Thomas Gayner Q1 2026 Portfolio Overhaul — Major New Stakes in BRK, GOOG, BN
Markel Group's Thomas Gayner executed a comprehensive portfolio restructuring in Q1 2026, building multi-billion-dollar positions in core holdings including BRK, GOOG, BN, and DE through his latest 13F filing.
- Gayner rebuilt his $7.1B portfolio in Q1 2026 with major new positions in BRK, GOOG, BN, and DE
- The restructuring balances tech growth with defensive real-asset and financial holdings
Thomas Gayner, regarded as a paragon of value investing, essentially rebuilt his $7.1 billion portfolio in Q1 2026. With all top five holdings featuring new purchases—an exceptional disclosure—his long-term investment philosophy and directional conviction are now distinctly apparent.
Top 5 Holdings — Q1 2026 Basis
- BERKSHIRE HATHAWAY INC DEL: $800M (6.7%)
- GOOG: $789M (6.6%)
- BERKSHIRE HATHAWAY INC DEL: $734M (6.1%)
- BN: $529M (4.4%)
- DE: $495M (4.1%)
Q1 2026 Key Trading Moves
The most striking feature of this 13F is the dual Berkshire Hathaway position. Gayner deployed approximately $800 million and $730 million respectively across both Class A and Class B shares, establishing a combined $1.53 billion position as his portfolio's largest anchor. The scenario of a Buffett-style investor doubling down on Buffett's company suggests that amid current market uncertainty, Berkshire Hathaway's defensive appeal—as an aggregated holding of cash equivalents and high-quality operating businesses—is being repriced upward.
- BRK Dual Position — Combined Class A and B new purchases totaling ~$1.53B, establishing 12.8% portfolio weight as largest core holding
- GOOG $789M New Entry — Structural conviction in long-term profitability of AI-driven advertising and cloud ecosystems
- BN and DE Major Additions — Asset management (BN, $529M) and agricultural mechanization (DE, $495M) reinforce real-economy hedge
The balance between mega-cap tech and industrials is equally noteworthy. With $789 million committed to GOOG, Gayner is betting on the long-term dominance of AI-powered advertising, while $529 million in Canadian asset manager BN and $495 million in farm equipment leader DE establish solid ground in financial services and real-asset sectors. When combined with existing positions in AMZN, ADI, AAPL, GS, and V, Gayner's portfolio achieves a fully realized composite value structure evenly distributed across technology, financials, and industrials.
Defense and Growth in Tandem — Gayner's Next Move
This filing—marked by zero full exits and only selective reweighting—demonstrates that Gayner leveraged market volatility as a buying opportunity rather than a short-term risk. The dominant BRK weighting serves as a downside buffer, while the tech lineup of GOOG and AMZN functions as the growth engine. With the portfolio compressed to 20 holdings, a concentrated high-conviction strategy is likely to persist in the near term. Changes in BN and DE weightings are poised to become key barometers for assessing macro outlook.
Frequently Asked Questions
Why did Thomas Gayner split Berkshire Hathaway into two separate positions?
Berkshire Hathaway trades as both Class A (BRK.A) and Class B (BRK.B) shares, which are reported as separate line items in 13F filings. By investing in both classes, Gayner leverages liquidity differences while establishing a combined weighting as his portfolio's largest anchor position.
What was the rationale behind the major BN (Brookfield Corporation) stake?
BN is a Toronto-based alternative investment and infrastructure asset management giant. Despite interest rate uncertainty, its real-asset-backed stable cash flow generation aligns with Gayner's long-term value philosophy, offering both growth and defensive characteristics in a single holding.
