How the AI boom got US utilities to refocus on nuclear energy, in one chart

Out with ESG, in with AI.

Keeping the semiconductor brain cells that facilitate artificial-intelligence applications firing on all cylinders requires a lot of energy.

The constraint on the AI boom right now, according to Microsoft, is that there simply aren’t enough data centers. Once that choke point is cleared, that’ll bring into even sharper relief the need for power to keep those energy guzzlers going.

This demand is crying out for supply, and Big Tech is increasingly turning toward the Nuclear Option.

Utilities companies have gotten the message loud and clear. In a sign of how the once dominant “decarbonization” theme — closely linked to the rise of ESG-centric investment mandates — has ceded ground to this new AI theme, US utility companies are talking far more about nuclear energy now than they are solar or wind energy.

The higher consistency of nuclear energy makes it a more appealing baseload source of power, especially in the case of smaller modular reactors where output can be tailored to better meet the needs of the tech giants.

Entergy went from mentioning nuclear zero times during its quarterly earnings update in August to talking up its “new nuclear” options and potential upgrades to existing assets a whopping 22 times, the most in the sector, in its October call. And executives at NextEra Energy mentioned “nuclear” as many times in their most recent quarterly call as the previous three years combined.

This ramp-up in mentions of nuclear by utilities companies comes despite Constellation Energy’s C-Suite dropping way fewer references to it compared to the first half of 2024, even as they announced plans to restart the Three Mile Island plant in Pennsylvania.

In some respects, this catch-up in commentary is long overdue. Nuclear has long been a much more important source of US net power generation than solar and wind!

Optics stocks rise after Lumentum CEO says demand is strong with "no end in sight"

Lumentum rose more than 5% in premarket trading on Friday, and lifted its competitors with it, after the company's CEO told Bloomberg that demand for its optical components is through the roof.

Chief Executive Officer Michael Hurlston told the outlet Friday that the company is "falling further and further behind the demand" and would be sold out through all of 2028 within two quarters.

“The capex numbers from the US hyperscalers are enormous and there seems to be no end in sight,” he said.

The comments also bolstered the Lumentum's peers, with Applied Optoelectronicsand Coherent also in the green in early trades this morning.

These companies make optical components that use light — rather than traditional copper interconnects — to move data within and between servers in data centers, a technology increasingly seen as critical for scaling artificial intelligence capacity.

Earlier this month, Nvidiasaid that it would invest $2 billion apiece in Coherent and Lumentum to develop their advanced optics technologies.

TSMC rises on 35% sales jump in Q1 as AI demand holds strong

TSMC is up more than 2% in premarket trading after the world’s largest chipmaker reported a 35% jump in first-quarter revenue, beating Wall Street expectations on continued strong demand for AI chips.

Revenue from January through March rose 35% year over year to 1.13 trillion new Taiwan dollars ($35.6 billion), marginally topping consensus estimates of 1.12 trillion new Taiwan dollars. March revenue alone surged 45% from a year earlier.

The strong topline figures suggest that demand for TSMC’s chips — used in everything from smartphones to massive data centers — remain robust, with strong order momentum from major customers including Apple, Nvidia, AMD, and Broadcom, even as concerns rise that Middle East war could dent global AI infrastructure spending.

Price hikes for its advanced chips may have also contributed to the sales beat.

The company is set to report first-quarter earnings on April 16, alongside updated guidance for the current quarter and full year.

Shares have gained roughly 30% year to date.
