49ers stretch clear in the NFC West: 67% on Kalshi, 66% on Polymarket, up 25 points in a week

The San Francisco 49ers’ chances of winning the NFC West stand at 67% on Kalshi and 66% on Polymarket in the latest supplied snapshot, with a weekly increase of 25 percentage points. Those readings put San Francisco clearly ahead and show close agreement between the two venues.

According to iPredicta, the underlying division-market readings were taken on 14 October 2026 at 07:33 UTC. Its weekly change measures the movement in the average of the two platforms’ prices since 7 October 2026—not a separate 25-point increase on each exchange.

A different picture from September

The competitive backdrop includes the LA Rams, who entered the season as Super Bowl LXI favourites before losing their opening game in Australia to the 49ers, according to iPredicta. The Seattle Seahawks are the defending Super Bowl champions, while the Arizona Cardinals are among the league’s least-favoured division contenders.

Earlier pricing showed a much tighter contest. On 13 September, iPredicta recorded Kalshi bid-and-ask quotes of 35 to 36 for the 49ers, 33 to 34 for the Seahawks and 33 to 34 for the Rams. On Polymarket, San Francisco’s quote ranged from a bid of 23 to an ask of 35—a twelve-point spread that made its midpoint less useful as an indication of an executable price.

Reading the snapshot carefully

For the 14 October 2026 reading, iPredicta reported that Polymarket’s NFC West probabilities totalled 102.6%, with $49,544 traded over the market’s life. That total matters when comparing individual contract prices: the displayed probabilities do not form a book adding neatly to 100%.

The source also retains commentary describing all three leading NFC West teams as having at least a 30% chance on Kalshi, which does not align with the supplied headline snapshot. The current figures and their timestamp therefore warrant more weight than that older description. The material does not identify a specific catalyst for the latest weekly move.

What it means for prediction markets

• Agreement is strong: Kalshi’s 67% and Polymarket’s 66% readings present a consistent view of San Francisco as the favourite.
• The weekly move is an average: The reported 25-percentage-point increase uses prices across both venues, measured from 7 October 2026.
• Price quality still matters: September’s wide Polymarket spread illustrates why midpoint probabilities should be distinguished from available buying and selling prices; no current spread is supplied.
• Check the timing: The snapshot supports a clear 49ers lead, but parts of the accompanying source commentary describe an earlier, closer race.
