Launch prices have stopped falling. What that means for the customers who planned for them not to.
The multi year decline in per kilogram launch cost has flattened. Downstream businesses that assumed a continued curve are quietly rebuilding their models.

Evidence: Analysis
Per kilogram launch cost to low Earth orbit, on the dominant commercial vehicle, has been broadly flat for eighteen months. The prior decade's decline was one of the most reliable curves in the modern space economy, and its plateau is now a planning assumption for every serious downstream business.
The immediate effect is on the constellations planning refresh cycles into the late 2020s. Business cases built on continued cost decline are being rebuilt around a flat or mildly declining baseline.
The second effect is on the smallsat rideshare market, where operators had assumed pricing pressure from below. That pressure has not materialised, and the smallsat launchers positioning against it have quietly consolidated.
The third effect is on Starship class economics, which remain the sector's single largest open question. Whether the next step change in cost arrives on the timelines their business cases assume will determine which downstream applications become viable.
