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

First Look: Elon’s “Starphone” (Ad)

Rumors are swirling that Elon Musk is developing a new mobile device that could rival the iPhone. It's said to be thinner, longer-lasting on battery, and cheaper to produce, with the ability to work worldwide without relying on cell towers. Former Bloomberg reporter and SAC Capital trader Josh Baylin says the evidence is mounting. He notes the FCC recently gave Musk a green light connected to his mobile plans, adding fuel to speculation. Baylin previously called the smartphone boom in 2004 and predicted Apple would sell a billion phones when others expected a fraction of that.tc pixel
