Year": What are Shayne Coplan and others competing for

In 2025, the prediction market suddenly became the hottest track.

The performance of the two leading platforms, Polymarket and Kalshi, best illustrates the point. Kalshi completed two funding rounds in just two months—on October 3, with a $3 billion valuation and a $5 billion valuation, and again in November raising $1 billion, with its valuation soaring to $11 billion, driven by Sequoia Capital and CapitalG; Polymarket is even more aggressive, with the New York Stock Exchange parent company ICE directly investing $2 billion, bringing its valuation to about $9 billion. The consensus reflected behind these funding figures is very clear: capital has recognized the true potential of this industry.

From ballots to events: the expanding business landscape of prediction markets

During the 2024 US presidential election, these platforms tasted success. A major French bettor on Polymarket, tracked by Chainalysis, made $78.7 million by betting on Trump’s victory. This is not just a personal wealth story but more importantly proves how crazy the trading volume in prediction markets can get.

Entering 2025, the commercial reach of these two major platforms extends into more fields. Kalshi has formed content partnerships with CNBC and CNN; Polymarket has teamed up with Yahoo Finance and UFC; and both platforms have signed multi-year licensing agreements with the NFL. From politics to sports events, prediction markets are transforming from a niche concept into a scalable infrastructure.

Why Shayne Coplan and others are interested in “collective intelligence”

Why is capital suddenly so crazy? Leo Chan, CEO of Sportstensor, has a very representative view—the true value of prediction markets lies not in the platforms’ short-term revenue but in the collective intelligence they generate and the globally distributed prediction data. This data is highly valuable to financial institutions and ordinary decision-makers.

In other words, what Shayne Coplan, CEO of Polymarket, and others are doing is not just creating a trading platform but building a decentralized “collective prediction system.” This system can aggregate information and judgments from global participants in a market-based way, ultimately forming the most accurate predictions of future events.

The watershed has arrived

As the 2026 US midterm elections approach, prediction markets are expected to once again become a hot topic, perhaps even more wildly than the 2024 presidential election. But the market is also asking a deeper question: can these platforms truly evolve from “traffic and topic-driven” to scalable prediction infrastructure?

Short-term funding frenzy is easy, but long-term value creation is difficult. 2026 will be the test—whether prediction markets can prove their unique role in information discovery, risk pricing, and decision support will determine whether this track moves from a craze to maturity or returns to ordinary from its peak.
