Paradox Interactive is developing the next significant update for Stellaris, version 4.3, called 'Cetus,' expected to be released in the first quarter of 2026, depending on open beta testing results. The update will focus on refining the game's economy and naval mechanics, with updates to the beta build every two weeks. The initial phase of the open beta will target economic updates and ship design modifications, resulting in a 7% improvement in overall performance. Economic adjustments will include changes to empire size modifiers, unemployment rates, base technology costs, ethics modifiers, upkeep costs, living standards, happiness levels, planetary ascension, and automation buildings. The update aims to lower economic levels and control non-linear growth, while some threats remain unchanged. The development team plans to address issues such as game performance reporting, desynchronization tracking, and optimizations for various game elements. Fixes for ethics shifts and faction issues, new job swap options, and a streamlined slavery mechanic are also in progress, along with improvements to memory usage and multiplayer stability. The release timeline will depend on the outcomes of the beta testing.
