CNBC reported on September 2 that Equinix, Inc. (NASDAQ:EQIX), a colocation data center company dating back to the 1998 dot-com era, has carved out a role in the AI infrastructure boom despite lacking the profile of hyperscalers or neoclouds.
The company inked an expanded partnership with Nvidia at its inaugural Equinix Horizon event. It launched the Equinix Inference Exchange, which gives enterprise customers a flexible way to run AI models using Nvidia’s Enterprise Reference Architectures and Together AI’s open-source inference platform, delivered through Equinix’s global data centers and connectivity. Equinix operates more than 280 data centers across 77 metros with over 10,500 interconnected customers, and its facilities are optimized for Nvidia’s B300 Blackwell Ultra GPUs, with some liquid-cooled sites supporting newer Vera Rubin chips.
Shares are up over 33% this year, lifting Equinix’s market capitalization to $100 billion, the most valuable data center REIT, ahead of Digital Realty’s $68 billion. Hyperscalers are expected to spend more than $5 trillion on AI infrastructure by 2030, according to Goldman Sachs Research.
Bull Case
Equinix, Inc. (NASDAQ:EQIX)’s latest results support its AI-driven growth story with strong financial momentum. Second-quarter revenue grew 16% to $2.625 billion, AFFO per share rose 19% to $11.78, adjusted EBITDA margin reached a record 53%, and management delivered its largest guidance increase in company history.
Equinix holds a differentiated position in the AI infrastructure market through its extensive global network. The company operates more than 280 data centers and connects more than 10,500 customers, giving it a strong platform for enterprise AI inference without requiring it to compete directly with hyperscalers for the largest training workloads.
Equinix’s expansion strategy also emphasizes returns and customer demand. More than 80% of planned capacity expansion through 2029 targets the company’s strongest 25 global metros, while churn fell to 1.8%, below its historical 2% to 2.5% range. Strong customer retention and targeted expansion could help Equinix capture growing AI demand while maintaining attractive returns.
Bear Case
Equinix, Inc. (NASDAQ:EQIX) plans to spend substantially more to capture the AI opportunity. The company nearly doubled its capital expenditure guidance to $5 billion to $7 billion annually from $3 billion to $4 billion, creating greater financing needs and potential balance-sheet pressure even as management protects its investment-grade credit rating.
The Nvidia and Together AI partnership still needs to prove its commercial value. The announcement builds on an existing relationship, and Equinix expects the new offering to launch commercially in the first quarter of 2027. Investors therefore need to see actual enterprise inference demand translate into meaningful incremental revenue before they can assign significant value to the partnership.
Equinix’s current valuation also leaves limited room for disappointment. The stock has gained 33% this year, while Equinix faces competition from hyperscalers and neocloud providers that spend hundreds of billions of dollars on infrastructure. Equinix therefore needs to sustain strong execution and deliver on its higher guidance to justify its valuation and generate further upside.
Hedge Fund Data
Insider Monkey’s database shows Equinix, Inc. (NASDAQ:EQIX) was held by 73 hedge funds in the second quarter of 2026, up from 65 in the first quarter, with holdings value rising to $6.77 billion from $5.77 billion. Digital Realty, its closest data center REIT rival, matched it at 73 funds, up sharply from just 46, with holdings value nearly tripling to $2.71 billion from $997.7 million. Digital Realty’s much faster percentage growth in both fund count and dollar value suggests hedge funds see more re-rating potential there than in the already highly valued Equinix.
Conclusion
Equinix has built a differentiated position in the AI infrastructure boom through decades of colocation infrastructure and customer relationships, and its latest quarter shows that strategy translating into genuine financial acceleration. The bull case rests on strong current results, a defensible enterprise-inference niche, exceptional customer retention, and a disciplined expansion plan.
The bear case centers on sharply rising capital spending, a muted market reaction pending proof of inference demand, a smaller share of the AI buildout than hyperscalers capture, and a valuation that already assumes strong execution. Whether Equinix’s niche can grow as quickly as the broader AI infrastructure market will determine whether the company’s rally has further room to run.
