AT AMAZON'S BIGGEST DATA CENTER, EVERYTHING IS SUPERSIZED FOR AI

Amazon's Project Rainier involves building data centers so large they would have been considered absurd just a few years ago. The tech industry requires massive networks of specialized computer chips for its increasingly powerful AI technologies. Over the next several years, Amazon plans to build around 30 data centers at a 1,200-acre stretch of farmland outside New Carlisle, Indiana. The entire complex, which will consume 2.2 gigawatts of electricity, will form one giant machine intended just for artificial intelligence. Project Rainier will also include facilities in Mississippi and possibly other locations like North Carolina and Pennsylvania.

BITCOIN DOMINANCE REBOUNDS TO 62% AS INSTITUTIONS FAVOR BLUE-CHIPS

Bitcoin's market dominance has climbed back to 62%, reversing May's dip and signaling sustained institutional preference for blue-chip crypto exposure.
