Is Quantum-Si, Inc. QSI stock Halal to invest in?

No, as of September 2026, Quantum-Si, Inc. stock (QSI) is not currently classified as a Shariah compliant stock. This verdict follows the screening methodology of AAOIFI (the Accounting and Auditing Organization for Islamic Financial Institutions), whose Shariah Standard No. 21 is the leading global benchmark for screening Halal stocks. To qualify as Halal under this standard, a company must keep non-permissible income below 5% of total revenue, keep both interest-bearing investments and interest-bearing debt below 30% of market capitalisation, and have no impermissible preference share structure. Quantum-Si, Inc. currently does not meet the threshold for the non-permissible income and interest-bearing investments screens. Because screenings are refreshed monthly as new financial reports are published, a non-compliant stock can regain compliant status if its financial structure changes. You can track the latest status of Quantum-Si, Inc. and discover Shariah compliant alternatives among the Halal stocks in the Tabadulat app.

How often is Quantum-Si, Inc. QSI reviewed for Shariah compliance?

Tabadulat reviews Quantum-Si, Inc. QSI for Shariah compliance every month. Each review applies the AAOIFI Shariah Standard No. 21 methodology, screening the company's business activities, non-permissible income, interest-bearing investments, interest-bearing debt, and preference shares, against the company's latest available financial data. The process operates under the direct supervision of Tabadulat's dedicated Shariah Supervisory Board of Islamic finance scholars. Because compliance depends on financial ratios that move with market capitalisation and reported results, a stock's status can change from one review to the next. Monthly screening ensures the status shown for Quantum-Si, Inc. reflects current financial data rather than an outdated assessment, and Tabadulat app users are notified if a holding in their portfolio becomes non-compliant.

Does Quantum-Si, Inc. QSI pass the AAOIFI Non Permissible Income criteria?

No, as of September 2026, Quantum-Si, Inc. stock (QSI) does not pass the AAOIFI non-permissible income screen. Under AAOIFI Shariah Standard No. 21, income from impermissible sources (such as interest or Riba, conventional financial services, alcohol, gambling, or tobacco) must remain below 5% of a company's total revenue. Quantum-Si, Inc.'s income from non-permissible sources currently exceeds this 5% ceiling, which makes the stock non-compliant on this criterion regardless of how it performs on the other screens. The screen is reassessed monthly, so the status can change when the company releases new financial statements.

Does Quantum-Si, Inc. QSI pass the AAOIFI Interest Bearing Investments criteria?

No, as of September 2026, Quantum-Si, Inc. stock (QSI) does not pass the AAOIFI interest-bearing investments screen. Under AAOIFI Shariah Standard No. 21, the cash a company places in interest-earning instruments (such as conventional deposits, bonds, treasury bills and money-market funds) must remain below 30% of its market capitalisation. Quantum-Si, Inc.'s interest-bearing investments currently exceed this 30% limit, meaning too large a share of the company's value derives from Riba-based instruments for the stock to qualify as Halal on this criterion. The ratio moves with both the balance sheet and the share price, and is reassessed monthly.

Does Quantum-Si, Inc. QSI pass the AAOIFI Interest Bearing Debt criteria?

Yes, as of September 2026, Quantum-Si, Inc. stock (QSI) passes the AAOIFI interest-bearing debt screen. AAOIFI tolerates some conventional borrowing but draws the line at 30% of market capitalisation. On the latest data, Quantum-Si, Inc.'s interest-bearing debt stays below the line. Because market capitalisation changes daily, a company's debt ratio can drift toward or away from the limit even without new borrowing, which is why this screen is reassessed every month.

What is the dividend purification factor for Quantum-Si, Inc. QSI stock?

Quantum-Si, Inc. (QSI) is currently classified as not Shariah compliant, so no dividend purification factor applies, because purification factors are calculated only for stocks that pass the AAOIFI screens. Purification (Tazkiyah) is the practice of donating to charity the small portion of dividend income that stems from incidental non-permissible sources, such as interest earned on a compliant company's cash deposits. For non-compliant stocks the issue is not purification but eligibility: under AAOIFI Shariah Standard No. 21 the stock does not currently qualify as a Halal investment. If Quantum-Si, Inc. returns to compliance in a future monthly screening, its purification factor will be published alongside its updated status in the Tabadulat app.

Does Quantum-Si, Inc. QSI pass the AAOIFI Preference Share screen?

Yes, as of September 2026, Quantum-Si, Inc. stock (QSI) passes the AAOIFI preference share screen. AAOIFI Shariah Standard No. 21 prohibits investing in preference shares because they grant holders guaranteed or priority rights to dividends and capital ahead of ordinary shareholders, a structure that conflicts with the Shariah principle that investors should share profit and loss in proportion to their ownership. Quantum-Si, Inc. has no impermissible preference share structure affecting its ordinary shares, so the stock is compliant on this criterion. Like all AAOIFI screens, this is verified in each monthly review.

Quantum-Si is a biotechnology innovation company focused on revolutionizing the proteomics field, which is the large-scale study of proteins. Their primary aim is to develop and commercialize a groundbreaking semiconductor chip-based platform to analyze and sequence proteins. This platform is designed to deliver faster and more comprehensive proteome insights at a lower cost than traditional methods, broadening the accessibility and applicability of proteomic analysis. Before any of that matters to a Muslim investor, one question comes first: is Quantum-Si stock Halal?

Is Quantum-Si Shariah compliant?

Healthcare rarely troubles the activity screen; treating illness is permissible work. For Quantum-Si, the AAOIFI Shariah Standard No. 21 verdict turns on the balance sheet instead: research is capital hungry, and interest bearing debt and investments must each stay below 30% of market capitalisation.

Does Quantum-Si pass the business activity test?

The activity screen is only part of the picture this month: Quantum-Si currently fails the non-permissible income and interest-bearing investments screens, so the overall verdict is not compliant regardless of the business itself. Treating illness is permissible work; the scrutiny belongs to the financing behind it.

Is Quantum-Si's income Halal?

No. Quantum-Si'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 Quantum-Si meet AAOIFI's debt and investment ratio requirements?

Not in full. Interest bearing investments currently exceed the 30% cap, while the other ratio stays within it. One breach is enough to fail the screening; the ratios are reassessed monthly under our Shariah Supervisory Board.
