Core conclusion · Tlines extraction
SMBC Nikko's report 'AI capex' assesses the macro impact of hyperscaler AI infrastructure spending. Although hyperscaler capex is projected to exceed $770bn in 2026 and $1.3trn in 2027, the GDP effect is dampened by high import intensity. Nevertheless, the spending significantly influences capital markets, with hyperscalers accounting for roughly 40% of net IG debt supply and contributing to widening credit spreads.

Key arguments
- Hyperscaler capex expected to reach $770bn in 2026, doubling from last year, and exceed $1.3trn in 2027.
- Due to high import share (75% for computers/peripherals), net contribution of AI spending to GDP growth since 2025 is only 15%.
- Hyperscalers account for ~40% of net IG debt supply in 2026 despite being only 5% of IG market.
- Borrowing costs for hyperscalers have risen ~30bp relative to Treasuries, while peer spreads were unchanged, indicating market strain.

Main risks
- AI capex may strain market capacity, leading to further spread widening or crowding out other issuers.
- Potential for AI investment to disappoint if revenue growth fails to materialize, triggering a correction.
- GDP impact could be even smaller if more spending is imported or intermediate.
- Regulatory changes or shifts in AI demand could alter capex plans.
