Vance pricing across two venues

JD Vance stood at 38% in the supplied DeFi Rate summary for the 2028 GOP nominee market, combining prices from Kalshi and Polymarket.

The venue-level readings were 36.5c on Kalshi and 38.8c on Polymarket. According to the supplied summary of DeFi Rate’s odds page, the aggregate figure averages the two venues rather than representing a price available on either one.

The summary identifies the page’s crawl as Oct. 30, 22:26 UTC and its latest observation as Oct. 30, 6:23 PM ET. The accompanying publication timestamp is Oct 30, 2026 · 6:24 PM ET.

The underlying material is limited: the supplied defirate.com source text refers only to a 2026 midterms question about congressional control. It contains no additional reporting on the nomination market, competing candidates or earlier prices, so it does not establish a trend or explain the difference between venues.

What it means for prediction markets

• The aggregate and venue prices are distinct. The reported 38% combines two readings; Kalshi’s 36.5c and Polymarket’s 38.8c are the individual market figures provided.
• This is a snapshot, not evidence of momentum. Without earlier observations, the material cannot show whether Vance’s pricing rose or fell.
• Relative standing remains unspecified. No prices for other candidates are supplied, preventing a comparison of Vance’s position within the field.
