Carvana shares are headed for a double-digit decline on the week, with a federal probe targeting billionaire Mark Walter fueling uncertainty over the fate of his minority position in the company. Tuesday's session saw the stock shed more than 7%, extending losses from a comparable drop the day before; a mild bounce Wednesday left shares still roughly 10% in the red for the week.

Federal prosecutors and the Securities and Exchange Commission have opened an investigation into Walter and companies tied to his financial empire, focusing on whether certain financial relationships were hidden while more than $20 billion moved through insurance firms under his control, according to CNBC. Four entities have emerged as the central focus of the inquiry — Miami-based ABS Capital, investment firm Amistad Financial, commercial real estate broker Bradford Allen, and Hudson Trading — each of which allegedly served as a conduit for loans that Walter's insurance companies extended to other parts of his business network, according to Fortune.

Walter, the chief executive officer of Guggenheim Partners and controlling owner of the LA Lakers, indirectly controls CVAN Holdings LLC, which owned 8% of Carvana's Class B common stock as of March 10, according to CNBC. He has agreed to sell the Lakers franchise for $12.5 billion amid the probe. The scrutiny has prompted investors to consider what might happen to his Carvana position if the investigation forces him to raise cash.

Carvana's March proxy statement also disclosed that in June 2025, a private consumer products company granted Carvana a warrant for shares of its common stock, which Carvana valued at $1.5 million as of year-end 2025, with portions vesting through 2029 tied to performance goals. Carvana said Walter "has a substantial ownership interest in the warrant issuer."

Herb Greenberg, an investor who writes on Substack, said the Walter-Carvana link had largely gone unnoticed until the probe brought it to light. "That's been out there and because it's already been disclosed, it fell under the radar oddly and nobody paid attention," Greenberg said. "What happens when he has to sell and who's going to buy it?"

Selling by a company insider may have compounded the stock's struggles this week. Carvana director Ira J. Platt disclosed the sale of 30,000 shares at prices around $74, a regulatory filing shows, bringing in approximately $2.1 million through the exercise of options that were scheduled to expire in 2027.

Carvana, headquartered in Tempe, Arizona, did not respond to a request for comment.
