Last week, four significant Las Vegas Strip resort owners requested a US court to dismiss a claim that they engaged in price-fixing. Caesars Entertainment, MGM Resorts International, Wynn Resorts Holdings, and Treasure Island are accused in the class action complaint launched in January of illegally sharing data with one another through revenue management software in order to artificially inflate the costs of their hotel rooms. 26 of the 33 resorts on or near the Strip are under the collective authority of the four casino companies. 90% of Strip hotels are employed by Rainmaker, which is blamed in the case. In order to increase resort profits, it is asserted that Rainmaker's proprietary software, Guestrev, analyzes real-time pricing and room availability information.
