Prediction Markets Hit $20B as Politics Drive Surge
Prediction markets are booming, with geopolitical and political bets now driving most activity as institutional money and regulatory scrutiny intensify.
The global prediction market sector has entered a new phase of rapid expansion, surpassing $20 billion in monthly trading volume for the first time as users increasingly wager on geopolitical and political outcomes rather than crypto-native events.
According to a March 27 report by blockchain analytics firm TRM Labs, the surge reflects a structural shift in how users engage with platforms like Polymarket, where macro-driven narratives now dominate trading activity.
Explosive Growth Driven by Macro Events
Prediction markets have seen extraordinary growth in just six months. Monthly transaction volume climbed from $1.2 billion in early 2025 to over $20 billion by February 2026, while the number of unique wallets more than tripled to 840,000.
This growth has been fueled largely by:
- Geopolitical conflicts and global tensions
- Macroeconomic developments, including central bank policy
- U.S. political events and election cycles
These categories now represent the majority of trading activity, overtaking crypto-related markets that once defined the sector.
A Shift Away From Crypto-Centric Betting
While prediction markets initially gained traction among crypto users betting on token prices, that trend has diminished significantly.
The report highlights that crypto price markets now represent only a small share of activity across all user segments. Instead, user attention has shifted toward real-world events with broader societal impact.
Meanwhile, sports and entertainment markets have found a niche among mid-tier traders and experienced participants, but they do not dominate overall volume.
Inside Polymarket’s Trading Structure
TRM Labs identified several defining characteristics of Polymarket’s evolving ecosystem, pointing to a fragmented but highly active market structure.
Geopolitics Takes Center Stage
At the top end of trading activity, geopolitical markets dominate, but liquidity is often spread across multiple overlapping contracts. These include bets on:
- Leadership outcomes
- Military conflict scenarios
- Policy decisions
Rather than consolidating into single high-volume narratives, trading is dispersed across numerous related questions.
U.S. Politics Remains a Core Pillar
Contracts tied to U.S. political developments consistently rank among the platform’s most active markets, reinforcing their role as a secondary but stable driver of volume.
A “Super App” for Event Trading
Unlike traditional financial platforms, Polymarket does not distinguish between different types of contracts based on seriousness or category. Instead, it offers a unified experience where users can trade outcomes across:
- Politics
- Culture
- Sports
- Crypto
This “super app” approach allows for seamless participation across diverse event categories within a single interface.
What Winning Traders Are Doing
The report also sheds light on the strategies used by top-performing traders on the platform.
Among the 10 most profitable wallets in early 2026, three dominant approaches emerged:
- Macro conviction trades based on strong directional views
- Algorithmic market-making strategies
- Event-driven opportunism tied to specific outcomes
The top-performing wallet generated an impressive $6.2 million in profits, trading across a wide range of markets including Federal Reserve decisions, the World Cup, and the 2028 U.S. election.
Notably, six of the top ten wallets were active daily over an 80-day period from Jan. 1 to March 22, underscoring the importance of consistent engagement and strategy execution.
Concerns Over Insider-Like Activity
Despite the sector’s growth, TRM Labs flagged several behaviors that resemble market manipulation patterns seen in traditional finance.
These include:
- Coordinated wallets entering positions ahead of major news events
- One-time, high-conviction bets followed by immediate exit
- Thin markets dominated by a single participant influencing pricing
One striking case involved four wallets that turned approximately $40,000 into $872,000 by betting on U.S. military action against Iran in early 2026.
TRM Labs noted that these wallets:
- Funded positions through the same bridge within a narrow timeframe
- Entered markets priced between $0.10 and $0.80 per share
- Redeemed at $1 upon resolution
- Withdrew funds and did not return to the platform
The shared infrastructure and coordinated timing suggest potential information asymmetry or strategic collusion, raising concerns about fairness and transparency.
Institutional Capital Enters the Arena
The report coincides with a major institutional development involving Intercontinental Exchange, the parent company of the New York Stock Exchange.
On March 27, ICE confirmed it had completed a $600 million direct cash investment in Polymarket, signaling growing confidence in prediction markets as a new growth vertical.
The company also revealed plans to purchase up to $40 million in additional securities from existing shareholders.
This move builds on a previously announced commitment in October 2025, when ICE outlined plans to invest up to $2 billion in the platform—one of the largest institutional bets on the sector to date.
While the valuation of the latest investment was not disclosed, the deal underscores ICE’s intent to expand its footprint in alternative trading markets.
Rising Regulatory Pressure in the U.S.
At the same time, prediction markets are facing increasing regulatory scrutiny across the United States.
At least 11 states have taken action against platforms such as Polymarket and Kalshi, reflecting growing concerns over their legal classification and operational models.
Key developments include:
- Nevada issuing a temporary ban on Kalshi
- Arizona filing criminal charges, alleging illegal gambling operations
- Multiple states issuing cease-and-desist orders or considering new legislation
In response, platforms have begun implementing stricter safeguards.
Both Polymarket and Kalshi announced new measures on March 23 aimed at reducing insider-style trading risks, including:
- Restrictions on users with access to non-public information
- Enhanced market integrity controls
Polymarket has also updated its rules to explicitly prohibit trading based on confidential information, as critics warn that prediction markets may be particularly vulnerable to misuse in areas like politics, sports, and geopolitics.
A Market at a Crossroads
Prediction markets are rapidly evolving from niche crypto experiments into high-volume platforms influenced by global events and institutional capital. The shift toward geopolitics and macroeconomic outcomes signals broader mainstream relevance—but also introduces new complexities.
As billions of dollars flow into these markets, questions around fairness, transparency, and regulation are becoming harder to ignore. With major players like ICE stepping in and regulators stepping up, the next phase of growth may depend less on expansion—and more on how the industry addresses its emerging risks.
