Alibaba Raises Another HK$80 Billion — Is China CSP's Golden Cycle Just Beginning, or the Eve of a Bubble?

Alibaba's earnings report just proved that China's cloud business is re-accelerating: in the June quarter, AI cloud and computing power revenue grew 45% year-over-year, AI-related product revenue reached 12.376 billion yuan, and the cloud business EBITA margin rose to 12%; days later, the company placed 710 million shares at HK$112.7, raising HK$80 billion, all to be invested in full-stack AI capabilities and infrastructure. Around the same time, Kingsoft Cloud also delivered results showing high AI cloud growth and a positive swing in operating margin. Revenue and profitability improvements have already emerged, but the massive fundraising pushes the question deeper: is China's CSP entering a high-return capex cycle, or heading toward an arms race of continuously declining ROIC?
