Polymarket Promo Code ALCOM: Grab a $25 Bonus for NFL Week 5 After a $10 Deposit

If you’ve been curious about prediction markets but haven’t taken the plunge yet, Polymarket is rolling out a tempting welcome deal. Pop in the promo code ALCOM when you sign up, drop a modest $10 deposit, and—boom—a $25 trading credit lands in your account. No hidden hoops, no required first trade; just a straightforward bonus to get you started.

Of course, there are a few fine‑print points to keep in mind. The $25 credit can’t be withdrawn, transferred or exchanged for cash, and you have to be at least 18 years old and a first‑time customer. Also, if you live in Nevada, the Polymarket US platform isn’t available there. Aside from those constraints, the offer is as simple as it gets.

Claiming the bonus is a three‑step dance: click the official Polymarket link, create an account, and complete the mandatory identity verification. When you’re prompted for a promo code, type in ALCOM, then fund your account with $10 or more. Once the deposit clears, the $25 bonus appears automatically.

What can you actually do with that credit? Polymarket doesn’t work like a traditional sportsbook. Instead of betting on a game directly, you trade event contracts that settle at $1 for a win or $0 for a loss. The price of a contract mirrors the market’s implied probability, so a contract priced at $0.60 suggests a 60 % chance of the outcome happening.

Since NFL Week 5 is just around the corner, let’s peek at a couple of the most talked‑about markets. The Indianapolis Colts are heading to Pittsburgh to take on the Steelers, both sitting at 2‑2 records. Polymarket currently prices the Steelers at a 58 % chance to win versus the Colts’ 42 %, but the spread market is tighter—Pittsburgh winning by more than 2.5 points is priced at 52 %. The over/under for total points (43.5) sits dead‑center at 50 %.

On the other side of the country, the Detroit Lions square off against the Arizona Cardinals. Detroit is the clear favorite, with a 70 % implied probability of winning, yet the spread market (Lions by over 5.5 points) is exactly 50‑50, and the over/under (54.5 points) is a shade below at 49 %. In other words, traders are confident the Lions will win, but they’re split on whether they’ll dominate.

These odds make sense when you consider the recent form. The Colts just rolled over Washington 30‑13 in London, with Jonathan Taylor racking up 95 yards and two touchdowns. The Steelers, meanwhile, fell 27‑24 to Cleveland after a near‑comeback. For the Lions, quarterback Jared Goff threw for 412 yards in a loss to Carolina, while the Cardinals are dealing with the fallout from a potential trade involving star receiver Marvin Harrison Jr., who may sit out the game.

Beyond the ALCOM code, Polymarket offers a handful of alternate promos for users in different states: MLIVE, NJCOM, and PENNLIVE each unlock a $25 bonus under the same deposit conditions. It’s worth checking which code works best for you before you sign up.

Finally, a quick reminder: prediction‑market trading is meant for entertainment and carries risk. You could lose your entire deposit, and past performance doesn’t guarantee future results. Trade responsibly, stay within your limits, and enjoy the extra edge that a $25 bonus can give you during NFL Week 5.
