Abstract: In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). The innermost part of the ITk will consist of a pixel detector, with an active area of about 13 m2. To deal with the changing requirements in terms of radiation hardness, power dissipation and production yield, several silicon sensor technologies equipped with novel ASICs connected by bump-bonding technique will be employed in the five barrel and endcap layers. As a timeline, it is facing to production of components, sensor, building modules, mechanical structures and services. This contribution presents the status of the ITk-pixel project focusing on the biggest challenges towards its production and operation, and it summarizes the latest results on developing closest-to-real demonstrator prototypes
