# Why Uranium (URNM) rose 3.01% on September 3, 2026

Uranium (URNM) rose 3.01% on September 3, 2026 — Big Tech's SMR deals cement nuclear power demand.

## What happened

Big Tech companies (Microsoft, Google, Amazon, others) signed multi-decade power purchase agreements for Small Modular Reactors (SMRs), cementing nuclear as a long-term AI energy solution.

## Why it moved

Long-term SMR contracting converts nuclear into a structural capex story rather than a cyclical bet; sustained multi-decade commitments anchor uranium demand and support mining and fuel cycle expansion.

## Why it matters

Within the AI Power & Energy theme, nuclear is now locked into the hyperscaler capex cycle — SMR deals prove that data-center operators view nuclear as non-negotiable for reliable, low-carbon power at scale.

## What would break the thesis

If the SMR deals prove non-binding or construction timelines slip materially beyond expectations, the demand visibility collapses; regulatory or construction delays are the key invalidator.
