White Sox vs. Guardians Predictions
Parker Messick has been one of the best pitchers in baseball with a 2.51 ERA and 1.02 WHIP. This is a big advantage for the Guardians against Anthony Kay, whose walk-plus-hit rate puts the White Sox in tough situations.
- White Sox vs. Guardians prediction: White Sox win YES (44%)
White Kay is susceptible to a high walk total, I lean towards it not costing Chicago the win. The Guardians offense has struggled to score this year (27th in runs per game and 29th in slugging).
Lions vs. Bills Predictions
Lions vs. Bills is a matchup between two of the highest scoring teams in Week 1. Josh Allen led the Bills to a 36-31 win over Houston in Week 1, while Jahmyr Gibbs led the Lions to a 31-30 win over the Saints in overtime.
- Lions vs. Bills prediction: Bills win YES (67%)
Claim Polymarket promo code ACTION and $50 in bonus funds to trade my Lions vs. Bills prediction above. The Lions' defense is injured in the secondary, and I expect Allen to exploit that weakness. I also expect a bigger impact from James Cook, who was held in check against the Texans.
LSU vs. Ole Miss Predictions
LSU vs. Ole Miss is more than just a matchup between two top-ten ranked teams with championship aspirations. This is the first time Lane Kiffin has returned to Ole Miss since leaving them before the postseason to take the LSU head coaching job.
- LSU vs. Ole Miss prediction: Ole Miss win YES (42%)
Sam Leavitt's four interceptions through two games are a concern heading into a hostile environment, especially after LSU's ugly showing against Louisiana Tech. Add the Lane Kiffin revenge-game atmosphere in Oxford and this feels like a one-score Rebels win.
Polymarket Promo Code ACTION FAQs
What is the Polymarket promo code? The Polymarket promo code is ACTION. New users aged 18 and over enter it in the referral field during registration on the Polymarket US app to unlock $50 in bonus funds. The code applies at sign-up only, so it cannot be added to an existing account afterward.
Do you need to place a trade to get the $50? No. A $10 deposit is all that triggers the bonus, which sets this apart from most prediction market offers that ask you to trade your own money first. Depositing more than $10 does not increase the bonus.
Can you withdraw the $50 straight away? Not directly. The bonus lands as trading credit, so you put it to work in the markets rather than cashing it out. Anything those positions make settles as withdrawable cash, so the credit does the lifting and the profit is yours.
18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See polymarket.com/tos for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated exchange and clearing organization.
