Sources: 6. Developments: 2. The rapid expansion of artificial intelligence is creating significant supply chain pressures across the semiconductor industry. Intel has reported a manufacturing bottleneck where demand for data center and AI chips is outpacing factory output. To address shortages in server processors and rising capital needs, the company has increased its 2026 capital spending projections to over $20 billion and initiated a $20 billion stock offering. Simultaneously, the demand for AI data centers is driving a surge in prices for indium phosphide (InP) substrates, which are essential for manufacturing lasers used in optical modules for ultra-fast data transmission. Prices for InP wafers have risen sharply in China, with analysts predicting further increases. In response to this supply crunch, Japanese producer JX Advanced Metals has announced plans to invest approximately $752 million over four years to expand production. ## Timeline ### 2026-08-17: Indium phosphide prices surge due to AI data center demand Demand for indium phosphide, a critical material for AI data center optical transmission, is causing significant price spikes and supply chain pressures in China and Japan. 3 sources. https://clstr.news/cluster/indium-phosphide-prices-surge-due-to-ai-data-center-demand ### 2026-08-14: Intel faces supply shortage as data center demand exceeds output Intel faces a supply crunch as data center and AI chip demand outpaces manufacturing capacity, prompting a $20 billion capital spending increase for 2026. 3 sources. https://clstr.news/cluster/intel-faces-supply-crunch-as-data-center-demand-outpaces-output --- Cite as: AI data center demand driving semiconductor supply shortages.
