Market Insights Snapshot
Kolab concentrated almost entirely in Vapor Pens during May 2026, with Vapor Pens holding 98.50% share and posting a 3.14% month-over-month lift despite a 0.76% year-over-year dip, while Pre-Roll rose 25.09% MoM but sat at just 1.20% share after a 65.30% YoY decline. Minor lines contracted sharply, with Concentrates down 44.79% MoM and 94.01% YoY at 0.26% share, and Flower up 11.47% MoM but down 99.08% YoY at 0.05% share; alongside a 14.12% YoY drop in average price to $34.46, the mix implies volume defense in the core and strategic deprioritization of fringe categories.
The category tilt supports a positioning anchored in Vapor Pens where Kolab holds a rank of 5 in British Columbia, suggesting focus on depth over breadth as Pre-Roll’s steep 65.30% YoY contraction and Concentrates’ 94.01% YoY pullback limit cross-category reach. With Vapor Pens gaining 3.14% MoM share momentum and the brand’s overall sales down 11.07% YoY while 24-month growth stands at 48.61%, the pattern points to a scale-maintenance strategy centered on pen volumes at lower price points, accepting reduced presence in smaller categories to reinforce a single-category identity in ON.
Competitive Landscape
Kolab is ranked #10 in ON Vapor Pens in May 2026, down 1 place year over year from #9, and up 8 places versus February 2026 when it sat at #18; the brand’s peak of #8 in July 2025 sets a reference point that is 2 ranks above today. Competitive context is shifting: Spinach climbed from #6 to #2 with a 137.7% year-over-year sales increase, while BoxHot slid from #2 to #3 alongside a 33.4% sales decline, and category leader Back Forty / Back 40 Cannabis held #1 with a 3.7% gain. The mix of Kolab’s modest YoY rank drop (−1) and recent 3-month rebound (+8) implies a mid-pack recovery path where recapturing the #8 peak will depend on sustaining quarter-over-quarter momentum against faster risers like Spinach and taking share from brands with negative growth trajectories like BoxHot.
Notable Products
Blue Passionfruit Diamonds FSE Cartridge (1g) delivered the standout move in May 2026 with a 100.2% month-over-month surge to rank 3, while Guava OG Diamonds FSE Cartridge (1g) collapsed by 60.9% to rank 10. Pink Lychee Diamonds Distillate Cartridge (1g) slid 23.1% while holding rank 1, and Strawberry Ice Diamonds Distillate Cartridge (1g) fell 14.8% at rank 2. With eight of the top ten in Vapor Pens and Pure Liquid Diamonds Disposable (1g) up 57.1% at rank 5, the mix points to a pivot toward higher-velocity pen formats where FSE and disposables are gaining share at the expense of older distillate variants.
