Mixing sports gambling, fantasy competition and stock market mechanics, Mojo [launched] in New Jersey Monday with $100 million raised to date. In the app, NFL players—from Tom Brady to Jets rookie Jeremy Ruckert—each have a share price that represents the stat totals they’re expected to accrue over their career. Users can buy, sell or short players at those prices.

Mojo’s founders include entrepreneur and Minnesota Timberwolves owner Marc Lore, as well as fellow T-wolves owner Alex Rodriguez. They’re joined by tech execs Bart Stein and Vinit Bharara.

As Bharara explained in an interview, Mojo is decades in the making.
