June 2025’s 10 Largest Family-Office Deals

Family offices are deploying larger tickets—and doing it quietly. In June 2025 they committed just over $2.5 billion across direct equity, credit, and fund vehicles. The pace underscores one lesson for capital-raisers: if you trust quarterly PDFs, you’re already late. Every transaction below hit the Altss OSINT feed within hours, while most conventional platforms posted days later.

What June’s Activity Signals for Allocators

“Family-office capital is behaving like late-cycle private equity: disciplined on price, ruthless on speed, and indifferent to labels.”

Rising rates and patchy IPO windows push dealmakers toward flexible private liquidity. Family offices, unburdened by fund lives, are stepping into that gap—whether by anchoring cat-bonds, extending structured credit, or seeding new managers. The implication for GPs: relationship depth now outranks brand name.
