I’m sounding the alarm (Ad)

Meta is cutting 10% of its workforce. Microsoft offered voluntary retirement to 7% of U.S. employees. Oracle, Amazon, Snap, and Block have done the same. Most assume this is about AI - but investor Porter Stansberry says the real driver runs far deeper. Goldman Sachs estimates 12,400 Americans are being financially harmed every day by this shift, while others grow wealthier. Stansberry - who predicted the internet economy's rise and recommended Amazon, Qualcomm, and Texas Instruments before they were household names - is now releasing a new investigation he calls The Final Displacement.tc pixel

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
