Share counts, net assets & marks
⚠ Estimated, not company reported — fund share counts, net assets & marks are rolled forward together. Strategic rows do not move. DXYZ last filed NAV is $24.56 as of 2026-03-31.
ATM / inflows
DXYZ and ARKVX raised new capital after the filing. If that cash bought more of the same names, look-through is roughly unchanged; if it sits in cash, per-$100 falls. Default is the range until the next N-PORT pins it.

Click a row for the source arithmetic. As-of staleness: ●amber >90 days · ●red >180 days. Evidence is per-leg in the expanded panel.
Gross scenario estimates assembled from public filings and issuer disclosures. Figures may combine different source dates, security classes and valuation methodologies. They are not NAV, liquidation value, expected proceeds or price targets, and they exclude taxes, fees, carry, liabilities, preferences, transfer restrictions, lockups and future financing. Review each row's source and calculation before relying on it.
† Convertibles, preferred, capped stakes and commitments do not scale linearly with IPO valuation.
Underlying Open Source Data
Every figure on this page is typed by the kind of evidence behind it, carries its own as-of date, and cites a source. Ownership percentages are derived from filings — never stored as a hand-authored stake. Where no primary source supports a percentage, none is published. The calculator is one consumer of a public dataset; you can reproduce every published figure without running the site.
Schema, methodology and a standalone calculator live in github.com/bolewood/stocks-bolewood. Cite a dated tag rather than main, so the numbers behind a reference do not move.
Two-line prompt — paste into an LLM to audit the dataset:
Check https://github.com/bolewood/stocks-bolewood: read data/METHODOLOGY.md and data/wrappers/, then run npm run reference.
Confirm every published Anthropic/OpenAI percentage is derived (not stored), each record has a basis, source and as-of date, and stocks.bolewood.com/ai matches reference/expected-results.json at the same inputs. Report any unpublished stake, mixed Filed/Estimated inputs, or unreproducible figure.
Sources & footnotes
Implied exposure is not always ownership. Disclosed means an issuer or investor stated a percentage. Filed FV-equiv is fair value ÷ the round that marked it. Round-implied is dollars invested ÷ post-money. Commitment has no percentage. DXYZ OpenAI PPUs are excluded (not equity).
GOOG · Alphabet Inc.
Security: Common (15% cap). ~14%, contractually hard-capped at 15% (NYT / court docs, 2025-03-11). 14% as of Mar 2025; later rounds may have diluted unless Alphabet bought more. Class A 5,868M + B 835M + C 5,527M = 12,230M (10-Q 2026-06-30). GOOG price × all classes ≈ Alphabet market cap. Anthropic: Court documents: ~14%, contractually hard-capped at 15%, non-voting. NYT reporting on those court documents. 10-Q does not name Anthropic. Implied exposure ≤14.00% Anthropic / — OpenAI.
AMZN · Amazon.com Inc.
Security: Conv + Pfd. Anthropic: $92.5B preferred + $97.9B convertible notes (AMZN 10-Q as of 2026-06-30). Conversion terms undisclosed. Anthropic is filed carrying-value equivalent, not an ownership %. OpenAI is round-implied from the $50B Series C. 10-Q cover. Anthropic: Nonvoting preferred $92.5B + convertible notes FV $97.9B = $190.4B. $100B AWS is not equity. Conversion terms and any ownership cap are undisclosed. Series H $965B post-money. OpenAI: $15.0B Series C in Q1 + $13.7B in Q2 = $28.7B on the 2026-06-30 balance sheet; subsequent event funded the remaining $21.3B, completing $50B. $100B AWS is not equity. $852B post-money. Anth. FV $190.40B at $965.00B (2026-06-30). Implied exposure 19.73% Anthropic / 5.87% OpenAI.
MSFT · Microsoft Corporation
Security: Equity. 27%, only Big Tech % in an SEC filing (MSFT 10-Q as of 2026-03-31). OpenAI 27% is the only Big Tech percentage in an SEC filing. Anthropic: Capital committed to Anthropic; ownership percentage not disclosed. No primary issuer filing states a percentage. OpenAI: ~27% of OpenAI as-converted, equity method. Implied exposure — Anthropic / 27.00% OpenAI.
SFTBY · SoftBank Group ADR
Security: VF2 Pfd. OpenAI is Vision Fund 2 preferred; SoftBank ~13% at $64.6B (2026-02-27 release). No Anthropic. OpenAI is Vision Fund 2 preferred. Issuer-equivalent ADR shares (2× Tokyo common). Citi ORD:DR is 1:2 — each SFTBY ADR is ½ of one 9984.T share. Tokyo common 5,698,923,701 (issued 5,711,848,120 − treasury 12,924,419) as of 2026-03-31. OTC ADR prints ~½ the USD-converted 9984.T price, so 2× common × ADR quote ≈ full-issuer cap. NAV ¥58.3T vs market cap ¥31.46T ≈ 46% discount (pro forma 2026-08-05). Arm is ~60% of holdings (¥49.91T / ¥83.11T, SBG Q1 FY2026 data sheet 2026-06-30); Vision Funds (SVF1+SVF2+LatAm) ~28.8%; SoftBank Corp. ¥2.79T; T-Mobile adjusted to ~0 after asset-backed finance. LTV 13% against a 25% policy cap, plus a recent $40B bridge loan and $10B margin loan secured by the OpenAI stake. The high per-$100 reflects the NAV discount, not OpenAI concentration. SBG's OpenAI exposure sits partly inside SVF2 — do not double-count it against the Vision Fund line. OpenAI: ~13% upon completion of the investment program ($64.6B by 2026-10-01), not current funded ownership. ~$55B in as of Aug 2026; last $10B tranche due 2026-10-01. Implied exposure — Anthropic / 13.00% OpenAI.
NVDA · NVIDIA Corporation
Security: Undisclosed. OpenAI is round-implied from OpenAI's $30B announcement. Anthropic is a commitment with no ownership %. Neither figure is an NVDA-disclosed ownership percentage. Anthropic: Up to $10B Anthropic commitment (Huang / Nov 2025 announcement). Not an NVDA 10-K ownership %. OpenAI: OpenAI round announcement: Nvidia invested $30B. Not an NVDA 10-K ownership %. $852B post-money. Implied exposure — Anthropic / 3.52% OpenAI.
SKM · SK Telecom Co.
Security: Equity. Anthropic equity; % not issuer-disclosed (Aug 7 table / Hana ~0.30%). Anthropic 0.30% (range 0.30–0.70%). No OpenAI.

AGIX · KraneShares Public-Private AI ETF
Security: Fund NAV. Look-through from filed fair value ÷ the round used to mark that FV. Not the SingularityNET token. No OpenAI in disclosed holdings. Public-Private AI ETF: Anthropic is a small NAV sleeve (~1.9–2.8%), which is why look-through is a few dollars per $100. ETF share count drifts with creations/redemptions. Anthropic: Holdings page: Anthropic PBC $12,926,025 (1.92% of NAV). NAV weight has printed ~1.9–2.8% (Mar 31 report 2.7%; Jul 31 blog 2.82%). Anth. FV $12.9M at $965.00B (2026-08-18).
