Family offices took part in 342 Q3 2026 deals with $68.3 billion disclosed capital

Family offices took part in 342 company transactions totaling $68.3 billion of disclosed round capital in the third quarter of 2026, according to FINTRX. InvestmentNews reported the figures on Oct. 16 from the Q3 2026 Family Office Investment Activity Report.

The report counts 161 family offices investing in 319 companies across the 342 transactions between July and September. Real estate sits outside that tally: 23 property transactions in the quarter carried $2.41 billion of disclosed value.

Disclosed round sizes averaged $260.7 million against a median of $34.5 million. Four rounds account for $21.5 billion, about 31% of the quarter's total: Blue Origin raised $10 billion, Databricks $5 billion, Mistral AI $3.5 billion and The Boring Company $3 billion, each with at least one family office participant.

FINTRX describes wealth management consolidation as one of the forces dominating family office activity, but the reported figures give no separate count, value or multiple for wealth-management transactions.

Pure technology transactions numbered 69. Including technology-enabled companies in financial services, industrials, energy and public services, technology was well over half of Q3 activity.
