Cincinnati win odds align as platforms show different spread benchmarks

Kalshi prices Cincinnati at 87 percent and Polymarket at 86 percent for the November 1 game against Tennessee, but Kalshi's most traded spread contract is the 10.5 point line with more than 650,000 contracts traded, while Polymarket's default spread line sits at 13.5 points.

Kalshi and Polymarket show similar probabilities for Cincinnati to beat Tennessee in the November 1 game, but their highlighted spread contracts differ, according to Rocky Top Insider.

The report, published Oct 31, 2026 at 9:00 PM ET, puts Cincinnati at 87 percent on Kalshi and 86 percent on Polymarket—a one-percentage-point gap.

Spread benchmarks sit three points apart

Kalshi’s most-traded spread contract is the 10.5-point line, with more than 650,000 contracts traded, according to Rocky Top Insider. Polymarket’s default spread line is 13.5 points.

Those benchmarks are three points apart, but they reflect different selection criteria: trading activity on Kalshi and the default display on Polymarket. The supplied figures therefore do not establish a like-for-like difference in spread pricing.

What it means for prediction markets

  • Winner probabilities are closely aligned: Cincinnati’s 87 percent probability on Kalshi is just above its 86 percent probability on Polymarket.
  • Spread comparisons require care: The 10.5-point and 13.5-point contracts concern different thresholds; their separation alone does not demonstrate a pricing discrepancy.
  • Activity data are limited: More than 650,000 contracts traded identifies substantial activity at Kalshi’s 10.5-point line, but no comparable Polymarket volume is provided.
