The Santiago Stock Exchange (SSE) is the largest exchange in Chile and the third largest stock exchange in Latin America. The SSE was founded on 27 November 1893.

Historically, the SSE has been home primarily to large local companies. However, over the last 10 years, a number of medium size companies and foreign companies have listed on the SSE as well. As of December 2023, there were more than 200 local securities' issuers listed in the SSE and more than US$2 billion of securities are traded in the SSE per day. As of November 2023, the market capitalization of the companies listed on the SSE was approximately US$174 billion.

The SSE does not specialize in or encourage listings by particular types of companies. Companies from all industrial sectors and sizes have been listed on the SSE. However, the SSE has recently prioritized the offering of new financial products, such as ETFs, derivatives, venture, and green and social bonds.

The SSE is a part of the Integrated Latin American Market (MILA), a program that integrates the stock exchange markets of Chile, Colombia, Peru and Mexico. This program is intended to develop the Latin American capital markets through the integration of these four countries, giving investors greater access to different securities, issuers and sources of funding.

In November 2023, the SSE announced the materialization of a process of integration with the Colombian Stock Exchange and the Lima Stock Exchange through a regional holding based in Chile that controls those three exchanges. The integration process aims to create a more liquid and profound market for issuers and investors and its operational aspects, including the negotiation platform, compatibility between compensation and liquidation entities, securities deposits, technological and communications infrastructure generally and internal rules, are expected to be complete by 2025.
