On October 27, 2025, Baidu Inc. shares closed at $128.66, up 4.81%, with after-hours trading at $129.09 (+0.33%). The surge is attributed to optimism over Baidu's international robotaxi expansion, highlighted by a new partnership with Switzerland's PostBus and ongoing collaborations with Lyft and Uber, signaling rapid global growth for its Apollo Go unit. Investor sentiment was further boosted by Cathie Wood's ARK Invest purchasing approximately $6.5 million in Baidu shares last week, reflecting growing institutional confidence. Additionally, renewed optimism over a US-China trade deal and strong AI/cloud investments contributed to the rally, with analysts maintaining bullish outlooks.
