Weights use BlackRock’s complete reported 13F value as the denominator. The page materializes a bounded top-250 plus material-events universe, so additional securities may exist in the source filing.

Answers to common questions about the latest reported 13F portfolio and how to interpret it. BlackRock, Inc.’s latest verified Form 13F snapshot for Q2 2026 reports 249 primary non-option positions with reported portfolio value unavailable. The filing date was Aug 7, 2026. Portfolio weight is calculated across the primary non-option holdings shown in the tracker. Reported puts and calls are excluded from this denominator and, when present, are displayed separately. No. Form 13F is a quarter-end holdings disclosure filed later. It does not reveal exact transaction dates or execution prices. MarketInsiderLab therefore labels filing-basis and reference-price metrics as estimates and withholds unsupported values. BlackRock, Inc. currently has 1 reported option position in the latest filing. They are shown separately because option-reported values are not equivalent to ordinary equity ownership and are excluded from primary portfolio weighting.COMMON QUESTIONSBlackRock, Inc.

Signals
Fresh SEC ownership signals from Schedule 13D and 13G disclosures, separate from the quarterly 13F portfolio.
Answers about 13D/13G ownership signals, Item 4 intent and filing freshness. No ownership signal currently passes the publication gate for BlackRock, Inc.. Unsupported, ambiguous or unverified disclosures are withheld rather than guessed. A 13F is a delayed quarter-end holdings snapshot. Schedule 13D and 13G filings can disclose significant beneficial ownership between 13F reports, and a Schedule 13D can also reveal activist, strategic, board-related or control intentions. Item 4 describes the purpose of the transaction. It can matter even when the reported ownership percentage barely changes because the filing may disclose board activity, strategic proposals, transaction discussions or explicit control-related intentions. MarketInsiderLab publishes an intent classification only when the filing language supports it. The ownership engine records precise SEC scan timestamps. The latest recorded SEC scan for the current ownership pipeline was Sep 25, 2026 01:45 UTC. Published signals retain their source filing and processing timestamps.COMMON QUESTIONSBlackRock, Inc.

How verified quarter history, exits, re-entries and withheld periods are handled. The currently available canonical history runs from Q3 2016 through Q2 2026, with 40 quarters marked READY. This describes the verified history currently available in the tracker and does not claim completeness before the oldest supported filing. No. The history compares verified quarter-end disclosures. It can show that a position appeared, increased, decreased, remained unchanged or disappeared between filings, but it does not infer an exact transaction date that the SEC filing does not provide. A full reported exit ends the prior filing-basis episode. If the security later reappears, the backend treats it as a new episode rather than carrying the old basis through the gap. Historical values are withheld when continuity, identity, price, filing-basis or source evidence is not strong enough to support the metric. The tracker is designed to fail closed rather than fill gaps with unsupported assumptions.COMMON QUESTIONSBlackRock, Inc. Filing History FAQ

Methodology
Coverage is bounded to BlackRock’s top reported positions and material events rather than every security in each Form 13F. Source filings may contain additional securities, and 13F filings do not reveal exact trade dates or execution prices.
Official Form 13F filings and the canonical MarketInsiderLab filing record are authoritative. Unsupported or unverified data is withheld.
Portfolio weights use the verified full filing total. Security identity and corporate actions are reconciled before publication.
Changes compare verified SEC-reported quarter-end positions. They do not represent exact trade dates, execution prices, or intraperiod activity.
What Form 13F can — and cannot — show
These pages track the reporting manager’s public 13F disclosures. A 13F is a delayed quarter-end snapshot, not a complete or real-time portfolio.
The filing mainly shows long positions in reportable 13F securities, not every asset or exposure. Cash, short positions, private investments, many bonds and other non-reportable holdings can sit outside the filing.
Reported puts and calls are kept separate from ordinary shares, and their reported values should not be read as cash invested. Share classes, ticker changes, splits and supported corporate actions are reconciled; unresolved identity or continuity issues are withheld.
On Investor Portfolios, Concentrated means the top five reported holdings are at least 60% of reported portfolio value; Diversified means 35% or less. Profiles between those thresholds are in neither quick filter.
Estimate definitions
Reported filing data and calculated estimates are kept separate. Estimates are published only when the required inputs pass validation.
The latest verified price held by this tracker, dated as shown. It is not necessarily a live quote.
Reported holding value divided by reported shares after unit validation. It is not a purchase price or an independently verified market close.
A calculated per-share reference from verified filing history and split-adjusted reported changes. It is not actual purchase price or tax basis; a limited-history date marks the reference start.
Published only when four consecutive quarterly estimates pass QA and the weakest leg has at least 70% measurable coverage. Because the estimate is derived from quarter-end filing snapshots, it does not capture all intraperiod trading, cash or non-13F assets and is not an audited fund return.

Sources, calculation rules, continuity checks and the fail-closed publication policy. The tracker is built from verified SEC filings, primarily Form 13F for portfolio holdings and Schedule 13D/13G for significant beneficial-ownership disclosures. Market-price layers are used only where the methodology explicitly allows them. It is an economic interpretation derived from the SEC-reported value and reported shares for a filing observation. It is not presented as the investor’s actual purchase price or execution price. Security continuity and corporate-action checks are applied before publishing history, basis and performance metrics. When continuity cannot be established confidently, affected calculations are withheld rather than forced across incompatible observations. The system withholds output when required source evidence, security identity, continuity, price data or methodology conditions are not sufficient. This fail-closed policy is intentional: unsupported precision is not published.COMMON QUESTIONSBlackRock, Inc. Methodology FAQ
