Kalshi’s year-end S and P 500 bracket falls to 21 cents

PredictionMarketPicks lists the 7,800 to 7,999 bracket as the biggest mover among Kalshi economics markets in its November 1 snapshot, down three cents to 21 cents. The bracket traded 1,008 contracts in 24 hours with 290,000 contracts in open interest.

A Kalshi contract covering the S and P 500 finishing between 7,800 and 7,999 on December 31 fell three cents over 24 hours to 21 cents, according to PredictionMarketPicks.

The outlet identified that bracket as the biggest mover among Kalshi economics markets in its November 1 snapshot. The update was published Nov 1, 2026, at 1:00 AM ET.

Trading activity and outstanding positions

The bracket recorded 1,008 contracts traded over 24 hours, according to PredictionMarketPicks. Open interest stood at 290,000 contracts.

Those figures distinguish trading during the latest 24-hour period from outstanding positions. The supplied snapshot does not include prices for other brackets or an explanation for the decline.

What it means for prediction markets

  • The three-cent decline marks a lower market price for the specific 7,800 to 7,999 year-end outcome, not necessarily a shift toward a lower index finish overall.
  • Without prices for neighboring brackets, the snapshot cannot show where expectations moved across the broader range of possible outcomes.
  • The 1,008-contract trading volume and 290,000-contract open interest provide activity context, but do not establish what drove the repricing.
