Looking to trade on the 49ers and Chargers matchup Thursday night? The Polymarket promo code SIBONUS unlocks a $20 bonus when you deposit $10 to start predicting outcomes on this Week 2 preseason game. This welcome offer gives you extra capital to explore prediction market promos and evaluate the 49ers and Chargers before kickoff on Thursday, August 20.

How the Polymarket Promo Code SIBONUS Works for the 49ers-Chargers Game

The Polymarket promo code SIBONUS is straightforward: deposit $10 and receive a $20 trading bonus to use on the platform. You'll need to enter the code during registration and complete identity verification with a photo ID and selfie. The bonus applies across all Polymarket markets, meaning you can trade on outcomes related to the 49ers-Chargers game or explore predictions on politics, economics, entertainment, and more.

Here are the key terms and conditions for claiming this offer:

Available in all U.S. states except Nevada
You must be physically located in an eligible state
Enter promo code SIBONUS during sign-up
Minimum deposit of $10 required to activate the bonus
Identity verification with photo ID and selfie is mandatory

Consider this scenario: you deposit $10 and receive your $20 bonus, giving you $30 in trading capital. You predict that the 49ers' secondary will struggle against the Chargers' passing game based on joint-practice reports. If your prediction proves correct, your winnings add to your account balance. If the market moves against you, you've only risked your initial deposit while having the bonus to explore other trades on the game.

The bonus is valid for trading on any Polymarket outcome, whether you're focused on the 49ers-Chargers game or branching into other prediction categories. There are no expiration restrictions mentioned, but you should verify current terms on the platform before claiming.
