These Are the 3 Biggest Stocks in Alphabet's Secret Portfolio

"Google parent Alphabet ( NASDAQ:GOOG )( NASDAQ:GOOGL ) is often seen as a core tech giant focused on search, advertising, and cloud computing. Yet beneath its main operations lies a quieter side: a venture arm that invests in promising companies in areas like space tech, geospatial data, and semiconductors. These bets target innovations adjacent to Alphabet's ecosystem, such as enhanced connectivity for Android devices, Earth observation for AI-driven mapping in Google Earth, and efficient chip designs for data centers powering Google Cloud."

"Through GV (formerly Google Ventures) and CapitalG, Alphabet manages a portfolio of about 37 public stocks valued at $2.5 billion to $3 billion as of late 2025. The three largest positions - AST SpaceMobile ( NASDAQ:ASTS ), Planet Labs ( ), and Arm Holdings ( ) - highlight its strategy of backing high-growth plays in satellite networks, imaging analytics, and artificial intelligence (AI) hardware."

"AST SpaceMobile (ASTS) AST SpaceMobile tops Alphabet's portfolio with a stake worth approximately $459 million at current prices, representing 18% of its equity holdings. The company aims to build a satellite-based cellular network that connects unmodified smartphones directly from space, eliminating dead zones in remote areas. Alphabet's interest stems from synergies with Android, with plans to enable seamless SpaceMobile connectivity on billions of devices worldwide. This aligns with Alphabet's push for ubiquitous access to its services, like Maps and YouTube, in underserved markets."
