Almost everyone owns the same five AI stocks. Almost nobody owns the stuff those stocks depend on.

There is an old line about the gold rush: the people who reliably got rich were not the miners, they were the ones selling picks and shovels. The AI boom has its own picks and shovels, and this week a few quietly Canadian ones showed up in the headlines. For a cross-border investor whose portfolio is anchored to a handful of crowded US technology names, that is worth paying attention to.

The picks and shovels of the AI boom

The AI story is usually told through chips and hyperscalers. Underneath it sits a far less glamorous layer: the power, the materials, and the infrastructure the whole thing runs on. That layer is where Canada holds a surprising number of cards, and it is where a home-market investor can find exposure to the same secular theme without simply buying more of what everyone already owns.

Helium: no substitute

Start with helium. This week an economist flagged a big opportunity to boost the global footprint of Canadian helium as the AI buildout accelerates, because there is no substitute for the gas in semiconductor manufacturing. The timing is not an accident: a major Middle East facility that supplies close to a third of the world’s helium has been offline, and repairs are expected to take years. Saskatchewan, already Canada’s leading helium producer, accounts for roughly 3% of global supply and is targeting 10% by 2030. When demand is structural and a key competitor is offline, that is the kind of setup that rewards the picks-and-shovels supplier.

Antimony and the defence angle

Then there is antimony, a mineral most people have never heard of that has become a national-security issue. A Canadian miner spent this week making its case to supply antimony into the US defence supply chain. The backdrop is that China restricted exports of the mineral in late 2024, exposing a real North American supply gap, and roughly 40% of US antimony use goes into ammunition. This is the cross-border story in miniature: a Canadian resource, an American strategic need, and a supply chain being redrawn in real time.

Washington just drew a line

The policy backdrop hardened this week too. On August 6, the White House rolled out new trade actions on solar and chip materials, setting a 15% tariff and minimum import prices on polysilicon and related products under a national-security provision, explicitly to compete with China on AI and energy. When Washington starts protecting the materials layer, it is telling you where it thinks the real chokepoints are, and those chokepoints are exactly the picks and shovels.

The names that ran

None of this slowed the front end of the AI trade. Arista Networks, a key supplier of AI networking gear, posted its first three-billion-dollar quarter and raised its 2026 revenue outlook toward roughly 40% growth, its third increase this year. Strong results also came from AMD, Cloudflare, and Microchip, and Canada’s own MDA Space beat expectations. The demand is real. The question, as always, is price, and how much of it you already own.

Why this matters for a cross-border investor

Most of our clients experience AI as a handful of US mega-cap names, which quietly concentrates their risk in one crowded corner of one market. The picks-and-shovels view reframes it. Canada’s critical minerals, its power, and its specialty resources offer a way to participate in the same theme from a different, home-market angle. To be clear, this is not a tip to go buy a mining stock. It is a case for thinking one layer beneath the obvious trade, and for making sure your AI exposure is diversified rather than five names deep. That is the kind of question a cross-border specialist is built to answer.

Frequently asked questions

What does “picks and shovels” mean in the AI trade?

It refers to investing in the infrastructure and raw materials a boom depends on, rather than the headline products. In AI, that means the power, chips, networking gear, and critical minerals the buildout runs on, instead of only the best-known chip stocks.

Why is Canadian helium suddenly valuable?

Helium has no substitute in semiconductor manufacturing, and a major Middle East facility supplying close to a third of global helium has been offline. That has put a spotlight on Canadian producers, especially in Saskatchewan, as AI-driven chip demand grows.

What is antimony and why does the US military want it?

Antimony is a critical mineral used heavily in ammunition and defence applications. After China restricted exports in late 2024, North America faced a supply gap, and Canadian miners are now positioning to help fill it.

What did Washington do on solar and chips this week?

On August 6, 2026, the White House set a 15% tariff and minimum import prices on polysilicon and related solar and semiconductor materials under a national-security provision, aiming to compete with China and build domestic supply.

Does this mean I should buy Canadian mining stocks?

No. This is a way of thinking about a theme, not a recommendation to buy any specific stock. The point is to make sure your AI exposure is diversified and intentional rather than concentrated in a few popular names.
