On August 21, Tesla Motors rose over 4% in regular trading. Multiple positive catalysts continued to fuel momentum throughout the session.

On the news front, sources revealed that Tesla plans to open its Cybercab autonomous taxi — the company's first vehicle with no steering wheel or pedals — to public trial rides in Austin, Texas by month-end, formally integrating into the local Robotaxi network. This marks a critical milestone in driverless commercialization. Emergency responder training has been completed in the Austin area, and charging infrastructure including 80 wireless chargers is being deployed in a second-phase buildout. Morgan Stanley noted Tesla is deliberately controlling Model Y deliveries to make room for Cybercab deployment.

Additionally, FSD subscription mode launched in South Korea at 150,000 won per month, marking its first entry into Asia. Tesla's China in-car system also completed the rollout of ByteDance's Doubao large language model. Within the Automobile Manufacturers sector, broad-based strength was evident, with Rivian up 4.84%, Stellantis up 3.52%, Ford up 2.64%, General Motors up 2.34%, and Ferrari up 1.41%.
