SpaceX eyes a 1.75 trillion valuation - here's what to know (Ad)

Elon Musk's team has quietly filed confidential paperwork with the SEC for what Bloomberg estimates could be a $1.75 trillion IPO - larger than Saudi Aramco and any tech offering in history. CNBC calls it 'the big market event of 2026.' According to former tech executive and angel investor Jeff Brown, there's a way to claim a stake before the public filing drops, starting with as little as $500.tc pixel

Goldman Sachs just told you what to buy (most people missed it) (Ad)

Goldman Sachs just revealed that 40% of AI data centers will be crippled by electricity shortages by 2027 - not chips, not funding, but power. Demand is growing 15% per year and the grid can't keep up. One small company makes the exact equipment these data centers need. They're sitting on $1.5 billion in orders, their hardware is already inside Musk's Colossus, and the stock still trades like a name nobody's heard of. Analyst Dylan Jovine is releasing the ticker for free.tc pixel
