Here's your morning TNB Tech Minute for Thursday, July 31st. I'm Adriana Aspuru for the Wall Street Journal.

Microsoft has become the second company to reach a $4 trillion market capitalization.

Nvidia hit the $4 trillion mark earlier this month.

Microsoft's success has been driven by growth in its cloud computing services. Annual revenue for

Microsoft's Azure cloud business topped $75 billion. That's a 34% increase and was fueled by

high demand for its AI offerings. The company's CEO Satya Nadella said cloud and AI are the

driving forces behind business transformation across all sectors.

Elsewhere, the South Asian ride hailing and delivery giant Grab is leaning into driverless technology to expand in the region.

The company posted four straight quarters of net profit for the first time, and said its artificial intelligence

strategy has helped it keep costs down and boost earnings. Grab is working closely with the Singapore

government on self-driving vehicles, but the company's chief financial officer said that a high

bar on safety protocols and training drivers means that it'll take time. And finally, Samsung Electronics said it expects earnings to regain momentum on AI-fueled demand

for technology products later this year.

This comes after Samsung's semiconductor earnings declined for the fourth consecutive quarter,

impacted by U.S. export restrictions to China and delayed sales of advanced

high bandwidth memory products to NVIDIA. Stick around because Apple and Amazon will report

earnings after the bell. That's your TMB Tech Minute. Join us again this afternoon for more.
