Comparing the same events

PolymarketTrader matched 8 events available on both exchanges as of November 7, 2026. Its comparison uses public data from Polymarket and Kalshi and is refreshed twice a day.

The reporting was published on Nov 7, 2026 at 9:30 AM ET. That timing matters when interpreting the figures: they describe the reported comparison, rather than a continuously updated measure of the exchanges’ prices.

A larger gap in the presidential market

The outcome for Democrats to win the 2028 presidential election was priced at 67.5 percent on Polymarket and 65.5 percent on Kalshi, according to PolymarketTrader.

That 2.0-point difference is twice the reported average across the 50 matched outcomes. For this outcome, Polymarket’s price was higher; the summary does not establish whether either exchange was consistently higher across the broader comparison.

What it means for prediction markets

The 1.0-percentage-point average provides a benchmark for pricing differences within the matched sample, not across every market on either exchange.
The 2028 presidential outcome illustrates how an individual contract’s gap can exceed the sample average.
Twice-daily refreshes leave the comparison tied to discrete snapshots. The provided figures do not show how long the differences persisted.
