How does Polygon handle ticker changes and acquisitions?

Feb 14, 2022
Updated: Jan 18, 2023

Our market data is point-in-time, meaning the data is returned as it happened on a specific date. We do not change the data or concatenate ticker changes into a single aggregate series.
We have a Ticker Events endpoint that will provide information about the full history of a company or ticker symbol, including changes to the ticker symbol, delistings, mergers, acquisitions, etc.
