Amazon shares were up 1.84% at $264.22 Wednesday, outperforming alongside the broader mega-cap technology sector. The move followed the U.S. Treasury Department’s surprise plan to double maximum buybacks of long-term government bonds to $4 billion per operation starting Sept. 9. By absorbing long-term Treasurys and easing yield pressures, the action may improve the interest-rate backdrop for high-growth technology companies. Lower long-term yields reduce the discount rate used in discounted cash flow models, potentially increasing the present value of Amazon’s far-dated, high-margin AI cash flows, while also lowering corporate borrowing costs and easing consumer credit conditions. Amazon’s AWS business is adding further support, with enterprise demand for generative AI capacity described as explosive and infrastructure expansion estimated at 6 gigawatts in 2026 to support workloads including SpaceXAI’s newly added Grok 4.6 model on Amazon Bedrock.
