The recent departure of Linda Yaccarino as CEO of X coincides with a 10% decline in its daily active user base, now at 132 million, according to Sensor Tower. Meanwhile, competitor Threads reported a 127.8% year-over-year growth, reaching 115.1 million daily users. Although X maintains stronger user engagement—with an average usage time of 31 minutes versus Threads' 8—it faces escalating competition as Threads enhances its advertising features, drawing closer to X's user base.
