This year's 26% AI rally is considered more durable than previous surges because valuations, despite reaching new highs, remain below their peak levels. AI has been among the top-performing thematic indexes this year, driven largely by semiconductors and hardware companies. The Bloomberg AI Index (BAIAET), comprising 121 companies, has gained 26% year-to-date, outperforming the Magnificent Seven, World Equity Index, and World Tech Index. Bloomberg analysts anticipate generative AI revenue to hit $2.3 trillion by 2032, providing a powerful boost across the entire AI ecosystem.
Despite a pullback in the first quarter, AI stocks rebounded sharply, with European AI stocks leading with a 42% return, followed by North America at 35%, and Asia Pacific at 23%. Top-performing companies include Applied Optoelectronics, Seagate, Intel, and SK Hynix, each reporting gains over 190%. Fundamentals remain strong, with estimated earnings growth of 37% year-over-year for 2026. The EV-to-sales multiples for the AI theme are 21% below their December 2024 peak, suggesting a sharper valuation reset compared to the broader tech market.
Corporate spending continues to fuel the AI growth story, with global data center capital expenditures expected to surpass $1 trillion in 2026. Hyperscale cloud providers are aggressively investing in data centers, networking equipment, power infrastructure, and accelerator deployments. Amazon, Alphabet, Microsoft, and Meta alone are projected to spend a combined $750 billion this year on AI infrastructure, an 80% increase from 2025. This significant capital outlay is increasingly being financed through debt, making these tech giants more susceptible to interest rate fluctuations and monetary policy, a shift from their traditional cash-rich operations.
