49ers vs Seahawks Expert Picks & Betting Splits for Week 5

• The Seahawks boast a dominant nine-game home winning streak entering this pivotal NFC West tilt
• Despite heavy public ticket counts backing the underdog 49ers, the true betting value lies in the home side’s moneyline
• With two highly efficient offenses averaging a combined 56.7 points, taking the Over is a premium play

An undefeated San Francisco 49ers (4-0, 3-1 ATS) squad heads to the Pacific Northwest for a diabolical track meet against the division-rival Seattle Seahawks (3-1, 1-1-2 ATS). Kickoff for this crucial NFC West tilt is slated for 1:25 PM PT / 4:25 PM ET Sunday at Lumen Field, with FOX carrying the broadcast.

The 49ers bring a flawless 4-0 record into Seattle, operating as a dangerous road underdog. A win on Sunday would give them a two-game lead on the Seahawks and at least two on the Rams. I will break down the crucial market splits, analyze roster mismatches, and provide actionable sports betting picks to help you beat the books.

49ers vs Seahawks Odds

Odds as of October 11 at BetMGM.

Oddsmakers opened the spread at Seahawks -3, and it has remained at that number. Although San Francisco +3 was originally priced at -115 with Seattle -3 at -105, and now the juice has flipped.

The total saw slight upward movement, climbing from an opening mark of 45.5 to the current 46.5.

A $10 wager on the road underdog moneyline pays out $23.70 total, while a $10 bet on the home favorite yields $16.10.

49ers vs Seahawks Prediction

Moneyline Pick: Seahawks (-163/62% at Novig)

I am taking a definitive stance on this divisional clash by backing the home favorite on the moneyline. It is notoriously difficult to bet against the Seahawks at Lumen Field, where they are riding a massive nine-game home winning streak and boast a dominant 13-1 straight-up record over their last 14 games overall. Mike Macdonald’s squad has also gained the upper hand in head-to-head competition, winning three of their last four meetings against San Fran.

While San Francisco plays exceptional football on the road with a 6-1 mark in their last seven away dates, Seattle’s defensive disruptiveness is built to derail timing-based passing offenses. The Seahawks’ defensive front has already generated eleven sacks and six interceptions through four games, forcing eight total turnovers.

With Seattle pushing spreads with two pushes already this season in a 1-1-2 ATS start, taking the home side straight up completely eliminates the danger of a backdoor cover on the three-point spread. That provides high-probability leverage, and buying Yes shares on the Seahawks to win at 62 cents on Kalshi comfortably edges out standard sportsbook juice.

Game-Total Pick: Over 46.5 Points (+104/49¢ at Kalshi)

Offensive efficiency dictates a play on the Over in this spot. The 49ers average a blistering 30.5 points per game and convert 57.5% of their third-down attempts, sustaining high-volume scoring drives while finding the end zone on an elite 84.6% of their red-zone trips.

Seattle’s passing attack has hit its stride under Sam Darnold, averaging 26.3 points per contest and hitting the Over in consecutive weeks with combined totals of 64 and 53 points against Washington and the Chargers. Across all contests in 2026, these two squads boast a combined scoring average of 56.8 points per game, meaning both offenses consistently generate chunk plays and capitalize on short fields created by aggressive defensive pressure.
