BlackRock Inc 13F Portfolio

The biggest dollar adds are a referendum on where BlackRock thinks incremental AI alpha now lives. They’re clearly shifting marginal emphasis from the obvious front-end beneficiaries to the under-owned back-end infrastructure that actually makes AI work at scale.

A few positions illustrate the point:

• KLA: A massive add (shares up +901.9%, value up by about $34.3B) at a reported gain_vs_avg_buy_pct of -85.0% is BlackRock buying into pain. That looks like a re-underwrite of AI manufacturing equipment after a severe drawdown, on the view that wafer inspection and process control are non-negotiable as fabs chase yield on advanced nodes.
• Marvell Technology: A +34.1% share increase and roughly $6.49B est_dollar_change says they see this as a core fabric for AI-era networking and custom silicon, not a peripheral player.
• Mega-cap platforms (Apple, Microsoft, Alphabet, Broadcom, Nvidia, Amazon): Each gets multi-billion-dollar incremental dollars despite already-large portfolio_pct stakes. That’s a judgment that these are still underpriced relative to their AI and cloud monetization optionality, not over-owned bubble stocks.

Around the edges, they quietly lean into cybersecurity (Palo Alto Networks, up +4.6% in shares) and AI-adjacent data/analytics (Palantir, up +0.4% even though gain_vs_avg_buy_pct is slightly negative). Those are smaller in dollar terms, but fit the same through-line: own the infrastructure stack, from transistors and tools up to data platforms and security.

If the buys tell you what they want to own for the next leg of AI, the trims tell you what they think is dead money or second-tier exposure. They are not broadly de-risking tech; they’re upgrading within it.

The most telling funding sources:

• Intel and Western Digital: Intel is cut by -4.7% in shares (about -$2.94B est_dollar_change), Western Digital by -7.9% (about -$1.80B). Both remain profitable trades on paper, but they’re yesterday’s PC/server and commodity storage proxies, not clean plays on AI leadership.
• Coca-Cola and Costco: KO is reduced -3.3%, COST -2.1%, despite strong long-run gains (COST’s gain_vs_avg_buy_pct is 285.0%). These are classic sources of liquidity when your view is that structural growth now lies in silicon, not soda and warehouse clubs.
• Old-line networking and diversified tech (Cisco, IBM, GE Aerospace) and traditional banks (JPMorgan, Citigroup): all see modest share reductions despite healthy gains_vs_avg_buy_pct in most cases.

Put differently, BlackRock is cashing in on stable, lower-growth or more cyclical winners and rolling that capital into the parts of the stack they believe have the greatest AI operating leverage. The cuts are surgical, not panic-driven, and stay away from their highest-conviction AI leaders.

At the sector level, the rotation is more nuanced than "more tech, less everything else," even if technology’s 62.89% share dominates the chart. The relative changes are small in percentage terms but meaningful given the scale of BlackRock’s book.

Technology inches higher, but within that bucket the internal migration is stark: more capital into semiconductors and equipment (Nvidia, Broadcom, Micron, AMD, Applied Materials, KLA, Marvell, Texas Instruments) and software/platforms with direct AI monetization (Microsoft, Alphabet, Meta, Oracle, Palo Alto Networks), and less in legacy compute, storage, and comms (Intel, Western Digital, Cisco, IBM, GE Aerospace).

Consumer exposure (9.78% vs 9.9% prior) shifts subtly from pure staples toward omni-channel and digital demand proxies. Amazon, Walmart, Home Depot, Netflix and Procter & Gamble all see incremental adds, while Coca-Cola and Costco supply cash.

Health care is a quiet but important stabilizer at 6.88%. They add to UnitedHealth and Merck while lightly trimming AbbVie and Johnson & Johnson, effectively tilting toward diversified earnings and away from more idiosyncratic drug risk. Finance (down to 4.23%) and Consumer Staples (0.77%) give up a little ground, while Energy nudges up to 2.10% as they buy more Exxon and Chevron — a cheap hedge if AI keeps driving power demand and commodity volatility.

Taken together, this 13F says BlackRock is not afraid of AI froth; they think this is an earnings super-cycle and want to own the full infrastructure stack. The marginal dollar goes into fabs, inspection tools, high-speed networking, and hyperscale platforms, not into cash or bond surrogates.

The KLA trade is the purest tell: ramping a position by +901.9% with a deeply negative gain_vs_avg_buy_pct is a conscious decision to average into what they see as mispriced, not a mechanical rebalance. Similar logic applies to the Marvell add and the sustained pushes in Nvidia, Broadcom and Micron.

On the other side of the ledger, they are harvesting gains from mature cash machines (Coca-Cola, Costco, Intel, Western Digital, Cisco, big banks) and converting them into higher-volatility, higher-upside AI infrastructure. That’s a classic expression of a high-conviction, long-duration view rather than a market-timing exercise.

If this reading is right, expect future quarters to continue this pattern: incremental capital into AI semis, equipment, and security; tightening within older tech and financials; and a persistent ballast in health care, consumer staples, and broad-market ETFs. The portfolio is built to participate fully if AI capex stays elevated for years, while still surviving if the macro backdrop gets choppy.
