Andreessen Horowitz, one of the world's most influential venture capital firms, has successfully closed a $15 billion mega-fund. This substantial capital raise underscores the firm's ambitious dual focus on blockchain infrastructure and security technologies.

The strategic pivot toward infrastructure development signals growing institutional confidence in Web3's foundational layer. By channeling resources into decentralized infrastructure, the firm is positioning itself at the intersection of technological innovation and market maturation. Meanwhile, the emphasis on defense-oriented investments reflects broader industry concerns about security resilience and protocol robustness.

This $15 billion commitment demonstrates how major capital players are doubling down on ecosystem-level solutions rather than individual tokens. The infrastructure and defense verticals represent critical gaps where capital deployment can unlock tangible developer ecosystem growth and user trust.
