Market Insights Snapshot
In May 2026, Oleum Extracts (Oleum Labs) derived 50.23% of sales from Vapor Pens and 37.35% from Concentrates, with Pre-Roll contributing 12.43%; within that mix, Vapor Pens grew 6.11% year over year but fell 5.52% month over month, while Concentrates declined 4.46% year over year but rose 16.89% month over month. Pre-Roll contracted 26.18% year over year yet ticked up 3.95% month over month, and the brand’s average price was up 3.48% year over year alongside an overall brand sales decline of 3.15% year over year; the thesis is that the category balance is pivoting toward Concentrates momentum intra-month while Vapor Pens still anchor share but softened sequentially.
Positioning-wise, a 21 rank in Vapor Pens in Washington combined with a 5.52% month-over-month dip in that category suggests headroom to trade mix toward Concentrates, where a 16.89% month-over-month gain can offset Vapor Pens’ sequential softness and mitigate the 1.97% 24-month sales decline. With Pre-Roll at only 12.43% share and down 26.18% year over year, the brand can concentrate price/assortment moves where elasticity is working—as evidenced by a 3.48% year-over-year price increase coexisting with a 6.11% Vapor Pen year-over-year lift—implying the near-term path is to defend Vapor Pen rank while leaning into Concentrates to stabilize total sales trajectory.
Competitive Landscape
In Washington Vapor Pens for May 2026, Oleum Extracts (Oleum Labs) sits at rank #21, a 2-position improvement from #23 year over year, but down 3 spots from #18 in February 2026, indicating recent quarter-on-quarter slippage despite the YoY gain; the brand’s peak was #14 in September 2025, placing it 7 ranks above today’s position. Among competitors, Mfused held #1 both this year and last year while recording a -22.29% YoY sales change, and Full Spec climbed from #5 to #3 with +13.70% YoY growth, suggesting Oleum’s modest 2-rank YoY advance is outpaced by upward movers while laggards at the top are not translating into share capture for Oleum; the trajectory implies Oleum needs near-term rank gains of 3–7 positions to re-close the gap to its September 2025 ceiling and convert competitor volatility into sustained placement.
Notable Products
Wedding Cake Live Resin Cartridge (1g) delivered the headline move in May 2026 with a +90.4% month-over-month surge to rank 1, while Gorilla Glue #4 Honey Crystal (1g) slipped -9.1% to rank 4. Pre-Roll SKUs occupy four of the top ten positions (ranks 2, 5, 6, 7, and 8), indicating breadth in infused formats even as Vapor Pens bookend the chart at ranks 1 and 9. The concentration of Pre-Rolls alongside a top-ranked Vapor Pen implies Oleum Extracts (Oleum Labs) is tilting toward inhalable convenience formats where rapid velocity can offset softness in select concentrates.
