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

The Gates Foundation’s equity portfolio is concentrated, with Berkshire Hathaway the largest holding at 24.6%, followed by Caterpillar at 18.3%, WM at 17.7%, and Canadian National Railway at 17.4%. The article highlights solid fundamentals and reasonable valuations for Berkshire and WM, while Caterpillar’s stock has rallied on data-center demand but now trades at about 40x earnings, making it more expensive. Canadian National is benefiting from capital discipline and buybacks, with capex set to fall 15% and authorization to repurchase up to 24 million shares.

Analysis

The portfolio composition is less a reflection of ‘Gates-style growth’ than a concentrated bet on durable pricing power plus capex visibility. That matters because the common thread across BRK.B, WM, CNI, and CAT is not sector exposure but embedded optionality to pass through inflation while preserving margins; the market is rewarding that durability, but in CAT’s case the multiple has already discounted a multi-year AI/data-center supercycle before the earnings base fully catches up.

Second-order, the biggest hidden beneficiary is not necessarily the obvious names but the ecosystem around data-center and industrial capex. CAT’s order flow likely supports power equipment, grid infrastructure, and select electrical component suppliers, while simultaneously pulling labor and equipment away from traditional construction uses; that can subtly tighten pricing in adjacent end markets even if headline construction demand looks flat. By contrast, CNI’s current setup suggests a more tactical rather than structural rerating: if freight volumes stabilize, the combination of lower capex and buybacks can drive EPS faster than revenue for 4–6 quarters, but tariff sensitivity leaves the path vulnerable to a single policy reversal.

The consensus risk is that investors are extrapolating ‘quality at any price’ into names that are qualitatively different on duration. WM and CNI still look like compounders with recession resilience, but CAT is behaving like a cyclical growth proxy priced as a secular winner; that asymmetry argues for respecting earnings downside if data-center demand normalizes or if order timing slips. BRK.B remains the cleanest defensive proxy, but its upside is increasingly tied to capital deployment discipline at the subsidiary level, so the market is really underwriting execution by Greg Abel rather than a simple conglomerate discount closure.

Key Decisions for Investors

• Long BRK.B vs. short a basket of high-multiple industrial cyclicals for 6-12 months: use BRK.B as the quality anchor and fade names where multiple expansion has outrun cash-flow visibility; target modest upside with lower drawdown if growth cools.
• Reduce or avoid initiating fresh longs in CAT at current levels; if holding, consider a collar over the next 1-2 quarters because the stock is priced for sustained data-center acceleration and is vulnerable to any order-delay headline or macro slowdown.
• Add WM on 6-18 month weakness, not strength: the thesis is margin compounding and vertical integration, so entry is better on any post-earnings pullback; downside is limited by monopoly-like landfill economics, upside is steady mid-single-digit CAGR plus multiple support.
• Pair long CNI / short a more expensive rail or trucking proxy for 6-12 months: CNI’s capex discipline and buyback execution can outgrow the sector on EPS even if top-line is muted; thesis breaks if tariffs or industrial recession extend beyond two quarters.
• Watch for a rotation into GOOGL as an indirect capex beneficiary through cloud/data-center demand; if CAT and power-generation names keep inferring robust AI infrastructure buildout, GOOGL offers better relative value with less direct operating leverage.
