Market Insights Snapshot
Fathom Cannabis has shown a notable performance in the Massachusetts market, particularly in the Pre-Roll category. The brand has consistently improved its ranking, moving from 36th place in September 2025 to 23rd in November 2025, before slightly dropping to 26th in December 2025. This upward trajectory in rankings reflects a strengthening presence in the market, which is further supported by a steady increase in sales over the months. Conversely, the Flower category tells a different story, where Fathom Cannabis was not in the top 30 brands until December 2025, when it reached 77th place. This delayed entry into the rankings suggests potential challenges or a slower growth pace in this category compared to Pre-Rolls.
The Pre-Roll category's performance is particularly impressive given the competitive nature of the cannabis market in Massachusetts. The ability to climb rankings over a short period indicates effective market strategies or product offerings resonating well with consumers. However, the absence of Fathom Cannabis from the top 30 in the Flower category for several months could be a point of concern, suggesting that the brand may need to reassess its approach or offerings in this segment. The contrast in category performance highlights the importance of targeted strategies to cater to varying consumer preferences and market dynamics.
Competitive Landscape
In the Massachusetts Pre-Roll category, Fathom Cannabis has shown a dynamic performance in the latter months of 2025. Starting from a rank of 36 in September, Fathom Cannabis improved to 26 by October, climbing further to 23 in November, before slightly dropping to 26 in December. This fluctuation indicates a competitive market landscape where brands like INSA and Green Gold Group are also vying for top positions. Notably, INSA and Green Gold Group have maintained a stronger presence, with Green Gold Group consistently ranking higher than Fathom Cannabis, despite a sales decline in December. Meanwhile, Smyth Cannabis Co. has shown a steady improvement, closing the year with a rank of 28, which could pose a challenge to Fathom Cannabis if the trend continues. The competitive shifts highlight the need for Fathom Cannabis to strategize effectively to maintain and improve its market position amidst strong contenders.
