Amazon Faces Potential FTC Fines While Citadel Cuts Position and SpaceX Tops $2.9T Valuation
AMZN•An FTC antitrust probe into Amazon’s advertising practices could trigger fines of several billion dollars, threatening its high-margin ad revenue. Citadel Advisors cut its Amazon stake in Q1 as SpaceX’s shares soared to a $2.9 trillion valuation, briefly surpassing Amazon’s market cap.
1. FTC Advertising Probe Exposes Amazon to Multibillion-Dollar Fines
The Federal Trade Commission is scrutinizing Amazon’s digital advertising unit for potential anticompetitive practices, with initial estimates suggesting penalties could reach several billion dollars. This probe adds regulatory risk to the company’s high-margin ad revenue stream and could force operational changes to its platform.
2. Citadel Advisors Trims Amazon Position in Q1
In its latest 13F filing, Ken Griffin’s Citadel Advisors reduced its holdings in Amazon while boosting its stake in Intuitive Surgical by 30.3%. The shift reflects a broader reallocation of capital away from mega-cap tech toward healthcare names perceived to offer stronger valuations.
3. SpaceX Valuation Briefly Overtakes Amazon at $2.9 Trillion
SpaceX shares jumped 20% on early trading and surged further upon the start of options trading and news of its $60 billion stock-financed acquisition of Cursor. The gains propelled SpaceX’s market value to $2.9 trillion, momentarily surpassing Amazon’s market cap and highlighting investor enthusiasm for space and AI sectors.
