Investor nervousness surrounding Oracle's financial strategy for its artificial intelligence infrastructure is growing, as indicated by a significant increase in the cost to insure against the company's debt. Reports highlight that traders are increasingly hedging against credit risk, with credit default swaps (CDS) widening. This market reaction stems from concerns over the substantial debt, reportedly around $38 billion, that Oracle is taking on to fund its aggressive expansion in the competitive AI and cloud infrastructure space. This sentiment in the credit markets reflects broader caution among investors, contributing to the stock's significant decline of as much as 37% from its September record high. While Oracle's heavy investment is aimed at capturing a larger share of the AI market, the immediate financial strain is causing unease. The market is now treating Oracle's credit performance as a key indicator for the financial health of the wider AI-infrastructure boom.
