NextFin News - Turkey’s Competition Authority has formally launched a new investigation into Google’s advertising and billing practices, marking a significant escalation in the country’s multi-year regulatory campaign against the search giant. The probe, announced on April 3, 2026, focuses on allegations that Google has leveraged its dominant market position to impose unfair conditions on advertisers and manipulated billing mechanisms to the detriment of local competitors. This latest move by the Turkish watchdog, known as Rekabet Kurumu, follows a string of previous fines and investigations targeting Google’s Android ecosystem and its Play Store payment rules.
The investigation centers on Google’s "Performance Max" (PMAX) advertising product and its integrated billing systems. Regulators are examining whether the AI-driven automation within PMAX effectively obscures pricing transparency, making it difficult for advertisers to verify the true cost of their campaigns or compare them with rival services. According to a statement from the Turkish Competition Authority, the board will determine if these practices violate Article 6 of Law No. 4054 on the Protection of Competition, which prohibits the abuse of a dominant position. The probe is not merely a local grievance; it mirrors broader global scrutiny from the European Union and the United States regarding "black box" advertising technologies that consolidate data and revenue within a single ecosystem.
Market analysts suggest that Turkey’s aggressive stance is part of a broader strategy to assert digital sovereignty and protect its domestic tech sector. "Turkey has become one of the most proactive jurisdictions in the world when it comes to Big Tech oversight," says Kerem Alkin, an economist who has frequently commented on Turkey’s digital trade policies. Alkin, who generally supports the strengthening of local competition frameworks, notes that while these investigations are legally grounded in antitrust law, they also serve as a signal to multinational corporations that the Turkish market will no longer operate under a laissez-faire digital regime. However, Alkin’s perspective is often viewed by some international investors as aligned with the government’s protectionist leanings, and his views may not represent the consensus among global tech analysts who fear such probes could stifle innovation.
The financial stakes for Google are substantial. Under Turkish law, companies found in violation of competition rules can face fines of up to 10% of their annual turnover. Google has already paid hundreds of millions of dollars in cumulative fines to Turkey over the past decade. Beyond the direct financial impact, the investigation threatens Google’s operational model in the region. If forced to decouple its billing systems or provide deeper transparency into its proprietary advertising algorithms, the company could see a decline in the efficiency and profitability of its Turkish operations. This comes at a time when U.S. President Trump’s administration has expressed varying degrees of support for American tech firms abroad, though the current administration's focus on "reciprocity" in trade may complicate any diplomatic intervention on Google’s behalf.
Critics of the investigation argue that Turkey’s frequent regulatory interventions create an unpredictable business environment. Some legal experts in Istanbul, speaking on condition of anonymity to discuss sensitive regulatory matters, suggest that the Competition Authority’s focus on billing practices might be a proxy for tax disputes. They point out that by framing billing as a competition issue, the government can exert more direct pressure on Google’s revenue flows than through traditional tax audits. This perspective remains a minority view, as most official data suggests the probe is strictly focused on market dominance and the technicalities of digital ad auctions.
The outcome of this probe will likely hinge on Google’s willingness to offer "commitments"—a legal mechanism in Turkey that allows companies to settle investigations by promising specific behavioral changes. In previous cases involving the Play Store and search algorithms, Google has eventually complied with Turkish demands, albeit after lengthy legal battles. As the investigation moves into its discovery phase, the Turkish Competition Authority is expected to solicit testimony from local media agencies and rival ad-tech providers to build its case. The proceedings are expected to last at least six to twelve months, keeping Google’s Turkish operations under a cloud of regulatory uncertainty for the foreseeable future.
