What to Do With the $20 Trade Bonus
The $20 bonus you receive by signing up with Polymarket referral code ACTION stretches further than a sportsbook. Polymarket prices in cents, so a 53¢ contract pays $1. Here is how I encourage you to trade on Polymarket:
- Split your funds into multiple smaller positions instead of one lump trade.
- Trade the second half live. Preseason lines swing hard once the backups enter.
- Sell early since you have the ability to exit a position before the final whistle.
- Mix in a futures market. I hold a small Super Bowl LXI position I bought in July.

49ers vs Chargers Odds on Polymarket and Kalshi
Both prediction markets price this game as close to a coin flip, which is unsurprising given the unknown nature of preseason and how snaps are distributed:
| Market | Polymarket | Kalshi | Sportsbook line |
|---|---|---|---|
| Chargers win | ~53c | ~53c | Chargers -1.5 |
| 49ers win | ~47c | ~47c | 49ers +1.5 |
| Total points | Over/Under 38.5 | Over/Under 38.5 | 38.5 to 39 |
NFL odds are in constant flux due to the live trades your peers are making. The real difference between these two apps worth noting is that Polymarket charges no fee on most of their trades, while Kalshi applies a fee tied to contract price.
My 49ers vs Chargers Pick Today: Chargers Moneyline
Pick: Chargers to win.
Jim Harbaugh and Kyle Shanahan coordinated plans at Tuesday's joint practice, and both teams will send their starters out for one series. With second-string players dominating reps by the middle of the first quarter, quarterback depth could decide this one.
Here is why I land on Los Angeles:
- Chargers QB2 room wins the matchup. Trey Lance and DJ Uiagalelei carried the opener against Houston. San Francisco leaned on Adrian Martinez, who finished 16 of 30 for 159 yards against Tennessee.
- Mike McDaniel knows the opponent. The first year Chargers coordinator ran this exact scheme during his time in Santa Clara.
- Home reps matter in August. Los Angeles opens its home slate off a joint session it won.
I also lean Under 38.5 total points. Rotation heavy preseason football and conservative play calling from both staffs figure to keep the scoreboard quiet.
