# BlackRock's $5.9 Trillion Q4 2025 Filing Has 50,216 Positions — More Than Any Other 13F Filer on Earth

> BlackRock's Q4 2025 13F reports $5.92 trillion across a record 50,216 positions. NVDA leads at 6.13%, but the real story is the breadth: 50,000+ line items mapping every corner of U.S. equities.

BlackRock, Inc. filed its Q4 2025 13F reporting $5.92 trillion across 50,216 positions — the most individual line items of any 13F filer in the world and a 3.6% increase from Q3’s $5.71 trillion. TL;DR Total 13F AUM: $5.92 trillion (up 3.6% QoQ from $5.71T) Positions: 50,216 — the broadest 13F filing globally Top holding: NVIDIA (NVDA) at $362.8B (6.13%) Top-5 concentration: 21.5% in NVDA, AAPL, MSFT, AMZN, GOOGL YoY AUM growth: +19.7% from $4.94T in Q4 2024 Position count change: +1,186 from Q3 (49,030 → 50,216) Key difference vs Vanguard: 2.9x more positions but 86% of the AUM The World’s Most Granular 13F BlackRock’s 50,216 positions dwarf every other filer. For comparison, Vanguard holds 17,686 and State Street holds 4,288. The reason: BlackRock reports each fund’s holdings separately across its iShares ETF family, resulting in significant overlap at the line-item level.

AUM Growth: Steady March Higher BlackRock’s trajectory over six quarters: Q3 2024: $4.76T → Q4 2024: $4.94T (+3.7%) Q1 2025: $4.76T (-3.6%) → Q2 2025: $5.25T (+10.3%) Q3 2025: $5.71T (+8.7%) → Q4 2025: $5.92T (+3.6%) BlackRock vs Vanguard: The Rivalry in Numbers MetricBlackRockVanguard 13F AUM$5.92T$6.90T Positions50,21617,686 NVDA Weight6.13%6.13% AAPL Weight5.31%5.62% Top-5 Share21.5%22.0% The near-identical NVDA weights (both 6.13%) reflect how both firms track the same market-cap-weighted benchmarks. Vanguard leads on AUM; BlackRock leads on breadth. What Analysts Might Misread “50,000 positions means BlackRock is more diversified.” Not necessarily. Many are overlapping ETF holdings of the same underlying stocks. The consolidated top-10 concentration is nearly identical to Vanguard’s. “BlackRock is losing to Vanguard.” On 13F AUM, yes. But 13F filings don’t capture BlackRock’s massive fixed-income, alternatives, and international AUM. Total firm AUM exceeds $11 trillion. How many positions does BlackRock hold? BlackRock reported 50,216 positions in its Q4 2025 13F — the most of any filer globally. This reflects its expansive iShares ETF family. What is BlackRock’s top holding? NVIDIA (NVDA) at $362.8 billion, representing 6.13% of the portfolio, identical in weight to Vanguard’s NVDA allocation. Is BlackRock bigger than Vanguard? In total firm AUM, BlackRock leads globally (~$11T+). But in U.S. 13F-reportable equity assets, Vanguard ($6.90T) exceeds BlackRock ($5.92T) by about $1 trillion.
