The Trillion-Dollar AI Shockwave Nobody Is Ready For

The biggest investment opportunity of the AI era has very little to do with software or chips. The market has already priced both. The real story is power: who owns it, where it sits and how cheaply it can be delivered to AI workloads at scale. A small data center company that almost no one on Wall Street has heard of just answered all three of those questions in front of the entire industry. In May 2026, Bitzero Holdings Inc. (NASDAQ:AIBZ) signed a binding letter for a 15-year lease with OneQode for the entire 110 megawatts at its Namsskogan,…

Why the Next Billion Barrels of Oil Demand Could Come From Storage

The closure of the Strait of Hormuz and the stranding of more than 10 million barrels per day (bpd) of crude oil in the Persian Gulf was a wake-up call for import-dependent countries to expand their capacity to hold strategic and commercial reserves. Many countries, especially in the Asia Pacific, are looking to build new reserve capacity to boost their energy security and never again be caught off-guard by a massive supply disruption like the one triggered by the closure of the most important oil and LNG chokepoint. From India to Australia, energy…

Trump Admin Takes Aim at Oil, Gas Drilling Costs

The U.S. federal government will reduce costs for oil and gas drillers by slashing red tape for the industry, aiming to tempt drillers to expand on federal lands. In a news release this week, the Interior Department said it would revise the Bureau of Land Management’s rule for federal land leasing for oil and gas drilling as well as the BLM’s waste prevention rule, by essentially loosening both to reduce the cost burden on energy companies. Under the revised rules, the cleanup cost of an abandoned well will fall from $500,000 to as…

The AI Boom Is Set to Fast-Track China's Coming Nuclear Energy Dominance

The United States is still the largest producer of nuclear energy in the world – but probably not for long. Decades of political ambivalence have left the domestic nuclear sector in a state of neglect. Far more reactors are aging out than being constructed, and the country’s few attempts at building new nuclear fission reactors have been controversial, expensive, and slow to get off the ground. After Georgia’s Plant Vogtle finally came online years late and billions over budget in 2024, zero new reactors have since come under…

US Crude Oil Inventories Continue To Falter, SPR Struggling To Pick Up the Slack

The American Petroleum Institute (API) estimated that crude oil inventories in the United States fell by 765,000 barrels in the week ending June 19. In the week prior, US crude oil inventories fell by 8.33 million barrels. Although commercial crude oil inventories excluding the SPR have been falling rapidly for the last 2+ months, shedding 53 million barrels over the last ten weeks, US crude inventories are only down 2.1 million barrels so far this year, according to API data, kept in check by draws from the SPR. Slowing the inventory bleeding…
