Senator Markey Demands Contracts and Technical Details on TikTok US Spin-Off

He says the January divestiture may allow ByteDance influence over the app’s recommendation algorithm and has given TikTok US and Oracle until June 18 to respond.

Overview

  • Sen. Ed Markey on Friday sent formal letters to TikTok US and Oracle requesting copies of key contracts and technical explanations, and set a June 18 deadline for responses.
  • The January deal transferred control of US user data and most US operations to a joint venture half-owned by a consortium led by Oracle, Silver Lake and MGX while ByteDance retained a 19.9 percent stake and existing ByteDance investors hold just over 30 percent.
  • The joint venture says it will retrain the app’s recommendation algorithm on US user data and place US data under Oracle oversight, but it also said ByteDance will continue to manage e-commerce, advertising and marketing and will license the algorithm prior to retraining.
  • Markey questioned whether contractual safeguards and source-code review can reliably stop covert manipulation, specifically warning that retained ByteDance roles and pre-retraining licensing may leave the company able to influence recommendations in ways the 2024 law sought to prohibit.
  • The requested documents and technical details could lead to further congressional oversight, hearings or legal scrutiny and will shape whether regulators conclude the spin-off meets the law’s requirement to sever algorithmic cooperation with ByteDance.
