Janie Buss returns to racing, building her own legacy at Del Mar

A Lakers name, but a racing identity of her own

Janie Buss did not come back to racing as a celebrity owner looking for a one-off cameo. She returned as someone who already knew the backstretch, the rhythm of a race day, and the satisfaction of building something that stands apart from the family name she carries. Purple Rein Racing is the point of the story: a stable that nods to the Lakers’ purple and gold, but is meant to be more personal, more durable, and more hers.

That matters in horse racing because ownership is not just branding. Owners shape the horses in the barn, the races on the calendar, the level of commitment behind the stable, and the kind of horseman relationships that keep a program relevant over time. Buss is not simply lending a famous surname to the sport. She is trying to create a racing operation with its own record, its own partners, and its own reputation.

Del Mar was the classroom

The origin story runs through Del Mar, where Buss spent childhood summers with her brother Jimmy, taking the tram onto the backstretch and soaking up the world behind the scenes. While her parents moved from beach mornings at Torrey Pines to first post, Buss was learning the language of the game from the inside out: pony riders, feed rooms, barns, and the daily traffic that makes a racetrack feel like a small city.

That memory gives her current involvement a different texture. For Buss, Del Mar is not just a scenic racing backdrop on the Southern California circuit. It is the place where she first learned that the sport lives in the details, in the daily labor and the relationships that outsiders rarely see.

From quarter horses to Thoroughbreds

Before Purple Rein Racing became a Thoroughbred name, Buss had already built an equine identity of her own. She showed quarter horses and paint horses and reached the top 10 nationally in competition, proof that horses were never just a family pastime or a nostalgic memory from childhood summers.

That matters because it explains why her return to racing feels deliberate rather than decorative. Buss did not discover horses after her basketball profile was established. She stayed connected to them through competition, and that continuity helps Purple Rein Racing read less like a side project and more like the next chapter of a lifelong habit of participating in horse culture.

Purple Rein Racing was built to last

Purple Rein Racing was first reported in 2017 as Janie Buss’s horse-racing operation, with Doug O’Neill named as trainer. The enterprise was later organized as Purple Rein Racing, LLC in California, filed on July 17, 2018. Those details matter because they show a stable that took shape as a real operation, not just a headline.

By June 2024, BloodHorse reported that Buss had launched Purple Rein Racing eight years earlier and had a front-row seat as a Lakers co-owner after Jerry Buss died in 2013. The “purple and gold” reference is obvious, but the point of the stable goes deeper than the color palette. Buss has framed racing as a place to invest, participate, and make a difference, which gives the operation a purpose beyond family symbolism.

The numbers say this is not a novelty stable

Purple Rein Racing’s record has become substantial enough to stand on its own. Equibase lists the Buss-owned operation with 111 career starts, 15 wins, 15 seconds, 11 thirds, and $764,585 in earnings as of May 23, 2026. Equibase also identifies Purple Rein Racing as a multiple graded-stakes-winning owner, while the partnership of Purple Rein Racing and Mark D. Davis is listed as a multiple graded-stakes-placed owner.

Those are the kinds of numbers that shift a stable from curiosity to credibility. In a sport where many ownership stories fade after the first bright moment, Purple Rein Racing has stayed active, visible, and productive across several seasons. That sustained presence is what gives Buss’s racing identity weight.

The horses that gave the stable its shape

J B Strikes Back provided one of the clearest examples of what Purple Rein Racing can be. On December 26, 2024, the horse won the Grade II Laffit Pincay Jr. Stakes at Santa Anita by 1 1/4 lengths for trainer Doug O’Neill and owner Purple Rein Racing. Santa Anita reported that the horse was making his stakes debut, and BloodHorse noted that O’Neill credited Janie Buss for being eager to run the horse after earlier wins against easier company.

That race mattered because it showed ambition, not caution. Buss and O’Neill were willing to step up when the horse earned the chance, and the result placed Purple Rein Racing on one of Southern California racing’s most visible stages.

Mucho Del Oro added another layer to the stable’s profile. O’Neill and Purple Rein Racing claimed the horse for $50,000 in June 2023, and he later went on to win graded stakes, including the Grade III San Simeon Stakes and the Grade III Daytona Stakes. Those performances gave Buss’s barn a tangible stakes presence and proved that the stable could identify, claim, and develop a horse capable of competing well beyond allowance-company success.

Why this return matters at Del Mar and beyond

Buss’s return to racing is meaningful because it connects memory to modern ownership in a sport that depends on both. Del Mar gave her early access, but Purple Rein Racing shows what happens when that access turns into sustained participation. She is not merely visiting the game she grew up around. She is helping shape the shape of her own stable within it.

That is the larger story behind the Lakers connection. The family name opens the door, but the racing operation is being built on its own terms: with Doug O’Neill, with horses that have already won graded stakes, with a record that shows durability, and with an owner who knows that horse racing rewards people who stay involved long enough to matter.
