Crypto Market Bets on Major Geopolitical Events

The intersection of cryptocurrency and geopolitical speculation has reached a record peak, as prediction markets transition from niche crypto-native bets to mainstream indicators of global conflict and macroeconomic shifts. Recent data indicates that these platforms are now being used to forecast high-stakes international events, including the probability of military conflict between the United States and Iran.

On the prediction platform Polymarket, traders have placed bets suggesting a 63% probability of a conflict between the U.S. And Iran. This trend reflects a broader shift in how these markets operate, with geopolitical and macroeconomic events now dominating trading volumes over traditional cryptocurrency-related topics.

Rapid Growth and Market Expansion

The scale of prediction market activity has expanded significantly throughout early 2026. According to a report from TRM Labs, monthly notional trading volume reached approximately $23.9 billion in March 2026. This represents a sharp increase from the $1.9 billion recorded during the same period in 2025.

The surge is not merely the result of larger bets from existing users but is driven by a rapidly expanding participant base. The number of monthly unique wallets tripled to approximately 840,000 by February 2026. This growth has been supported by several factors, including improved accessibility, evolving regulatory clarity, and the integration of live odds into mainstream media and Google Finance.

Transaction volume has seen a similar spike, with the total number of transactions crossing 191 million in March 2026, marking an increase of more than 2,800% compared to the same period in the previous year.

Shift Toward Geopolitical Indicators

While these platforms originated within the crypto community, the nature of the contracts being traded has evolved. Geopolitics, U.S. Politics, and macroeconomic decisions now account for the majority of trading activity. TRM Labs notes that these markets are increasingly serving as real-time indicators of geopolitical and macroeconomic events.

Analysis of on-chain trading patterns has identified specific clusters of coordinated activity that coincided with major global events, such as U.S. Airstrikes against Iran. These patterns have raised concerns regarding potential market manipulation.

Regulatory Response and Market Integrity

The rise of these markets as tools for geopolitical forecasting has drawn the attention of policymakers. In the United States, recent legislative proposals have called for explicit bans on insider trading within prediction markets to address the risks associated with participants who may have access to non-public information.

In response to these concerns and the emerging policy framework, major platforms have begun implementing new controls. On March 23, 2026, both Kalshi and Polymarket publicly outlined measures to curb insider trading, focusing on restrictions for participants with potential access to non-public information and the enhancement of market integrity controls.

Participant Profiles

The user base of these platforms is segmented by trading frequency. TRM Labs identifies three primary cohorts of participants:

• Mid-frequency traders, who execute between 11 and 1,000 trades, representing the most active cohort.
• High-frequency market makers, who execute more than 10,000 trades.
• New entrants, who contribute a smaller but significant share of total participation.

This diversification of the user base, combined with the shift toward global political events, positions prediction markets as a significant global financial market, though they remain subject to ongoing regulatory scrutiny regarding their influence and the integrity of their odds.
