Amazon's Indiana Nuclear Plant and the AI Power Race

TL;DR: Amazon is funding development of a proposed 960-megawatt nuclear plant at a former coal site in Indiana, with American Electric Power and X-energy. It would use 12 small modular reactors and Amazon would be the first customer. The project is still a feasibility study, and no final investment decision has been made.

What did Amazon, AEP and X-energy announce?

On Oct. 19, 2026, American Electric Power announced a joint development agreement with X-energy to evaluate the feasibility of a 960-megawatt advanced nuclear project at a former coal plant site in Sullivan County, Indiana. The initial project would include 12 Xe-100 units of 80 MW each, configured in groups of four.

Amazon's role is the money and the demand. TechCrunch reported that Amazon is funding development and would be the first customer to buy the plant's power. AEP would operate the plant and X-energy would supply the reactors.

Item	What the sources say
Location	Former coal plant site, Sullivan County, Indiana
Size	960 MW, from 12 Xe-100 units of 80 MW each
Operator	American Electric Power
Reactor supplier	X-energy
Amazon's role	Funds development, first power customer
Status	Feasibility evaluation, pending a final investment decision

The table shows how early this is. Every row describes a plan, and the last row decides whether the others ever get built.

Why does an AI company want its own nuclear plant?

Because data centers never sleep. The chips are only useful if the power stays on, and Investing.com noted that nuclear plants can generate large amounts of electricity continuously under suitable operating conditions, which makes them attractive for data centers operating 24 hours a day.

This isn't Amazon's first nuclear bet. The Indiana project pays for new capacity that doesn't exist yet, and it carries the risk that comes with that.

For context on how another hyperscaler approached the same problem, see our earlier look at Google's nuclear deal and the grid it plugs into.

How does the Xe-100 reactor work?

The Xe-100 is a small modular reactor design from X-energy. Investing.com reported that, unlike conventional nuclear reactors, it uses helium gas rather than water as a coolant. Small modular reactors are built in compact units and added in groups, which is why the Indiana plan is expressed as twelve 80 MW blocks.

That modular approach is also where the uncertainty sits. TechCrunch noted that X-energy has yet to break ground at Seadrift, the site that will host four Xe-100 reactors for a chemical plant. The design is still waiting on its first build.

What does it mean for investors?

The clearest read is on X-energy's stock. X-energy debuted on the Nasdaq in April at $23 per share, and TechCrunch reported that the price rose 27% on the first day but has since dropped by nearly two-thirds. News of the Amazon deal lifted shares about 10% in premarket trading, though they were down by less than 2% at the time of that report. A customer commitment helped. The market is still pricing in delivery risk.

The relationship also runs deep. According to the same report, Amazon led a $700 million Series C-1 round in X-energy in October 2024, and the two companies have said they ultimately plan to build 5 gigawatts of new nuclear capacity in the U.S. The Indiana deal is their second commercial agreement and is three times larger than the first.

For accredited investors, the useful frame is that AI exposure now runs through power. Private and public bets on grid capacity, fuel and reactor makers all depend on projects like this one getting approved and built. Our coverage of Helion's fusion raise and Anthropic's Series H shows the same pattern from two other directions.

What could go wrong?

AEP itself frames the deal conditionally. The release says that if the project reaches a final investment decision and moves forward with construction and commercial operation, the facility would add electricity to the grid. Until then, it is an evaluation. The sources reviewed give no construction start date or operating date, so any timeline you see elsewhere is a guess.

Common mistakes

The most common error is reading a feasibility agreement as a built plant. A joint development agreement commits money to study and plan. It isn't a construction contract.

A second error is treating one customer's commitment as proof the technology works. The reactor design hasn't yet been built at commercial scale, so a large buyer reduces demand risk without removing technical risk.

The third is judging X-energy by one day's move. The shares have swung sharply in both directions since the April IPO, and a 10% premarket jump says little about delivery.

FAQ

Can nuclear power really fuel the rise of AI? It can supply the steady, round-the-clock power data centers need. The open question is timing. New reactor designs like the Xe-100 haven't been built commercially yet, so near-term AI power still depends on existing plants and the grid.

Is Amazon behind in the AI race? This deal doesn't answer that. It addresses electricity supply, not model or chip performance. It does show Amazon paying to secure long-term power, as other large technology companies have done.

What nuclear company is Amazon investing in? X-energy, which designs small modular reactors. Amazon led a $700 million Series C-1 round in October 2024, according to TechCrunch. X-energy has since listed on the Nasdaq.

Who would operate the Indiana plant? American Electric Power would operate it, according to TechCrunch's report of the announcement. X-energy would supply the reactors and Amazon would be the first customer for the power.
