Equinix (EQIX) is not just renting space anymore. It is becoming a key stop on the AI supply chain. That matters. Big tech does not want random data centers. It wants secure, connected, high-performance sites that can handle huge AI workloads.Â
That is where Equinix keeps winning. Its ties with Nvidia and Cisco only sharpen that story. The company recently said it is partnering with Nvidia (NVDA) and Cisco (CSCO) to help deploy secure AI factories across its global network of data centers.Â

Despite this boost, the real question remains. The stock has already had a big run, so the real question is not whether the AI story is real. The question is whether investors are paying too much for it now.Â
The Stock Has Already Done a Lot of Heavy Lifting
EQIX has been strong over the past year. The stock climbed from the low $700s in mid 2025 to about $1,089 in June 2026, a gain of roughly 43.2% year-to-date (YTD). Investors have chased anything tied to AI infrastructure. The big catalyst has been the idea that Equinix is not just benefiting from AI demand, but it is helping shape where that demand lives.
This is where investors need to be careful. Equinix looks expensive on traditional metrics. Its price-to-earnings ratio is 71.54 times, while the broader REIT sector is much lower, closer to 30.45 times. Its EV to EBITDA multiple is 30.21 times, which is also rich versus most peers in the sector at 16.96 times.
That premium can make sense for a company with durable growth and a strong AI position. But it also means the market is already paying up for a lot of good news. This is not a bargain stock. It is a quality stock priced like one.
Nvidia and Cisco Add Credibility to the AI Story
The latest headline is important because it shows Equinix is getting pulled deeper into the AI buildout. Its expanded work with Nvidia, and Cisco is aimed at secure AI factories across its data center footprint. That means Equinix wants to be the place where enterprise AI gets deployed, tested, and scaled.
Investors liked that. The stock popped on the announcement. That reaction makes sense because deals like this validate Equinix’s role in AI infrastructure. They also strengthen its pitch to large customers who want trusted partners, not just raw capacity. The impact is bigger than a one-day move. Rather, it gives Equinix more credibility in front of customers, and more optionality for future service revenue.
