Billionaire Bill Gates Has 78% of His Foundation's $34 Billion Portfolio Invested in 4 Fantastic Stocks

The article highlights the Gates Foundation Trust’s concentrated equity portfolio, with Berkshire Hathaway still the largest holding at 24.6%, followed by Caterpillar at 18.3%, WM at 17.7%, and Canadian National Railway at 17.4%. Caterpillar’s rise to the second-largest position was driven by data-center-related demand, while Canadian National is benefiting from reduced capital spending and buybacks. Overall tone is constructive on these businesses, but the piece is largely portfolio commentary rather than a new market-moving catalyst.

Analysis

The portfolio is effectively a high-quality barbell on cash conversion and moats, but the market is starting to re-rate the “boring compounders” differently: industrial exposure is being pulled upward by AI infrastructure spend, while the railroad and waste names are increasingly priced as bond proxies rather than operating businesses. That creates a subtle dispersion opportunity: the same thesis that supports CAT’s power-generation upside also supports its suppliers and less-levered peers, but CAT’s multiple has run ahead of its near-term earnings sensitivity, leaving it more vulnerable to any slowdown in data-center capex or order timing slippage.

Berkshire remains the cleanest expression of the trust’s preference for underwriting quality at a discount, but the post-transition setup is less about Buffett-style capital allocation and more about whether Greg Abel can maintain the conglomerate’s insurance float advantage while deploying excess capital without diluting returns. The key second-order effect is that Berkshire’s embedded cash plus operating earnings now create a self-funding buyback engine; if equity markets weaken, BRK.B becomes even more attractive relative to the market because it can repurchase stock aggressively while peers are forced to preserve balance sheet flexibility.

WM and CNI are both being valued as low-beta compounding vehicles, yet their real upside depends on volume/mix and capital discipline rather than headline growth. For WM, the hidden catalyst is margin expansion from healthcare integration and route density, which could surprise on free cash flow even if revenue stays subdued; for CNI, the market is underappreciating how capex restraint can mechanically lift FCF and support a larger repurchase cadence over the next 4-6 quarters. The contrarian risk is that both names can disappoint if investors rotate back into faster growth—then their premium stability valuations compress without a corresponding earnings upgrade.

Key Decisions for Investors

• Long BRK.B on 6-12 month horizon: best risk-adjusted defensive compounder; add on any 3-5% market pullback, with downside cushioned by buybacks and conglomerate liquidity.
• Reduce/short CAT into strength over the next 1-3 months: price has outrun forward earnings revision risk; use a call spread or outright short versus XLI as a hedge if data-center capex growth slows.
• Pair long WM / short a small-cap waste operator basket for 6-9 months: WM’s scale and landfill network should keep margin expansion intact while smaller peers face higher integration and route-density pressure.
• Long CNI vs. short a higher-multiple railroad or trucking proxy for 6-12 months: CNI’s capex pullback and buyback authorization improve FCF yield; upside comes from multiple compression elsewhere rather than heroic volume growth.
• If seeking a less crowded industrial exposure, rotate from CAT into suppliers with cleaner valuation and less execution risk; CAT only becomes compelling again if it derates 15-20% or management raises 2025-2026 organic growth guidance materially.
