Three tracked deals totaled $1.3B disclosed. Castelion (Series C, $800M, $13B post) is the week's standout — defense-tech continues to absorb late-stage capital at scale, with JPMorgan's Strategic Investment Group, a16z, and Carlyle co-leading. Higgsfield (Series B, $400M, $5.4B post, DST) confirms AI-model funding remains open at multi-billion marks. Rillet (Series C, $100M, $1.0B post, ICONIQ) reached unicorn status — AI accounting is a narrow but validated wedge. Outside the tracked tape: Starcloud raised $250M for orbital AI data centers (Nvidia-aligned); Devoted Health is reportedly raising at a $25B valuation; Groq raised $350M at $3.5B pivoting to Nvidia-powered inference cloud; Form Energy secured $750M Series G (T. Rowe Price). Deal count is thin (3 tracked), but ticket sizes are large — capital is concentrating, not broadening.
Disclosed round capital in the window. Undisclosed amounts count as zero.

Where the window's activity sits on the funding ladder: deal count (solid) against disclosed capital (faded) per stage, with the companies behind each cluster. Stages come from the reported round labels; undisclosed amounts count as zero capital.
Most-active leads each did a single deal this week — JPMorgan SIG, a16z, and Carlyle collectively placed $800M into Castelion; DST put $400M into Higgsfield; ICONIQ $100M into Rillet. No firm appears more than once. On the fundraising side: Crestline raised $625M for a European fund; Makers Fund closed Fund IV at $250M ($1.5B AUM) on the back of top-1% Fund I performance. The signal: LP capital is flowing to established managers with track records, and check writers are placing concentrated bets rather than spreading across many deals. New-fund formation is happening but at modest scale.
| Lead Investor | Deals | Disclosed Capital |
|---|---|---|
| JPMorganChase's Strategic Investment Group, Andreessen Horowitz & Carlyle | 1 | $800M |
| DST Global | 1 | $400M |
| ICONIQ | 1 | $100M |
Nvidia is the central actor. It is acquiring Poolside's 'Model Factory' and 109 employees for $6B per the-decoder.com, with a broader $7B licensing-and-investment deal reported by TradingView. Nvidia stock ended the week down 5%. Separately, Nebius is competing with Nvidia and Amazon for a $7B Decart AI deal. SpaceX reportedly sought to acquire Cognition (AI coding); CEO denied talks. No closed M&A within the 2,152 tracked set this week — activity is headline-driven and concentrated in AI infrastructure and tooling. The pattern: incumbents are buying teams and IP rather than entire companies in some cases, blurring the line between acquisition and licensing.

The Silicon Valley Private Market Daily — the 8pm PT desk close: qualified raises, roster re-rates and sector velocity from the QL private-market pipeline.
The private market landscape is currently defined by significant capital concentration in AI infrastructure, energy, and space, with high-valuation rounds continuing despite broader macro uncertainty. While established firms like Reach Capital maintain conviction in early-stage AI applications, heavy corporate investment—specifically from Nvidia and Google—is dictating the pace of capital deployment. Market data shows a growing split between well-funded, critical infrastructure startups and a large cohort of enterprise software firms facing valuation pressure or exit difficulty.

Down-round & valuation headlines scraped at publication from Google News, Hacker News, CNBC, Yahoo Finance and the wider tech press.
Castelion's $800M at $13B shows defense can absorb nine-figure rounds. If you're in dual-use or defense, the capital window is wide — but expectations on revenue traction and government contracts are commensurate.
120 companies scored, 100 on watch. Harvey cut 29%, Asimov -18.7%, Wonder -16.2%. Late-stage founders should model downside scenarios and prioritize path-to-profitability narratives over growth-at-all-costs.
The Poolside structure — acquiring a division plus team for $6B while broader licensing reaches $7B — suggests incumbents want talent and IP without full integration. Founders should understand which assets acquirers actually want.
Capital is concentrating into defense and AI infrastructure at billion-dollar scale while the broader market stays thin — 3 tracked deals, 100 companies on markdown watch. Nvidia's aggressive M&A and licensing posture will likely pull more AI-tooling companies into deal conversations, but the gap between mega-rounds and everyone else is widening. Expect markdowns to continue outpacing new mega-rou
