Borsa Italiana S.p.A., based in Milan, is Italy's only stock exchange. It manages and organises domestic market, regulating procedures for admission and listing of companies and intermediaries and supervising disclosures for listed companies.
Following exchange privatisation in 1997, the Company was established and became effective since 2 January 1998. It is now a subsidiary of the London Stock Exchange Group plc since 23 June 2007.
Borsa Italiana is also informally known as Piazza Affari ("Business Square"), after the city square of Milan where its headquarters (the Palazzo Mezzanotte building) is located.
The Borsa di commercio di Milano (Milan Stock Exchange) was established by Eugène de Beauharnais, viceroy of the Napoleonic Kingdom of Italy, through decrees dated 16 January and 6 February 1808. It operated under public ownership until 1998, when it was privatized. In Italy until 1997 operated also other smaller stocks exchanges based in several cities of Italy such as Turin, Trieste, Venice, Genoa, Florence, Bologna, Rome, Naples, and Palermo. In 1991 the electronic exchanges were approved and in 1994 the market with grida (A,B,C) was abolished. In Milan were also the currencies exchange rates fixing and the commodities fixing. 
On 1 October 2007, Borsa Italiana was merged with the London Stock Exchange in an all-share takeover, thus becoming part of the London Stock Exchange Group. In March 2016, the London Stock Exchange Group announced the agreement to merge in an all-stock deal with Deutsche Borse, but was subsequently blocked by the EU Competition Regulator.
Borsa Italiana acts as a market management firm operating with autonomy and flexibility. It organises and manages the domestic stock market along with Italian and international brokers through fully electronic trading system. Among its leading tasks, Borsa Italiana supervises listed companies, defining rules for admission and listings and supervising transaction activities.
