Startup investors showed strong activity in May by backing key companies with large sums of money.

They focused on fewer but bigger deals rather than spreading capital widely.

Mega Rounds Signal Shift to AI and Defense Leaders

Andreessen Horowitz and General Catalyst led the pack by guiding six rounds each as lead investors.

One standout deal saw Andreessen Horowitz co-lead a five billion dollar round for defense startup Anduril.

General Catalyst helped back a one billion dollar round for artificial intelligence company Cognition.

Highest spending investors joined a massive round for Anthropic that highlighted the pull of top artificial intelligence players.

For everyday people this means faster progress on technologies that could transform jobs healthcare and security in the coming years.

Overall the data points to a maturing market where big players set the pace for the entire ecosystem.
