Carvana ties up with Bezos-backed Slate Auto as it plans new car sales

Walter also holds a major stake in Carvana. He owns 8% of the company’s Class B common stock and 1% of the overall voting power. Only Garcia III and his son, Ernie Garcia II, have more control.

It’s possible Carvana has already revealed some details about the Slate tie-up to investors without naming the startup.

In March, Carvana revealed in a regulatory filing that it had been granted a warrant to purchase shares of a “private consumer products company” in June 2025. Carvana did not name the company but said the aggregate value of the warrant was $1.5 million at the end of 2025 and that it “vests in tranches through 2029 based on jointly determined performance goals.” Carvana noted that Walter has a “substantial ownership interest in the warrant issuer.”

Carvana did not say whether this was a reference to Slate or another company in Walter’s portfolio.
