Platts is a provider of energy and metals information and a source of benchmark price assessments in the physical energy markets. Platts was founded in Cleveland, Ohio in 1909 by Warren C. Platt (1883-1963) to provide "reliable market-based price information" on the oil industry.
In 2000 McGraw-Hill merged Platts with other like assets to turn the company into a provider of energy information. It is part of the Information and Media Services group of McGraw-Hill. Ever since 2013, the company has held an annual Platts Global Metals Awards, modeled on the Platts Global Energy Awards. In 2015, these were held in London.
