# CPPIB's $149.52B Q4 Portfolio: Big Tech at Scale Without a Concentration Trap

> Canada Pension Plan Investment Board closed Q4 2025 at $149.52B with a top-5 concentration of just 20.1%, pairing mega-cap tech exposure with unusually broad diversification.

Canada Pension Plan Investment Board finished Q4 2025 with $149.52B in reported 13F AUM, but the real signal isn’t just size — it’s structure. Even with multi-billion-dollar positions in NVIDIA (NVDA), Apple (AAPL), and Microsoft (MSFT), the fund’s top-5 weight is only 20.1%, which keeps single-stock risk in check while preserving upside to mega-cap leadership. TL;DR Quarter: 2025Q4 Canonical AUM: $149.52B Holdings value sum: $145.39B Positions: 500 Top holding: NVDA at $8.38B (5.76%) Top-5 concentration: 20.1% AUM trend: $102.99B (2025Q1) to $149.52B (2025Q4) Read-through: scale plus breadth, not a narrow one-theme bet Filing Snapshot: Size Expansion With Diversification Intact CANADA PENSION PLAN INVESTMENT BOARD reported $149.52B in Q4 2025 across 500 positions with a WhaleScore of 73.00. The portfolio has grown sharply over the past year, but concentration remains moderate for a book of this scale. Metric Value Canonical AUM (2025Q4) $149.52B Holdings value sum $145.39B Positions 500 Top-1 concentration 5.8% Top-5 concentration 20.1% Top-10 concentration 29.1% Top Holdings: Mega-Cap Core, Position Sizing Discipline The leadership basket — NVDA, AAPL, MSFT, Amazon (AMZN), and Broadcom (AVGO) — contributes most of the directional equity beta. But each line is still sized to avoid overpowering the total book, which aligns with a pension allocator’s risk budget more than a high-conviction hedge fund template. AUM Path: Reacceleration Into Year-End After a softer patch around late 2024 and early 2025, AUM moved from $116.93B in 2025Q2 to $142.42B in 2025Q3, then to $149.52B in 2025Q4. That trajectory implies the fund participated in the broad market rebound while keeping a balanced exposure profile. What Stands Out in Q4 2025 First, CPPIB’s top holdings lean into the same mega-cap complex visible across global institutional books, yet concentration is still controlled. Second, holdings count has stepped higher in the latest quarter, suggesting wider deployment breadth. Third, this profile looks less like tactical chase behavior and more like a scalable, benchmark-aware accumulation framework.
