Microsoft announced the launch of its first investment‑grade bond offering in the United States in more than nine years. The company is targeting a minimum raise of $25 billion to fund artificial‑intelligence infrastructure. Bloomberg reported that the final issue size will be determined by market demand. Investors’ appetite for the securities will indicate the level of interest in corporate debt tied to AI projects. The proceeds are expected to support data‑center expansion and related technology investments. The offering marks a return to the U.S. bond market for the tech giant after a long hiatus.
