Instacart, Inc. (Maplebear Inc.) shares surged 14.47% in after-hours trading following the release of its fourth-quarter financial results and first-quarter outlook.

The significant upward movement was driven by the company reporting better-than-expected Q4 2025 performance and issuing strong guidance for the current quarter. Instacart's fourth-quarter gross transaction value (GTV) rose 14% year-over-year to $9.85 billion, surpassing analyst estimates, while revenue also exceeded expectations.

Furthermore, the company forecast Q1 2026 GTV and adjusted EBITDA above market expectations. The positive results and outlook were attributed to strong demand for essentials on its online grocery platform as inflation-conscious consumers seek affordable staples, coupled with robust growth in its advertising business, which saw revenue surpass $1 billion in 2025.
