A single firm just vacuumed up 18% of all venture capital dollars allocated in the United States in 2025. Andreessen Horowitz (better known as a16z) has announced it's raised a staggering $15 billion in new capital. This haul brings the organization's assets under management (AUM) to over $90 billion, putting it neck-and-neck with Sequoia Capital as the world's most dominant venture powerhouse.

The massive influx of capital is strategically divided across five distinct funds. The largest portion, $6.75 billion, is dedicated to growth investments. Applications and infrastructure each received $1.7 billion, while biotech and healthcare garnered $700 million. Notably, $1.176 billion has been funneled into 'American Dynamism,' a practice focused on reindustrializing America through defense and manufacturing.

From Riyadh to Mar-a-Lago: The Influence Nexus

The firm's influence is no longer confined to Sand Hill Road. Co-founder Marc Andreessen has become a fixture at Mar-a-Lago since Donald Trump's 2024 victory. He's reportedly serving as an 'unpaid intern' for Elon Musk's Department of Government Efficiency (DOGE), vetting candidates for top Pentagon and intelligence roles. This political capital is matched by financial ties to Saudi Arabia's Sanabil Investments, with Ben Horowitz publicly praising the Kingdom as a 'startup country.'

High-Stakes Bets on Defense and the AI Stack

a16z's current strategy is heavily weighted toward national interests. Their portfolio includes autonomous defense leader Anduril, military drone maker Shield AI, and hypersonic missile developer Castelion. On the AI front, they've positioned themselves across the entire stack, holding stakes in OpenAI, xAI, and Mistral AI. As Horowitz puts it, they're ensuring America wins the 'next 100 years of technology.'
