In January the split ran the other way: Wildberries accounted for 57.54% of sales and Ozon for 42.46%, the study found.
The shift also affected smaller vendors. Among businesses in the bottom quarter of the sample, about 59% of sales fall to Ozon and 41% to Wildberries. Ozon also leads in the middle groups, with a share of roughly 55–59%.
Since the summer, Ukrainian drones have attacked Wildberries warehouses in various Russian regions, and since August also Ozon logistics complexes. Ukraine said the sites are used in supplies of sanctioned components for the production of drones and navigation equipment. Damage to Wildberries and its sellers from the strikes was estimated at hundreds of billions of rubles as of early August.
According to an estimate by the advertising agency Mafia Agency, the summer logistics disruptions hit Wildberries especially hard: sellers ran into problems with product availability and delivery times and began redistributing resources between platforms. Sales were also affected by assortment, prices, advertising and marketplace terms.
In August–September, Wildberries' daily reach fell by 10% while Ozon's rose by 26%, Kommersant reported earlier. Advertising activity on Wildberries in July dropped by 63% compared with June.
The combined Wildberries and Russ company said the study does not reflect the full picture of the market and does not take into account the specifics of how different categories of sellers operate. According to its data, sales figures for large sellers on Wildberries remain stable and may show only minor fluctuations. Ozon did not respond to a request for comment.
