Telecom market concentration is increasing in each of the 27 EU member states.

No official BEREC, Eurostat or European Commission dataset was found that reports rising HHI/concentration ratios for all 27 member states individually; the universal 'each of the 27' formulation is not documented in any source found.
The trend is documented by commercial telecoms research (Analysys Mason) as happening in 'many' European countries, not in all 27, and the same source notes counter-movements (new fourth entrants in some markets, stagnant MVNO share).
Only a single independent secondary source explicitly supports the consolidation trend; no primary regulator data (BEREC market reports, national regulatory authority HHI data) could be located.
The evidence found pre-dates the 2026-10-20 session and concerns the 2015–2025 period; no 2026 data on per-country concentration was retrievable.

SecondaryAnalysys Mason — 'Europeans may soon have three major MNOs per country'"The number of MNOs is falling in many European countries"; "The share of Europeans that live in a country with fewer than four MNOs is expected to grow from 46% in 2015 to 56% by the end of 2025"; "MVNOs across Europe have mostly failed to increase their market share. Their share of mobile connections grew marginally, to around 10%, in the period from 2015 to 2024."; "By 2025, the number of MNOs will have increased from three to four in just three countries: Belgium, Germany and Portugal."
SecondaryOokla — 'Is Telecoms Consolidation the Panacea for Europe's Digital Competitiveness?'"A central tenet of the Draghi report is that the bloc's fragmented telecoms market—a morass of dozens of small operators compared to just a handful in similarly sized regions elsewhere—has triggered a race to the bottom in pricing, eroding profitability"; "countries, greater market concentration is associated with lower capital intensity per operator, as larger players may face reduced incentives to invest."
