Two big stories are moving markets today: a landmark nuclear power deal between Constellation and Alphabet, and a massive funding round for Chinese AI firm DeepSeek. Both are about the same underlying trend—the explosive growth of artificial intelligence and the energy it demands.
Constellation and Alphabet: powering the AI boom
Constellation Energy, the largest nuclear power operator in the US, has signed a mega deal with Alphabet, Google's parent company. The agreement will see Constellation supply nuclear power to Alphabet's data centers, which are voracious consumers of electricity. This is part of a broader pattern: tech giants are scrambling to secure reliable, carbon-free power to run their AI operations without derailing their climate commitments.
Nuclear power is uniquely suited to this task. It runs around the clock, unlike solar or wind, and produces no carbon emissions. That's why Constellation has already inked multi-year agreements with Microsoft, Meta, and Amazon. The Alphabet deal is the latest in a series of such partnerships, and it underscores how central energy has become to the tech sector's growth plans.
For investors, this is a reminder that the AI boom isn't just about chipmakers and software companies. The infrastructure that supports AI—including power generation—is a critical piece of the puzzle. Constellation's stock has been a beneficiary, and the company's nuclear fleet is now seen as a strategic asset in the age of AI.
Nuclear's moment: energy security and stable prices
Nuclear power is having a broader moment, too. Governments are eyeing it not just for its climate benefits but also for energy security. This year's Middle East conflict has rattled oil and gas markets, prompting countries to seek supplies less vulnerable to geopolitical shocks.
Uranium, the fuel for nuclear reactors, tends to have more stable prices than fossil fuels. Demand is predictable because reactors run 24/7, and operators typically re-up on uranium every 18 to 24 months. Even if prices swing, uranium is only a fraction of a plant's costs—the bulk comes from converting the metal into power. Plus, uranium is incredibly energy-dense, so countries can stockpile years' worth in a small space.
This stability is attractive to both governments and investors. For those looking to bet on energy security, nuclear offers a compelling narrative. As one analyst noted, Constellation's nuclear fleet is a core holding in a utilities strategy, and the Alphabet deal validates that view.
DeepSeek's $12 billion raise: China's AI ambitions
On the other side of the world, Chinese AI firm DeepSeek is reportedly set to raise over $12 billion in its latest funding round. The company originally sought $7.5 billion at a valuation of around $74 billion, but investors—reportedly including Tencent and battery maker CATL—lined up to pour in more. The round is still open, so the final figure could grow.
DeepSeek needs the cash: it's building a data center in Inner Mongolia that could cost tens of billions. The firm's latest model has earned rave reviews for its strong performance at a fraction of the cost of premium models from US rivals like OpenAI and Anthropic. That cost advantage has made DeepSeek a darling of the AI investing world.
For markets, this bodes well for DeepSeek's potential public listing next year. It probably won't be the only Chinese AI giant to go public—Moonshot AI is reportedly eyeing a Hong Kong listing, with a valuation around $50 billion and annualized sales of $1 billion.
What it means for investors
These stories highlight two key investment themes: the energy demands of AI and the global race for AI dominance. For everyday investors, the takeaway is that AI's impact extends beyond tech stocks. Utilities, particularly nuclear, are becoming essential players in the AI supply chain. Meanwhile, Chinese AI firms are attracting massive capital, but they come with regulatory risks—Chinese regulators have reportedly opened data-security investigations into both DeepSeek and Moonshot, which could dent valuations and delay listings.
There's also a cautionary note from history. Adjusted for inflation, America's AI sector is on track to borrow more this year than cable companies did during the internet build-out, and more than railroads did during the 19th-century boom. Those were gigantic borrowing binges, and neither ended without a hangover. Investors should keep that in mind as the AI investment wave continues.
For now, the momentum is undeniable. Nuclear power is enjoying a renaissance, and AI companies are flush with cash. But as always, it's wise to look beyond the headlines and consider the long-term fundamentals.
