TikTok plans to build a second 1 billion euro data centre in Finland, expanding its European infrastructure to localize data, bolster privacy safeguards, and address regulatory scrutiny.

The Lahti site in southern Finland will begin with a 50 MW capacity, with potential expansion to 128 MW as demand grows, and is slated for completion by 2027.

The company and its parent ByteDance have denied government influence and point to prior US regulatory restructuring to address concerns.

Despite the investment, questions remain about ownership, data flows, transparency, and oversight, meaning the new centre helps but does not fully resolve regulatory trust issues.

The move aligns with a broader strategy to reduce cross-border data transfers and improve EU data governance for European users.

The expansion is meant to reassure European regulators and the public about data sovereignty and compliance amid ongoing scrutiny.

ByteDance faces global pressure to improve transparency and security around data storage and access, prompting a shift toward localized storage.

The investment underscores a strategy to address regulatory concerns by keeping European data within the region, in a privacy- and child-safety–driven regulatory climate.

This step follows TikTok's restructuring of U.S. operations, with Oracle taking a majority stake to address potential concerns and avoid restrictions.

Industry-wide trend shows rapid data center growth driven by AI and cloud computing, making regionalized storage important for performance and compliance.

Officials worry about potential Chinese government access to foreign user data and manipulation of recommendations, underscoring regulatory stakes.

The announcement comes amid investigations into data privacy and minors’ impact, including a European Commission assessment criticizing TikTok for not adequately safeguarding vulnerable users.
