TikTok signed an agreement to spin off parts of its U.S. operations into an independent joint venture after ByteDance agreed last month to divest about 80 percent of its American assets.The new U.S. entity will oversee national security tasks with Oracle, Silver Lake and MGX holding a combined 45 percent stake, affiliates 30 percent, new investors 5 percent and ByteDance just under 20 percent, and the spin-off is expected to close in late January 2026 with ByteDance retaining control of global e-commerce and advertising.
