San Francisco edges Buffalo on Kalshi but shares Polymarket’s top price

Rivo tracks the Super Bowl LXI board side by side on Kalshi and Polymarket, with San Francisco at 14 percent on both venues and Buffalo at 13 percent on Kalshi against 14 percent on Polymarket. The Kansas City Chiefs are priced at 8 percent on Kalshi and 9 percent on Polymarket.

According to Rivo’s Nov 6, 2026 update, published at 9:15 PM ET, the San Francisco 49ers led Kalshi’s Super Bowl LXI market at 14 percent. The Buffalo Bills and Chicago Bears were each at 13 percent.

The comparison across Kalshi and Polymarket showed San Francisco at the same price on both platforms, while Buffalo and the Kansas City Chiefs had slightly higher readings on Polymarket.

Two venues, different gaps

San Francisco stood at 14 percent on Polymarket as well as Kalshi, according to Rivo. Buffalo was also at 14 percent on Polymarket, matching San Francisco there despite trailing by one percentage point on Kalshi.

Kansas City was priced at 8 percent on Kalshi and 9 percent on Polymarket. Its gap behind San Francisco was therefore six percentage points on Kalshi and five on Polymarket.

What it means for prediction markets

  • The venue changes the comparison: San Francisco held a one-percentage-point advantage over Buffalo on Kalshi, but the two were level on Polymarket.
  • Small differences recur: Buffalo and Kansas City were each one percentage point higher on Polymarket than on Kalshi.
  • The snapshot has limits: The supplied figures do not include a Polymarket price for Chicago or earlier prices, so they do not establish a cross-platform comparison for the Bears or a trend over time.
