Microsoft’s stock price has risen so much today that it has passed a $4 trillion market valuation for the first time in its 50-year history. The software maker is the second company to be valued at $4 trillion, after Nvidia reached a market cap of over $4 trillion earlier this month. Microsoft has reached this milestone thanks to better-than-expected earnings, and the company reporting its Azure revenue for the first time. Microsoft’s share price is up around 4 percent today, helping it maintain its $4 trillion market valuation. Microsoft has spent more than a decade building up its Azure cloud business, which is ahead of Google’s in revenue but still second place to Amazon Web Services.
