The breakup of one of the world’s biggest and most consequential monopolies, Google, has been brought up as the US Department of Justice pushes forward with a major antitrust case. Regulators claim Google’s dominance over search and advertising limits competition.

Investors are cautious but not alarmed for now. The tech giant's future remains uncertain, with its market power being in the cross hairs of regulators.
