Meta’s Muse Just Put Instacart’s Grocery Empire on Notice
Instacart (CART) shares fell 10.88% over the past month, despite beating revenue expectations and growing gross transaction value 14% year over year. Meta (META) launched Muse, an AI agent that can perform transactions, which may impact Instacart's advertising revenue. Instacart's valuation and partnership strategy are key factors to watch, with earnings reports potentially indicating advertising revenue growth deceleration.
