Reporting correction: The headline growth figure comes from Shopify’s comparison of September 2025 with 2024 among US Shopify merchants. It is not a fresh measurement of all 2026 ecommerce sales.
Every year a few product categories explode out of nowhere, and Shopify’s published category comparison provides a dated snapshot of fast-growing products. Some of the numbers are hard to believe. Creatine sales grew by roughly 1,862 percent. Satchel bags jumped 1,771 percent. Here is a tour of the products quietly taking over online shopping carts.
The Fitness Supplement Gold Rush
Creatine’s near 1,900 percent growth is the headline story. Once a niche bodybuilding supplement, it has gone fully mainstream, with the sales data measuring purchasing activity rather than establishing health benefits. Collagen is on a similar tear with about 1,569 percent growth, in the same comparison. The wellness economy keeps finding new gears, and supplements are its fastest lane.
Fashion’s Unexpected Winners
On the fashion side, satchel bags are the breakout accessory with growth over 1,700 percent. Barrel fit jeans have seen a 500 percent rise in search interest, while overshirts posted a 166 percent sales increase. Even sweatpants revenue has doubled. In the same September 2025 growth table, puffer jackets recorded 849 percent growth; they should not be described as declining within that dataset.
Wheels and Caffeine
Electric motorcycles and scooters grew around 1,730 percent as commuters keep looking for cheaper ways to get around. Instant coffee, of all things, posted 842 percent growth, driven by premium instant brands that made the category cool again. And in the collectibles corner, sports trading cards continue their renaissance as both a hobby and an investment play.
The Steady Giants
Beyond the explosive growers, the biggest categories remain familiar: t-shirts are still the top selling clothing item online, skincare keeps expanding, and vitamins hold their ground. One odd standout inside skincare: searches for beef tallow as a moisturizer jumped 2,600 percent over two years, one of the stranger beauty trends in recent memory. Car accessories are climbing too, with dashboard gadgets up 140 percent and dash cams pulling over one hundred thousand searches a month.
How to Read These Numbers
Triple and quadruple digit growth usually means one of two things: a genuine shift in consumer behavior or a viral spike that will fade. Supplements and electric transport look like durable shifts backed by long term trends in health and cost of living. Some fashion spikes will cool by next season. For anyone selling online, the smart move is to ride the wave early but never build an entire business on a single viral product.
How to read a dramatic growth percentage
A growth percentage needs its base and measurement window. A category growing rapidly from a small starting point can still be smaller than a slower-growing established category. Without absolute sales and the scope of the sample, ranking by percentage alone cannot identify the largest commercial opportunity.
Shopify’s dataset is useful for observing activity among its merchants. It should not be extended to all online shops, every marketplace or a whole national economy. A list framed around 2026 can still contain figures collected earlier; the reporting period must remain visible when the number is quoted.
A seller considering one of these categories should compare its own unit economics before making an inventory decision. Shipping weight, breakage, returns, customer support and repeat purchasing can change the appeal of two products with similar growth rates. A high-growth item with difficult fulfilment may be less practical for a small store than a steadier category it understands.
For a reader buying a product, popularity is not a quality score. This is particularly relevant to supplements: sales growth does not demonstrate a health outcome or identify a suitable choice for an individual. The value of this report is its dated commercial snapshot, not a recommendation to buy every category that appears in a growth table.
