Lekander, who has been shorting Tesla's stock since 2020, stated in an interview with CNBC that he believes the company could "go bust" and foresees the stock plummeting to $14.

Lekander's comments come following Tesla's disappointing vehicle delivery figures for the first quarter of the year. The automaker reported delivering 386,810 vehicles, which fell significantly below even the lowest market estimates. This downward trend has raised concerns about a potential price war, fierce competition from Chinese rivals, and weakening demand for Tesla's electric vehicles.

Describing Tesla's bubble as possibly the largest stock market bubble in modern history, Lekander, managing partner at investment management firm Clean Energy Transition, believes that the recent delivery figures mark the beginning of the end for Tesla. He points to Tesla's reliance on strong revenue growth, vertical integration, and direct-to-consumer sales as a problematic business model that may falter in the face of declining sales.

Lekander's negative outlook on Tesla is supported by his estimation that the company's full-year earnings per share for 2021 will be just $1.40, classifying Tesla as a "no growth" stock. He suggests valuing Tesla at 10 times forward earnings, compared to the current valuation of around 58 times forward earnings.

If Lekander's prediction were to materialize, with Tesla's stock reaching $14, it would represent a staggering 91% downside from its most recent closing price. Tesla's shares have already fallen by over 30% this year, raising concerns among investors and analysts alike.

While Lekander's bearish stance on Tesla is not unique, with a growing chorus of negative voices emerging, there are still those who remain bullish on the company's prospects. Ark Invest, led by Cathie Wood, recently purchased Tesla stock for some of its funds, showing continued support for the electric vehicle manufacturer.

However, critics of Tesla's high valuation and rising competition echo Lekander's concerns. Richard Windsor, founder of Radio Free Mobile, called Tesla's roughly $500 billion valuation "ludicrous" given the current landscape of increased competition. Several analysts, including those at HSBC and TD Cowen, have also lowered their price targets on Tesla's stock.

The future of Tesla remains uncertain, with conflicting opinions and a volatile market contributing to the ongoing debate. As for Elon Musk's response to Lekander's comments, Tesla was not immediately available for comment when contacted by CNBC.

In the meantime, investors and industry experts will closely monitor Tesla's performance in the coming months to assess whether Lekander's predictions hold any weight and what lies ahead for the electric car giant.
