Global Market: Japan’s Nikkei plunges nearly 5% as AI stocks tumble on CoreWeave debt concerns

The Japanese benchmark indexes dropped sharply on Tuesday, with the Nikkei 225 sliding close to 5% and the broader Topix down about 2.5%. The fall was led by shares of companies tied to artificial‑intelligence hardware and services.
The sell‑off was sparked by worries that US cloud‑computing provider CoreWeave may face liquidity strain, raising doubts about the financing of AI projects. At the same time, hotter‑than‑expected US inflation revived concerns that central banks could keep interest rates higher for longer, which typically hurts growth‑oriented tech stocks.
Investors will be watching any updates on CoreWeave’s debt situation, upcoming US inflation and policy data, and earnings reports from Japan’s AI‑related chip makers such as Advantest and Tokyo Electron. A reversal in sentiment could depend on clearer guidance on financing and monetary‑policy outlook.
