Trump regulation puts AI data centers on alert; costs could jump if Chinese equipment is blocked

The U.S. boom in building AI data centers is heightening supply-chain risks tied to reliance on Chinese power and optical communications equipment. If Washington tightens restrictions on national security grounds, shortages and higher costs could slow data center construction. Key components such as transformers, switchgear, batteries and optical transceivers depend heavily on China, while existing supply shortfalls for power equipment are already emerging, with limited near-term substitution capacity.

OpenAI on alert ahead of Astra launch as researchers warn of AI safety disaster

OpenAI is strengthening safety measures ahead of the launch of its next-generation AI model, Astra, amid concerns that the model’s internal reasoning could be less visible than in existing systems. OpenAI has delayed parts of development and rollout by several weeks to bolster protections against cyber misuse and unauthorised behaviour. Researchers say reduced visibility into “chain-of-thought” reasoning could make it harder to detect risky actions, while OpenAI says it is adding monitoring and limiting use of certain techniques.

U.S. power grid key equipment \'transformer\' in short supply; import reliance 80 percent, lead times up to 5 years

The U.S. hydropower industry is struggling to replace and upgrade equipment due to difficulties procuring large power transformers, a report said. The analysis by the National Renewable Energy Laboratory identified nine key issues, including about 80 percent import reliance for critical raw materials and limited global capacity for ultra-high-voltage transformers. Lead times range from 2.5 to 3 years and can reach 5 years, while prices have risen about 80 percent since 2021.
