DoorDash Shares Rise 0.43% in Tuesday Premarket Trading.

DoorDash shares rose 0.43% in premarket trading Tuesday as the company and Instacart held advanced acquisition talks that could value the grocery platform at about $17 billion. An agreement could come as soon as Wednesday, Oct. 28, though the talks could still fall apart. Neither company has announced a definitive agreement or disclosed payment terms. A deal could value Instacart at about $17 billion, roughly 42% above its estimated $12 billion market capitalization before sale reports emerged Friday. That figure is not a confirmed price.
