5. HIVE Digital Technologies Ltd. (NASDAQ:HIVE)

Market Capitalization: $952.48 million

Number of Hedge Fund Holders: 14

HIVE Digital Technologies Ltd. (NASDAQ:HIVE) is one of the best small cap data center stocks to buy. On May 8, HIVE announced that its wholly owned subsidiary, BUZZ High Performance Computing, has contracted a new fiber optic network overbuild and an upgrade of the carrier transport network at its Grand Falls Data Center in New Brunswick.

The company said the estimated capital commitment from HIVE will be approximately $3.1 million for a period of five years. HIVE emphasized that this is a critical infrastructure step to advance the HIVE New Brunswick campus to a Tier III HPC-enabled data center.

Currently, Grand Falls is already energized at 70 MW gross load, HIVE noted, adding that buildings and core electrical infrastructure are in place. It added that BUZZ is converting the site into a 50 MW Tier III+ AI factory designed for enterprise, government, and sovereign AI workloads.

HIVE and BUZZ Executive Chairman Frank Holmes emphasized that AI is the new industrial race. He added:

“Countries that build sovereign AI factories will raise their productivity and security through data sovereignty, ensuring data doesn’t leave the countries’ borders, providing those nations greater data IQ. Countries that do not have their own sovereign AI infrastructure will depend on foreign infrastructure and thus rent intelligence from others.”

Holmes said the fiber overbuild is the superhighway that moves that intelligence to customers. He further said:

“Power plus fibre plus GPUs equals an AI factory. New Brunswick has the chance to become one of Canada’s most important AI infrastructure hubs. We are flourishing in the AI token economy, and our vision is to consume electrons and export tokens. The vision is to turn Canadian power into Canadian AI tokens of intelligence.”

HIVE Digital Technologies Ltd. (NASDAQ:HIVE) builds and operates next-generation Tier-I and Tier-III data centers across Canada, Sweden, and Paraguay, serving both Bitcoin and high-performance computing clients. The company’s twin-turbo engine infrastructure, driven by hashrate services and GPU-accelerated AI computing, delivers scalable, environmentally responsible solutions for the digital economy.

4. Bit Digital (NASDAQ:BTBT)

Market Capitalization: $589.47 million

Number of Hedge Fund Holders: 18

Bit Digital (NASDAQ:BTBT) is one of the best small cap data center stocks to buy. Despite posting lower revenues in the first quarter of the year, Bit Digital remained firm on its Ethereum-focused strategic asset game plan, which is centered on treasury management, staking, and disciplined capital allocation, the company said on May 14.

Bit Digital Chief Executive Officer Sam Tabar expressed optimism for the convergence of Ethereum and AI, emphasizing that Ethereum infrastructure and AI compute infrastructure are components of a single integrated platform aligned with the future of the digital financial system. He added:

“Ethereum infrastructure will become increasingly important to the future digital financial system as stablecoins, tokenization, and on-chain settlement activity continue scaling globally. The future financial system will increasingly revolve around automated, on-chain value transfer between AI agents and applications — Ethereum is particularly well-positioned to serve as the settlement layer for that activity.

Bit Digital sits at both layers of this thesis: providing the compute infrastructure through WhiteFiber and the settlement rails through our Ethereum treasury and staking platform. Demand for compute and power continues exceeding available supply across AI infrastructure markets, and compute itself is scarce and valuable enough to become a new asset class.”

Bit Digital (NASDAQ:BTBT) is a strategic asset company focused on active participation in Ethereum infrastructure and controlling equity exposure to AI/HPC infrastructure through its majority ownership stake in WhiteFiber.

Clearfield, Inc. (NASDAQ:CLFD) is one of the best small cap data center stocks to buy. On May 12, Clearfield Inc. President and CEO Cheri Beranek said the company expects to begin shipping the newly introduced NOVA platform in the third or fourth quarter of the year.

“And so, we really have received a strong open door welcoming from the data center community, and we expect that we’ll start to see the Nova platform business in the third and fourth quarter.”

In January, Clearfield announced the launch of the NOVA Platform, a modular, high-density fiber ecosystem designed to make building and scaling modern networks more intuitive. The company explained that the platform is engineered for a range of environments, such as large hyperscale and co-location data centers, offering space-efficient solutions that can evolve as quickly as their capacity demands.
