The company originated as a holding company for Buick established on September 16, 1908, by William C. Durant, the largest seller of horse-drawn vehicles at the time. The first half of the 20th century saw the company grow into an automotive behemoth through acquisitions; going into the second half, the company pursued innovation and new offerings to consumers as well as collaborations with NASA to develop electric vehicles. The current entity was established in 2009 after the General Motors Chapter 11 reorganization.

As of 2024, General Motors ranks 25th by total revenue out of all American companies on the Fortune 500 and 50th on the Fortune Global 500. In 2023, the company was ranked 70th in the Forbes Global 2000. In 2021, GM announced its intent to end production of vehicles using internal combustion engines by 2035, as part of its plan to achieve carbon neutrality by 2040. These plans were mostly scaled back in 2025.
