The Clock of the Long Now project has no confirmed completion date as of 2026.
The massive mechanical timepiece, designed to run for 10,000 years inside a Texas mountain, remains under construction with no official timeline announced by the Bezos family or Clock Foundation.
The Clock mechanism has been in development for decades with various phases of construction and testing. No recent public updates from the Bezos family or project leadership indicate accelerated progress toward completion.
Bezos is primarily focused on Blue Origin's space ambitions and upcoming IPO plans. Recent signals show Blue Origin securing oversubscribed outside funding and advancing lunar ambitions, suggesting the billionaire's immediate priorities lie in commercial spaceflight rather than accelerating the Long Now Clock project.
