Alphabet Inc. (GOOG) shares slipped Friday after the company made a curious strategic move: it pulled its European Union antitrust complaint against Microsoft Corp's (MSFT) cloud business. The timing is interesting—this came just days after EU regulators kicked off a much broader investigation into the cloud computing sector.

Why Drop the Complaint Now?

Google withdrew its complaint roughly a week after EU officials opened an investigation into whether Microsoft should face tougher regulations designed to curb its dominance in cloud computing. According to the Wall Street Journal, Google's withdrawal is directly connected to the European Commission's investigations into whether Microsoft's Azure and Amazon Web Services need to comply with the Digital Markets Act, the EU's sweeping digital economy law.

The European Commission is examining whether certain segments of the cloud sector are reinforcing the market power of Azure and AWS. These probes are expected to conclude within a year and could result in both platforms being labeled as "gatekeepers" under the Digital Markets Act. That designation would force them to make it easier for competitors to operate and give users more flexibility in their choices.

A Silver Lining for Alphabet's Cloud Business

Earlier this week, Alphabet shares actually climbed after reports surfaced that Meta Platforms Inc (META) is considering using Google's custom Tensor Processing Units (TPUs) to handle its AI workloads.

The chips, available through Google Cloud, could be rented by Meta as early as next year, with potential spending climbing into the billions by 2027 and beyond. The prospect of such a deal highlights Google's growing influence in the AI infrastructure space and gave investors fresh confidence in its cloud operations.

GOOG Price Action: Alphabet shares were down 0.59% at $318.38 at the time of publication on Friday. The stock is approaching its 52-week high of $328.67, according to market data.
