PlusAI’s plans to go public fell through for a second time, with the self-driving truck software developer citing a need for more favorable market conditions. PlusAI announced April 21 that plans to merge with Nasdaq-listed special purpose acquisition company Churchill Capital Corp IX were being dissolved by mutual agreement.
