Simplify's Take

What believers are saying

  • January 2026 fundraising captured over 18% of U.S. venture dollars.
  • Speedrun SR007 runs in San Francisco through October 11, 2026, feeding proprietary deal flow.
  • Crypto Fund 5’s $2.2 billion launch targets stablecoins, RWA, and on-chain finance.

What critics are saying

  • Coinbase’s January 30, 2026 derivative suit survived, extending Andreessen fiduciary scrutiny.
  • The ai16z and ElizaOS lawsuit weaponized a16z’s brand, exposing reputational spillover across crypto.
  • If crypto regulation tightens after 2026 prediction-market fights, a16z’s largest crypto bets face compression.

What makes Andreessen Horowitz unique

  • January 2026: raised over $15 billion across five funds, including $6.75 billion growth.
  • Speedrun backs up to $1 million per company and has funded 250 startups.
  • Marc Andreessen and Ben Horowitz still brand a16z as a founder-first, full-lifecycle platform.

Tech billionaires pour $3B into Berkeley AI mining firm hunting data centre materials

OpenAI co-founder Sam Altman and fellow billionaires Jeff Bezos, Bill Gates and Mark Zuckerberg are investing in Berkeley-based KoBold Metals, which uses artificial intelligence to find critical minerals for data centres and electric vehicles. The company, valued at nearly $3 billion, is now the second-most valuable tech firm in Berkeley. KoBold employs AI to locate copper, lithium, nickel and cobalt deposits. In April, it broke ground in Zambia on what may be one of the world's largest copper deposits, one of 60 projects across 14 countries. The firm has also announced the largest lithium exploration in history in the Democratic Republic of Congo, spanning 3,000 square kilometres. However, some mining executives question whether KoBold's technology truly discovered the Zambian deposit and highlight technical challenges in extracting ore from deep underground. The Trump administration has supported KoBold's operations through foreign policy initiatives aimed at securing US access to critical minerals.
