Software got dramatically more expensive between early 2023 and late 2024, then the rally abruptly stalled. The Software Publisher Price Index jumped from 88.4 in January 2023 to 101.4 in November 2024—a 17-point surge that translated into thousands of dollars in extra annual costs for companies running standard software stacks. But that's yesterday's story. What matters now is what happened next: prices peaked in October 2025 at 102.9, then dropped to 97.7 by August 2026—a 5-point decline that erased nearly a third of the prior gains. If you're budgeting for software in 2026, you're navigating a market that looks fundamentally different from the one that existed just 18 months ago.

The Software Publisher Price Index climbed steadily from 88.4 in January 2023 to a peak of 102.9 in October 2025, then declined to 97.7 by August 2026—a 5.2-point drop that erased nearly a third of the prior gains.
