Yes — this is common.

Exchange processes are often nonlinear and intentionally opaque. Even late in the cycle, confirmation timelines can remain fluid. Internal approvals, slot prioritization, market conditions, and competing listings all influence timing — and exchanges tend to preserve optionality until the final stage.

This dynamic is partly structural and partly strategic. Exchanges maintain leverage by avoiding early commitment, particularly when demand for listing slots is high. Until internal approval is fully secured, dates are rarely definitive.

The key is contingency planning. Projects approaching TGE should maintain parallel paths — liquidity readiness, alternative venue sequencing, and flexible launch timing — rather than anchoring to a single assumed outcome.
