Less than a week after Brussels handed Google its first Digital Markets Act penalty, the company’s competitors are already turning the ruling into ammunition.

The European Commission fined Google €890mn on 23 July, roughly $1bn at current rates, and the rivals who have spent years chasing the search giant through European courts now see the infringement finding as fresh leverage in a fast-growing pile of private damages claims.

The fine itself splits into €460mn for favouring Google’s own shopping results over those of competitors and €430mn for stopping app developers from steering users away from Google Play.

It was the penalty Brussels had spent months preparing, and it lands on a company already carrying a record €4.1bn Android fine and more than €10bn in earlier European antitrust penalties.

What makes the decision valuable to rivals is not the money going to Brussels but the precedent going into their own cases.

Under EU rules a Commission infringement finding can underpin follow-on damages actions, which lets claimants argue that liability is effectively settled and then fight only over how much they are owed.

Lawyers expect the ruling to reinforce claims already grinding through national courts, and Thomas Hoppner of Geradin Partners, a firm that has acted for several of the complainants, predicted it would *“trigger a new wave of litigation.” *

The value lies in scale as much as substance, since a claimant no longer has to prove that Google broke the rules before it can argue about the cost.

Several of those cases are well advanced. In Germany, the price-comparison site Idealo won €465mn, about $529mn, from a Berlin court in November, in a claim rooted in Google’s search self-preferencing.

Sweden’s PriceRunner, which is owned by Klarna and filed its suit back in 2022, secured an even larger award this month when a Stockholm court ordered Google to pay around $1.5bn, or close to $1.97bn once interest is added. Google is expected to appeal, and the case could run for more than another year.

Others are still being built. Italy’s Moltiply, which owns the Trovaprezzi.it shopping platform, is seeking €2.97bn, while in the Netherlands two groups backed by the litigation funder LitFin are pursuing more than $1bn between them.

Most of these actions trace back to the Commission’s 2017 Google Shopping decision, a €2.42bn penalty that first established the self-preferencing pattern the new DMA finding now echoes.

The clearest sign of how much the ruling matters is Google’s effort to keep it out of court. Before the UK Competition Appeal Tribunal, where Kelkoo, Foundem, and Connexity are pursuing a multibillion-pound claim, Google has asked judges to exclude the DMA decision from the evidence, arguing that the regulation rests on a different legal framework from the competition-law claims at issue.

The company says the finding is both inadmissible and irrelevant.

Google has given little ground publicly. Kent Walker, its president of global affairs, called the Commission’s decision the work of “a small group of self-serving complainants” and said the company was reviewing an appeal, even as it faces 60 days to redesign its search results and open up app steering, with non-compliance carrying daily fines of up to 5% of Alphabet’s global turnover.

The competition chief Teresa Ribera framed it more plainly, saying the best products “should succeed because they’re better, not because they’re owned by the company running the search engine.”

For the comparison-shopping services that have spent the better part of a decade in litigation, the ruling changes the arithmetic more than the argument.

The EU’s wider campaign to prise open Google’s search and Android businesses grinds on along its own track, while the damages claims now have a newer, sharper document to point at and Google has a longer line of claimants waiting their turn.

Whether the courts agree that a DMA finding can carry a competition-law claim will be tested first in London, and the answer there is likely to shape how far the rest of the queue can go.
