Aalo Atomics has raised US$100 million in a series B round to build its first nuclear reactor, targeted to begin operations in summer 2026 at Idaho National Laboratory.

The US-based company is developing small modular reactors inspired by the Marvel design created at the Department of Energy lab.

Aalo’s CTO, Yasir Arafat, previously led the Marvel project, and the company has received support from the Idaho National Lab under a US government initiative.

The round was led by Valor Equity Partners, with participation from 50Y, Alumni Ventures, Crescent Enterprises, and others.

Aalo plans to develop its Aalo Pod plants, each using five reactors to generate up to 50 megawatts of electricity. The company also intends to build a prototype with an experimental data center next to the reactor.

However, the nuclear industry has faced frequent delays, and it remains to be seen if Aalo can meet its projected timeline.

🧠 Food for thought

1️⃣ Nuclear startups face persistent timeline challenges despite optimistic projections

Aalo’s aggressive summer 2026 target stands in stark contrast to the nuclear industry’s historical pattern of extended development timelines.

When Terrestrial Energy raised funding in 2016, CEO Simon Irish aimed to commission the company’s first commercial plant in the 2020s2. Similarly, X-energy received a $40 million DOE grant in 2016 but set their demonstration reactor goal for 20353.

These extended timelines reflect the complex regulatory and technical challenges that have historically plagued nuclear development, where projects routinely face delays beyond initial projections.

Aalo’s July 4, 2026 criticality target represents a compressed timeline for the industry. The company is leveraging its location on DOE property at Idaho National Laboratory and using established UO₂ fuel to avoid supply chain bottlenecks that typically extend development schedules4.

2️⃣ Big tech’s nuclear investments are reshaping energy market dynamics

Tech giants are driving significant demand for nuclear power to meet their data center energy needs, altering the nuclear investment landscape.

Data centers consumed approximately 1.5% of global electricity in 2024, with projections showing this could reach 945 terawatt hours by 20305. This growth is prompting strategic shifts, with Amazon partnering on small modular reactors and Microsoft signing agreements to secure over 800 MW of clean power67.
