# Marc Andreessen Holdings Structured map of [[Marc Andreessen]]'s firm, funds, and the **dual crypto/defense portfolio** that is the engine of both his wealth and his conflicts. The people side is [[Marc Andreessen First Degree Connections]]; the canonical [[Marc Andreessen]] page carries the narrative. > Most exposure is via [[Andreessen Horowitz]] fund positions, not personal holdings. Figures as last reported in the vault (see [[Marc Andreessen News Log]]). ## The firm [[Andreessen Horowitz]] (a16z) — co-founded 2009 with [[Ben Horowitz]]. Raised **$15B** in January 2026 — the firm's largest ever. The two practices that matter for this KB: | Practice / fund | Size | Focus | |---|---|---| | [[American Dynamism]] | $1.176B (from $500M in 2023) | Defense, aerospace, public safety, manufacturing — Pentagon-dependent | | a16z crypto fund | $4.5B | One of the largest dedicated crypto funds | ## The dual-portfolio problem (the load-bearing section) The same firm funds **both the weapons and the financial rails**, while its founder recruits the people who regulate both — the conflict mapped on the canonical page and in [[Defense Tech Conflicts of Interest]]: | Domain | a16z investment | Policy influence | |---|---|---| | Defense / AI | $1.176B [[American Dynamism]] | [[DOGE Ecosystem]] talent recruitment; AI-policy shaping | | Crypto | $4.5B crypto fund | $33.5M [[Fairshake]]; stablecoin lobbying; [[GENIUS Act]] | | Legislation | Fairshake-backed candidates | GENIUS Act, CLARITY Act, SEC deregulation | No formal government role ⇒ no disclosure, no recusal, no ethics review. ## Portfolio companies in this KB a16z is a cross-investor across the [[Musk-Thiel Funding Map]]. KB-tracked positions include [[Anduril]] (defense) and [[Flock Safety]] (surveillance), plus crypto issuers. The full portfolio is a firm-level record under [[Andreessen Horowitz]], not duplicated here. ## Wealth & real assets Wealth is primarily a16z carry plus the Netscape/Opsware exits. On the [[California Tech Exodus Ecosystem]] map, Andreessen is the **counter-case**: he kept **Atherton** (the country's most expensive zip code) as his primary residence while [[Ben Horowitz]] moved to Las Vegas and the firm re-domiciled to Nevada — and fought a local multi-family zoning change, the cleanest "which Californians" hypocrisy in the exodus file. ## See Also - [[Marc Andreessen]] — canonical biography - [[Andreessen Horowitz]] · [[American Dynamism]] - [[Marc Andreessen Political Donations]] · [[Marc Andreessen First Degree Connections]] - [[Musk-Thiel Funding Map]] - [[Marc Andreessen Dossier]]
