An Act Banning TikTok in Montana (SB 419, 2023)

SB 419 would have barred TikTok from operating in Montana from January 1, 2024, citing user-data privacy and national-security concerns about Chinese control. A federal court preliminarily enjoined it on November 30, 2023, before it took effect. Its own section 4 voids the Act if TikTok is sold to a company not incorporated in a foreign-adversary country; the parties agreed that happened with the 2025-2026 TikTok divestiture, and the case was dismissed on February 23, 2026, with the Ninth Circuit appeal closed by mandate on September 23, 2026.
