Tesla's shares sank nearly 7% in premarket trading as the EV giant grapples with sinking sales and mounting doubts over its future under CEO Elon Musk, deepening investor anxiety after another shaky quarter.

In 2020, Tesla controlled nearly 80% of the U.S. market, based on data from Experian. By 2022, that was down to 65.4%, followed by 55% in 2023. This year, per Cox Automotive, that share continues to decline, hovering around 45% as of July 11.

Elon Musk has finally confirmed that Tesla’s new ‘affordable’ electric car is just going to be the Model Y in a cheaper format. Musk has ended months of speculations and misinformation, which he partly created, about Tesla’s upcoming cheaper electric vehicle model.

Tesla's Model Y has been the dominant player in the segment for years, but Nissan’s Ariya offers a persuasive alternative.
