| Company | Disclosed amount | Category as reported |
|---|---|---|
| Blue Origin | $10 billion | Mega-round |
| Databricks | $5 billion | Mega-round; listed among pure-technology transactions |
| Mistral AI | $3.5 billion | Mega-round |
| The Boring Company | $3 billion | Mega-round |
| Neko Health | $700 million | Healthcare and life sciences, Series C |

Technology took the largest share of deal volume by a wide margin. Pure technology transactions numbered 69, and once tech-enabled companies across financial services, industrials, energy and public services are included, FINTRX puts the technology footprint at well over half of all Q3 activity. Healthcare and life sciences contributed 27 transactions. In energy, Capricorn Investment Group, Foris Ventures and Emerson Collective ranked among the most active investors in its dataset.
Wealth-management consolidation shares top billing in the report's summary, but the reported figures do not separate wealth-management dollars from the $68.3 billion total or give a transaction count for RIA deals. PWD's own third-quarter tracking found RIA deal counts falling: DeVoe & Company counted 77 deals, down 17%, and said reaching its annual record now needs 79 in the fourth quarter.
Family-office capital may be underwriting platform-scale transactions that a quarterly deal count captures only once, but the reported figures do not establish that.
