Tesla's stock price drops 6% following news of a delayed robotaxi unveiling.

• In August, Tesla CEO Elon Musk will unveil the company's robotaxi.
• According to Bloomberg, the unveiling has been pushed to October.
• Tesla shares experienced a 7% decline on Thursday, following an 11-day streak of gains.

On Thursday, shares of the electric vehicle manufacturer dropped approximately 6% after Bloomberg reported that the company had postponed the reveal of its Robotaxi by two months.

Tesla has postponed the launch of its robotaxi from August 8 to October to allow more time for the project team to create prototypes, according to Bloomberg's sources.

Tesla didn't immediately respond to CNBC's request for comment.

Tesla's stock plummeted on Thursday, despite a 11-day rally that was driven by a better-than-expected deliveries report for the second quarter. This decline erased the stock's gains for the year. However, the shares are now trading in the red for 2024, a year marked by significant layoffs and declining sales due to an aging lineup of EVs and intensified competition in China.

For years, Tesla CEO Elon Musk has pledged to deliver a robotaxi to shareholders. In 2015, he predicted that Tesla's vehicles would achieve "full autonomy" within three years. In 2016, Musk stated that Tesla would be capable of sending one of its cars on a cross-country drive without any human intervention by the end of the following year.

In 2019, Musk promised institutional investors that Tesla would have 1 million robotaxi-ready vehicles on the road by 2020. However, the company has not yet delivered a robotaxi, autonomous vehicle, or technology that can turn its cars into "level 3" automated vehicles. Meanwhile, companies like Waymo and Cruise, owned by Alphabet, have surpassed Tesla in their progress towards autonomous vehicles.

In April, following a lackluster first-quarter earnings report, Musk restated his vision for Tesla as a company focused on creating profitable robotaxis and a self-driving transportation system.

Musk stated on the earnings call that if someone does not believe Tesla will solve autonomy, they should not invest in the company. The company will report its second-quarter results later this month.

Tesla's "unveil" dates do not necessarily indicate a prompt release of a new product for commercial use. For instance, Tesla unveiled its fully electric heavy-duty truck, the Semi, in 2017 and started delivering it only in December 2022.
