①
Power has become the binding constraint
US datacenters are expanding faster than the grid can support, requiring $110 billion in new generation capacity by 2030, prompting 14+ states to impose moratoriums and PJM (the nation's largest grid operator) to warn of 2030 reliability failure. Hyperscalers are responding by locking in long-term power: Google signed a 22-year Fortum agreement, and NOVVA secured a 3.17 GW renewable portfolio.
②
Custom inference silicon is becoming the hyperscaler priority
Meta plans H1 2027 deployment of its Arke chip, Samsung is backing Euclyd's €200M inference accelerator initiative, and Amazon is securing Qualcomm AI chips, as hyperscalers move to escape NVIDIA's scale-dependent licensing costs.
③
Manufacturing bottlenecks are emerging as the next constraint
ASML's EUV lithography tools are stressed beyond current capabilities by advanced AI chip designs, and while ASML forecasts 110+ tools annually by 2028, the surge demand from hyperscaler custom silicon development threatens to exceed production capacity.
