Ultra-Wealthy Investors Pile Into Alphabet in Rare Consensus

In Q2 2026 13F filings, Berkshire Hathaway and a cadre of famed investors—Stanley Druckenmiller, Seth Klarman, David Tepper, and Dan Loeb—simultaneously expanded Alphabet (GOOGL/GOOG) positions, with Berkshire adding about 0.93% of the company across GOOG/GOOGL holdings and others opening or increasing stakes. The moves come as Alphabet posted solid earnings and cloud growth, underpinned by AI initiatives, yet reported negative free cash flow and rising debt, highlighting a nuanced backdrop for the stock’s valuation (roughly 17x trailing earnings). The cluster of bets underscores a rare billionaire consensus on Alphabet’s long‑term AI and cloud potential, even as 13F data represent snapshots from June 30, 2026.

Buffett’s Berkshire boosts Alphabet stake by $17B, elevating it to the portfolio’s third-largest holding

Berkshire Hathaway added about $17 billion of Alphabet stock in Q2, lifting Alphabet to roughly $36.6 billion and making it Berkshire’s third-largest equity position; about 60% of the new Alphabet shares came from a $10 billion private placement with the rest bought on the open market. Berkshire also boosted its Delta Air Lines stake by ~44% to 57.3 million shares (~$5.1 billion) and increased other bets (Macy’s, Lennar) while trimming Ally Financial, Capital One, and Bank of America. The portfolio remains cash-rich with significant buybacks ($4.5 billion in Q2). Michael Burry criticized Buffett’s successor’s use of cash, though Buffett remains focused on waiting for “fat pitches.”

Thousands Still Mirror a Troubled AI Investor’s Trades on Autopilot

Autopilot has more than 5,000 investors continuing to copy Leopold Aschenbrenner’s disclosed stock holdings, with about $28 million still invested after withdrawals and roughly $32 million total since March. The platform tracks 13F disclosures and estimates option exposure, avoids leverage and shorting, and has yielded about 53% since launch but was down over 30% in July. AI‑infrastructure plays such as Nebius, CoreWeave, and Bloom Energy dominate the portfolio. Autopilot plans to keep copying Aschenbrenner’s trades as long as they remain public and may adapt if notable investments (like Anthropic) go public.
