The Maze: Temu has reached the top three in four Eastern European markets. Yet third place in Poland and first place in Hungary describe very different competitive positions. ECDB's 2025 estimates put Allegro at €14.4bn in Polish gross merchandise value, the value of goods sold, versus Temu's €1.8bn. In Hungary, Temu leads at €1.1bn. A regional expansion plan needs more than a list of podium finishes. It needs the distance between the platforms on that podium.
Poland separates access from dominance. Allegro's €14.4bn is eight times Temu's €1.8bn using the rounded GMV figures. Media Expert, an electronics retailer, sits between them at €2.4bn. Temu is already a substantial shopping destination, but its third-place position does not mean the leader is within easy reach. For a brand deciding where to build distribution, the ranking establishes relevance; the size gap establishes a different level of commercial weight. Third place is a foothold, not a forecast of first place.
The two Alza markets need separate plans. Electronics retailer Alza.cz leads Czechia at €2.4bn, ahead of Temu's €1.1bn and online grocer Rohlik.cz's €0.7bn. In Slovakia, Alza.sk leads at a rounded €0.7bn, followed by Temu at €0.4bn and AliExpress at €0.3bn. Both Alza storefronts are first, and both Temu businesses are second. Those identical positions hide different absolute distances. The Czech lead over Temu is roughly €1.3bn; Slovakia's is roughly €0.3bn on the displayed values. Neither gap tells us how fast it will close. It does tell an operator why a shared rank is a poor substitute for a country budget.
Hungary reverses the incumbent story. Temu takes first place at €1.1bn, followed by eMAG at €0.5bn and AliExpress at €0.4bn. Two Chinese cross-border platforms occupy the top three, as they also do in Slovakia. In Poland and Czechia, each country's top three includes only Temu from that pair. That is a difference in competitive composition, not proof that cross-border sellers control most spending. The twelve listed entries are selected retailers, not the entire market. Brands can use the mix to choose whom to benchmark on price, delivery and assortment; they cannot use it as a market-share denominator.
A podium is not a profit statement. Ecommerce intelligence provider ECDB combines transactions, disclosures, traffic and modeling in its measurement approach. Marketplace GMV includes third-party seller volumes, so it is different from the platform's own revenue. The estimates also do not expose retailer margins or acquisition costs. Alza.sk illustrates the precision limit: the source article gives €655m while the ranking rounds it to €0.7bn. Preserve the vintage and rounding before calculating gaps. A smaller GMV lead can justify closer monitoring; it cannot establish that a rival will overtake next quarter or that the leader's economics are weak.
Why it matters: Eastern Europe is a geography, not a single competitive condition. Build the country plan around the incumbent's scale, the challenger mix and the service promise a shopper can actually use. Then measure whether price pressure changes conversion or margin in your own categories. The 2025 ranking sets a benchmark for that work. It does not supply a 2026 growth rate, a takeover date or a reason to copy one market's spending plan into the next.
