Philadelphia draws heavier Kalshi trading as Detroit holds higher price

PredictionMarketPicks reports the Kalshi contracts on the November 4 Philadelphia-Detroit NBA game drew about 526,000 contracts on Philadelphia at 46 cents and about 237,000 contracts on Detroit at 54 cents in its November 4, 1:20 a.m. EST snapshot, ranking second and sixth by 24-hour volume across all tracked Kalshi markets. Open interest stood at about 433,000 contracts on the Philadelphia side and about 175,000 on the Detroit side.

According to PredictionMarketPicks, Kalshi contracts tied to the November 4 Philadelphia-Detroit NBA game recorded about 763,000 contracts in combined trading volume. The two sides were among the platform’s most-traded sports markets in the outlet’s snapshot.

Volume and prices diverge

Philadelphia accounted for about 526,000 contracts at 46 cents, while Detroit recorded about 237,000 contracts at 54 cents, according to PredictionMarketPicks’ November 4, 1:20 a.m. EST snapshot.

The Philadelphia side ranked second by 24-hour volume across all tracked Kalshi markets. Detroit ranked sixth on the same measure, putting both sides high on the broader market activity list.

Outstanding positions favor Philadelphia

Open interest was also larger on Philadelphia, at about 433,000 contracts, compared with about 175,000 contracts on Detroit, according to PredictionMarketPicks.

The figures show a distinction between trading activity and pricing: Philadelphia had more volume and open interest, but Detroit carried the higher contract price. The report was published on Nov 4, 2026, at 1:30 AM ET.

What it means for prediction markets

  • Activity is not the same as favoritism: Philadelphia’s larger volume did not translate into a higher price in this snapshot.
  • Both sides attracted substantial participation: Their second- and sixth-place volume rankings were across all tracked Kalshi markets, not just sports.
  • The figures are time-specific: Prices, volume and open interest describe the November 4, 1:20 a.m. EST snapshot, rather than subsequent trading or the game’s outcome.
