As investors worry about large spending, illusive artificial intelligence revenue, and competition from cheaper AI models from China, Microsoft forecasted diminishing growth in its cloud computing wing, sending its shares down 4.5 percent in after-hours trading.

Wall Street was similarly disappointed by Azure's fiscal second-quarter performance. Investors expect greater results from the hundreds of billions of dollars that Wall Street giants have been investing to create AI data centers and integrate the cutting-edge technology into their products, even though the company has surpassed quarterly total sales estimates.

A price war has been sparked by Chinese competitors' recent claims that they can create rival AI technologies more cheaply than US competitors. Microsoft and its Big Tech competitors have been trying to test Wall Street's patience for over a year by spending enormous sums of money in an attempt to make AI profits that haven't yet pleased investors.

The Azure division of Microsoft reported a 31 percent increase in sales during the quarter, falling short of the 31.8 percent Visible Alpha forecast. According to data from Visible Alpha, Microsoft's capital expenditures totaled $22.6 billion, which was more than the $20.95 billion analysts had predicted.

Concerns about fierce competition that would drive top US AI companies to lower their rates have been raised by DeepSeek's explosive growth over the last three weeks.

During this week, Microsoft said that it has expanded its Azure offerings to include DeepSeek, the popular Chinese AI model. According to Microsoft, AI accounted for 13 percentage points of Azure's growth in the second quarter of its fiscal year, up from 12 percentage points the year before.

In general, Microsoft continues to be seen by investors as a top AI wager. Over the past year, its stock has increased by roughly eight percent, lagging only Alphabet's 29 percent boom and Amazon's 50 percent explosion. According to LSEG, it is currently trading at roughly 32 times projected profits, which is marginally higher than its five-year average of 30.

Additionally, Microsoft reported a 67 percent increase in commercial bookings, a metric used to quantify new agreements with major clients.
