On September 17, Tesla Motors rose 3.59% in regular trading, trading at $364.46/share, with turnover of $2.119 billion. The stock was buoyed by a confluence of positive catalysts, headlined by a landmark Optimus robot mass production milestone.

On the news front, Tesla recently placed approximately 5,000 Optimus humanoid robot orders with suppliers, marking its first thousand-level mass production order following earlier trial batches of several hundred units. A Tesla team arrived in Ningbo on September 16 and launched a new round of supply chain factory audits on September 17, specifically targeting mass production readiness for its robot business. The robots are planned for deployment across Tesla Gigafactories worldwide.

Meanwhile, the Cybercab autonomous vehicle kicked off its first-ever national tour in China, with static displays in Beijing and Shanghai showcasing the steering-wheel-free, pedal-free production vehicle. Tesla also expanded its Semi charging infrastructure through a partnership with Forum Mobility in California, adding 30 megawatts of capacity.

The broader market environment was also supportive, as the Fed's 25-basis-point rate hike to 3.75%-4.00% landed in line with expectations, lifting tech stocks broadly in a relief rally.
