Cooper Flagg Launches NBA-Star Card Shop With Kevin Hart Announcement

Cooper Flagg just dropped a major off-court move: he and his cousin are opening a trading-card shop back home.

What happened?

On 21 Jul 2026, Flagg told Kevin Hart during the “Cold as Balls” ice-bath interview that he and his cousin are launching a card shop. The Mavericks released a preview of the chat, showing Flagg casually mentioning the plan. Hart cut in fast: “That’s a big deal, man.” The clip gave no name, location or opening date for the shop.

Why it matters for Cooper Flagg

Flagg isn’t just another athlete slapping his name on a business. He’s already the face of Topps’ 2025-26 basketball set-the cover athlete and the rookie-class leader. Topps called him the leading figure in its return to fully licensed NBA cards. His on-court success only stoked collector demand: he averaged 21.0 points, 6.7 rebounds, 4.5 assists, 1.2 steals and 0.9 blocks over 70 games for Dallas. Those numbers earned him the 2025-26 NBA Rookie of the Year award and a unanimous spot on the All-Rookie First Team.

A family project rooted in Maine

Flagg made the disclosure while Hart asked how he’s handling sudden fame. Flagg said starting the shop with his cousin keeps him tied to life away from the NBA spotlight. He grew up in Newport, Maine, before Montverde Academy and one season at Duke. The Mavericks’ clip didn’t confirm whether “back home” means Maine or if Flagg will run daily operations.

What comes next?

The shop’s details remain under wraps. Flagg didn’t name the cousin or the location. Yet the venture lands at a perfect moment: his rookie cards are red-hot, his Topps cover is already a collector staple, and his Rookie of the Year hardware adds star power. If the shop opens in Maine, it could tap into local nostalgia-and the national card market’s hunger for Flagg-branded product.
