Bengals win probabilities converge as prediction venues diverge on spread

Cincinnati’s chances of beating Tennessee on November 1 were priced similarly on Kalshi and Polymarket, but the platforms differed on the expected margin, according to Rocky Top Insider.

The outlet’s report, published Nov 1, 2026 at 4:15 PM ET, put Cincinnati’s win probability at 87 percent on Kalshi and 86 percent on Polymarket—a difference of one percentage point.

Spread benchmarks show a wider gap

According to Rocky Top Insider, Kalshi traders centred the spread ladder at 10.5 points, while Polymarket’s default line stood at 13.5 points. Those benchmarks were three points apart despite the closely aligned outright-win probabilities.

DraftKings’ spread was 12.5 points, according to the same report. That placed it between the two prediction-market benchmarks: two points above Kalshi’s centre and one point below Polymarket’s default.

What it means for prediction markets

• Winner and margin are separate questions. The 87 percent and 86 percent prices indicated similar assessments of a Cincinnati victory, without equivalent alignment on the spread.
• The benchmark distinction matters. Kalshi’s spread-ladder centre and Polymarket’s default line describe different reference points; their separation alone does not establish disagreement on an identical contract.
• DraftKings provides another comparison. Its 12.5-point spread sat between the reported prediction-market levels, highlighting the importance of checking the precise margin attached to each outcome.
