Trump hails TikTok deal 

President Trump said Tuesday his administration has struck a deal with China to keep TikTok running in the US, though key details remain unsettled. Beijing has suggested that the platform’s algorithm, which drives its video feed, would stay under Chinese control even if US ownership changes.

Speaking to reporters, Trump said: “We have a deal on TikTok ... We have a group of very big companies that want to buy it.”

Under the reported terms, TikTok’s US assets would transfer from ByteDance to new American owners. The agreement, if finalised, would end months of uncertainty ahead of a government deadline for the app to sell or shut down in the US.

Amazon expands ad integration with SiriusXM

Amazon has expanded its programmatic integration with SiriusXM, giving advertisers more ways to buy audio inventory through its DSP. The update introduces programmatic guaranteed deals and allows users to transact via private marketplaces.

SiriusXM’s first-party data  will also be uploaded to Amazon Publisher Cloud. This update will make it easier for listeners to be attributed to Amazon sales. It also broadens the reach of Amazon’s AI-driven ad products across streaming audio.

Director of the Amazon DSP product, Meredith Goldman, told AdExchanger the update positions Amazon DSP as a full-funnel platform that helps buyers reach consumers at every stage of their journey.
