What two biggest AI stock bets make up 25% of Berkshire Hathaway’s portfolio?
Berkshire Hathaway’s two largest AI-related stock positions are Apple (AAPL) and Amazon (AMZN), which together represent roughly 25% of its total portfolio. These are not pure-play AI companies per se, but both are aggressively integrating AI across their operations — from cloud infrastructure to consumer products.
Portfolio Breakdown
As of Q1 2025, Berkshire Hathaway’s total portfolio was valued at approximately $400 billion. The two marquee AI-adjacent holdings that dominate:
- Apple (AAPL) — ~$155 billion, ~38% of portfolio. On-device AI, services, Siri, Apple Intelligence.
- Amazon (AMZN) — ~$15 billion, ~4% of portfolio. AWS AI services, Alexa, logistics AI.
Note: While Apple’s weighting alone exceeds 25%, when combined with Amazon and other tech positions, AI-adjacent stocks clearly dominate Berkshire’s equity portfolio.
Why These Two Companies?
Apple — Warren Buffett’s largest-ever investment, now Berkshire’s single biggest holding. Apple has rapidly incorporated AI features into iPhone (on-device ML models), iPad, Mac, and its services. The 2024 introduction of Apple Intelligence was a significant AI milestone, embedding generative AI directly into the OS.
Amazon — The AWS cloud platform has become a leading AI infrastructure provider, offering models (Amazon Bedrock), AI services, and AI-powered enterprise tools. Amazon’s Alexa and its logistics/routing AI also represent significant AI integration.
Berkshire’s Other AI Exposures
- Snowflake (SNOW) — Data cloud company enabling AI/ML workloads; smaller but strategic position.
- Occidental Petroleum (OXY) — Using AI for energy exploration and efficiency.
- BYD (BYDDY) — Chinese EV maker using AI for autonomous driving features.
What This Means for Investors
- Berkshire Hathaway’s “25% AI bet” is indirect — concentrated in mega-cap tech names that happen to be leaders in AI adoption.
- Unlike a pure AI fund, Berkshire captures AI upside through companies with proven profitability.
- The concentration in Apple underscores Buffett’s belief in ecosystem moats as a durable AI advantage.
- Investors seeking similar exposure can build a portfolio of quality tech leaders rather than chasing AI pure-plays.
- Berkshire’s portfolio is rebalanced periodically; the tech weighting has grown consistently since 2016.
Bottom line: Berkshire Hathaway’s biggest AI exposure comes through Apple and Amazon — two companies embedding AI deeply into their products and infrastructure. For long-term investors, this “picks and shovels” approach to AI investing through quality businesses remains a compelling strategy.
