Kalshi congressional markets pass 137.3M contracts traded, with 3.0M changing hands in 24 hours

Congressional trading snapshot

Kalshi’s congressional markets reached 137.3M contracts traded, with 3.0M changing hands over 24 hours, according to the supplied headline snapshot published Oct 14, 2026 · 8:54 AM ET. The accompanying summary says there had been no significant new platform headline in the preceding 15 minutes.

A narrower listing on predictionmarketspicks.com, covering the 2026 midterms’ balance of power in Congress, reports 39125k contracts traded and 29649k open. The supplied material does not explain how that listing relates to the larger congressional-market total.

Prices and open interest

According to predictionmarketspicks.com, the excerpt includes D-House, R-Senate; Republicans sweep; and R-House, D-Senate outcomes. It displays four price/open-interest pairs: 61 ¢ with OI 2929k; 30 ¢ with OI 2205k; 11 ¢ with OI 15124k; and 1 ¢ with OI 9391k.

The extracted listing does not unambiguously connect every price to an outcome, so it cannot support a reliable ranking of those scenarios. Nor does it provide an earlier observation against which to measure price changes or a shift in open interest.

What it means for prediction markets

• The 137.3M cumulative total and 3.0M in 24 hours describe trading activity, not the direction of traders’ congressional expectations.
• The 39125k contracts traded and 29649k open belong to the specific balance-of-power listing; they should not be treated as interchangeable with the broader headline figures.
• Without clearly aligned outcome labels or historical comparisons, the excerpt does not establish which political scenario gained ground.
