According to Reuters, the Rivian investment deal would value the US electric pickup truck startup at between $1 billion (£770m) and $2 billion (£1.5bn).
It would give the multinational corporations minority stakes in the Plymouth, Michigan-based company, which was initially founded in 2009 and plans to begin selling its R1T pickup truck in late 2020.
Reports suggest if the negotiations are concluded successfully, a deal could be announced as early as this month.
Last year General Motors unveiled a new electric bike brand to offer ‘revolutionary and flexible’ electrification technologies.
Amazon has declined to comment on the story.
