The $1.5 Million Truce: Elon Musk Settles SEC Lawsuit Over “Hidden” Twitter Stake and Acquisition Gamesmanship

**Executive summary:** Elon Musk reached a settlement with the U.S. SEC over his eleven-day delay in disclosing a greater-than-5% stake in Twitter (now X) during his 2022 acquisition, agreeing to a $1.5 million civil penalty while neither admitting nor denying wrongdoing; the SEC will dismiss the litigation. The SEC alleged the late filing created information asymmetry that allowed Musk to avoid roughly $150 million in acquisition costs and deprived shareholders of material information.
