Buffett Bought the NYT While Thiel Sold Everything — Dissecting 4 Wall Street Masters' Latest Portfolios
Warren Buffett, Stanley Druckenmiller, Bill Ackman, Peter Thiel. A deep dive into the major portfolio shifts of four Wall Street legends, based on the latest SEC 13F filings.
Q4 2025 13F Filings — Major Portfolio Pivots from Wall Street's Elite
Drawing on the most recently disclosed 13F filings (quarterly institutional holdings disclosures filed with the SEC, Q4 2025), we fact-check and contextualize the latest portfolio moves from Wall Street's top investors.
1. Warren Buffett (Berkshire Hathaway)
Fact Check: Confirmed — Berkshire initiated a new position in The New York Times, added to Domino's Pizza, and built out positions in Chubb and Chevron, while significantly trimming its stake in Amazon.
Deep Dive: Wall Street has taken particular interest in Buffett's moves into The New York Times and Domino's Pizza. Both companies boast powerful brand moats and dependable cash generation — one through a subscription-based digital reader model, the other through a proven franchise structure. This is a textbook, modernized Buffett defensive play: selecting businesses with genuine pricing power capable of passing inflation through to consumers, as a hedge against slowing tech-led growth and rising macro uncertainty.
2. Stanley Druckenmiller
Fact Check: Confirmed — Druckenmiller made major new additions to the top of his portfolio, including the Financial Select Sector ETF (XLF), the S&P 500 Equal Weight ETF (RSP), and the Brazil ETF (EWZ). At the same time, he reduced exposure to semiconductors, including TSMC.
Deep Dive: These moves represent a powerful macro-level conviction trade. Buying the equal-weight ETF (RSP) rather than a market-cap-weighted index signals a view that the era dominated by a handful of mega-cap tech names — the Magnificent 7 and their ilk — is fading, and that the broader market rally is set to broaden out. The heavy allocation to financials (XLF) reads as a tactical positioning for improved bank earnings and credit conditions in a persistently elevated rate or inflationary environment.
3. Bill Ackman (Pershing Square)
Fact Check: Confirmed — Ackman initiated a sizeable new position in Meta worth approximately $2 billion and increased his Amazon weighting. However, the framing that he simply "sold Google to buy Meta" is somewhat overstated. Per the 13F filing, Ackman remains a core shareholder in Alphabet (Google), which still accounts for roughly 13% of his portfolio.
Deep Dive: Ackman's portfolio now has Uber, Amazon, Alphabet, and Meta collectively representing approximately 55% of total assets. His thesis is clearly not centered on AI hardware names like NVDA — rather, he is making a concentrated bet on AI application and B2C platform businesses that can translate vast user data and cloud infrastructure into real, monetizable earnings.
4. Peter Thiel (Thiel Macro)
Fact Check: Confirmed — Peter Thiel has been making highly aggressive, tactical portfolio moves, including dramatically liquidating positions in a short timeframe. In the prior quarter, he exited NVDA and Tesla entirely, rotated into Microsoft and Apple, then proceeded to liquidate those as well.
Deep Dive: It would be a mistake to read the wholesale sale of large-cap tech as a bearish call on AI as an industry. Given Thiel's deep expertise in early-stage private technology investing in Silicon Valley, the more compelling interpretation is that he views current valuations across mainstream big tech as stretched. The prevailing view on Wall Street is that he is building up a significant cash war chest — positioning for the next wave of major AI and space company IPOs, or for new private investment opportunities before they reach public markets.
Summary
Across the Q4 2025 13F filings, a common thread emerges: Wall Street's sharpest minds are rotating capital away from concentrated AI hardware bets — most notably NVDA — and repositioning into their respective areas of core competency.
Warren Buffett — Reliable cash flows as a hedge against uncertainty
Stanley Druckenmiller — A comeback for non-mega-cap stocks, financials, and emerging markets
Bill Ackman — Platform monopolies that convert AI technology into earnings
Peter Thiel — Bypassing crowded public equities in favor of private markets and the IPO pipeline
