Kalshi and Polymarket Hit Record Trading Volumes in October

• Kalshi hit a new platform record with $4.4 billion in monthly trading volume for October, cementing its lead in the regulated prediction markets space.
• Polymarket saw a massive rebound, with monthly active traders surging 93.7% to an all time high of 477,850, driven by POLY token airdrop rumors.
• Polymarket’s trading volume also hit a record $3.02 billion, breaking a long period of lower activity and highlighting a surge in retail interest.
• The catalysts for the Polymarket surge are attributed to platform innovation and strong speculation around a native POLY token airdrop and a potential US market re entry.
• The parallel success of the regulated Kalshi and decentralised Polymarket platforms indicates the prediction market sector is rapidly expanding on two distinct fronts.

Kalshi’s Regulated Framework Drives Record Volume

The regulated prediction markets sector in the United States saw its strongest performance to date in October, led by Kalshi. The CFTC regulated exchange logged an all time high of approximately $4.4 billion in monthly trading volume. This record performance is a clear signal that Kalshi’s compliance first model is successfully attracting mainstream and institutional attention, proving the viability of event contracts as a new tradable asset class for a US audience.

Polymarket Rebounds with All Time High Active Traders

While Kalshi dominated in total volume, October marked a “remarkable comeback” for the decentralised prediction market platform, Polymarket. After seeing its monthly active user base dwindle to a low of 227,420 in August, Polymarket saw explosive growth in October. The number of monthly active traders skyrocketed to 477,850, a 93.7% increase from September and a new all time high for the platform.

This surge in user engagement translated directly into trading volume. Polymarket recorded $3.02 billion in monthly volume, smashing its previous records. The platform also saw a massive spike in new market creation, with 38,270 new markets launched in October, nearly triple the number from August, indicating a highly engaged retail user base.

POLY Token Airdrop Rumors Fuel Polymarket Surge

Analysts are attributing Polymarket’s dramatic October turnaround to a combination of platform innovation and powerful incentives. The primary catalyst appears to be the announcement of a planned native POLY token and the strong speculation surrounding a future POLY token airdrop. Historically in the crypto space, the promise of a lucrative airdrop drives a massive influx of new users and speculative activity as traders position themselves to meet eligibility criteria. This, combined with rumors of the platform’s re entry into the US market and a potential $15 billion valuation, created a perfect storm of market hype and user acquisition.

A Prediction Market Battleground: Regulation vs. Decentralisation

October’s results highlight the two diverging paths for the prediction market sector. Kalshi’s success, built on its regulated prediction markets framework, is pulling the industry closer to mainstream finance and institutional capital. In contrast, Polymarket’s revival, powered by blockchain technology and crypto native incentives like the POLY token airdrop, showcases the power of a decentralised, community driven approach. With both platforms now reporting monthly turnover in the billions and user growth at all time highs, the prediction market sector looks poised for a new phase of major expansion.

Expert Analysis: A Dual-Track Breakout for Prediction Markets

October’s record breaking numbers for both Kalshi and Polymarket are not just a blip; they signal a dual track breakout for the prediction market industry. Kalshi’s $4.4 billion trading volume is a resounding validation of the regulated prediction markets model. It proves that a fully compliant, CFTC regulated platform can attract significant, mainstream capital, successfully legitimising event contracts as a new financial asset class. This is the pathway that brings institutional investors into the ecosystem and solidifies prediction markets as a permanent fixture in the US market landscape, moving them out of a legal grey area and into the realm of traditional finance.

In parallel, Polymarket’s explosive resurgence, driven by a 93.7% leap in monthly active traders, demonstrates the sheer power of the crypto native, decentralised model. The POLY token airdrop rumors acted as a powerful user acquisition engine, a classic Web3 growth strategy that a regulated entity like Kalshi simply cannot deploy. Polymarket is successfully tapping into a global, crypto savvy user base that is highly motivated by speculative incentives and platform rewards. This creates a deeply engaged community that is less concerned with regulatory nuances and more focused on product innovation and profit potential, as evidenced by the 38,000+ new markets created in a single month.

This “battleground” is less of a zero sum game and more of a rapid expansion of the entire sector along two distinct philosophies. We are seeing the prediction market industry bifurcate: Kalshi is capturing the regulated, institutional, and compliance conscious US market, while Polymarket is capturing the high-frequency, crypto native, and globally decentralised audience. The combined $7.4 billion in monthly volume between them proves that the demand for event contracts is immense. This is the moment prediction markets move from a niche hobby to a major new vertical at the intersection of iGaming, social media, and finance.
