AI Drives Markets as Valuations Race Ahead of Earnings

Why It Matters

The AI‑driven rally is reshaping capital allocation and risk profiles across major markets, but inflated valuations could trigger a sharp correction that would reverberate globally.

Key Takeaways

• Magnificent Seven contributed ~80% of S&P 500 Q1 earnings growth
• AI‑related IPOs raised ~US$59 billion in China Q1
• Nvidia’s data‑centre revenue gap implies $600 billion unmet application demand
• Hong Kong AI listings posted 37% average first‑day gain in Q1
• Deutsche Bank survey: 57% of investors fear AI valuation collapse by 2026

Pulse Analysis

Artificial intelligence has become the primary growth engine for equity markets, eclipsing traditional macro drivers. In the United States, the S&P 500’s record climb is almost entirely powered by the Magnificent Seven, whose combined earnings surge lifted the index by nearly 30% from its 2025 low. This concentration creates a fragile market structure where a shift in sentiment toward any of these firms could reverberate across the broader index, prompting investors to scrutinize the sustainability of AI‑linked earnings.

Valuation metrics reveal a tension between robust profit margins and speculative pricing. While the leading AI firms post median net profit margins close to 30%, the Shiller CAPE ratio has surged to historic levels of 39‑40, a range only seen before the 2000 dot‑com crash. Analysts point to a $600 billion gap between Nvidia’s projected data‑centre revenue and the application‑side earnings needed to justify current market caps, highlighting the risk that a portion of the AI hype may be priced in ahead of tangible demand.

Across the Pacific, China and Hong Kong are amplifying the AI narrative through policy‑driven listings and venture‑capital inflows. Regulatory reforms on the ChiNext board have opened doors for unprofitable hard‑tech firms, while Hong Kong’s IPO pipeline delivered average first‑day gains of 37% in Q1, reflecting strong investor appetite. However, the rapid influx of capital raises concerns about overextension, as many startups prioritize fundraising over product viability. For global investors, the dual dynamics of a concentrated U.S. rally and an expanding Asian hard‑tech market present both opportunities and heightened exposure to a potential AI valuation correction.
