This is the tightest matchup of the slate, and the experts flag several value angles. The Over 8 is the strongest read at 53%, with Kalshi and Polymarket priced close (1.97 and 1.96). San Francisco’s moneyline is the value side on the platforms, with Polymarket’s 2.04 clearing the experts’ 52% read. The Giants at -1.5 (2.56 on Polymarket) is the higher-variance play for those backing a margin win.

The bottom line

Experts lean San Francisco in a genuine coin-flip, with the Over 8 and the Giants moneyline both flagged as value. Polymarket carries the better San Francisco moneyline price, while the over is near-identical across both platforms.
