Oracle, which has maintained steady growth with databases and enterprise software, has made its biggest bet since its founding by issuing $25 billion in corporate bonds in February this year, following $18 billion in September last year, to invest in artificial intelligence data centers. Oracle said it raised funds "to build additional infrastructure capacity to meet the contracted demand of cloud infrastructure customers such as AMD, Meta, Nvidia, OpenAI, TikTok, and xAI." International credit rating agency S&P on the 9th downgraded Oracle's credit rating one notch to BBB- from BBB, concerned that a company with high profitability and stable cash generation is shifting to the AI data center sector, making its financial structure more sensitive to investment and business cycles. Oracle shares, which hit an all-time high of $328.33 intraday in September last year, turned downward after the $18 billion bond issuance, sliding to $136.48 on Feb. 5 this year. In results for the fourth quarter of fiscal year 2026 released on the 10th of last month, revenue came in at $19.2 billion and adjusted operating profit at $8.6 billion, up 21% and 22% from a year earlier, beating market expectations, yet the stock fell about 10% in after-hours trading as cloud revenue slightly missed market expectations.
