Some 831,000 Rivian options contracts traded on Monday, or two times its average daily volume.
Much of the options trading has consisted of investors buying "super short-dated calls," said Daniel Kirsch, head of options at Piper Sandler, adding that the options activity had helped drive Rivian's shares higher.
Large purchases of out-of-the-money call options - contracts that are not profitable but stand to gain in value as the stock climbs - can sometimes give an additional lift to a stock's price.
The phenomenon has occurred with shares of various companies popular with options buyers over the last few years, from AMC to Tesla.
Options on another EV name, Nio Inc , were also actively traded on Monday, making it the 10th most heavily traded individual company in the options market.
