Booking Holdings and Expedia Group control 85% of Europe's online travel agency market, according to a new study reported by Hotel News Resource. That single figure frames the distribution reality for most European hotel operators: two US-listed groups sit between them and a large share of their guests.

The number matters because it puts hard data on what hoteliers have argued for years. When four out of five online bookings flow through two platforms, the negotiating position of an individual property shrinks. Commissions, rate-parity terms and listing visibility all get set by platforms that hotels can't realistically refuse.

Why does one number change the conversation?

A market share figure like this gives regulators and trade bodies something to work with. European hotel associations have pushed the EU to scrutinise OTA practices for years, citing parity clauses and commission levels as constraints on independent operators. An 85% concentration reading strengthens the case that the sector isn't functioning as a competitive market.

For hoteliers, the study confirms that direct-booking campaigns aren't just marketing talk. Every point of share shifted to brand websites is a point that escapes the commission structure of the two dominant intermediaries.

What does this mean for European operators?

The practical effects show up in three places:

• Commission costs. Independent hotels and small chains typically pay the highest rates, since they lack the volume leverage of branded groups.
• Rate parity. Hotels remain constrained in how they price their own channels relative to the OTAs that carry most of their demand.
• Visibility dependence. A property that loses placement on one of the two platforms can see a material drop in bookings, given how concentrated the demand side is.

Larger brands have partly insulated themselves through loyalty programmes and direct-channel investment. Smaller properties don't have that buffer, which is why concentration figures tend to hit the independent segment hardest.

What happens next?

The study lands at a moment when EU competition policy is already examining digital gatekeepers and platform practices across sectors. A documented 85% share for two operators gives hotel associations a concrete data point to bring to Brussels, and gives investor presentations at both Booking and Expedia a clear picture of their entrenched position in the region. Expect further filings and lobbying from European hospitality bodies citing the figure as evidence for tighter platform rules; operators will be watching whether regulators treat the finding as grounds for a formal review of parity clauses.
