2023 Predictions on the Big Tech Focus of the Antitrust Agencies from Katrin Schallenberg
Katrin Schallenberg, Partner, discusses her top predictions for the big tech focus of the antitrust agencies in 2023. Global tech companies will have to navigate an increasingly complex environment around the world which will require them to spend more resources engaging with the regulators across jurisdictions. EU, UK, US and China are some of the regions where antitrust agencies will be most active but other countries are also developing new regulations. Katrin expects to see more cooperation between authorities in different countries beyond 2023.
