The cat is out the bag (Ad) Almost 80,000 tech jobs vanished in the first three months of 2026. Meta cut 14,000 roles, Microsoft offered separation packages to 8,500 workers, and Oracle is reportedly eliminating up to 30,000 positions. Goldman Sachs estimates 12,400 Americans are being financially displaced every single day. Analyst Porter Stansberry says the real driver runs deeper than AI - and two Nobel Prize winners have issued the same warning. He calls it the Final Displacement, and he's releasing a full investigation with specific companies to buy and sell before the next wave hits.

The math on the SpaceX IPO is broken (Ad) SpaceX is expected to go public at a $1.75 trillion valuation. For investors to see a 10x return, the company would have to reach $17.5 trillion - more than Apple, Microsoft, and Nvidia combined. But there may be a smarter play: a tiny supplier, just 1/60th the size of SpaceX, has already shipped 5 billion critical components to the company over the last decade. Once SpaceX goes public this June, Wall Street analysts will likely tear through the supply chain and put this under-the-radar vendor on the map. Get the full details on this overlooked supplier before the June IPO. Discover the under-the-radar SpaceX supplier before Wall Street does
