At least one prominent investor remains bullish on Tesla (NASDAQ:TSLA).

Cathie Wood’s Ark Invest Management forecasts that the stock of electric vehicle maker Tesla will reach $3,000 U.S. by 2025, up from its current price of $655 U.S. At that price, the company would be worth almost $3 trillion U.S., based on the number of shares currently outstanding.

Ark’s new price target is based on the fact that the investor believes there’s a 50% chance of Tesla achieving fully autonomous driving within five years, which could allow the company to scale its planned “Robotaxi” service.

Ark Invest also believes in Tesla’s proposed insurance business, believing the offering could be rolled out to several U.S. states in the next few years with better-than-average margins. Ark’s model didn’t incorporate Tesla’s utility energy storage or solar business, nor did it consider future price fluctuations for Tesla’s Bitcoin holdings.

Cathie Wood has been among Tesla’s most ardent supporters, holding large stakes of the company in her flagship funds. When Tesla shares saw a pullback in February, Ark Invest bought more shares of the company.

According to Ark’s new model, in the best-case scenario, Tesla could reach $4,000 U.S. per share in 2025, and in the worst case, $1,500 U.S. The company forecasts Tesla’s unit sales to be between five million and 10 million vehicles by 2025.

The $3,000 U.S. target is far higher than any analyst who covers the company, the highest being $1,200 U.S. among estimates compiled by Bloomberg Markets. Fueled by zealous supporters, Tesla shares rose more than 740% last year, the best performance on the S&P 500.
