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.

"You'll own nothing and be happy" (it's not a theory anymore) (Ad) Since 1913, the evidence is clear… Once they force everyone onto CBDCs, there will be no escape. Every transaction will be tracked. Every account will be programmable. Every dollar will be subject to government control. But here's what they didn't count on... Decentralized finance has created a backdoor out of their system. And right now, that door is still open. Watch how to protect yourself from what's coming.
