Microsoft shares rise 1.4% as local AI push shifts compute from Azure to desktops

Microsoft shares rose approximately 1.4% to $529.97 on Friday after the company unveiled plans to run AI directly on PCs. The initiative combines local AI models with cloud integration, featuring Microsoft Execution Containers that limit desktop agent access and Copilot technology splitting tasks between device and cloud. The company launched its Surface Laptop Ultra, priced between $2,599 and $5,899. Anthropic, OpenAI and Nvidia plan to adopt the security technology. The move presents a strategic trade-off for Microsoft. Whilst local AI offers faster responses and enhanced data security, it could reduce demand for Azure inference workloads. Success depends on stronger Windows adoption, premium device sales and sustained cloud usage to offset potential Azure revenue impacts.

American tech giants face resistance over $65B data centre expansion in Australia

American tech companies are expanding data centre operations in Australia, but face growing opposition from residents and farmers. Local communities near Melbourne are protesting planned facilities, citing concerns over noise, energy consumption, and water usage. Investment in Australian data centres could exceed $100 billion by 2030, according to the Commonwealth Bank of Australia, with Microsoft and Amazon already committing funding. Companies are attracted by Australia's geographic location, renewable energy access, and democratic stability. However, the expansion faces obstacles. New regulations on water efficiency and power supply take effect next year. Australia's strict copyright protections pose challenges for AI companies seeking regulatory certainty. Recent revelations that an OpenAI agent accessed Australian government websites without authorisation have intensified scrutiny. Experts question whether AI companies should receive special treatment regarding accountability.

Microsoft CEO honored with national medal hours after H-1B visa suspension over foreign worker claims

President Donald Trump presented the National Medal of Technology and Innovation to Microsoft CEO Satya Nadella on Thursday, hours after Vice President JD Vance suspended the company from a programme allowing green card applications for H-1B visa holders. Vance accused Microsoft of replacing 6,000 laid-off American workers with foreign employees, obtaining 6,300 H-1B visas and nearly 3,000 green cards last year. Microsoft, which employs 223,000 people globally, said most H-1B applications were for existing employees. Trump praised Nadella's three-decade contribution to Microsoft's transformation whilst making no mention of the visa controversy. Five of six tech leaders honoured were immigrants, including Elon Musk, Sergey Brin, Jensen Huang, and Lisa Su. Vance maintained the administration would "continue to support Microsoft and have a great relationship" with the company despite the suspension.

Resilinc brings supply chain risk intelligence to Microsoft Copilot

Resilinc has launched a plugin for Microsoft Copilot that integrates supply chain risk and compliance intelligence into Microsoft applications. The tool allows authorised users to ask natural-language questions about supply chain disruptions, suppliers, compliance risks, and regulatory issues, with responses tailored to their organisation's specific data and permissions. The plugin uses Model Context Protocol to connect Resilinc's supply chain graph with Copilot whilst maintaining existing security controls. It builds on Resilinc's collaboration with Microsoft, previously demonstrated at Hannover Messe. The integration supports Resilinc's broader compliance strategy, including recent extensions for the EU Deforestation Regulation. The plugin is available to eligible Resilinc customers through their account teams.
