Is Rocket Lab Stock (RKLB) Halal? A Complete Analysis

The Short Answer

Rocket Lab stock (RKLB) is doubtful (mashbuh) for Muslim investors. The core commercial space launch business — putting small satellites into orbit — is permissible. However, Rocket Lab derives a significant and growing portion of its revenue from US defense and intelligence agencies for military satellite launches, spacecraft components for defense systems, and classified government missions. This defense revenue mix makes RKLB a borderline case.

Muslim investors who avoid all defense-adjacent investments should avoid RKLB. Those who distinguish between defensive and offensive military technology may take a different view.

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)

Rocket Lab's Business Activity

Rocket Lab operates in two segments:

• Launch Services (~40% of revenue): Small satellite launches using the Electron rocket. Customers include commercial companies, universities, and government agencies including NASA, the US Space Force, and defense intelligence agencies.
• Space Systems (~60% of revenue): Manufacturing spacecraft components (solar panels, reaction wheels, radios, separation systems) and building complete satellites for clients. A growing portion of space systems revenue comes from defense and intelligence customers.

The commercial portion of Rocket Lab's business — launching commercial satellites for Earth observation, communications, and research — is entirely permissible. The concern lies with the defense and classified government work, which is growing rapidly as Rocket Lab wins contracts from the US military.

The Defense Revenue Concern

Islamic scholars have nuanced views on defense companies:

• Weapons manufacturing: Companies that make weapons designed primarily to kill (missiles, bombs, firearms) are generally considered haram by most scholars
• Defense infrastructure: Companies providing logistics, electronics, or support services to military organizations occupy a gray zone
• Dual-use technology: Technologies like satellite launch that serve both civilian and military purposes are debated

Rocket Lab's situation is complicated by the fact that defense revenue is increasing significantly and includes work on classified intelligence missions. While Rocket Lab does not make weapons directly, launching surveillance and communications satellites for military and intelligence agencies can enable military operations.

Most mainstream Sharia screening agencies apply a revenue threshold — if defense/weapons revenue exceeds 5% of total revenue, the stock fails. Rocket Lab likely exceeds this threshold given its growing government defense contracts.

Financial Ratios (2025)

Based on Rocket Lab's most recent financial statements:

• Total Debt / Market Cap: ~15% ✅ (threshold: under 33%)
• Interest Income / Revenue: ~3% ✅ (threshold: under 5%)
• Defense Revenue: Significant and growing — likely above 5% threshold ❌

Rocket Lab passes the quantitative financial screens but faces a meaningful business activity concern due to growing defense revenue.

Verdict from Major Screening Agencies

Rocket Lab stock is screened as doubtful or non-compliant by most agencies:

• Zoya App — Questionable/Non-Compliant ❌
• MSCI Islamic criteria — Does not meet criteria ❌
• Most major Sharia advisory boards — Not Approved (defense threshold exceeded) ❌

Bottom Line

Rocket Lab (RKLB) is doubtful and generally not halal for Muslim investors under mainstream Sharia screening. While commercial space launch is permissible, the company's growing defense and intelligence revenue — including classified military satellite launches — creates a meaningful Sharia concern that mainstream screening agencies flag as non-compliant.

Muslim investors interested in space technology should monitor whether the commercial vs. defense revenue mix evolves. Currently, the defense exposure makes RKLB unsuitable for Sharia-compliant portfolios.
