Blackstone Inc.

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 2,095 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.

What a reader needs to know to read these numbers

• The 13F exclusion, read this first. Blackstone Inc. (CIK 0001393818) files its own Form 13F-HR as an institutional investment manager. Its most recent filing, for the quarter ended 30 June 2026 (filed 14 August 2026), contains 557 information-table rows. These are positions held for Blackstone's insurance and other managed/advisory accounts, not Blackstone Inc.'s own corporate balance sheet. None of those 557 rows are converted into holdings here, per the brief's exclusion of client and index-fund-style positions.
• Holdings is empty and that is the sourced finding. The FY2025 10-K (filed 27 Feb 2026) and the Q2 FY2026 10-Q (period ended 30 June 2026, filed 7 Aug 2026) were searched in full for 'equity method', 'non-marketable', 'measurement alternative', 'general partner', 'co-investment' and 'investments'. What was found: (1) 'Equity Method Investments' on Blackstone's own balance sheet ($6,535,521 thousand at 30 June 2026, Partnership Investments line) are, by the 10-Q's own words, Blackstone's investments in Blackstone Funds that it does not consolidate but has significant influence over, i.e. Blackstone's own GP and co-investment stakes in ITS OWN managed funds. Per the brief, an interest in Blackstone's own fund is not a stake in another company, so this entire balance is excluded. (2) 'Corporate Treasury Investments' ($401,465 thousand at 30 June 2026) are explicitly described as investments into 'primarily fixed income securities, mutual fund interests, and other fund interests', i.e. treasury/cash management, excluded under the brief's money-market and treasury exclusion. (3) 'Other Investments' ($8,510,174 thousand at 30 June 2026) is a combined bucket described as 'equity method investments where Blackstone has elected the fair value option and other proprietary investment securities held by Blackstone, including equity securities carried at fair value, equity investments without readily determinable fair values, and senior secured and subordinated notes in non-consolidated CLO vehicles.' Within it, the 10-Q separately discloses that 'equity investments without a readily determinable fair value had a carrying value of $517.2 million as of June 30, 2026' but does not name or size any individual investee within that $517.2 million. Per the brief's rule that a combined balance covering many investees sizes none of them, this figure is recorded here in notes rather than distributed across guessed investees.
• Blackstone Inc. discloses in its own 10-K risk factors that it 'does not have any material assets other than its general partner interests in the Blackstone Holdings Partnerships and its equity interests in certain wholly owned subsidiaries.' This is the Up-C holding-company structure: Blackstone Inc. the public filer is largely a holding shell over the operating partnerships, which is why its own balance sheet does not carry named, per-investee minority stakes the way BlackRock's does (BlackRock names iCapital, Circle, Envestnet, etc. individually; Blackstone does not name any comparable holding at the Blackstone Inc. level in either filing checked).
• Blackstone-managed permanent-capital vehicles that are separately SEC-registered and separately traded, specifically Blackstone Mortgage Trust (BXMT, NYSE), Blackstone Secured Lending Fund (BXSL, NYSE), Blackstone Digital Infrastructure Trust (BXDC, NYSE), Blackstone Private Credit Fund (BCRED) and Blackstone Real Estate Income Trust (BREIT, non-listed), are all named in the 10-K as funds Blackstone manages and earns fees from. Neither the 10-K nor the 10-Q discloses a specific Blackstone Inc. ownership percentage in any of these named vehicles, and none is described as consolidated by Blackstone Inc. on its own balance sheet (the consolidation note describes only Blackstone-controlled VIEs and majority-owned subsidiaries generically, with no BXMT/BREIT/BXSL-specific consolidation language found). Per the brief's instruction to record a stated percentage in a named listed entity as a holding when disclosed, no holding is recorded for any of these because no percentage is disclosed at the Blackstone Inc. level; the shares seen in each manager's 13F above (e.g. Vanguard, BlackRock, State Street, Morgan Stanley, JPMorgan, Geode all separately hold BXMT/BXSL/BXDC positions as different CUSIPs/issuers from Blackstone Inc. common stock) are those OTHER companies' own shareholders, not Blackstone Inc.'s stake in them.
• A live example of the fund-versus-firm trap, found and excluded. A Schedule 13D/A filed 21 May 2024 (accession 0001193125-24-143963) on Autolus Therapeutics plc (CUSIP 05280R100, an unrelated biotech, NOT Blackstone Inc. stock) lists Blackstone Inc. as a joint reporting person at the top of a beneficial-ownership chain: BXLS V - Autobahn L.P. (a Blackstone Life Sciences fund) -> its GP entities -> ultimately Blackstone Holdings I L.P. -> Blackstone Holdings I/II GP L.L.C. -> Blackstone Inc. This is the standard SEC beneficial-ownership chain disclosure for an asset manager's controlled fund, not a Blackstone Inc. corporate-balance-sheet investment: the actual capital is Blackstone Life Sciences Fund V's, contributed by that fund's outside limited partners. It is excluded from holdings for the same reason the 557 client 13F positions are excluded.
• On 9 June 2026 Broadcom, Apollo and Blackstone's Credit and Insurance business announced the AI XPV Platform, a $35 billion initial capital solution anchored by Apollo and Blackstone. Checked Blackstone's own Q2 FY2026 10-Q (period ended 30 June 2026, the first filing after the announcement) for 'XPV', 'AI Investment Partnership', 'Data Center' and 'Anthropic': no mention of the XPV Platform or a Blackstone Inc. equity/ownership interest in it appears. This is consistent with Broadcom's own research file, which records that the Apollo press release names only Apollo and 'Blackstone's Credit and Insurance business' (a managed-fund platform, not the Blackstone Inc. corporate balance sheet) as anchor investors.
• The governance story: Blackstone Inc. (CIK 0001393818) has filed zero DEF 14A proxy statements in its entire EDGAR history, confirmed via both the browse-edgar company filing feed (type=DEF 14A, zero results) and EDGAR full-text search for 'Stephen A. Schwarzman' restricted to DEF 14A filings under this CIK (zero results), both checked 17 August 2026. The 10-K explains why: the Series II Preferred Stockholder (Blackstone Group Management L.L.C., wholly owned by Blackstone's senior managing directors and controlled by Stephen A. Schwarzman) 'holds more than 50% of the voting power for the election of directors,' making Blackstone Inc. a NYSE 'controlled company.' Blackstone states it is 'not required to file proxy statements or information statements under Section 14 of the Exchange Act except in circumstances where a vote of holders of our common stock is required under our certificate of incorporation or Delaware law,' and it is also exempt from Dodd-Frank say-on-pay votes. Item 12 of the 10-K itself (rather than an incorporated-by-reference proxy) is therefore this research's source for the beneficial ownership table.
• The Series I Preferred Stockholder is Blackstone Partners L.L.C., also owned by Blackstone's senior managing directors and controlled by Schwarzman, holding the single outstanding share of Series I preferred stock. Series I holders collectively cast one vote per Blackstone Holdings Partnership Unit held by the Holdings limited partners (voting together with common stock as a single class), representing approximately 37.5% of the combined voting power of common stock and Series I preferred stock as of 20 February 2026. This is a separate voting mechanism from the Series II Preferred Stockholder's director-election control described above; both are ultimately controlled by entities Schwarzman controls.
• Common stock outstanding differs by date across this file depending on the source: 752,601,287 shares issued and outstanding at 30 June 2026 (10-Q balance sheet), versus 750,625,114 shares outstanding as of 31 July 2026 (10-Q cover page, used as company.shares_outstanding here and as the register's percentage denominator for all 30 June 2026 13F rows). The 31 December 2025 Vanguard row uses 748,688,068, the balance sheet's prior-period column.
• Market capitalisation reconciliation. The $179.02 billion market cap published by stockanalysis.com as of 14 August 2026 does not reconcile to 750,625,114 common shares at the $143.93 close that day (which implies only about $108.0 billion). The gap is explained by Blackstone's Up-C structure: market-cap trackers commonly compute Blackstone's capitalisation on an as-exchanged, fully diluted basis that includes Blackstone Holdings Partnership Units (economically identical to common stock, exchangeable 1-for-1). Adding the 10-Q's weighted-average Holdings unit count for H1 2026 (444,174,696) to the 750,625,114 common shares gives approximately 1,194,799,810 as-exchanged shares, which at $143.93 is approximately $172.0 billion, close to but not exactly matching the $179.02 billion figure (the residual gap is likely a slightly different, more current Holdings-unit count or per-share price used by the source rather than the H1 2026 weighted average used here). company.shares_outstanding in this file is common stock only (750,625,114), not the as-exchanged figure.
• Blackstone has a single class of common stock (one vote per share) plus the two single-share preferred instruments (Series I and Series II) described above; there is no dual-class common stock structure of the kind seen at, for example, Alphabet or Meta. All the voting control is concentrated in the two preferred shares rather than in a second class of common stock.
• Register percentages against common stock are computed by this research against the stated share counts noted above, except where the source states its own percentage (Capital World Investors' 5.3%, noted alongside this research's 5.076% recomputation against a later share count).
