Prediction Markets Hit $20B Monthly Volume as Geopolitics Overtakes Crypto Bets

Record-Breaking $20 Billion Monthly Volume

Prediction platforms have reached unprecedented activity levels, with monthly trading volume surging to $20 billion since the start of 2026, according to TRM Labs analysts. The number of unique wallets tripled over the same period, reaching 840,000.

The most significant shift has been thematic: geopolitical events, macroeconomic indicators, and U.S. political developments have displaced cryptocurrency-focused contracts that previously dominated prediction markets. This transformation coincided with a broader downturn in the digital asset sector.

Why This Matters

Prediction markets are evolving from a niche crypto tool into full-fledged infrastructure for hedging geopolitical and macroeconomic risk. A $20 billion monthly turnover puts them in the same league as major derivatives venues. The influx of institutional capital — ICE investing in Polymarket, Kalshi raising $1 billion — signals that traditional finance is taking the sector seriously. The shift away from crypto-native bets toward real-world events marks a maturation point for the entire category.

Geopolitics Takes Center Stage on Polymarket

On Polymarket, trading activity has pivoted toward tariff-related contracts (116 active markets), Ukraine ceasefire scenarios, and China-Taiwan tensions. A contract on a potential U.S. strike against Iran attracted $73 million — a record for geopolitical markets on the platform.

On February 28, Polymarket set a daily volume record of $425 million, surpassing the peak from the 2024 U.S. presidential election. The record was driven by the resolution of Iran-related markets. Betting volume on a contract about Khamenei's departure skyrocketed from $23,000 to $29.6 million in a single day — a 1,275x increase and the largest daily spike in the platform's history.

Market Structure: Four Defining Features

TRM Labs identified four structural characteristics of Polymarket's current landscape:

• Geopolitics dominates but is fragmented. Volume is spread across overlapping topics: leadership outcomes (Khamenei, Xi, Netanyahu), conflict scenarios (Iran, Ukraine, Venezuela), and U.S. political events including government shutdowns.
• U.S. politics remains the second-largest pillar. Contracts tied to domestic political events continue to generate substantial volume.
• No distinction between "serious" and "entertainment." War, elections, and macroeconomic contracts trade alongside pop culture and entertainment bets. The platform functions as a "super-app" where users trade diverse instruments in one interface.
• Crypto occupies a small share. International relations and macroeconomic markets lead across all tiers.

Top Traders: Strategies and Profitability

TRM Labs analyzed the ten most profitable wallets on Polymarket in early 2026 and identified three behavioral models:

• Macro conviction — several addresses focused on Federal Reserve decisions, earning a combined $3.26 million.
• Algorithmic market-making — one user earned $3.35 million through over a million small trades on Oscar-related markets.
• Event-driven opportunism — a trader created a wallet, capitalized on Ethereum price volatility, earned $709,000, and exited.

The top-performing address earned $6.2 million trading across Fed meeting markets, the FIFA World Cup, and the 2028 U.S. presidential election. Six of the ten wallets traded daily throughout an 80-day period from January 1 to March 22.

Billions Flow Into the Sector

On March 27, Intercontinental Exchange (ICE) announced a $600 million investment in Polymarket. The amount is part of a previously agreed funding package totaling $2 billion. ICE also disclosed the option to purchase up to $40 million in Polymarket securities from existing holders to increase its stake. Specific terms have not yet been disclosed.

Rival platform Kalshi raised over $1 billion in a new funding round, pushing its valuation to $22 billion. The round was led by Coatue Management.
