HIVE Digital Technologies plans $3.5B AI gigafactory in Toronto

HIVE Digital Technologies just announced what might be the most aggressive pivot in crypto-mining history. The company plans to build a C$3.5B AI gigafactory in Ontario’s Greater Toronto Area, a facility designed to pack over 100,000 GPUs and roughly 320 megawatts of power capacity under one roof.

The market’s reaction was immediate and enthusiastic. HIVE shares surged nearly 30% in after-hours trading following the May 18 announcement, a clear signal that investors are buying the company’s transformation story from Bitcoin miner to AI infrastructure provider.

From mining rigs to GPU farms

The project will be developed through HIVE’s subsidiary BUZZ HPC, which serves as the company’s high-performance computing arm. The facility is being positioned as a “sovereign AI” campus, a term that’s become increasingly popular among governments and enterprises looking to reduce dependence on foreign AI service providers.

That sovereignty angle is not just marketing fluff. It speaks to a growing anxiety, particularly among Canadian and European institutions, about routing sensitive data through US or Chinese cloud providers. A domestic AI campus with serious compute capacity gives enterprises, academic institutions, and government stakeholders an alternative that keeps data within national borders.

Here’s the thing about 320 megawatts of power capacity: that’s enough electricity to power roughly a quarter-million homes. Concentrating that much energy into a single computing facility puts the project squarely in hyperscaler territory, the kind of infrastructure typically associated with names like Google, Microsoft, or Amazon.

For a company with a market cap that’s a fraction of those tech giants, the ambition is striking. Over 100,000 GPUs at full buildout would make this one of the largest dedicated AI compute facilities in Canada, and one of the more significant private AI infrastructure projects in North America.

The Bitcoin miner exodus to AI

HIVE’s pivot is not happening in a vacuum. It’s part of a broader migration among Bitcoin miners who have realized that the same core competency, securing massive amounts of cheap power and managing high-density computing hardware, translates surprisingly well to AI workloads.

The economics tell the story. Bitcoin mining margins have been under pressure, particularly since the most recent halving event, which cut block rewards in half and forced miners to find new revenue streams or face shrinking profitability. Meanwhile, demand for GPU compute capacity has been surging, driven by the AI training and inference boom that shows no signs of slowing down.

Several former mining-focused companies have made similar moves in recent years. Core Scientific pivoted toward hosting AI workloads. Iris Energy expanded its data center footprint to accommodate high-performance computing clients. The playbook is becoming familiar: take your power contracts, your cooling infrastructure, and your operational expertise in running thousands of machines, then swap out ASICs for GPUs.

What distinguishes HIVE’s announcement is the sheer scale. C$3.5B is not a toe-in-the-water experiment. It’s a declaration that the company sees its future primarily in AI infrastructure rather than cryptocurrency mining.

What this means for investors

The 29.74% after-hours jump tells you the market is excited. But excitement and execution are very different things, and a project of this magnitude comes with substantial risks that deserve careful consideration.

First, there’s the funding question. C$3.5B is a massive capital commitment for a company of HIVE’s size. The announcement didn’t detail exactly how the project will be financed, whether through equity raises, debt, partnerships, or some combination. Investors should watch closely for details on the capital structure, because dilution risk is real when smaller companies pursue mega-projects.

Second, there’s the competitive landscape. HIVE won’t be building this facility in a vacuum. The AI infrastructure market is attracting enormous capital from every direction, from hyperscalers expanding their own capacity to private equity firms backing new data center developments. By the time the Toronto gigafactory reaches full buildout, the supply-demand dynamics for GPU compute could look very different than they do today.

Third, there’s the timeline factor. Large-scale data center projects typically take years to complete. Power procurement, permitting, construction, and equipment sourcing all introduce execution risk. The 320 MW power figure represents full buildout capacity, which likely means the facility will come online in phases.

The sovereign AI thesis is the most interesting angle for long-term investors. If Canadian government agencies and regulated industries increasingly mandate domestic data processing, a facility like this could command premium pricing compared to generic cloud compute. That’s the kind of structural advantage that would justify the valuation premium the market is already assigning to the stock. Whether HIVE can actually deliver on a project of this scale, given its roots as a mid-cap Bitcoin miner, remains the central question investors will need to answer for themselves over the coming quarters.
