Microsoft will invest $4 billion

Microsoft, the American software and cloud services company, plans to invest an additional $4 billion over the next three years to build a second artificial intelligence data center in the state of Wisconsin.
With this new investment, Microsoft would increase its spending to more than $7 billion in Wisconsin, including what is required for the installation of the Fairwater AI data center.
The new data center, scheduled to open in early 2026, will be equipped with hundreds of thousands of NVIDIA graphics processing units, designed to deliver 10 times the performance of today's fastest supercomputers.
Mexican company Skysense announced on Thursday a $110 million investment plan for the remainder of this year and through 2026, which it said will be used to promote microgrid, solar energy, and battery storage projects.
The company seeks to consolidate its role as a long-term strategic partner in the energy transition of companies in Mexico and Latin America, accelerating the transformation process to a more competitive, resilient, and sustainable energy model in the region, it said in a statement.
Skysense, which serves airport, industrial, real estate, and hotel groups, offers energy services to large energy consumers and generators to optimize costs, reduce emissions, ensure operational continuity, and address power quality challenges.
Chinese artificial intelligence developer DeepSeek said it spent $294,000 training its R1 model, a figure far less than its US rivals, in a report likely to reignite debate over Beijing's place in the race to develop AI.
The Hangzhou company's rare update—its first public estimate of R1's training costs—appeared in a peer-reviewed paper in the academic journal Nature published Wednesday.
The January release of what DeepSeek believed to be low-cost AI systems triggered a plunge in technology stocks among global investors, who feared the new models would threaten the dominance of AI leaders like NVIDIA.
