Baidu hits fifth revenue drop as AI spending surges, stock sinks

Baidu's fifth consecutive revenue drop reflects the dual pressures facing Chinese tech giants in the AI era. The company's core advertising business—historically its profit engine—is fragmenting: ByteDance and Alibaba have captured share that Baidu once dominated. At the same time, the generative AI race has forced Baidu into a massive capex race to build competitive compute infrastructure, tripling quarterly capital spending to stay in the game. Yet this spending has not yet translated into an AI product (Ernie) that matches the performance of newer open-weight models from Moonshot and DeepSeek, leaving Baidu in a costly catch-up position.

The article notes that Baidu's struggle is not isolated—it reflects "broader anxiety over big AI spenders." However, Bank of America's commentary on Nvidia suggests the market may be mispricing that risk. If large capex commitments are temporary and necessary to establish competitive AI infrastructure, then investors may be overstating the downside for chipmakers and their largest customers. For Baidu, the risk is whether the company can narrow the gap with DeepSeek and Moonshot before ad-revenue erosion becomes irreversible.
