03:50 PM EDT, 10/30/2025 (MT Newswires) -- Maplebear ( CART ) , better known as Instacart, may lose market share as Uber Technologies ( UBER ) deepens its presence in grocery delivery through an expanded partnership with Kroger ( KR ) , Wedbush Securities said in a note Thursday.

Uber ( UBER ) will broaden its collaboration with Kroger ( KR ) in early 2026, enabling users to shop from nearly 2,700 Kroger ( KR )-owned stores via the Uber Eats app, the brokerage said.

Kroger's ( KR ) app will also feature Uber Eats' restaurant listings, creating deeper integration between the two platforms. The companies plan to offer reciprocal trials of their membership programs, Uber One and Kroger Boost, and expand joint efforts in retail media, according to the note.

Wedbush said the extended partnership directly challenges Instacart's position among intermediaries. The firm estimated that Kroger ( KR ) accounts for more than 10% of Instacart's gross transaction value and that the grocer's deeper alignment with Uber ( UBER ) could signal a shift in preferred delivery partners.

DoorDash ( DASH ) also expanded its delivery and retail media offerings with Kroger ( KR ) in late September, underscoring the competitive pressure facing Instacart, the brokerage added.

Instacart's grocery delivery share among intermediaries fell to about 58% in 2024 from roughly 70% in 2022, while DoorDash ( DASH ) and Uber ( UBER ) gained about 300 and 130 basis points, respectively.

Wedbush maintained an underperform rating for Instacart, with a $40 price target.

Shares of the company were down nearly 4% in recent trading.
