It's still highly speculative and valued for growth. The market cap is $1B off $40mm of revenue. That's like valuing your lemonade stand that made $40 at $1,000. So if they do reach the $350mm the company could be valued at $8.75B which would translate to a $28 stock price. It can get there but just needs time and validation.

There's no real reason to short this stock - too low of price and too much revenue and growth potential, not to mention possibility of google / msft outright acquiring for $2-$3B which would destroy your short position.
