Why The Biggest Names in AI Are Heading To The Arctic (Ad)

Google contracted over 12 GW of energy last year and just announced a 15 billion dollar AI infrastructure investment in Finland. Cerebras followed with plans for a 165 MW data center worth up to 1.7 billion euros. One small Nasdaq-listed company built its Nordic footprint before this wave hit, with up to 190 MW of capacity approaching ready-for-service status in 2027 to early 2028. Recent long-term data center deals have valued capacity at 1.7 to 2 million dollars per MW annually. See why this overlooked company could be next in the AI infrastructure spotlight.tc pixel

Ominous New Day in America (Get Ready for it) (Ad)

A market forecaster with a 55-year track record - including calls on 1970s double-digit inflation, the 1980s S&L collapse and Black Monday crash, and the 2000s dot-com bust and Lehman Brothers collapse - says a major shift is coming to how Americans bank, work and insure themselves. The New York Times has credited him as the first to spot looming dangers, and he has testified before Congress on past financial crises.tc pixel
