THE FUSE

Jabari Smith Jr. grew up inside the business of professional basketball, and he has moved quickly to build his own stake in it. The Houston Rockets forward, still just 22, has assembled a personal fortune of roughly $40 million only a few seasons into his career, drawn from a guaranteed rookie contract, a nine-figure extension and an endorsement deal with one of the world's largest sportswear brands. He is not a billionaire, and it would be wrong to call him one, but he is an unusually well-capitalized young athlete with his highest-earning years still ahead of him.
