Who Is Favored to Win?
The San Francisco 49ers are favored in Week 3, largely because of home-field advantage. Still, the Cardinals have a real chance to pull off the upset, especially with key 49ers injuries to quarterback Brock Purdy and tight end George Kittle. Final injury reports for both teams will provide more clarity as kickoff approaches.
What's the Point Spread?
The Week 3 point spread for Cardinals vs 49ers is currently San Francisco -3 and Arizona +3. With both teams undefeated, these odds could shift leading up to kickoff. For example, the Cardinals opened at +3.5, but their line improved after back-to-back wins.
What's the Moneyline?
The moneyline for Cardinals vs 49ers is set at AZ +136 and SF -162. Betting $100 on -162 would earn $61.73 plus your $100 back if the Niners win. Meanwhile, betting $100 on the Cards would earn you $136 plus your $100 back if Arizona wins straight up.
What's the Over/Under?
The total for the Cardinals vs 49ers Week 3 game is set at 45.5 points. Last season, the teams combined for 47 points in their first matchup and 71 in the season finale. While a high-scoring game seemed likely, if starting QB Brock Purdy is ruled out, we’re leaning toward the under.

Arizona Cardinals Chances to Win vs San Francisco 49ers
The Cardinals have a 48.2% chance to beat the 49ers in Week 3. Their chances are calculated using implied probability based on odds from DraftKings. Here is how it is calculated for each team using +136 odds for the Cardinals and -162 odds for the 49ers:
Cardinals chances: 136 ÷ (136 + 100) * 100 = 57.6%
49ers chances: 162 ÷ (162 + 100) * 100 = 61.8%
However, the above percentages add up to 119.4%. This is due to the vig, which is the house edge for the sportsbook which allows them to profit off the bet. To remove the vig, we simply divide each team's chance by 119.4.
Cardinals chances (after vig): 57.6 ÷ 119.4 = 48.2%
49ers chances (after vig): 61.8 ÷ 119.4 = 51.8%
Note that both of the final team chances above finally equal 100%. Hence, the 48.2% chance to win for the Cardinals.
How Arizona Wins vs San Francisco
The key to beating the 49ers could come down to the Cardinals’ offense. If Kyler Murray can fully leverage his dual-threat ability and the team utilizes its elite receiving talent, Arizona has a path to victory. Tight end Trey McBride will be crucial as a focal point in the passing game, especially in the middle of the field. If the defense can contain San Francisco’s run game and force turnovers, the Cardinals have a real shot at winning.

On the other side, the 49ers will need to contain Kyler Murray and stay disciplined against the Cardinals’ explosive offense. The game could come down to San Francisco’s defense making key stops while the offense relies on running back Christian McCaffrey to control the action.
