In July 2026, Bloomberg's read of Alphabet's Q2 filing put a number on the quietest compounding machine in tech. Some $124.3 billion of private company investments, driven primarily by one name. Around the same season, the rest of the portfolio kept marking itself up. Waymo closed a $16 billion round at a $126 billion valuation with Alphabet as majority investor. Stripe tendered employees at $159 billion. Even the supporting cast repriced, with Kalshi crossing $11 billion and Lovable reaching $6.6 billion.
The lesson across all eleven names is concentration paired with patience. Write the early check through GV or CapitalG, fund the winner again at every round, and refuse to sell when the marks multiply. Alphabet never needed control of Stripe or a board seat at Anthropic. It needed entry, endurance, and the balance sheet to keep showing up.
