Microsoft adds 30,000 Nvidia chips to Norway site after $6.2B commitment

Microsoft has secured a deal with neocloud provider Nscale to expand its Norway data centre site with 30,000 Nvidia chips. The agreement adds to Microsoft's earlier $6.2 billion commitment to the location, whilst OpenAI did not finalise a capacity agreement there. The move is part of Microsoft's roughly $60 billion spending wave on specialised neocloud providers that rent AI computing infrastructure. CEO Satya Nadella has identified power availability and data centre construction speed as the company's biggest bottleneck, rather than chip supply. The deal reflects how cheap electricity and clear regulations increasingly shape AI data centre locations. Nscale, a UK-based startup that emerged from crypto-mining firm Arkon Energy in 2024, raised $2 billion at a $14.6 billion valuation in March 2026.

Microsoft takes over $6.2B Stargate data centre from OpenAI in Norway

Microsoft has agreed to rent data centre capacity at a Norwegian site originally intended for OpenAI as part of its Stargate initiative. The company will rent 30,000 additional Nvidia Vera Rubin chips from neocloud provider Nscale at a campus inside the Arctic Circle in Narvik, Norway. The deal builds on Microsoft's prior $6.2 billion commitment at the same location. Nscale announced the agreement in a statement, marking a shift in the facility's intended purpose from OpenAI to Microsoft operations.

Microsoft stock down 23% despite Azure growing 39% and $625B revenue backlog

Microsoft shares have fallen 23.14% year-to-date to $370.87, despite strong Q2 FY2026 results showing non-GAAP EPS of $4.14, a 7.57% beat. Revenue reached $81.27 billion, up 16.72% year-over-year, with Azure growing 39%. The company's commercial remaining performance obligation surged 110% to $625 billion in contracted future revenue, providing multi-year visibility. Microsoft's OpenAI partnership includes a $250 billion incremental Azure services commitment, whilst the company holds a 27% stake valued at approximately $135 billion. Despite the decline, 95% of covering analysts remain bullish, with a consensus price target of $587.31. Analysts cite the year-to-date drop as creating an entry point for investors confident in Azure's AI growth trajectory.

Microsoft hikes UK Surface prices by up to $280 as RAM shortage hits consumers

Microsoft has quietly raised UK prices for its Surface devices by £170 to £220, citing rising memory and component costs. The 13-inch Surface Laptop now starts at £1,099, up from £899 in February, whilst the 15-inch model has increased from £1,349 to £1,519. In the US, some configurations have jumped from $999 to $1,499, according to Windows Central. Microsoft acknowledged the increases are due to rising memory and component costs, as chip manufacturers prioritise high-bandwidth memory production, leaving DRAM and NAND supplies constrained. The changes were not announced; Microsoft simply updated pricing on its website and removed cheaper configurations. The memory shortage is affecting manufacturers across the board, from Chromebooks to Raspberry Pi devices, with geopolitical tensions and freight costs further driving prices higher.
