Kalshi’s lower S and P 500 bracket edges higher

PredictionMarketPicks shows 764 contracts traded in 24 hours on the bracket with 283,000 contracts in open interest. The neighboring 7,800 to 7,999 bracket fell three cents to 22 cents over the same period.

The Kalshi contract for the S and P 500 to finish between 7,400 and 7,599 on December 31 rose one cent to 11 cents over 24 hours, according to PredictionMarketPicks.

The update, published Nov 1, 2026 at 12:00 AM ET, showed a price increase for that year-end range alongside a decline in the higher 7,800 to 7,999 bracket.

Trading activity and price divergence

PredictionMarketPicks recorded 764 contracts traded over 24 hours in the 7,400 to 7,599 bracket, with open interest of 283,000 contracts. Those figures distinguish activity during the reporting window from the outstanding contract total.

Over the same period, the 7,800 to 7,999 bracket dropped three cents to 22 cents, according to PredictionMarketPicks. Despite moving in opposite directions, the higher range remained priced at twice the lower range.

What it means for prediction markets

  • The 7,400 to 7,599 outcome gained ground in price, while the 7,800 to 7,999 outcome lost ground over the same 24 hours.
  • Open interest of 283,000 contracts should not be confused with recent turnover: reported 24-hour trading totaled 764 contracts.
  • These two brackets alone do not establish how pricing shifted across the full set of December 31 outcomes.
