Kalshi and Polymarket Post Record Volume as Prediction Markets Hit Nearly $10 Billion in November

Prediction markets are entering their strongest era to date. In November 2025, Kalshi and Polymarket collectively recorded nearly 10 billion dollars in trading volume, marking the most active month in the history of the sector. This surge shows that prediction markets are no longer niche experiments. They are becoming influential financial instruments used by millions of traders, analysts and institutions.

The industry’s rapid expansion reflects growing interest in real world event trading, increased liquidity and a shift in how investors view information markets.

 

How Kalshi and Polymarket Reached New Heights

Institutional Investment and Regulatory Clarity

Kalshi has positioned itself as the regulated prediction exchange in the United States. With a green light from federal derivatives regulators, the platform attracted significant institutional investment. Its most recent funding round valued the company at approximately 11 billion dollars.

Polymarket, on the other hand, grew from the crypto native community. Its decentralized architecture and global accessibility attracted users drawn to event based markets that operate without borders. As Polymarket expanded, its volume accelerated sharply, particularly in 2024 and 2025.

Together, the two platforms now represent the core of the prediction market ecosystem. One operates with traditional oversight, and the other leverages blockchain transparency. Both models have succeeded by meeting rising demand for trading around news, sports, politics and global uncertainty.

Surge in Demand From Sports, Politics and Macroeconomics

The November boom appears to have been driven by significant events across sports and entertainment, along with heightened activity in political and macroeconomic markets. Major sporting events, international political developments and volatility in global markets created a perfect environment for event driven speculation.

Polymarket in particular saw sharp month over month growth, with more than 3 billion dollars traded in October followed by an even stronger November contribution. Kalshi also reported record numbers across political, sports and economic categories.

 

What This Means for the Future of Prediction Markets

Prediction Markets Are Becoming a Serious Asset Class

A combined 10 billion dollars in monthly trading volume places prediction markets in the realm of legitimate financial instruments. This surge demonstrates that traders are increasingly comfortable speculating on real world outcomes using structured markets rather than informal sentiment or traditional betting platforms.

Liquidity and Market Depth Are Strengthening

As more capital enters the ecosystem, liquidity improves and spreads tighten. Higher liquidity reduces volatility and improves price accuracy, allowing events to reflect true market expectations. This makes prediction markets more reliable indicators of sentiment around elections, economic reports, policy shifts and high profile entertainment events.

Traditional Finance Meets Crypto Native Innovation

Kalshi and Polymarket represent two very different models. Kalshi is regulated, compliant and geared toward traditional market participants. Polymarket is decentralized, global and capable of listing a wide variety of markets. The success of both platforms shows that prediction markets can appeal to different audiences and regulatory frameworks while still growing in parallel.

New Hedging and Speculation Tools

Prediction markets enable traders to hedge against real world uncertainty. Instead of relying solely on equities, commodities or forex markets, users can now hedge or speculate directly on election outcomes, interest rate decisions, policy changes or cultural events. This is a fundamental expansion of what financial markets can price.

 

Challenges That Still Remain

Prediction markets face headwinds even as they achieve record volume.

• Regulatory uncertainty. Some jurisdictions classify certain event markets as gambling, while others treat them as derivatives.

• Concentration of liquidity. Large events dominate attention, leaving smaller markets with limited participation.

• Volatility around major events. Binary markets can swing sharply as news breaks, creating risk for traders and market makers.

• Infrastructure demands. Platforms must scale securely to handle institutional interest and larger volumes.

How Kalshi, Polymarket and future competitors handle these challenges will help determine whether prediction markets can sustain long term growth.

 

Final Thoughts

The combined 10 billion dollar surge in November volume from Kalshi and Polymarket signals a major shift in the financial landscape. Prediction markets are becoming mainstream. They are attracting serious capital, gaining institutional legitimacy and proving that people want tools that let them trade on real world information.

Whether it is politics, macroeconomics, sports or cultural events, prediction markets offer a new expression of financial participation. If growth continues, they may soon become a standard part of global finance, sitting alongside equities, futures, options and digital assets.

 

This moment marks the transition from niche concept to powerful market infrastructure. The prediction market revolution is now fully underway.
