San Francisco 49ers @ Los Angeles Chargers 08/20/2026
Two California clubs, a shiny Thursday night at SoFi, and a preseason chess match between two of the NFL’s bluest brands. That’s the setup for San Francisco 49ers @ Los Angeles Chargers in NFL Preseason (Matchday 2), kicking at 10:00 PM ET on Thursday, August 20, 2026. Preseason betting is a different animal—limited starter reps, coach-driven snap counts, and depth-chart auditions make the market swingy. Still, there’s signal here. The Chargers opened preseason with a clean 27-7 road win at Houston, while the 49ers took a 13-19 home loss to Tennessee. Add in joint practices this week, and you’re looking at a Jim Harbaugh outfit that tends to emphasize situational football and execution in August.
The market has this close: Implied probabilities are roughly 49% for L.A. and 56% for San Francisco before removing the juice. That’s a live underdog position with the home side, even if the Niners are correctly priced as a slight favorite. With both staffs prioritizing evaluation over scheme, variance is part of the deal—but that can open the door to value on tight moneylines and modest spreads.

Our 3 betting predictions for San Francisco 49ers @ Los Angeles Chargers
Main Tip: Moneyline – Chargers to win at +104
Market-wise, the Niners at -127 say they’re rightful small favorites, but preseason moneylines compress quickly when the second half becomes about roster spots 40-90. I put San Francisco around 52% and L.A. around 48% to win outright, narrower than the posted prices. That swings the “value” arrow to the Chargers’ side as a short home ‘dog. Justin Herbert won’t be asked to carry volume here, but the combination of defensive tempo and situational offense looks solid enough to push this late. With SoFi’s home backdrop and Harbaugh’s familiar feel for the Niners’ DNA, L.A. has a puncher’s chance—and at a plus price, that’s exactly what we’re hunting. Tip: Chargers moneyline +104.
Pick 2: Spread Pick – Chargers +2.5
As a home underdog in the preseason, the Chargers check a few boxes. Harbaugh has been intentional with his install tempo, and L.A. looked buttoned-up in its opener. If you can grab +2.5 or better, I like L.A. to cover. Why? Depth. The Chargers’ defensive front rotation flashed control last week, and that travels—especially when the opposing offense is splitting reps and protecting the playbook. Special teams also tend to swing August outcomes, and L.A. has emphasized clean operation in the third phase during camp. My number makes this closer to Chargers +1.0 in a neutral preseason setting, so anything above a point is value. Tip: Chargers +2.5 or better to cover.

Pick 3: Totals – Under 38.5 Points
Preseason totals live and die on quarterback rotations, protection, and who’s actually playing on the perimeter. Through one game, L.A. is allowing 7.0 points per contest, while San Francisco scored 13.0 in its opener—both small samples, but they do point toward conservative scripts, red-zone rust, and second/third-unit execution that tends to stall in the high red. Harbaugh’s defense has looked physically fit, and Kyle Shanahan often runs a vanilla call sheet in August to protect his regular-season menu. If you see an over/under in the high 30s (e.g., 38.5), I lean Under. The preseason typically compresses explosive plays as depth pieces rotate. My estimate: around a 54% chance this plays Under a 38.5-type number given the likely QB cadence and limited starter snap counts for both teams. Tip: Under 38.5 or better.
Team Statistics: Chargers trending up at home; 49ers searching for rhythm after opening loss
Los Angeles Chargers (AFC West, preseason form)
- Record and recent form: 1-0 this preseason, winning 27-7 on the road in Week 1.
- Style notes: In the opener, the Chargers paired efficient situational football with crisp special-teams play, keeping Houston off-schedule.
- Division lens: In the AFC West preseason snapshot, the Chargers are 1-0. It’s August, but stacking operational reps matters.
San Francisco 49ers (NFC West, preseason form)
- Record and recent form: 0-1 this preseason after a 13-19 home loss to the Titans.
- Style notes: In the opener, San Francisco’s offense struggled to finish drives, and protection continuity was a theme as the staff cycled bodies. The defense kept a lid on explosives but conceded field position at inopportune times.
- Division lens: In the NFC West preseason slice, the 49ers are 0-1. August is more about depth-chart clarity than standings, but within-division context still matters.
Keyplayer Statistics/Momentum/External Factors
- Chargers head coach Jim Harbaugh brings structure that often shows up in August execution. Ladd McConkey sat in the opener, while depth receivers (like Brenen Thompson and KeAndre Lambert-Smith) pushed for snaps; expect rotation battles to remain a focal point.
- San Francisco’s August includes injury management: Ricky Pearsall’s season-ending knee surgery changes WR depth; Nick Bosa’s knee soreness has been monitored; Dominick Puni in the concussion protocol impacts O-line continuity. George Kittle ramped activity, a positive trend.
- Joint practices in Southern California this week sharpened looks for both staffs, but these sessions can pull some intensity from the game itself.
- Indoors at SoFi eliminates weather noise, favoring clean timing if protections hold.

TrustnBet Tips summed up
Moneyline: Chargers (+104). With my projection around a 52% win chance, the home side offers a slight edge versus a market tilted toward San Francisco at -127. Harbaugh’s structure, the Week 1 crispness, and a stable depth rotation at home check key preseason boxes. Spread: Chargers to cover small numbers. In August, rotations and clean operation matter more than star power. The Bolts’ Week 1 handling of game situations is a green flag against a Niners group juggling injuries and O-line continuity. Total: Lean Under. Joint practices often drain the fireworks, and both staffs are incentivized to evaluate depth and protect key players. That tends to mean conservative calls in high-leverage spots and more field goals than touchdowns.
Why these three? Preseason is about process and depth, not headlines. The Chargers’ process looked sharper in the opener, and Harbaugh’s emphasis on execution should travel from the practice fields into a controlled indoor setting. San Francisco’s personnel notes add uncertainty to protection and rhythm. That combination nudges the moneyline toward LAC, provides spread cover potential in a one-score game, and tilts the total Under with rotations, conservative red-zone choices, and game-management focus front of mind.
