Microsoft Stock Hits Record High Amid AI Spending Surge

Microsoft shares closed at $543.45 on Tuesday, reaching a record-high share price that caps a four-month market recovery and restores the tech giant’s $4 trillion valuation, The Seattle Times reported.

Maia 300 Chip Deployment Schedule

The record close followed Monday’s announcement regarding the third generation of Microsoft’s custom silicon. The company stated it will begin widely deploying Maia 300 chips to data centers next year, a hardware shift designed to decrease reliance on external suppliers like Nvidia.

Chief Executive Satya Nadella characterized the hardware initiative on the social media platform X as the organization’s largest commitment yet to proprietary silicon. Cloud and artificial intelligence leader Scott Guthrie noted in a corporate blog post that the Maia 300 design is projected to deliver 40% more tokens per megawatt than leading graphics processing units while consuming less electricity.

Fiscal Earnings and Market Rebound

Tuesday’s peak surpassed the previous high of $542.07 set in October 2025. That milestone preceded an eight-month downturn that erased roughly $1 trillion in market capitalization amid investor skepticism regarding capital expenditures for artificial intelligence infrastructure and slower cloud revenue growth.

Comparative Market Performance

Microsoft’s late-year momentum has outpaced broader market benchmarks, with year-to-date gains reaching 15% compared to a 21% rise for the Nasdaq-100 index. The company’s performance currently surpasses the annual gains of cloud competitors Amazon and Alphabet, though it trails Meta’s 17% increase.

Microsoft shares reach record highs after posting strong quarter

Concurrently, the company has recalibrated its software strategy. After addressing consumer complaints regarding early iterations of Copilot within the Windows operating system earlier in the year, Microsoft consolidated consumer features into a dedicated super app in September. Paid Copilot users exceeded 30 million in July, up from 20 million the previous quarter. Hardware updates arrived last week with new Surface personal computers capable of running local artificial intelligence agents rather than relying entirely on cloud processing.
