📈 10-Year Forward Outlook 2026-2036 (horizon hypothesis, not advice)
The record is what it is: Co-Founder & General Partner | Andreessen Horowitz | Machine Age Fund lead. Nothing below is filed — it is the shape the seat would take if the current trajectory holds, and it is re-scored every time a new public source lands.
🔭 first close size on the next vehicleExpect the mandate to widen before it deepens. Watch whether Andreessen Horowitz (a16z) adds an adjacent function to the seat rather than a bigger title on the same one.
🔭 co-invest pattern with strategicsA second mandate is the normal move here — a board seat, a fund-side advisory role, or an operating chair next to the current one. The tell is a first public co-signature, not an announcement.
🔭 whether a flagship is marked downFirst capital event window. Either a priced round behind Andreessen Horowitz (a16z) or a personal vehicle appears. Watch whether a flagship is marked down rather than the headline valuation.
🔭 dry-powder deployment paceJurisdictional switch is the highest-probability structural change from Menlo Park, CA, USA. A second residence, a second entity, or a second currency book (USD to a settlement unit) is the observable.
🔭 LP composition changesInstitutional shell forms: a holding vehicle, a family-office wrapper or a named co-investment club. Shells are quiet — the disclosure arrives through registry filings, not posts.
🔭 first close size on the next vehicleDistribution becomes the constraint. At this horizon the question is who carries Andreessen Horowitz (a16z)'s output and this seat's name, and on what terms. Watch dry-powder deployment pace.
🔭 co-invest pattern with strategicsSuccession pressure. Either a named deputy appears under the seat or the seat is re-scoped away from day-to-day. Both read as the same signal from outside.
🔭 whether a flagship is marked downSecond-order liquidity: secondary sales, a tender, or a strategic minority into Andreessen Horowitz (a16z). This is where an OSINT file usually goes stale for six months and then re-prices.
🔭 dry-powder deployment paceRecord consolidation. By here the file should be readable as a single arc rather than a list of events, and the Menlo Park, CA, USA base stops being the interesting part.
🔭 LP composition changesEnd-of-horizon check. Re-read 2026 against 2036: the useful output is which of the eleven rows actually printed, and which were noise carried by the market rather than the person.
🔭 first close size on the next vehicle🔍 Deterministic horizon model: every row is derived from facts already on this record and re-scored when a new public source lands. No forecast value is asserted.
