AI Data Centre Delays Put Equinix Stock And Digital Realty Shares In Focus

AI data centres were sold as the next gold rush, yet delays, spiralling build costs and community pushback are now testing that story in real time. When sentiment swings this hard, mispricing often follows, creating room for both opportunity and regret. This article explains how the latest US setbacks affect smaller US and UK listed developers, and identifies three stocks most exposed to this news shock.

The three stocks in the spotlight below are only a sample. The full screen surfaced 17 more highly leveraged AI data centre and neocloud developers with equally compelling narratives that are not covered here. To identify and analyze those extra candidates straight away, head into the Highly Leveraged AI Data-Centre & Neocloud Developers screener.

Equinix (EQIX)

Overview: Equinix runs global data centres and colocation hubs that host AI and cloud infrastructure, giving enterprises fast, reliable digital connectivity worldwide.

Operations: Equinix generates about US$9.9b from designing, building out and operating IBX data centres, with key markets across the US, EMEA and Asia-Pacific.

Market Cap: US$97.3b

Equinix matters for this screener because it sits at the scale end of AI data-centre buildouts, where power, debt and hyperscaler demand collide most visibly.

"Equinix plans to invest US$5b to US$7b per year in development from 2027 to 2029, targeting low to mid 20% cash on cash returns with 2 to 3 year stabilizations, which, if achieved, could support higher revenue and AFFO growth than currently reflected in the stock."

What happens to that equation if a single unseen pressure quietly squeezes the cushion between project build costs and future returns?

If that squeeze worries you, read the full narrative for Equinix to see how Equinix’s build plan, leverage and AI demand story could be decoupling from first impressions.

Digital Realty Trust (DLR)

Overview: Digital Realty Trust runs a global network of data centres where enterprises and cloud providers colocate critical infrastructure and interconnect for AI and broader digital workloads.

Operations: Digital Realty Trust generates about US$6.8b from commercial REIT activities, with roughly US$3.6b in the United States and US$3.2b from other regions.

Market Cap: US$66.5b

Digital Realty Trust matters for this highly leveraged AI data-centre and neocloud theme because it links power-hungry tenants to dense connectivity hubs. At the same time, it relies on heavy development spending and debt markets to keep new campuses coming online.

"Digital Realty's record signed but not yet commenced lease backlog of about US$1.9b, plus a further US$410m of hyperscale leases signed in July, points to a large pipeline of contracted revenue that has not yet flowed through earnings and could support future core FFO per share."

The real test for Digital Realty Trust is what happens to margins and growth if one key funding assumption quietly stops working in its favour.

If that funding hinge keeps you thinking, read the full narrative for Digital Realty Trust to see whether Digital Realty Trust’s backlog is quietly masking risk or accelerating upside.

Applied Optoelectronics (AAOI)

Overview: Applied Optoelectronics designs and manufactures high speed fiber optic modules and lasers that connect AI focused internet data centres globally.

Operations: Applied Optoelectronics generates about US$596 million from optical networking equipment, with roughly US$296 million from Taiwan and US$280 million from China.

Market Cap: US$6.8b

Applied Optoelectronics matters for this screener because it supplies the high speed optical links that AI heavy data centres need, without carrying the same project financing and construction risk that is now hitting developers directly.

"The recent first volume order for 1.6T transceivers from a major hyperscale customer in March 2026, reportedly over US$200M, with shipments expected in 2H26."

What happens to this set up if a single unseen pressure quietly shifts the balance between that demand surge and future pricing power?

That pricing squeeze is exactly what the full narrative for Applied Optoelectronics unpacks, separating one-off hype from an accelerating multiyear story that could reshape Applied Optoelectronics’ risk-reward mix.
