1. Elon Musk sued by SEC for allegedly failing to disclose growing Twitter stake

• Musk delayed 11 days in reporting his 5%+ Twitter stake in 2022, the SEC said.

• The delay allegedly helped Musk to boost stake at a discounted price.

• Musk underpaid $150M+ for his Twitter stake, per the SEC.

• This lawsuit comes in Gary Gensler’s final week as SEC chief, who’s departing on Jan. 20.

• Unless SCOTUS intervenes to block the ban.

• “Planning for various scenarios,” TikTok reportedly said in an internal memo.

• A pop-up message would be shown to existing TikTok users after the shutdown.

• Option to download data would be given to users.

• Complete turn off is not required by the law passed in 2024 to ban TikTok, suggesting that TikTok is doing this to create a public uproar in its favor.
