Kalshi and Polymarket set different point spreads for Sunday's Bengals game

Different spread lines across venues

Cincinnati is the focus of a cross-platform difference ahead of the Titans vs Bengals game on Sunday, Nov. 1, at 1:00 PM ET. According to Rocky Top Insider’s odds comparison, Kalshi centres its Bengals spread ladder on 10.5 points, while Polymarket defaults to 13.5.

The comparison, published Oct 31, 2026 · 8:54 PM ET, places those two displayed thresholds 3 points apart. That makes the selected spread—not simply the team name—important when comparing the venues.

The available summary indicates that Cincinnati is priced to win, but it cuts off before providing a price or implied probability. It also supplies no contract-level prices for either spread threshold.

The difference therefore establishes a contrast in the lines being highlighted, not a quantified disagreement over Cincinnati’s chances. Without prices for matching thresholds, the supplied material does not show how either venue values the same outcome.

What it means for prediction markets

• Match the threshold first. Cincinnati at 10.5 points and Cincinnati at 13.5 points represent different spread outcomes; their prices would not be directly interchangeable.
• A default is not a probability. The highlighted lines alone cannot establish which venue assigns Cincinnati a higher chance of covering a given spread.
• The pricing evidence is incomplete. The supplied summary supports identifying the venue split, but not calculating an implied-probability gap.
