Kalshi activity reached peak levels in October, driven by the overall expansion of prediction markets and interest in trading current events. | Source: Dune Analytics.
The prediction markets sector as a whole expanded significantly, crossing $1 billion in monthly volumes for the first time in recent months. Kalshi’s performance, particularly in the last week of October when volumes neared $1 billion, reflects a sustained higher baseline of activity compared to prior periods.
How Do Kalshi Prediction Markets Compare to Polymarket in User Accessibility?
Kalshi prediction markets have carved out a niche by targeting Web2 users, those accustomed to traditional finance apps rather than crypto ecosystems. Unlike Polymarket, which requires cryptocurrency wallets and ownership for participation, Kalshi integrates seamlessly with platforms like Robinhood, lowering entry barriers and accelerating mainstream adoption. This approach has enabled Kalshi to onboard users who might otherwise avoid blockchain-based betting due to complexity or regulatory concerns.

Supporting data from Dune Analytics shows that Kalshi’s non-blockchain model contributed to its edge, with sports bets dominating the volume surge. However, both platforms encountered operational challenges; Kalshi experienced a market outage, while Polymarket maintained API access for seasoned traders during its brief downtime. Experts note that Kalshi’s strategy, while effective, faces scrutiny over aggressive marketing tactics aimed at capturing crypto-savvy users from competitors.
Regulatory clarity plays a pivotal role here. As a CFTC-regulated entity, Kalshi operates within established financial frameworks, appealing to risk-averse participants. In contrast, Polymarket’s on-chain nature introduces volatility tied to crypto markets, though it fosters a dedicated community. According to industry analysts, this accessibility gap could define the platforms’ trajectories, with Kalshi potentially leading in user growth if it sustains its momentum.

Despite these advantages, accuracy remains a concern. For instance, both Kalshi and Polymarket misjudged outcomes in the recent Dutch elections, highlighting the inherent uncertainties in prediction-based trading. Short sentences like these emphasize the need for users to approach these markets with informed caution, relying on diverse data sources rather than singular platforms.
