7 Categories on the Rise on Trendyol in 2026
What does the data say? We break down the categories whose demand is booming this year while competition stays low — and how to position yourself.
2026 turned out to be a year of recalibration for Turkish marketplaces. As post-pandemic demand normalized, where consumers spend their money shifted fast. Using Bu Gider data, we examined the seven categories on Trendyol whose unit sales grew fastest over the past six months while competition stayed manageable.
These categories rest on real metrics — monthly unit sales, the pace of review growth and active-seller density — not on guesswork. For each, we share how you should position yourself.
1. Smart home and energy savings
Rising energy costs turned smart plugs, motion-sensor lighting and thermostats from a luxury into a necessity. Review counts here climbed about 40% last quarter, yet more than half of the listings have weak quality. A clear, benefit-led title and the right imagery can still land you on the first page.
2. Home office and ergonomics
As hybrid work becomes permanent, demand for adjustable desks, lumbar cushions and monitor risers keeps growing steadily. The winner here sells the solution, not the product: 'end back pain' converts far faster than 'metal-legged stand.'
3. Sustainable and reusable products
- Bamboo kitchenware and organizers
- Reusable food-storage solutions
- Refillable cleaning products
Margins in these sub-niches can exceed 45% because shoppers willingly pay extra for perceived 'value.' Validating low-competition keywords with the Index Checker is the quickest way to lock in your visibility early.
4. Pet tech
Automatic feeders, smart water fountains and GPS collars have climbed sharply in owners' spending priorities. Despite high review volume, there are few quality sellers — a clear gap for new entrants.
The remaining three categories and the common lesson
The list continues with personal-care devices, hobby & craft supplies and travel accessories. All three are exposed to seasonal swings, but caught with the right timing they can multiply revenue in a short window.
By the time a category is 'trending,' most sellers are already late. The real gains go to those who move the moment the data shows the curve.
The takeaway is clear: windows of low competition and high demand are short. Find the opportunity with Product Research, validate the margin with the Commission Calculator, then track and scale. Move with data, not guesswork.
