Pinterest uses the ticker symbol PINS on the New York Stock Exchange.
Pinterest became a publicly traded company in April 2019, when its Class A common stock began trading on the NYSE. The symbol PINS is a compact reference to the platform’s basic content unit, a “Pin,” while also making the company easy to identify in market listings and financial data.
A ticker symbol is not the same thing as a company’s legal name or exchange. Pinterest, Inc. is the corporate entity, the New York Stock Exchange is the trading venue, and PINS is the market symbol used for its listed shares. Pinterest has also issued different share classes, but the familiar public-market symbol remains PINS.
The most likely mix-up is with invented abbreviations such as PNTR or PINR. Those are not Pinterest’s NYSE symbol. The letters also connect naturally to the platform’s terminology: users save ideas as Pins and organize them on boards.
