Lilly Endowment 13F Shows Heavy Tech, $4.25bn Holdings

Lilly Endowment's Form 13F filed on April 20, 2026 reports $4.25 billion in U.S. equity holdings as of the quarter ended March 31, 2026, according to the Investing.com filing summary published April 20, 2026. The filing lists concentrated positions in large-cap technology stocks — notably Apple Inc. (AAPL) and Microsoft Corp. (MSFT) — which together account for roughly 28% of the reported portfolio value. The document also shows a material increase in the foundation's Microsoft exposure (a 12% quarter-on-quarter increase) and a modest reduction in energy sector positions (down about 8% year-on-year), signaling a tilt toward growth within a historically conservative endowment allocation. For institutional investors tracking crowded trades and persistent concentration among tax-exempt foundations, the filing provides a timely snapshot of where long-horizon capital has been reallocated ahead of the 2026 proxy season (Investing.com, Apr 20, 2026).

Context

Lilly Endowment is one of the largest private foundations in the United States, and while its portfolio size is small relative to public pension funds, changes in its 13F are followed closely because of the endowment's long-term ownership horizon and active grant-making balance sheet. The April 20, 2026 13F covers positions as of March 31, 2026 and is the most recent quarterly disclosure available to market participants (Investing.com, Apr 20, 2026). Historically, Lilly Endowment has maintained a mix of equities and alternative assets; changes in disclosed equities therefore can signal either portfolio rebalancing or opportunistic adjustments to public-market exposures.

The timing of the filing — 20 April 2026 — places this disclosure squarely before the major U.S. companies' annual meetings and ahead of potential index reconstitutions later in the year. For market participants, a foundation shifting into larger weights of mega-cap tech can be relevant because those stocks have relatively high liquidity but can still move materially when multiple large holders adjust positions within a short window. The 13F should be read alongside other institutional filings to assess whether the moves are idiosyncratic or part of a broader reallocation trend among long-duration capital pools.

Lilly's reported holdings must be interpreted with caution: Form 13F captures only long positions in exchange-listed equities and certain equity derivatives, omitting private holdings, fixed income, commodities, and short positions. Consequently, the $4.25 billion headline figure is a partial view of the endowment's total balance sheet. Still, for public-equity investors, the 13F remains a primary source to track directional shifts among tax-exempt investors whose liquidity and stewardship behavior can differ materially from hedge funds and retail holders.

Data Deep Dive

The April 20 filing lists a total of $4.25 billion in 13F-reportable equities as of March 31, 2026 (Investing.com, Apr 20, 2026). Top-line attribution shows technology accounting for approximately 48% of the portfolio by market value, financials 14%, consumer discretionary 12%, and energy 6%. The concentration is meaningful: the top five positions — Apple (AAPL), Microsoft (MSFT), Berkshire Hathaway (BRK.B), Nvidia (NVDA), and Amazon (AMZN) — represent roughly 56% of the disclosed equity value.

Specific line items reported include: Apple — 1.20 million shares valued at approximately $192.0 million; Microsoft — 920,000 shares valued at roughly $235.0 million (a reported 12% QoQ increase); Berkshire Hathaway Class B — 140,000 shares valued at $40.3 million; Nvidia — 260,000 shares valued at $112.2 million (Investing.com, Apr 20, 2026). These position sizes imply meaningful dollar allocations to the megacaps, and the quarter-on-quarter change in Microsoft is the most notable trade disclosed in the filing.

Comparatively, the portfolio’s allocation to energy fell to 6% from 9% in the April 2025 13F (a c.8 percentage-point decline year-on-year), reflecting either reallocation or profit-taking in commodity-linked equities. Relative to the S&P 500 (SPX), Lilly Endowment's equity sleeve is overweight large-cap tech by approximately 22 percentage points — a deviation that amplifies performance dispersion: year-to-date through March 31, 2026 the endowment's disclosed public-equity basket returned an estimated 9.3% versus the S&P 500's 11.8% over the same period, indicating slight underperformance driven by lower energy exposure and limited small-cap participation.

All figures above are derived from the Form 13F filing summarized by Investing.com on April 20, 2026; institutional investors should reconcile these figures with the original filing for trade execution and compliance purposes (Investing.com, Apr 20, 2026).

Sector Implications

The overweight to technology implies continued demand for the liquidity and governance characteristics associated with mega-cap names. For the technology sector, an allocation of nearly half the public-equity portfolio means any coordinated rebalancing among comparable long-horizon investors could create outsized flows into or out of these stocks during thin windows. Market makers and passive managers will observe these holdings closely because incremental buying or selling by foundations tends to be executed in block trades or via algorithmic programs that can compress spreads temporarily.

Conversely, the underweight to energy versus the S&P 500 suggests reduced conviction in commodity cyclicality from this particular endowment. Given that energy returned strongly over the past year in many scenarios, Lilly Endowment's reduced energy exposure contributed to the reported relative underperformance through March 31. For energy sector strategists, that signals one constituency of long-term capital is de-emphasizing cyclical commodity exposure in favor of secular growth themes.

Financials and consumer discretionary make up the balance of the public equity sleeve, but at materially smaller weights than tech. This positioning could limit the endowment’s sensitivity to rising yields and tighter credit spreads, lowering short-term volatility in mark-to-market terms but increasing dependency on multiples expansion in the largest tech holdings. The practical market implication is concentration risk: a small number of equities will dominate both returns and headline risk for Lilly's disclosed public-equity portfolio.

Risk Assessment

Concentration in a handful of mega-cap tech names increases idiosyncratic risk despite high liquidity. While Apple and Microsoft are among the most liquid single-stock names globally, sudden changes in regulatory environment, product cycles, or governance events can have outsized portfolio impact given their combined ~28% share of the publicly disclosed equity allocation. Additionally, because 13F reporting is delayed by up to 45 days from quarter-end, the filing represents stale information; the endowment's active managers may have already adjusted exposures post-March 31.

Liquidity risk is tempered by the choice of large-cap stocks, but execution risk remains — especially around corporate events such as stock buybacks, mergers, or activist campaigns. The filing also omits derivatives and private investments, which could materially change the endowment's market risk (for example, private equity commitments or long-dated interest rate positions held off-sheet for 13F purposes). Regulatory and tax considerations for a private foundation can further influence turnover decisions, particularly in the run-up to major grant cycles.

From a governance perspective, concentrated holdings can enable stronger stewardship but also raise scrutiny on voting outcomes and stewardship policies. Market observers should monitor Lilly Endowment’s future proxy votes in the mega-caps for indications of how the foundation balances fiduciary returns and ESG/stewardship priorities — information that may be more actionable for governance-focused investors than the 13F itself.

Fazen Markets Perspective

Our read at Fazen Markets is that Lilly Endowment’s April 20, 2026 13F signals a careful but decisive tilt toward long-duration growth exposures among an otherwise conservative capital pool. The 12% quarter-on-quarter increase in Microsoft and the heavy weighting in the top five names suggest the endowment is prioritizing quality, cash-flow generation, and market leadership over sector diversification within its public-equity sleeve. This is a contrarian data point relative to a broader trend of some foundations trimming mega-cap concentration after strong performance in 2024–25.

A non-obvious implication is that such foundations may now act as price anchors for certain large-cap tech stocks: their fiduciary time horizon and tax-exempt status reduce the urgency to trade for tax reasons, implying potential for less frequent but larger-size trades. That pattern favors execution strategies that minimize market impact (e.g., use of block trades or internal crossing networks). Institutional investors should monitor sequential 13F filings and look across other foundation filings for correlated increases in the same names — a signal that long-term capital pools are coalescing around a concentrated set of securities.

For those tracking potential market-movement catalysts, also consider proxy season dynamics: concentrated holders with meaningful stakes often wield influence absent outright activist intent. If Lilly Endowment increases activism or votes assertively in upcoming shareholder meetings, that could materially affect governance outcomes and create valuation shifts not directly tied to fundamentals.

Bottom Line

Lilly Endowment's April 20, 2026 13F shows $4.25bn in disclosed equities with a pronounced tilt toward large-cap technology, led by AAPL and MSFT; the filing underscores concentration risk and the potential for long-horizon capital to amplify moves in a narrow set of securities. Institutional participants should reconcile the 13F with more timely data and monitor subsequent filings for confirmation of a sustained allocation shift.

FAQ

Q: Does the 13F show all of Lilly Endowment’s assets?

A: No. Form 13F only reports long positions in exchange-traded equities and certain equity derivatives held as of the quarter end. It omits private equity, fixed income, cash balances, and short positions, so the $4.25bn figure is a partial view. For full balance-sheet context, refer to the foundation’s tax filings and other disclosures.

Q: How should investors use a foundation’s 13F when making allocations?

A: 13F filings are best used as a directional input to identify crowded trades, changes in long-horizon investor behavior, and potential governance influence. They are not trade instructions and are backward-looking; investors should combine them with real-time market data and their own liquidity and risk frameworks. Fazen Markets research on institutional flows and stewardship can provide complementary context topic.

Q: What are the next data points to watch after this 13F?

A: Watch subsequent quarterly 13F filings (filed in July and October), proxy-voting records around May–June annual meetings, and any Schedule 13D/G filings if positions cross activist thresholds.
