Shares of electric air taxi maker Archer Aviation Inc ( ACHR ) are surging Monday afternoon, becoming a top trending stock on social media as investors speculated about a potential connection to a highly anticipated announcement from Tesla Inc ( TSLA ) . Here’s what investors need to know.

What To Know: The frenzy ignited after Archer released a promotional video last week featuring its Midnight air taxi alongside a Tesla vehicle and its Optimus robot. The rumors intensified when Tesla’s social media account posted a cryptic video of its logo on a spinning propeller-like object, teasing an announcement for Tuesday.

This led to widespread speculation on social media that Tesla could be entering the electric vertical takeoff and landing market or forming a partnership with Archer.

While many on Wall Street anticipate Tesla’s announcement will actually be the launch of a more affordable EV model, the buzz around a possible collaboration was enough to send Archer’s stock to its highest point since July.

Benzinga Edge Rankings: The stock’s strong performance is underscored by a Benzinga Edge momentum score of 96.55.

ACHR Price Action: Archer Aviation ( ACHR ) shares were up 17.89% at $13.64 at market close on Monday, according to Benzinga Pro.

ACHR is experiencing strong upward momentum, significantly surpassing its 50-day moving average of $9.53. The stock is approaching its 52-week high of $13.92, indicating potential resistance at this level while the recent price action suggests a bullish trend.
