Stranded On The Flood Plains of History (Ad)

The petrodollar arrangement that Kissinger brokered in 1974 officially expired in June 2024. China has slashed U.S. Treasury holdings by 45% from peak, and central banks are swapping dollars for gold at the fastest pace since the Cold War. Porter Stansberry believes Trump is channeling more than $3 trillion toward securing the minerals, chips, and infrastructure that make AI possible - and companies at those chokepoints like Vertiv (up 500%), GE Vernova (up 700%), and Arista Networks (up 750%) are already moving. Porter's new briefing names one asset to buy today plus five stocks positioned at the narrowest chokepoints of what he calls the Silicon Dollar.tc pixel
