Elon Musk’s Hushed FCC Filing. Sept 25th. (Ad)

Elon Musk quietly filed a document with the federal government tied to artificial intelligence, one of the largest markets in the world. James Altucher, who previously flagged Nvidia in 2008 and Bitcoin in 2013, says the filing could rival Tesla, SpaceX and xAI combined.

Trump goes "all-in" on Grand Canyon energy breakthrough (Ad)

A drilling crew near the Grand Canyon uncovered a clean energy well producing nearly eight times the output of Saudi Arabia's largest oil field, with potential to last two million years. While the One Big Beautiful Bill Act eliminated federal credits for solar, wind, and EVs, this energy source was reclassified alongside oil and nuclear power and given eight years of tax credits. Google signed a 15-year contract, and Bill Gates committed $100 million. One company controls the entire supply chain behind this discovery.tc pixel
