Golden Age Prediction Markets: $1.45B Volume Surge in 2025

The year 2025 is shaping up to be the Golden Age of prediction markets, with trading volumes soaring to record-breaking levels across leading platforms like Kalshi and Polymarket. 

The surge reflects how these decentralized forecasting systems are maturing from niche crypto tools into mainstream financial instruments, blending speculative trading with real-world event outcomes.

A combination of institutional investment, technological innovation, and rivalry between major players has fueled unprecedented liquidity, signaling that prediction markets are entering a new phase of global adoption.

Prediction Markets Hit $1.45 Billion Weekly Volume

In late September 2025, prediction markets achieved a historic milestone — a seven-day trading volume of $1.45 billion, marking the highest levels since the 2024 U.S. presidential election cycle.

Key highlights include:

• Polymarket reported $1.43 billion in monthly trading volume, fueled by a surge in retail and institutional participation.
• Kalshi, a regulated U.S. exchange, outperformed on an annual scale with over $3 billion in total 2025 trading volume.
• Weekly transactions on Kalshi surpassed 3.4 million, underlining the platform’s growing engagement from traditional finance users.

This explosive growth underscores how forecast trading has evolved beyond political outcomes, now covering markets in macroeconomics, sports, crypto prices, and global events.

Institutional Backing and Tech Innovation Drive Growth

One of the most significant catalysts behind this boom is institutional adoption. In 2025, the Intercontinental Exchange (ICE) — parent company of the New York Stock Exchange (NYSE) — made headlines by investing $2 billion into Polymarket.

This move signaled Wall Street’s recognition of prediction markets as a legitimate alternative asset class, capable of reflecting real-world sentiment faster than traditional finance.

Other drivers include:

• Improved user interfaces that make prediction trading as seamless as crypto swaps.
• Smart contract automation for faster resolution and transparent payouts.
• Cross-chain liquidity aggregation, enabling users from Solana, Ethereum, and other networks to trade within a single market environment.
• Institutional-grade compliance frameworks, especially on Kalshi, which operates under CFTC oversight in the U.S.

These developments are making prediction markets more trustworthy, efficient, and accessible than ever before.
