Sen. Ed Markey on May 29 pressed TikTok's U.S. joint venture and Oracle to answer for how the data of Americans who use Tik Tok will be protected, and for how the app's recommendation system will be kept from foreign manipulation.
The Massachusetts Democrat's request lands as more than 200 million Americans still use the app and its new ownership structure is moving into place. In January, ByteDance finalized a deal creating a majority American-owned joint venture meant to secure U.S. data and avoid a U.S. ban on TikTok, with Oracle named as one of the venture's three managing investors.
TikTok said in January that the venture would retrain, test and update the app's recommendation algorithm on U.S. user data and keep that system secured in Oracle's U.S. cloud. That promise is now the point of Markey's scrutiny. He is not challenging the idea that a domestic structure can be built; he is asking whether the safeguards around it are strong enough to withstand pressure from abroad.
The gap matters because the arrangement was designed to answer the same fear Markey is now raising: that control over data and the algorithm could still leave room for outside influence, even if the company is American-owned on paper. Oracle's role gives the plan a domestic anchor, but it also puts one of TikTok USDS JV's managing investors squarely in the middle of the argument over whether the system can truly be isolated from foreign reach.
What comes next is a test of the deal's credibility. TikTok USDS JV and Oracle are expected to respond to Markey's questions, and those answers will show whether the new structure can satisfy lawmakers or whether the security concerns that drove the January deal are still unresolved.
