A 6.6% slide to $14.24 takes roughly $1.4 billion off a $20.6 billion market cap in a single session. Moves this size leave the EV maker's valuation resting on whether the $14 area holds into the close.

Rivian sold off sharply from the open and spent most of the day consolidating in the mid-$14s, unable to recover meaningfully.

The move erases roughly $1.4 billion in market value, and for a company that has not yet reached profitability, that kind of single-session compression shifts the valuation conversation quickly.

The $14 area is now the level investors are focused on, tested at the session low and functioning as de facto support.

A 6.6% single-day loss in regular trading leaves the stock at a price where the next move carries real weight for anyone holding or considering a position.
