TheMarker (Hebrew: דה-מרקר‎) is the name of three different Hebrew language offerings from Haaretz Media Group:

TheMarker website opened to the public on May 1, 2000 offering ongoing coverage of the capital markets in Israel and globally, high-tech, advertising and media industries, real estate, labor market, consumer markets, the Israeli legal world, communication, vehicles and transportation. The new site ended the monopoly of Globes on economic sites in Israel.

The founder of TheMarker is Guy Rolnik. He was joined by Eytan Avriel, who still serves as the editor of the Internet website and Ido Pollak who was appointed in 2009 as the Director General of TheMarker. Rolnik, Avriel and Pollack established TheMarker in 1999, when the "Haaretz" Media Group was the first investor, followed by the U.S. economy website TheStreet.com as a second investor and partner - a collaboration that has developed due to the economic prosperity and the boom in the high-tech sector and the Internet in Israel and abroad. To build the website about 30 journalists were recruited to create a new independent news reporting system, to serve the site exclusively, and to operate independently from the business section of Haaretz, while emphasizing the capabilities of the Internet to provide continuous news updates and the ability of the World Wide Web to supply economic data. Later an English edition of the site was developed and incorporated into TheStreet.
