Samsung has yet to reveal the size of the stake (BYD shot down rumors that it was 4 percent), so it's not certain just how much of a commitment it's making. Suffice it to say that the company stands to profit if everything goes to plan, though. The electric car market is quickly heating up, and Samsung could ride the bandwagon by supplying BYD with everything from batteries to processors. As it stands, Samsung might not want to sit on the sidelines when its big rival Apple is reportedly designing an EV of its own.
