Is Oklo (OKLO) stock Halal?

Oklo is a clean energy technology company dedicated to transforming the global energy landscape by developing compact, advanced fission reactors. Its primary mission is to provide reliable, carbon-free power generation solutions with small, modular nuclear reactors. These reactors are designed to be safe, efficient, and economically viable, aiming to meet energy demands sustainably without the greenhouse gas emissions associated with traditional fossil fuels. Before any of that matters to a Muslim investor, one question comes first: is Oklo stock Halal?

Is Oklo Shariah compliant?

No. In the October 2026 screening Oklo (OKLO) does not pass AAOIFI screening: it fails the non-permissible income screen. For a utility like Oklo, AAOIFI Shariah Standard No. 21 has little quarrel with the service itself; the scrutiny falls on how the infrastructure is financed. Regulated networks are usually built with long term borrowing, which the standard tolerates only below 30% of market capitalisation, a ratio that moves with the share price as well as the debt.

Does Oklo pass the business activity test?

The activity screen is only part of the picture this month: Oklo currently fails the non-permissible income screen, so the overall verdict is not compliant regardless of the business itself. Delivering power or water raises no Shariah objection in itself; the scrutiny belongs to the debt behind the network.

Is Oklo's income Halal?

No. Oklo's income from impermissible sources currently exceeds AAOIFI's 5% revenue ceiling, which makes the stock non-compliant on this screen regardless of the others. The screen is reassessed monthly, so the status can change when new financial statements arrive.

Does Oklo meet AAOIFI's debt and investment ratio requirements?

Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation, measured against a market capitalisation of $6.89B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has OKLO re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for Oklo?

Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.
