AI Bubble Risks Worst S&P 500 Crash Since 2008, Strategist Says
Joachim Klement says hyperscalers’ depleted cash flows and rising borrowing costs could end the AI trade, leaving the S&P 500 36% below current levels.
- Panmure Liberum strategist Joachim Klement warned the artificial intelligence trade could end as soon as 2027, potentially triggering a severe market crash. "My core conviction is that the AI bubble will either burst in 2027 or in 2028," Klement said.
- Klement's outlook shifted due to concerns that stubborn inflation and rising borrowing costs could derail AI-related infrastructure spending. Bloomberg Intelligence estimates hyperscalers' capital spending in 2026 could hit $713 billion.
- Projections indicate equities could face 36% downside from current levels by 2027, while The Stoxx may fall more than 30%. These forecasts are the most bearish among Bloomberg-tracked strategists.
- Rather than advising clients to sell now, Klement suggests developing contingency plans and timing tools. His number one recommendation is "to go full defensive" once equities drop below the benchmark's 200-day moving average.
- Temasek International's chief investment officer Rohit Sipahimalani warned earlier in October that a reversal of the AI trade remains a key risk, even as Citigroup strategists remain optimistic that solid 2027 earnings will support further gains.
