CalSTRS Q1 2026: $94.49B Pension Book

TL;DR: CalSTRS reported a $94.49B 13F book for 2026Q1, down -5.5% from $99.96B in 2025Q4, while the disclosed holdings count moved from 3054 to 2925. The casual read is “big pension owns mega-cap tech.” The more useful read is that this public pension allocator kept its U.S.-listed book broadly diversified while letting Nvidia, Apple, Microsoft and Amazon define the visible top of the filing.

California State Teachers' Retirement System, better known as CalSTRS, is a public pension allocator, not a hedge fund and not a passive index complex. Its own investment materials describe a broadly diversified portfolio built around long-term patient capital; the Form 13F-HR snapshot only shows the reportable U.S.-listed securities sleeve. The latest filing covers reportDate 2026-03-31 and accession 0001081019-26-000007.

That distinction matters. A $94.49B 13F filing from a public pension system is not a trading diary. It is a window into how the liquid public-equity sleeve sits inside a much larger retirement portfolio. In Q1 2026, the window shows a large-cap technology spine, an ETF ballast, and enough spread across the remaining book to avoid the concentrated profile associated with hedge funds.

What changed in CalSTRS' Q1 2026 13F?

The headline move is the reported 13F value: $94.49B in 2026Q1 after $99.96B in 2025Q4. The brief marks the quarter-over-quarter change at -5.5%, with holdings count moving from 3054 to 2925. That is a meaningful reset in the public-equity disclosure, but not a retreat from equities as an institution-wide statement. The 13F file is the listed-security layer, not the whole pension fund.

The top of the book stayed easy to recognize. Nvidia was the largest reported line at $6.40B and 7.35%. Apple followed at $5.65B and 6.49%, then Microsoft at $3.97B and 4.55%. Amazon added $3.03B and 3.48%, while Alphabet Class A stood at $2.55B and 2.93%.

The technology spine is clear, but the book is not all-in

The strongest visible data point is the mega-cap stack: NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, IVV, META and TSLA occupy the largest slots. That top list mixes AI infrastructure, software, cloud, internet platforms, electric vehicles and a broad-market ETF. For a pension allocator, the signal is not “one bold bet.” It is the way the largest liquid holdings cluster around companies that dominate benchmark risk and public-equity return attribution.

Broadcom at $2.11B and 2.42% extends the AI infrastructure theme beyond Nvidia. Alphabet Class C at $2.09B and 2.40% means the issuer appears through two share classes. iShares Core S&P 500 ETF at $1.93B and 2.22% provides a simple clue: this is still an allocator’s book, with broad-market exposure sitting beside individual stocks.

Why the -5.5% pullback should be read carefully

The eight-quarter history shows CalSTRS' reported 13F value rising from $68.41B in 2024Q2 to $99.96B in 2025Q4 before easing to $94.49B in 2026Q1. The Q1 move was a decline, but the disclosed value remained above $90.04B from 2025Q2 and $80.89B from 2025Q1. In other words, the pullback followed a strong run-up rather than a collapse back to early-2025 levels.

The holdings count gives the same “trim, not transformation” message. The count moved from 3054 in 2025Q4 to 2925 in 2026Q1, but the top holdings still read like a broad public-equity benchmark with large technology weights. That makes the quarter useful for monitoring allocation pressure, not for labeling CalSTRS as a directional stock picker.

How investors should use this CalSTRS filing

Retail investors should treat the CalSTRS 13F as context for market ownership, not as a copy-trade list. A public pension system has benefit obligations, liquidity needs and governance constraints that differ from a hedge fund’s incentive structure. When CalSTRS shows $6.40B in NVDA or $5.65B in AAPL, the useful question is how those exposures sit within a diversified public-equity sleeve.

The practical takeaway is threefold. First, mega-cap technology still dominates the visible top of a very large institutional book. Second, the 13F value slipped from the prior quarter but stayed high in the eight-quarter history. Third, concentration is present at the top but not extreme enough to define the entire portfolio, because the “Other” bucket in the concentration chart remains $55.90B and 64.17%.

• For stock-level monitoring: compare CalSTRS' NVDA, AAPL and MSFT positions with other institutional holders.
• For pension context: remember that 13F excludes major non-13F asset classes and does not represent the whole retirement system.
• For quarterly tracking: watch whether the $94.49B reported book rebounds, keeps compressing, or rotates away from the current mega-cap leaders.
