Roblox (RBLX) shares fell sharply Tuesday following reports of a significant insider sale. The stock traded down about 6% on trading volume that was significantly below average.
Director Anthony P. Lee sold 59,000 shares, valued at roughly $4.72 million. This transaction reduced his total stake in the company by a substantial 18.66%.
The decline occurred despite a positive announcement from the company at CES 2026. Roblox revealed an expansion of its advertising platform.
The company introduced new immersive ad formats and partnerships aimed at brands targeting Gen Z and Gen Alpha users. However, the news of the insider sale overshadowed this development, causing the stock to close lower for the day.
