SAM ALTMAN QUALIFIED OPPORTUNITY FUND LLC is a private single-investor QOF self-certified via IRS Form 8996 — no SEC Form D filing found, consistent with non-public fund structure
EDGAR full-text search returned zero results for the fund. QOFs do not require SEC registration unless offering interests to outside investors. The absence of a Form D indicates this is a single-investor vehicle, likely deploying Altman's own capital gains from 2021 tech investment liquidations. Under TCJA 2017 (26 USC §1400Z-2), the fund must hold 90%+ of assets in Qualified Opportunity Zone property and file Form 8996 annually. Capital gains deferred until Dec 31, 2026; post-10-year appreciation permanently excluded from tax.

ALTMAN FAMILY LLC (CA #201525910397) is a previously undocumented California LLC in Altman's portfolio, formed approximately 2015
B2BHint.com entity aggregator lists ALTMAN FAMILY LLC with California entity number 201525910397. The CA entity number format places formation at approximately 2015. This entity was referenced separately from Altman Holdco in reporting on Pagaya Technologies (Carmen Beckwith signed as Authorized Signatory for Altman Family LLC in the Pagaya F-3 Registration Rights Agreement, Sep 30, 2024). This is the oldest named family LLC in the portfolio, predating Apollo RE LLC and the property holding LLCs.
SAM ALTMAN QUALIFIED OPPORTUNITY FUND LLC registered in Hawaii (HI #264766C6, cancelled) at 75-5520 Kona Bay Drive — one digit off from Altman's actual Big Island estate at 75-5530 Kona Bay Drive, Kailua-Kona HI 96740
The Hawaii registration of the QOF (Oct 20, 2021, three months after the $43M Big Surf LLC purchase) used 75-5520 Kona Bay Drive rather than the actual estate address (75-5530). The 75-5520 address has been owned by a different private party since 2007. This raises the question of whether the QOF was intended to hold a separate Opportunity Zone investment in Kailua-Kona — which has two designated OZ census tracts (Kealakehe and Kailua) — rather than the existing Big Surf estate, or whether the address was simply entered incorrectly. The HI registration was subsequently cancelled. The CA formation (Aug 2022) is the primary active registration.

Montana LLC cluster (Montvale Group, Oakland Collection, Hawthorne Lane Collective) represents a deliberate architectural shift to Montana jurisdiction for privacy and tax advantages starting September 2025
Three LLCs formed in Montana in a 10-week window (Sep 9 and Nov 18, 2025). Montana LLCs do not require public disclosure of member/manager names in the same way as California. Montana has no state capital gains tax (CA rate 13.3%). All three use Bozeman-area infrastructure: Montvale and Oakland Collection use local attorney Rebecca H. Pape (28 E Mendenhall, Bozeman MT) as registered agent, while Hawthorne Lane Collective uses CT Corporation System (3011 American Way, Missoula MT), which typically signals a larger or more complex transaction. All managed by Jennifer Serralta at her LA address (350 S. Grand Ave Ste 2000, Los Angeles). Geographic target is likely Gallatin County / Bozeman-area real estate.
