Tesla's stock suffered a historic $152 billion market value loss following a public social media spat between CEO Elon Musk and former President Donald Trump.
The turmoil coincides with uncertainty surrounding Tesla's ambitious Optimus humanoid robot project after Milan Kovac, the lead developer, announced his departure.
"Milan Kovac, who oversaw the development of Tesla’s ‘Optimus’ humanoid robot posted on social media late Friday afternoon that he was leaving the company."Musk publicly acknowledged Kovac's exit, expressing gratitude and calling it an "honor" to work with him.
"Musk later replied to the post on X, thanking Kovac for his contributions to the company and saying it had been an ‘honor’ to work with him."The departure raises questions about Tesla's ability to continue developing, manufacturing, and delivering the Optimus robots, a project Musk has touted as potentially generating
"north of $10 trillion in revenue" and becoming Tesla's biggest product ever.
"Kovac’s departure raises questions over the future direction of Optimus, and whether Tesla will successfully be able to develop, manufacture, and deliver the humanoid robots."The stock plunge, the largest single-day drop in Tesla's history, reflects investor concerns amid the leadership shakeup and Musk's public controversies.
"Not long after Elon Musk and President Donald Trump’s very-public social media spat led Tesla shares to take their greatest single-day drop ever on Thursday—erasing $152 billion off its market cap."As Tesla navigates this turbulent period, the future of Optimus remains uncertain, with industry watchers closely monitoring the company's next moves.
