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. In February 2013, Platts entered into a strategic partnership with leading Indian polymer market information provider, PolymerUpdate, to publish unique and critical Joint Reports on polyethylene, polypropylene and polyvinyl chloride for the South Asian countries of India, Nepal, Pakistan, Bangladesh and Sri Lanka.
