Market Insights Snapshot
Diamond Science concentrated 93.996% of October 2026 sales in Vapor Pens with a 90.497% month-over-month lift, while Edible held 6.004% share with a -9.878% MoM decline; year-over-year, Vapor Pens expanded by 18,833.528% alongside a -11.070% YoY drop in overall average price. Despite a 20,042.936% YoY surge in brand sales, the Vapor Pens average price sat at $35.88 against a brand-wide $29.30, indicating mix-driven pricing dynamics, and the brand ranked 47 in Vapor Pens within Illinois. The pattern implies a single-category engine is accelerating volumes at lower unit prices, compressing blended pricing while deepening reliance on Vapor Pens momentum.
With Vapor Pens now shouldering 93.996% share and rising 90.497% MoM as Edible contracts -9.878% MoM, the mix tilts further toward a higher-priced flagship where category rank is 47 in Illinois, yet the brand’s -11.070% YoY average price shift signals elasticity rather than premium consolidation. The juxtaposition of 18,833.528% YoY category growth in Vapor Pens and a 6.004% Edible share that lacks YoY history implies positioning as a volume-first Vapor Pens player with limited diversification, making future stability contingent on sustaining Vapor Pens velocity while selectively testing Edible to reduce single-category risk.
Competitive Landscape
Diamond Science sits at rank #47 in Illinois Vapor Pens as of October 2026, up 7 positions from #54 in July 2026, while year-over-year rank change is unavailable and thus the relevant comparison is a 13.0% climb in rank position relative to the top-50 threshold and a peak alignment with its best-ever #47 also recorded in October 2026. In contrast, Select holds #1 with a +2 YoY rank move and +16.1% YoY sales, and Fernway advanced to #2 with a +10 YoY jump and +222.0% YoY sales, indicating that Diamond Science’s modest rank ascent over three months trails leaders’ multi-period gains and implies a trajectory centered on incremental share capture rather than top-tier displacement.
Notable Products
Diamond Science leans on recent launches in October 2026, with new products accounting for 68.5% of sales and filling 8 of the top 10 spots. Headband Live Resin Disposable (2g) and Cosmic Gelato Live Resin Disposable (2g) alone contribute 30.0%, so most of its sales come from very recent items.

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.
