Market Insights Snapshot
Eureka’s May 2026 mix is overwhelmingly concentrated in Vapor Pens at 99.39% share, where sales were down 19.38% year over year but up 15.86% month over month, while Concentrates held 0.32% share with a 210.84% year-over-year increase but a 19.15% month-over-month decline. Flower accounted for 0.29% share with a 76.17% year-over-year drop and a 24.82% month-over-month decline, and the brand’s average price fell 7.21% year over year to $32.74. With Vapor Pens anchoring rank 9 in Colorado and the non-core categories shrinking in both share and near-term momentum, the pattern implies Eureka is doubling down on a single-category strategy that lifts short-term volume but leaves year-over-year exposure concentrated where declines persist.
The combination of a 15.86% month-over-month rebound in Vapor Pens alongside a 7.21% decline in average price suggests volume-led recovery, but the 19.38% year-over-year drop in that same category and a 20.01% brand-level year-over-year sales decline indicate price and mix are not offsetting annual headwinds. With Concentrates up 210.84% year over year off a 0.32% share base and Flower down 76.17% year over year at 0.29% share, diversification is too small to shift positioning, so maintaining rank 9 in Colorado hinges on defending Vapor Pens while selectively scaling the highest-velocity niches to reduce reliance on a single category.
Competitive Landscape
Eureka sits at rank #9 in CO Vapor Pens in May 2026 with no year-over-year rank change from #9, but it improved 3 positions versus February 2026 when it was #12, suggesting short-term momentum despite a flat annual position; meanwhile, Spherex held at #1 year over year while contracting by 14.1% in sales, and PAX climbed from #3 to #2 with 24.0% sales growth, indicating that Eureka’s stable #9 is occurring as leaders shuffle above it. With Bonanza Cannabis Company sliding from #2 to #4 alongside a 46.5% sales decline and Spectra jumping from #14 to #5 on 135.3% growth, the competitive set is volatile while Eureka remains anchored at #9; given a historical peak of #3 in October 2024 and a recent quarter-to-date gain of 3 ranks, the trajectory implies a pathway to re-enter the top 5 if near-term share gains persist against weakening incumbents.

Notable Products
Classic - Mango Haze Distillate Reload Disposable Pod (1g) posted the largest month-over-month jump at 63.5% while climbing to rank 3, and Classic - Triple Diesel Distillate Reload Pod (1g) advanced 40.1% at rank 1, indicating demand is concentrating in reloadable formats rather than disposables. With Cherry Gelato Distillate Reload Pod (2g) up 41.6% at rank 4 and seven of the top ten being Vapor Pens reload pods, the mix tilts toward larger or refillable units over single-use items. The lone disposable called out, Classic - Blackberry Kush Distillate Disposable (1g), grew 17.9% at rank 7 against the higher double-digit gains in reload pods, suggesting relative share migration toward pods even as disposables still move $32,136 in May 2026. The pattern implies Eureka is winning by leaning into reload ecosystems and higher-capacity SKUs, which can compound repeat purchase behavior and stabilize share across ranks 1–5.

Data for this report comes from real-time sales reporting by participating cannabis retailers via their point-of-sale systems, which are linked up with Headset’s business intelligence software. Headset’s data is very reliable, as it comes digitally direct from our partner retailers. However, the potential does exist for misreporting in the instance of duplicates, incorrectly classified products, inaccurate entry of products into point-of-sale systems, or even simple human error at the point of purchase. Thus, there is a slight margin of error to consider. Brands listed on this page are ranked in the top twenty within the market and product category by total retail sales volume.
