Polymarket still leads U.S. search demand at 57.8% despite Kalshi's trading dominance

Polymarket accounts for 57.8% of U.S. search demand despite Kalshi’s lead in trading, according to Gambling Insider. The snapshot points to a split between search interest and trading activity in prediction markets.

The report, published Oct 14, 2026 at 1:54 AM ET, places Polymarket ahead on the search metric. The available material does not specify the measurement period or how search demand was calculated.

Search interest versus trading activity

Kalshi’s trading dominance is identified in the report’s headline, but the supplied material includes no trading figures. It therefore does not establish the size of Kalshi’s advantage or provide a numerical comparison between the two platforms’ trading activity.

With the full source text unavailable, the finding is narrow: Polymarket leads the reported U.S. search-demand measure, while Kalshi leads on trading. The material does not explain why those rankings differ.

What it means for prediction markets

• Attention and activity are distinct measures. Polymarket’s 57.8% search-demand share should not be read as its share of trading.
• The trading comparison remains unquantified. No supplied figures establish the scale of Kalshi’s lead.
• Methodology matters. Without the search measurement period and calculation method, the snapshot alone cannot establish a trend.
