"You need transformers to run transformers" — Musk (Ad)

Elon Musk recently laughed nervously and said, 'You need transformers to run transformers.' That wasn't a punchline - it's a constraint printed in the SPCX prospectus for a $2 trillion company. The world's largest supercomputer requires power equipment that takes 120 weeks to build. Musk built Colossus in 122 days. One small American company can close that gap faster than anyone else, and Wall Street still hasn't priced it in.tc pixel

Karp just filed Form 144 (Ad)

On May 12, 2026, Palantir CEO Alex Karp filed to sell 585,000 shares - roughly $95.93 million. Combined with filings from other Palantir executives that same week, total insider selling reached approximately $207 million. Michael Burry's final disclosed portfolio shows 97% in put options against Palantir and Nvidia. David Einhorn called this 'the most expensive market we have experienced' at the Sohn Conference - while his funds are up 6.5% year-to-date on defensive AI-bubble positioning. Porter Stansberry's 'The Final Displacement' identifies three positions to take before the public catches up.tc pixel
