Companies Owned by Bill Gates: Stakes, Investments & Exits

Bill Gates moved from operating control of Microsoft to a portfolio model built around Cascade Investment, personal Microsoft shares and philanthropy. Cascade is the capital-allocation vehicle. It holds public securities, real assets and control investments on Gates's behalf, while the Gates Foundation and its trust pursue charitable objectives under separate governance. This distinction prevents charitable endowment assets from being counted as personal holdings and keeps fund-backed climate companies separate from direct ownership.

Four Seasons Hotels and Resorts is the most significant controlled business visible in the portfolio. Cascade owns 71.25 percent after a $2.21 billion transaction completed in January 2022. Four Seasons operates mainly through management contracts and brand licensing, giving it lower property capital intensity than a hotel owner. Its economics depend on global room demand, fee growth, owner investment, residential and ancillary expansion, and consistent service quality. The brand can compound without buying every property, but reputational failures or owner disputes can impair future contracts.

Microsoft remains a major source of personal wealth, though Gates is neither an executive nor a director. His roughly 103 million personally held shares in 2026 provide liquid public-market exposure to software, cloud computing and artificial intelligence. Cascade's other public positions diversify sector risk but do not create operating control. The portfolio therefore combines one high-quality controlled hospitality platform with liquid minority securities and longer-duration private investments.

We view governance separation as the defining feature. Cascade should maximize risk-adjusted returns for Gates's personal capital; the foundation trust should fund grants and preserve charitable purchasing power; Four Seasons management should serve all shareholders and hotel owners. Transactions or shared advisers can create confusion if those mandates blur. Clear entity-level reporting, disciplined liquidity management and valuation based on cash-flow rights rather than association are essential to assessing the portfolio accurately.

Capital allocation must also account for the scale and timing of charitable commitments. Liquid securities can support grants and taxes, while Four Seasons and private technology positions may require patient holding periods. Cascade therefore adds value through liability-aware portfolio construction, not simply security selection. A strong outcome preserves sufficient liquidity, limits correlated technology exposure and allows controlled businesses to invest through a downturn without forcing sales at weak valuations. The portfolio should also measure currency and travel-cycle exposure because Four Seasons earns across regions while personal and charitable obligations may be concentrated in different currencies.

Gates exercises almost no direct control over the company that made him famous. His roughly 1.39 percent Microsoft stake carries no special governance rights, and he has not held a board seat since resigning in March 2020, a departure later reporting connected to a board investigation into a prior personal relationship with a Microsoft employee. Microsoft's actual ownership and governance today are dominated by institutional index and asset managers such as Vanguard, BlackRock, and State Street, not by its co-founder.

The real seat of Gates' control sits at Cascade Investment, which he wholly owns and which Michael Larson has run day-to-day since the mid-1990s. Most of Cascade's largest public positions, Republic Services, AutoNation, and Deere, are significant enough to make Cascade each company's largest single shareholder, giving Gates meaningful influence without outright control, since none of those stakes clears 50 percent. Four Seasons Hotels and Resorts is the clear exception: Cascade's 71.25 percent stake, reached through a 2021 to 2022 transaction, gives Gates genuine majority control over a company for the first time in his post-Microsoft career.

The Gates Foundation represents a different kind of authority entirely, one that is organizational and philanthropic rather than an ownership stake. As Chairman, Gates has real influence over the foundation's direction and grantmaking priorities, and the 2024 departure of Melinda French Gates as co-chair, following their 2021 divorce, left him as its sole family leader. But the foundation's roughly 89 to 92 billion dollar endowment is not his property in any legal or economic sense once donated; it is governed as an independent charitable trust with its own CEO, Mark Suzman, running day-to-day operations.

Taken together, Gates' control today is best described as concentrated in a private, low-profile investment vehicle most readers have never heard of, almost entirely absent from the public company he co-founded, and organizational rather than financial at the large philanthropic institution that bears his name.

Control is strongest at Four Seasons and weakest in listed minority positions. Cascade can influence Four Seasons through its 71.25 percent vote, but management still depends on hotel owners, employees and minority shareholders. Gates's Microsoft stake conveys economic participation rather than operating authority. We would therefore apply a control premium only where voting rights are paired with practical decision-making power, and we would preserve a governance discount where related personal and charitable entities could be confused.

Gates' investment activity outside Microsoft is substantial and genuinely diversified, running across two distinct vehicles with very different risk profiles. Cascade Investment handles the large, established side of his portfolio: significant, often largest-shareholder stakes in mature public companies like Republic Services, AutoNation, Deere, and Ecolab, plus the outright controlling position in Four Seasons Hotels and Resorts. These are the kind of long-horizon, income-generating positions typical of a family office managing multi-generational wealth rather than chasing short-term returns.

Breakthrough Energy Ventures sits at the opposite end of the risk spectrum. It is worth noting that Gates' personal dollar commitment to Breakthrough Energy specifically has never been publicly itemized, so the fund's scale should be understood as a shared commitment among Gates and a group of co-investing billionaires rather than a purely Gates-funded vehicle.

The farmland holdings, managed through Cascade's Cottonwood Ag Management subsidiary, function as a third, distinct category: a large, illiquid, income-producing real asset rather than an equity investment in an operating company. Gates has described the roughly 242,000 to 275,000 acre position as ordinary financial diversification, and the acreage, while making him the largest private individual farmland owner in the country, remains a small fraction of total U.S. farmland.

What unites these three investment programs is a consistent preference for long-term, professionally managed positions over active personal trading. Whether the asset is a century-old candy company by analogy, a waste management giant, an unproven e-fuels startup, or a few hundred thousand acres of cropland, Gates' capital flows through the same small set of structures rather than a personal, ad hoc investment style.

Climate and frontier-technology investments can produce large social and financial upside, but they require long holding periods and follow-on capital. The proper unit of analysis is the fund or special-purpose vehicle that owns the stake, not Gates's public association with a portfolio company. For Cascade, position sizing should reflect technical risk, commercialization timelines and liquidity. Public equities can fund commitments and grants, while illiquid investments should earn a return premium for duration and uncertainty.

The portfolio's hurdle rates should also reflect mission overlap. A climate investment may advance a policy goal while offering venture-style returns, but the financial vehicle still needs explicit ownership rights, reserves and exit assumptions. Keeping those standards visible prevents philanthropic impact from being used to excuse weak investment governance and prevents short-term market volatility from undermining patient technical development.

Gates has never had a single, discrete exit from Microsoft in the way other founders in this dataset have sold a company outright. Instead, his position has been drawn down continuously since the company's 1986 IPO, through a mix of open-market sales and large block donations to the Gates Foundation Trust, including a substantial 2022 donation that Forbes credits with pushing his personal stake below the 1.3 percent level it had held since 2020. By 2018, Bloomberg he had already sold more than 40 billion dollars of Microsoft stock and collected over 11 billion dollars in dividends since the IPO, a scale of realized value that dwarfs any single transaction covered elsewhere in this profile.

One useful marker of how far that drawdown has gone: Steve Ballmer, Microsoft's former CEO, overtook Gates as the company's largest individual shareholder around May 2014, a full decade before the more recent milestones covered here. Gates' governance exit followed later and more cleanly, with his March 2020 resignation from Microsoft's board ending any formal role at the company entirely.

The Gates Foundation Trust's own Microsoft position tells a separate, cleaner exit story. The Trust had held Microsoft shares continuously since its founding in 2000, began trimming the position in late 2023, sold roughly 65 percent of what remained in the third quarter of 2025, and sold its final 7.7 million shares in the first quarter of 2026, a complete divestment disclosed in May 2026. It is important to keep this separate from Gates' own holdings: the Trust's exit is total, while Gates' personal roughly 1.39 percent stake remains intact and is a different legal position entirely.

Outside Microsoft, there is no comparable exit history to report. Cascade's other major positions, Republic Services, AutoNation, Deere, Ecolab, and Four Seasons, all remain active holdings as of this writing, and Breakthrough Energy Ventures' portfolio companies are similarly still active. Gates' pattern since leaving Microsoft's board has been accumulation and diversification through Cascade, not further exits.

Gates's gradual reduction of Microsoft ownership transformed a concentrated founder position into diversified capital and philanthropy without requiring a corporate sale. That is economically different from an entrepreneur selling control to one buyer. The relevant lesson is staged liquidity: public shares allowed donations and diversification over decades, while retaining exposure to Microsoft's compounding. Four Seasons represents the opposite move, increasing control through a negotiated purchase when a durable brand and fee model justified concentration.
