⚠ Data Is Small and Regulators Watch Its PriceLow threat

Market data is an attractive line, but two things temper it. The first is scale: for an exchange the size of GPW, data revenue is a genuinely useful but still modest contributor, and it would have to grow a great deal to move the needle on the whole group. It improves the quality and steadiness of revenue more than it transforms the growth rate. The second is regulation: exchange market-data pricing has drawn increasing scrutiny from European regulators concerned that exchanges over-charge for information investors cannot do without, and there is ongoing pressure to make data cheaper and more accessible.

So the data opportunity, real as it is, sits between a low ceiling on size and a regulatory cap on price. GPW can grow it by building better products and analytics, but it cannot rely on simply raising prices on a captive audience, because that is precisely what regulators are minded to prevent. It is a solid, high-margin piece of the diversification story — steadier revenue on top of the cyclical toll — rather than a transformational one, and an investor should size it as the useful supplement it is, not a growth engine on its own — a small line inside 551,9m zł of group revenue¹.
