Bloom Energy vs. Oklo: Which Industrials Stock Is a Better Buy in 2026?

As energy demand from artificial intelligence centers surges, investors are searching for the next big power play. Choosing between Bloom Energy (NYSE:BE) and Oklo (NYSE:OKLO) requires weighing established technology against future potential.

Bloom Energy provides fuel cells for onsite electricity, while Oklo develops advanced nuclear reactors. Both companies target the growing needs of data centers and utilities, but they operate at very different stages of commercial maturity.

The case for Bloom Energy

Bloom Energy primarily serves the utility stocks sector by providing solid oxide fuel cells for onsite electricity generation. These systems convert fuels like natural gas or hydrogen into power without combustion, serving data centers and semiconductor manufacturers. Customer concentration like this adds a layer of risk to the business, particularly with partners like American Electric Power (NASDAQ:AEP) and Brookfield (NYSE:BN). In its latest annual report, the company also identified Meta Platforms (NASDAQ:META) as a major customer for a large power campus project.

In FY 2025, revenue reached nearly $2.0 billion, which was a 37.3% increase compared to the previous year. This growth followed an increase from approximately $1.5 billion in 2024. Despite this top-line expansion, the company reported a net loss of roughly $88.4 million for the fiscal year. This loss was wider than the nearly $29.2 million net loss recorded in the prior year.

As of its December 2025 balance sheet, the debt-to-equity ratio was approximately 3.9x. This metric shows how much debt a company uses relative to its shareholder equity. The current ratio, which measures the ability to cover short-term liabilities with current assets, was close to 6.0x. Free cash flow, which is cash from operations minus capital expenditures, was nearly $57.2 million for the year.

The case for Oklo

Oklo is a pioneer in the advanced nuclear space, focusing on fast fission reactors designed for rapid deployment. The company plans to sell power and heat directly to customers while also recycling spent nuclear fuel. It has secured a master power agreement with Switch and maintains non-binding letters of intent with Equinix (NASDAQ:EQIX) and Diamondback Energy (NASDAQ:FANG). It is also exploring opportunities with the Tennessee Valley Authority (NYSE:TVC) for power sales and fuel recycling services.

In FY 2025, revenue was $0.0 because the company has not yet commercialized its reactor technology. This lack of revenue resulted in a net loss of approximately $105.7 million for the year. The losses have widened from roughly $73.6 million in 2024 as the company continues to scale its research and development operations.

As of its December 2025 balance sheet, the debt-to-equity ratio was 0.0x. This indicates that the company carries very little debt relative to its equity. Its current ratio was approximately 49.1x, reflecting a large stockpile of liquid assets to fund its development stage. Free cash flow was negative $115.4 million for the year as the company invests in its first-of-a-kind reactor designs.

Risk profile comparison

Bloom Energy faces competition from traditional grid power and alternative energy sources. The company is exposed to supply chain disruptions and volatile costs for rare earth metals. It also faces legal risks, including a securities class action lawsuit related to its supply chain practices. Additionally, regulatory uncertainty regarding government incentive programs and tax credits could impact its future growth.

Oklo is an early stage business with no operational reactors currently constructed. It relies on a specific fuel type that is not yet available at scale. The company must navigate complex licensing with the Nuclear Regulatory Commission, which involves significant uncertainty. It also faces intense competition from established energy providers and potential delays in constructing its first reactor.

Valuation comparison

Bloom Energy carries measurable valuation multiples, while Oklo remains a speculative pre-revenue play with no traditional earnings or sales metrics yet available.

Which stock would I buy in 2026?

I'd go with Bloom Energy, and after its most recent quarter, the results speak for themselves. The company crossed $1 billion in quarterly revenue for the first time, with product revenue more than tripling year over year as hyperscalers and AI data centers adopted its fuel cell systems at an accelerating pace. Management raised its full-year outlook to reflect roughly double the revenue it generated in all of 2025. The company turned operating losses into operating profits, and a partnership with Brookfield providing up to $25 billion in project financing gives it the runway to keep scaling.

Oklo, to its credit, is building toward something that could matter enormously in the long run. Advanced nuclear power is gaining traction as a solution for AI data center energy needs, and Oklo's integrated model of building and operating its own reactors is differentiated. But Oklo is still years from generating commercial revenue and it's burning through cash in the meantime.

Bloom Energy is already delivering power to the AI infrastructure buildout today. For investors with patience and a long horizon, owning the company already generating results beats waiting on one that is still working to build its first commercial reactor.
