This week’s private-market tape looked more institutional than euphoric. Capital kept flowing to differentiated AI managers and to startups selling into high-stakes workflows: biologics, offensive security, federal cloud, and financial services.

What mattered this week

  • AI specialist GPs could still close capital. The two cleanest fund-close signals were Sands Capital’s $1.1B Global Innovation Fund III and Gradient’s $220M Fund 5.

  • Startup money stayed concentrated in mission-critical AI. The week’s notable rounds were not mostly “wrapper” software; they were AI biotech, cybersecurity, federal cloud, and automated research.

  • Quantum’s most important capital event was an exit/liquidity signal. Horizon Quantum completed its dMY Squared combination, started trading on Nasdaq on March 20, and brought in nearly $120M of gross proceeds.
