The Belle II experiment currently records data at the SuperKEKB $e^+e^-$ collider, which holds the world luminosity record of $5.2\times10^{34}$ $\textrm{cm}^{-2}$ $\textrm{s}^{-1}$ and plans to push up to $6\times10^{35}$ $\textrm{cm}^{-2}$ $\textrm{s}^{-1}$, after an upgrade of its interaction region. To cope with the increased backgrounds, a new fully pixelated vertex detector (VTX) is...

The electron–positron Future Circular Collider (FCC-ee) is the European particle physics community’s plan A for succeeding the LHC as the world’s premier collider facility. Precise reconstruction of primary and secondary interaction vertices is central to the FCC-ee physics programme, enabling measurements of rare flavour processes and of Higgs and Z boson decays to bottom, charm and strange...

Challenges and solutions are evolving with increasing pile-up and data volumes.
The talk will review the latest developments at CMS, ATLAS and LHCb.
New possibilities are opened by the addition of precision timing.
