STACK Infrastructure Plans Major Capacity Expansion at Portland Data Center Campus

According to a recent LinkedIn post from STACK Infrastructure, the company is planning significant capacity additions at its flagship Portland, Oregon data center campus. The post indicates that 25MW of new capacity is expected to be available in Q4 2027, with a further 96MW of expansion capacity anticipated beginning in 2029.

The LinkedIn post highlights that the site has committed power and connectivity to trans-Pacific cables and key West Coast markets, positioning it as a scalable hub in Hillsboro. The post also characterizes the Portland area as one of the nation’s more capacity-constrained data center markets, suggesting that early access to long-dated capacity could be strategically important for hyperscale and large enterprise customers.

For investors, the planned multi-phase expansion points to a long-term growth pipeline in a region with structural supply constraints, which could support higher utilization and potentially favorable pricing dynamics. The focus on connectivity to trans-Pacific routes and major West Coast hubs may enhance STACK Infrastructure’s competitive position with cloud, content, and AI workloads that require both scale and network performance.

However, the extended build-out timeline into 2027 and 2029 underscores that related revenue contributions are likely to be medium to long term rather than immediate. The scale of the planned additions also implies ongoing capital intensity, so eventual returns will depend on securing pre-leasing or anchor tenants and managing construction and power-delivery risks in a tight market.
