The retreat comes as concerns mount over AI financing costs and rising debt yields. AI-related high yield credit spreads widened 50 basis points to 371 bps, and several AI data center bonds now yield above 10%, according to market data. Goldman Sachs projects $720B in AI project financing and direct hyperscaler debt issuance in 2027, a critical pivot as AI capital expenditure already accounts for approximately 50% of S&P 500 earnings growth. This institutional exodus contrasts with retail investors, who poured a record $7B into the 3x semiconductor ETF SOXL and $1.3B into the 3x Nasdaq ETF TQQQ last week.
