Three sprawling AI infrastructure initiatives — one anchored by Samsung and SK hynix on the memory and chip side, one led by Blackrock and Microsoft, and the OpenAI-backed Stargate project — have emerged as the defining mega-projects of the global AI buildout. The question of which player acts as the decisive kingmaker among them remains open, with each camp holding different levers over compute, memory, and capital.
Samsung and SK hynix sit at the foundation of every one of these projects. AI datacenters require vast quantities of HBM and conventional DRAM, and the two Korean chipmakers dominate the memory supply that powers GPUs from Nvidia and other vendors. Their capacity allocation decisions effectively determine how fast any hyperscaler can scale its AI fleets, giving the Korean pair leverage that extends well beyond their role as component suppliers.
The Blackrock-Microsoft axis represents the financial and cloud layer of the infrastructure race. Microsoft brings hyperscale datacenter operations and its position as OpenAI's primary cloud partner, while Blackrock channels institutional capital into the physical buildout of AI facilities. This pairing addresses the enormous financing gap that AI infrastructure demands, where single projects can exceed the balance sheets of any one technology company.
Stargate, the OpenAI-aligned initiative, pursues the most ambitious vision: purpose-built AI campuses designed for frontier-scale training and inference. Its success depends on securing GPU supply, memory allocation, and power at a scale no project has attempted before — placing it in direct competition with the Blackrock-Microsoft buildout for the same constrained resources.
The three projects are not strictly rivals but interdependent layers of the same buildout: Stargate needs compute, Blackrock-Microsoft need tenants and returns, and Samsung-SK hynix need demand for their memory. Which party ultimately dictates terms — the chip suppliers, the financiers, or the model developers seeking capacity — has not been definitively settled and will depend on how supply constraints and capital flows evolve.
Taken together, the claim that these three initiatives constitute the AI infrastructure race's defining mega-projects, with the kingmaker role still contested, is Mostly True.
