Italy’s antitrust authority announced Tuesday that it has opened a formal investigation into Apple regarding its compliance with interoperability obligations established under the European Union’s Digital Markets Act.

The Digital Markets Act, which came into force to curb the market power of large technology companies, imposes a series of obligations on designated “gatekeepers” — firms whose platforms play a critical role in connecting businesses and consumers.

Apple is one of several major technology companies designated as a gatekeeper under the legislation.

Focus on Interoperability Requirements

The investigation centers on interoperability rules that require gatekeepers to allow competing services and products to interact more effectively with their platforms and ecosystems.

The DMA aims to prevent dominant technology firms from restricting competition by limiting access to key hardware, software, operating systems, or platform functionalities.

Regulators will likely examine whether Apple has provided sufficient technical access and compatibility to third-party developers, cloud service providers, and competing digital platforms as required under European law.

Growing Regulatory Pressure Across Europe

The Italian investigation represents the latest example of European regulators taking a more aggressive approach toward enforcement of the Digital Markets Act.

Since the law’s implementation, regulators have closely monitored whether major technology companies are complying with requirements involving app stores, messaging interoperability, search services, advertising practices, and cloud infrastructure.

Apple has already faced scrutiny from European authorities regarding App Store policies, browser choices, payment systems, and access to device features.

Potential Implications

If regulators determine that Apple has failed to meet DMA requirements, the company could face corrective measures and potentially significant financial penalties.

Under the Digital Markets Act, violations can result in fines of up to 10% of a company’s global annual revenue, with even higher penalties possible for repeat offenses.

Beyond financial consequences, regulators can require operational changes designed to increase competition and improve access for rival services.

Why It Matters

Cloud services and interoperability have become increasingly important battlegrounds in the technology sector.

Businesses and consumers often become deeply integrated into digital ecosystems, making it difficult and costly to switch providers.

European regulators argue that stronger interoperability requirements can reduce these barriers, encourage innovation, and create more competitive digital markets.

The outcome of Italy’s investigation could provide further guidance on how aggressively EU authorities intend to enforce the Digital Markets Act against large technology companies.

Outlook

The probe is likely to become part of a broader European effort to evaluate compliance among major gatekeepers operating within the region.

Investors and technology companies will be watching closely, as enforcement decisions could influence how digital platforms design their products, manage developer access, and compete within the European market.

For Apple, the investigation adds another layer of regulatory scrutiny at a time when policymakers globally are increasing oversight of large technology ecosystems.
