** Shares of online grocery delivery platform Instacart CART.O down 3.8% at $39.31
** Grocer Kroger KR.N adds nearly 2,700 stores on the Uber Eats, Uber UBER.N and Postmates apps across the nation, as per its previously announced plans
** "The expanded partnership between Kroger and Uber offers some compelling incentives for shoppers that could draw them away from Instacart in the short term," says Emarketer analyst Sky Canaves
** Though Instacart is the dominant player in the U.S. grocery intermediary space, it is losing share to Uber and Doordash, anaylst says
** In 2025, CART was up 3.6%
