Democratic Senate pricing gap persists between Polymarket and Kalshi

Polymarket’s pricing for a Democratic Senate stood 2.4 points above Kalshi’s in the supplied Election Day update, published Nov 3, 2026, at 4:24 PM ET.

The difference had persisted for days and remained in place as the first polls closed. The available material therefore describes a continuing separation between venues, rather than a newly emerging gap.

A pricing difference, not a new catalyst

The update identified no significant new prediction-platform headline in the preceding 30 minutes. Instead, its Election Day political coverage focused on the divergence between the two platforms.

No source links or underlying reporting were supplied. The material does not provide either contract’s absolute price, trading volume or settlement terms, limiting any assessment of why the gap persisted or whether the contracts were directly comparable.

What it means for prediction markets

• Venue matters: The supplied figures put Polymarket 2.4 points above Kalshi on Democratic Senate pricing; neither absolute price is available.
• Persistence is the central observation: The gap lasted for days into the first poll closings, rather than appearing only in the latest update.
• The explanation remains unverified: Without contract terms and trading data, the difference alone does not establish a cause or show which venue better reflects the outcome’s probability.
