Is CSGP (CoStar Group, Inc.) Halal or Haram?

Based on our AAOIFI-standard shariah screening, CSGP is Halal and considered permissible for Muslim investors. It passed all 4 of 4 compliance screens including business activity review, debt-to-market-cap ratio (7.51% vs ≤33% threshold), interest income ratio (3.39% vs ≤5% threshold), and cash & securities ratio (11.37% vs ≤33% threshold).

CoStar Group, Inc. is a leading provider of information, analytics, and online marketplaces for the commercial real estate industry. Through platforms like CoStar Property and CoStar COMPS, the company offers robust databases tracking property inventory, sales transactions, and market trends across global markets. For Muslim investors, CSGP represents a fully compliant opportunity in the real estate services sector. The stock successfully passes all four AAOIFI screening criteria, meaning its core business operations and financial structures align with Islamic finance principles. From a financial perspective, CoStar Group is highly attractive for halal portfolios due to its conservative use of leverage, boasting a debt-to-market cap ratio of just 7.5%. While the company earns some interest income at 3.39% of total revenue, this remains comfortably below the strict 5% AAOIFI threshold. Since the company operates within permissible real estate analytics, there is little scholarly debate regarding its core operations. However, Muslim investors should continue to monitor its interest income levels to ensure they do not exceed the 5% limit as interest rates fluctuate. CoStar Group, Inc. operates in the Real Estate sector under the Real Estate - Services industry and is headquartered in Arlington, VA, US. The company is led by CEO Andrew C. Florance and employs approximately 8,441 people.

CSGP was screened using AAOIFI-based shariah compliance criteria. Four tests are applied: (1) Business Activity — the company's core business must not derive primary income from haram (prohibited) activities such as alcohol, gambling, tobacco, or interest-based finance. (2) Debt-to-Market-Cap — total debt must not exceed 33% of market capitalization. (3) Interest Income — interest income must not exceed 5% of total revenue. (4) Cash & Securities — cash and interest-bearing securities must not exceed 33% of market cap. CSGP passed 4 of these 4 screens.

Although CSGP passes all shariah screens, it does earn $110.0M in interest income (3.39% of revenue). Many scholars recommend purifying this portion by donating the equivalent percentage of any dividends received to charity. For example, if you receive $100 in dividends, you would donate approximately $3.39 to purify the income.
