Semper Augustus Investments Group: 2025 Annual Letter

Why It Matters

The letter signals a fundamental shift in where investors should deploy capital, emphasizing AI infrastructure over conventional equity expectations and reaffirming Berkshire Hathaway’s benchmark status for value‑focused portfolios.

Key Takeaways

• AI and datacenter spending now exceeds $1 trillion annually
• S&P 500 likely underperforms historic Ibbotson returns
• Value investing faces a secular plateau in 2020s
• Bloomstran presents unprecedented calculation comparing AI costs
• Berkshire Hathaway remains top long‑term capital allocator

Pulse Analysis

The AI and datacenter boom has moved beyond hype into a trillion‑dollar funding cycle, compelling investors to reassess traditional asset allocations. Bloomstran’s 2025 letter quantifies this shift, highlighting that cloud providers, chip manufacturers, and edge‑computing firms are absorbing capital at a scale comparable to the early‑2000s telecom surge. This influx not only inflates valuation multiples but also creates a new competitive frontier where speed of deployment and energy efficiency become decisive factors for long‑term returns.

Concurrently, the letter dismantles the comforting narrative that the S&P 500 will continue delivering the historic Ibbotson real‑return of roughly 7% per year. By juxtaposing projected AI‑driven capex with historical earnings growth, Bloomstran argues that the equity market is entering a secular plateau, where growth stocks lose their premium and value investors must navigate a narrower moat. This perspective urges portfolio managers to diversify into sectors that directly benefit from AI infrastructure, such as specialized hardware, renewable power for data centers, and niche software platforms, while tempering expectations for broad‑market equity performance.

Finally, Bloomstran’s deep dive into Berkshire Hathaway serves as a counterpoint to the AI‑centric narrative, reinforcing the timeless appeal of disciplined capital allocation. He points out that Berkshire’s decentralized operating model, strong cash generation, and strategic acquisition discipline remain unmatched, offering a hedge against the volatility of AI‑heavy investments. For value‑oriented investors, the Berkshire analysis underscores the importance of pairing innovative exposure with proven, resilient business models to achieve sustainable, long‑term wealth creation.
