X CEO signals ad boycott is over. External data paints a different picture.

When X CEO Linda Yaccarino took the stage as a keynote speaker at CES 2025, she revealed that "90 percent of the advertisers" who boycotted X over brand safety concerns since Elon Musk's 2022 Twitter acquisition "are back on X."

Yaccarino did not go into any further detail to back up the data point, and X did not immediately respond to Ars' request to comment.

But Yaccarino's statistic seemed to bolster claims that X had made since Donald Trump's re-election that advertisers were flocking back to the platform, with some outlets reporting that brands hoped to win Musk's favor in light of his perceived influence over Trump by increasing spending on X.

However, it remains hard to gauge how impactful this seemingly significant number of advertisers returning will be in terms of spiking X's value, which fell by as much as 72 percent after Musk's Twitter takeover. And X's internal data doesn't seem to completely sync up with data from marketing intelligence firm Sensor Tower, suggesting that more context may be needed to understand if X's financial woes may potentially be easing up in 2025.

Before the presidential election, Sensor Tower previously told Ars that "72 out of the top 100 spending US advertisers" on Twitter/X from October 2022 had "ceased spending on the platform as of September 2024." This was up from 50 advertisers who had stopped spending on Twitter/X in October 2023, about a year after Musk's acquisition, suggesting that the boycott had seemingly only gotten worse.
