Microsoft (MS) is showing a sharp upward trend in early trading on the 30th (local time) after announcing quarterly earnings that exceeded market expectations.

As of 10:48 p.m. Korean time, MS shares are trading at $450.80 on the Nasdaq market, up $60.26 (15.43%) from the previous trading day. Strong buying interest poured in from the opening, reclaiming the $450 level.

The key driver behind this surge is the robust growth of its artificial intelligence (AI) and cloud businesses. In Microsoft's fiscal fourth quarter (April–June) 2026 earnings announcement, the company posted revenue of $90 billion. This represents an 18% increase from the same period last year, easily surpassing the $87.62 billion forecast compiled by market research firm London Stock Exchange Group (LSEG).

In particular, the expansion of AI services and the cloud platform Azure are credited with driving the earnings improvement.

These strong results are expected to improve investor sentiment across large-cap tech stocks broadly. Following Microsoft's earnings release, investors are closely watching whether other mega-cap tech companies' earnings and AI business growth momentum will continue.
