The chokepoint supplier behind SpaceX's $1.75 trillion empire (Ad)

When Musk laughed and said 'you need transformers to run transformers,' it wasn't a joke - it was a confession. The world's largest supercomputer requires power equipment that takes 120 weeks to build, and Musk built Colossus in just 122 days. One small American company is positioned to close that gap faster than anyone else, yet Wall Street still prices it like an afterthought. Dylan Jovine has the full story and the ticker.tc pixel

Trump's gold order: the announcement they won't put on the front page (Ad)

On August 15, 1971, Nixon interrupted prime-time television and ended the gold standard in 15 minutes - no debate, no vote, one executive order. Gold tripled within three years and climbed 20x over the following decade. Trump holds that same executive authority today, and his advisors are openly saying a reversal is on the table. There are two ways this plays out - both move gold in the same direction. A free briefing breaks down exactly what Nixon did, why Trump is positioned to act, and how to move your 401k into gold before any announcement - tax free.tc pixel
