Bloom Energy, A.H.T. Syngas, Veolia: Waste is Giving Rise to a Multi-Billion-Dollar Market
Waste and industrial residues are evolving from a cost factor into a valuable raw material. Rising energy prices, decarbonization and the enormous power demands of new data centres are driving up the economic value of technologies that convert previously unused materials into energy. At the same time, pressure is mounting on industry and local authorities not only to dispose of waste but also to recycle and repurpose it. This is giving rise to a multi-billion-dollar market at the intersection of the circular economy and energy supply.

Cerebras, Volatus Aerospace, Standard Lithium: 3 Markets Poised for a Breakthrough
The next wave of investment is well underway. Billions are flowing into new AI data centres, Western nations are securing critical raw materials, and companies are increasingly automating tasks that previously had to be carried out by people, aeroplanes or helicopters. For investors, this creates opportunities that extend far beyond the well-known technology giants. Of particular interest are companies that provide the infrastructure for this development.

Ballard Power, First Hydrogen, ElringKlinger: Is Hydrogen Poised for a Fresh Start?
After years of billion-dollar investments and grand promises, the hydrogen industry must finally deliver. What matters now is no longer new letters of intent, but applications that will work in everyday life and that can be scaled economically. Fuel cells are now making their way into heavy-duty transportation, providers are bundling technology and hydrogen supply, and new areas of application are emerging beyond traditional vehicles. For investors, this could mark the beginning of a new phase. It is no longer merely the vision that matters, but rather who is actually turning hydrogen into a business.

AeroVironment, HPQ Silicon, BAE Systems: It Is All About the Battery
Drones are fundamentally changing modern warfare. What used to cost millions can now be reconnoitered or countered using comparatively inexpensive unmanned systems. Western nations are ramping up their procurement efforts accordingly. But as demand grows, so do the technical challenges. Range, payload, and endurance depend crucially on the power supply. More powerful batteries are thus becoming a key technology in the drone boom. Not only could the major defense contractors benefit from this, but also suppliers that have received little attention until now.

GE Vernova, RE Royalties, Canadian Solar – Billions Are Flowing Into Energy Infrastructure
The energy transition is no longer primarily a technological challenge, but rather a financing and infrastructure challenge. Solar farms must be built, battery storage systems financed, and power grids upgraded to support an increasingly decentralized energy supply. The project pipelines of major developers alone demonstrate the scale to which investment needs have now grown. At the same time, new business models are emerging for companies that not only build facilities but also provide capital or profit from the long-term returns of the projects. This marks the beginning of a second phase of the energy transition for investors. The focus now is on turning this massive expansion into a profitable business.

RTX, Almonty Industries, Rheinmetall – The Battle for Tungsten Escalates
Tanks, missiles, radar systems, and AI chips require high-performance materials. One of the most strategically important is tungsten. China accounts for more than 80% of global production and has already tightened its export controls. At the same time, Europe and the US are ramping up their defense production. This is driving not only demand but also political pressure to establish independent supply chains. As a result, Western tungsten projects are gaining strategic importance.

First Majestic Silver, Lahontan Gold, Pan American Silver: The Next Phase Has Begun
Gold and silver are among the big winners in the commodities markets in 2026. While gold benefits from geopolitical tensions, high government debt, and the search for safe-haven assets, silver gets an additional boost from industrial demand. Solar energy, electrification, power grids, and high-tech industries are facing a structurally tight supply. This creates an interesting scenario for mining stocks. Rising precious metal prices boost the margins of established producers and can simultaneously significantly improve the profitability of deposits that have not yet been developed. Three companies could benefit particularly from this.

Siemens Energy, Zefiro Methane, Centrus Energy: This Is Just the Beginning
Created and Published on Behalf of Zefiro Methane Corp.
The AI boom is increasingly turning into an energy boom. Data centers require enormous amounts of electricity, new generation capacity, and more robust grids. At the same time, nuclear energy is making a comeback, and even natural gas is regaining strategic importance as a readily available energy source. Billions are therefore being invested in infrastructure that has been neglected for decades. For investors, this creates several growth markets at once—from power grids and the retrofitting of existing energy plants to the establishment of an independent nuclear fuel supply.

BHP Group, Power Metallic Mines and KGHM Polska Miedź: A Revaluation Within Reach
Copper is becoming a strategic bottleneck. Power grids, data centers, electric mobility, and defense are driving demand, while new mines take years to reach production. Major producers are therefore searching for additional deposits and new extraction methods. Projects that contain several scarce metals in addition to copper are becoming particularly attractive. Three companies demonstrate the various ways investors can capitalize on this trend.

Alkane Resources, Desert Gold Ventures, Westgold Resources: Is the Gold Correction Over?
Gold is making a strong comeback. The price of the precious metal jumped above USD 4,600 per ounce at the end of the week and posted a 5.6% gain, marking its third consecutive weekly increase. For producers, this means rising margins and cash flows, while deposits that were previously uneconomical could become significantly more attractive for explorers. At the same time, new corporate announcements demonstrate just how valuable additional reserves have become. Investors should therefore not focus solely on the major mining operators.
