The Short Answer
Oklo stock (OKLO) is considered halal under standard Sharia screening. Generating and selling clean electricity from advanced nuclear fission is a permissible activity with no haram revenue line, and Oklo funds itself primarily through equity, so it passes the debt screen.

Business-activity disclosure
Oklo is developing advanced fission powerhouses and nuclear-fuel recycling. Clean-energy generation is generally permissible, but Oklo remains pre-revenue and the filing does not provide a universal prohibited-activity numerator across future projects, counterparties or end uses.
Limitation: No operating revenue was reported for the quarter, so an interest-income-to-revenue ratio cannot be calculated without inventing a denominator; future commercial activity remains qualitative.
Purification
Oklo reports investment income while pre-revenue; no revenue-based purification percentage can be calculated and ZakatInvest does not prescribe a scholar-approved percentage.
Inputs, assumptions and primary sources
- Amounts are USD millions from Oklo's March 31, 2026 Form 10-Q.
- The filing does not report interest-bearing debt; convertible or project debt should be added when issued.
- Cash and cash equivalents are $1,594.103 million and available-for-sale debt securities are $942.795 million, consisting primarily of Treasury securities and commercial paper.
- Interest receivable of $9.710 million plus other receivables of $1.669 million are included; the filing reports no operating revenue for the quarter because Oklo remains pre-revenue.
- The filing reports $21.339 million of investment income and $0.138 million of investment interest/accretion, but no operating-revenue denominator exists, so the income ratio is unavailable rather than fabricated.
- Advanced nuclear power and fuel recycling are generally permissible, while project counterparties, licensing and future end uses remain qualitative.
This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.
The main caveats are that Oklo is an early-stage, largely pre-revenue company whose ratios will evolve, and that interest earned on its substantial cash balance should be checked and purified.
Sharia Screening Methodology
Islamic scholars use several criteria to screen stocks:
- Business activity screen: Is the company's primary business halal?
- Debt ratio: Total debt / market cap must be under 33%
- Interest income: Interest income / total revenue must be under 5%
- Haram revenue: Revenue from haram sources must be under 5%
- Receivables ratio: Total receivables / total assets must be under 49–70% (varies by board)
Oklo's Business Activity
Oklo Inc. is developing advanced fission power plants — its "Aurora" powerhouses — to sell clean electricity under long-term power-purchase agreements, and is pursuing nuclear-fuel recycling. Its activity is:
- Clean power generation: Selling electricity from advanced nuclear reactors
- Power-purchase agreements: Long-term contracts to supply customers
- Fuel recycling: Recovering and reusing nuclear fuel
Generating and selling electricity is a permissible activity, and clean-energy generation aligns with Islamic principles of stewardship.
Why OKLO Is Halal
1. Permissible Core Business
Nuclear clean-energy generation is a halal activity. There is no gambling, alcohol, conventional banking, or other prohibited line at the heart of the business.
2. Equity-Funded Balance Sheet
Oklo funds itself primarily through equity rather than interest-bearing debt and holds a substantial cash position, so the debt-to-market-cap ratio passes the 33% Sharia threshold comfortably.
3. Early-Stage Caveats
Oklo is largely pre-revenue and speculative; its ratios should be re-screened as it commercializes, and interest income on cash should be checked against the 5% threshold and purified.
Current quantitative Sharia screen
Oklo's Form 10-Q for the period ended March 31, 2026 (figures in USD millions) shows a pre-revenue company with no operating-revenue denominator yet:
- Debt / total assets: 0.00% (no interest-bearing debt reported / USD 2,703.509m) — passes the asset-based debt test.
- Cash + interest-bearing securities / total assets: 93.84% (USD 2,536.898m / USD 2,703.509m), including Treasury and commercial-paper holdings.
- Receivables + cash / total assets: 59.39% (USD 1,605.482m / USD 2,703.509m).
- Operating revenue: USD 0; interest income cannot be divided by operating revenue until commercialization, so no percentage is asserted.
Methodology interpretation
The nuclear-energy activity is qualitatively permissible and the reported debt ratio passes. However, OKLO is pre-revenue and holds substantial interest-bearing securities, so the income screen and purification amount are not yet determinable from an operating-revenue denominator. This analysis is not an official certification by a screening provider.
Bottom Line
Oklo (OKLO) is qualitatively halal but quantitatively incomplete for Muslim investors. The advanced nuclear clean-energy business is permissible and the reported debt ratio passes, but the company has no operating revenue yet and holds substantial interest-bearing securities. Treat it as a speculative, early-stage holding and re-screen it as commercialization produces revenue and a measurable purification denominator.
For Muslim investors seeking clean-energy and infrastructure exposure, compare OKLO with peers like NuScale Power (SMR) and Tesla (TSLA).
