What Are the Biggest Cannabis Companies?

The cannabis industry is home to several large publicly traded companies, though even the biggest cannabis operators are small compared to companies in more established sectors. Understanding the landscape of major cannabis companies helps investors identify potential opportunities and benchmark performance.

Among US multi-state operators (MSOs), the largest companies by revenue include Curaleaf Holdings (CURLF), which operates in approximately 20 states with over 100 dispensaries and generates over $1.3 billion in annual revenue. Green Thumb Industries (GTBIF) operates in 15 states with its RISE dispensary brand and is widely regarded as the best-managed MSO, with consistent profitability and positive free cash flow. Trulieve Cannabis (TCNNF) dominates the Florida market, generating the majority of its revenue from a single state while expanding operations elsewhere. Verano Holdings (VRNOF) and TerrAscend (TSNDF) round out the top tier of US operators.

Canadian licensed producers represent the other major segment of publicly traded cannabis companies. Tilray Brands (TLRY) is the largest LP by revenue, having merged with Aphria and diversified into craft beer, spirits, and wellness products. Canopy Growth (CGC) was once the highest-valued cannabis company globally after receiving a $4 billion investment from Constellation Brands but has struggled with execution and cash burn. SNDL (SNDL) and Organigram (OGI) are other notable Canadian operators that have found varying degrees of success.

Ancillary companies — those that serve the cannabis industry without directly touching the plant — include some of the largest cannabis-related businesses by market capitalization. Scotts Miracle-Gro (SMG) is a Fortune 500 company whose Hawthorne Gardening subsidiary is a major supplier of cultivation equipment. GrowGeneration (GRWG) operates the largest chain of hydroponic supply stores in the US. These companies benefit from cannabis industry growth while avoiding the regulatory risks associated with plant-touching operations.

Beyond publicly traded companies, several large private operators are notable. Companies like Columbia Care (acquired by Cresco Labs), Ascend Wellness, and various single-state operators control significant market share in their respective territories. The cannabis industry is likely to see continued consolidation as larger operators acquire smaller competitors, regulatory barriers fall, and the industry matures toward a structure more similar to traditional consumer packaged goods markets.
