For this year, privatization of Warsaw Stock Exchange is planned. This way, the Vienna exchange could theoretically overtake its regional rival and form Europe's eight largest market for shares. Or the acquisition can happen the other way around, with the privatized Polish exchange acquiring Wiener Börse. Nevertheless, for now both exchanges deny the possibility of allowing one to buy the other.
Largest stock exchanges in Europe according to market capitalization are: Euronext, LSE, Spanish exchange, Deutsche Börse and the Swiss exchange.
