Buffalo is favored on the strength of raw production — more points, more total yards, a heavier moneyline price. But Detroit wins the situational battles that tend to flip close games: an elite 80.0% red zone conversion rate and a 38.5% third-down clip, both well clear of Buffalo’s 33.3% marks in the same categories. A $10 trade on the Bills profits just $4.46 if Buffalo closes it out; that same $10 on Detroit pays $18.50 if the Lions spring the road upset — exactly the scenario where bonus capital from code BROAD stretches the furthest.

Frequently Asked Questions
What is the Polymarket promo code?
BROAD. Entering it at sign-up and depositing $10 minimum triggers an automatic $50 bonus.
How much do I need to deposit to unlock the $50 bonus?
Just $10. A single $10 first-time deposit is enough to fully unlock the bonus tied to code BROAD.
Do I need to enter promo code BROAD before or after I deposit?
Before. Enter BROAD during account registration, ahead of your first deposit, so the system links the code to your account before the $10 deposit clears.
Do I need a separate bonus code in addition to BROAD?
No. BROAD is entered once at sign-up. There’s no second referral code, no manual redemption form, and no support request needed afterward.
How fast does the $50 bonus appear after I deposit?
It’s automatic — the bonus credits as soon as the $10 deposit clears, with no waiting period or wagering requirement attached.
Can current Polymarket users redeem code BROAD?
No. It’s strictly a new-user welcome offer for accounts that have never deposited on Polymarket before.
Does claiming the bonus require identity verification?
Yes. Standard ID verification is part of account setup on Polymarket, separate from and in addition to entering the promo code and making the $10 deposit.
Is Polymarket a sportsbook or a prediction market?
It’s a prediction market. Instead of placing fixed-odds bets with a bookmaker, users buy and sell shares tied to the outcome of real-world events, including NFL games like Lions vs. Bills.
Can I use the BROAD bonus on a market other than Lions vs. Bills?
Yes. The $50 bonus is a general account credit tied to registration and deposit, not to any single game, so it can be applied to Lions-Bills markets or any other market on Polymarket.
Who is favored in Lions vs. Bills, and by how much?
Buffalo is favored at home by -4.5 on the spread, a 66.3% implied win probability. Detroit is the road underdog at 33.7% implied.
What time and where is tonight’s Lions-Bills game?
8:15 PM ET on September 17, 2026, at Highmark Stadium in Orchard Park, NY — an outdoor, turf-surface venue seating roughly 63,000.
Where can I stream Lions vs. Bills?
Exclusively on Amazon Prime Video.
