AI Infrastructure Spending Strains Sovereign Debt Markets and Raises Bubble Risk

Rising government borrowing costs and Treasury intervention linked to the AI boom. ING estimates AI contributes ~36% to US GDP growth, but infrastructure spending is straining fiscal conditions. A new analysis draws parallels to historic bubbles (railroads, dot-com, mortgage mania), highlighting circular financing and overcapacity risks in the $500B compute infrastructure platform, which is framed as opaque asset-backed lending. This adds a dual-correction risk if monetization falters, making macro signals critical for quant and fintech audiences.
