3 Top Marijuana Stocks to Watch in September 2026
Marijuana stocks continue to attract attention as investors search for opportunities across the evolving United States cannabis industry. September 2026 could bring additional interest as traders digest fresh earnings reports and operational developments. However, cannabis stocks remain volatile, making research especially important before entering the sector. Several operators still face price compression, high expenses, debt, and difficult financing conditions. Nevertheless, stronger companies continue improving efficiency while concentrating resources in their most promising markets. Additionally, regulatory developments remain an important potential catalyst for the broader cannabis industry. Investors are also examining second-quarter results for evidence of improving margins, stronger production, and healthier cash flow. Consequently, companies demonstrating operational progress could attract increased attention throughout September. Planet 13 Holdings, Glass House Brands, and FLUENT Corp. represent three very different cannabis opportunities. Each company carries unique strengths, risks, and financial challenges. Therefore, understanding their latest developments is important before considering these marijuana stocks.
Watch for Potential Upside in September
Planet 13 continues building its Florida medical marijuana presence while maintaining established operations in Nevada and Illinois. Meanwhile, Glass House Brands has increasingly focused on large-scale cultivation and wholesale cannabis production in California. The company recently reported record quarterly biomass production alongside meaningful sequential improvements in profitability. FLUENT Corp. offers another cannabis story for investors watching September trading. Florida remains FLUENT’s largest retail market, while the company maintains operations in New York and Texas. FLUENT continues navigating declining revenue, pricing pressure, debt, and strategic changes across its operating footprint. The company is working toward completing its proposed transaction with Vireo Growth. These businesses represent different approaches to competing in America’s cannabis market. Planet 13 emphasizes expansion, while Glass House concentrates heavily on efficiency. FLUENT remains focused on cost reductions and improving its financial position. Therefore, PLNH, GLAS, and CNTMF are marijuana stocks worth watching closely during September 2026.

3 Cannabis Stocks That Could Make a Move This September
- Planet 13 Holdings Inc. (OTC: PLNH)
- Glass House Brands Inc. (OTC: GLAS)
- FLUENT Corp. (OTC: CNTMF)
Planet 13 Holdings Inc. (PLNH)
Planet 13 Holdings is a vertically integrated cannabis company operating in Florida, Nevada, and Illinois. Florida has become the company’s largest market, driven by its expanding dispensary footprint. Planet 13 significantly increased its presence there after acquiring VidaCann during 2024. That transaction initially brought 26 Florida dispensaries into the company’s growing retail network. Furthermore, Planet 13 continued expanding after completing the acquisition. The company had 33 Florida medical marijuana dispensaries at the end of June 2026. Additionally, Planet 13 opened its Sarasota dispensary on August 21, further expanding its statewide presence. Outside Florida, the company operates its famous Planet 13 SuperStore and Medizin dispensary in Las Vegas. Planet 13 also maintains a dispensary in Waukegan, Illinois. Consequently, Florida remains the centerpiece of the company’s current retail expansion strategy. Continued store development could strengthen brand recognition and, over time, give Planet 13 greater exposure to Florida’s large medical cannabis market.
Latest Financials
Planet 13 reported second quarter 2026 revenue of $22.9 million, representing a 14.9% decline from the previous year. However, revenue increased 8.4% sequentially compared with the first quarter. Furthermore, Florida revenue increased 17.1% quarter over quarter, showing improving momentum within the company’s most important retail market. Gross profit reached $12.3 million during the quarter. Meanwhile, gross margin improved to 53.9%, compared with 43.4% during the previous year’s period. Planet 13 reported a net loss of approximately $5.6 million. Nevertheless, that was considerably better than the $13.3 million loss reported one year earlier. Adjusted EBITDA remained negative at $500,000. However, that improved from a $2.4 million adjusted EBITDA loss during the comparable period. Planet 13 finished June with $16.5 million in cash and restricted cash. Therefore, improving margins, sequential revenue growth, and stronger Florida performance could make PLNH an interesting marijuana stock to watch closely throughout September 2026 for cannabis investors.

Glass House Brands Inc. (GLAS)
Glass House Brands is a California cannabis producer specializing in large-scale greenhouse cultivation, manufacturing, and wholesale distribution. California remains the company’s primary operating market and the center of its production platform. Historically, the company also controlled a portfolio of retail dispensaries in California. Its former retail network included Farmacy, Natural Healing Center, and The Pottery locations. Altogether, that business consisted of 10 stores before the company’s structural changes.
However, Glass House completed the deconsolidation of its retail business in June. As a result, those dispensaries are no longer consolidated in the company’s financial statements. Instead, Glass House has increasingly concentrated on medical cannabis cultivation, processing, manufacturing, and wholesale production. Additionally, its shares began trading on the New York Stock Exchange under GLAS in June. Consequently, investors should now focus on production efficiency, wholesale demand, margins, and cultivation growth.
Latest Financials
Glass House Brands reported second-quarter 2026 revenue of $47 million from continuing operations. That compared with $47.6 million during the previous year’s quarter. However, revenue improved considerably from $28.6 million during the first quarter of 2026. Wholesale biomass generated $41.7 million, accounting for approximately 89% of total quarterly revenue. Additionally, Glass House produced 245,746 pounds of cannabis biomass during the quarter. That increased significantly from 151,531 pounds during the previous quarter.
Meanwhile, production costs improved to approximately $122 per pound from $175 during the first quarter. Gross profit reached $15.8 million, while gross margin came in at 34%. Adjusted EBITDA was positive at $5.7 million. That represented a substantial improvement from a $4.2 million loss during the first quarter. Furthermore, Glass House ended June with $22.1 million in cash, restricted cash, and cash equivalents. Consequently, stronger production efficiency and sequential improvements make GLAS particularly worth monitoring throughout September 2026 trading.

The company cultivates, manufactures, distributes, and sells cannabis products through consumer brands. Its portfolio includes MOODS, Knack, Wandr, Bag-O, and Hyer Kind. Florida represents FLUENT’s largest market by retail footprint and remains central to its operating strategy. At June 2026, FLUENT operated 34 retail locations across Florida, New York, and Texas. Florida accounted for 32 stores and four production facilities at that time. Additionally, the company opened another Florida dispensary in Palm Bay during July 2026. New York contributed one retail location and two production facilities during the second quarter. Meanwhile, FLUENT entered an agreement to sell its Texas operations, subject to regulatory approval and closing conditions. Consequently, Florida remains the company’s largest retail market. Investors should closely watch whether store optimization and ongoing cost reductions improve performance in the second half.
Latest Financials
FLUENT reported second-quarter 2026 revenue from continuing operations of $17.1 million, compared with $22.8 million one year earlier. Florida generated $12.8 million of that revenue, compared with $19.2 million during the prior year period. Additionally, gross profit before fair value adjustments totaled $4.3 million, representing 25.2% of revenue. That compared with $8.9 million and 38.8% of revenue the prior year. Adjusted EBITDA fell to $300,000 from $3.6 million as Florida retail pricing remained under pressure. Nevertheless, operating cash flow remained positive at approximately $800,000 during the quarter. FLUENT finished June with approximately $4.5 million in cash and cash equivalents. However, total debt stood at approximately $79.7 million, highlighting the company’s financial challenges. Management continues to reduce costs, optimize its Florida footprint, and pursue the proposed Vireo transaction. Therefore, CNTMF remains a higher-risk marijuana stock that could attract significant investor attention as investors monitor liquidity, restructuring efforts, and operational improvements.
