Microsoft overtook Apple as the most profitable company at the end of last Friday’s trading session in the US.

As reported by CNBC, Microsoft’s lead came as a result of an event that took place in San Francisco where the company spoke about artificial intelligence, highlighting an increase of traffic on GitHub which Microsoft acquired in 2018 for $7.5 billion.

Analysts from investment banking company Piper Sandler noted they were “encouraged by the momentum around the most mature AI products.”

Microsoft’s shares increased 3% to $2.89 trillion by the end of the day, while Apple’s dropped by the same amount lowering its valuation to $2.87 trillion.

AI is a core part of Microsoft’s overall strategy. Last month, the company was accused of using AI to promote indie games.
