New restaurant deal powers huge gains for SoundHound AI stock

SoundHound published a press release today announcing that its AI Smart Ordering service had gone live at Torchy's Tacos. The service has been adopted at all 130 of the company's restaurant locations. SoundHound's conversational AI software has been trained on the Torchy's menu and has the capacity to manage 100% of the restaurant's incoming calls and handle questions about menu items, specials, store hours, and allergen information. In turn, the utilization of the AI software will allow Torchy's staff to focus on food preparation and providing in-store service.

What comes next for SoundHound AI stock?

While today's explosive gains for SoundHound AI stock were spurred by the announcement of the rollout of services at Torchy's Tacos, there's a foundational element that could be playing an even greater role in the share-price gains. SoundHound AI has gained favor as a meme stock, and its share price has frequently been seeing big shifts on little or no relevant news.

Landing a new contract at Torchy's is certainly a bullish development, and increasing adoption highlights the value and potential of SoundHound's software. On the other hand, bridging its conversational AI ordering software to 130 new restaurant locations is not the kind of announcement that would normally be expected to power such explosive share price gains. While the stock could continue rocketing higher on meme-powered momentum, the recent gains raise some significant valuation concerns -- and there's a good chance the stock will be highly volatile in the near term.
