Jeff Bezos has filed a statement with federal regulators in the US indicating his sale of nearly 12 million shares of Amazon stock worth more than $US2 billion ($3.1 billion).

The Amazon executive chairman notified the US Securities and Exchange Commission (SEC) of the sale of 11,997,698 shares of common stock on February 7 and February 8.

The collective value of the shares of Amazon, which is based in Seattle where he founded the company in a garage about three decades ago, was more than $US2.04 billion ($3.13 billion), according to the listed price totals.

The stocks were grouped in five blocks between 1 million and more than 3.2 million.

In a separate SEC filing, Bezos listed the proposed sale of 50 million Amazon shares around February 7 with an estimated market value of $US8.4 billion ($12.9 billion).

Bezos stepped down as Amazon’s chief executive in 2021 to spend more time on his other projects, including the rocket company, Blue Origin, and his philanthropy.

His address on the stock filings is listed as Seattle, although he reportedly has relocated to Miami.
