SaaS Rout 2026: Software Now Trades at a Discount to the S&P 500

The iShares software ETF (IGV) is down more than 21% year-to-date, having fallen roughly 30% from its September 2025 peak. Approximately $2 trillion in software market capitalization has evaporated. And for the first time in the modern era, software now trades at a forward P/E discount to the S&P 500 — a benchmark inversion that would have seemed impossible three years ago.

How Far Software Has Fallen

SaaStr’s analysis of the 2026 software market tracks the valuation trajectory across three distinct eras:

• 2020–2022 (zero-rate era): Software traded at 84.1x forward P/E — nearly four times the S&P 500 multiple. SaaS was the canonical growth asset.
• 2022–2024 (rate normalization): The multiple compressed to 43.2x as interest rate hikes repriced long-duration assets. Software still commanded roughly double the market multiple.
• January–March 2026: Forward P/E has collapsed to 22.7x — at or below the broader market for the first time in the sector’s history.

The question the market is answering — or attempting to answer — is whether this is a cyclical repricing or a structural break.

The Seat Compression Thesis

The core fear is straightforward: if a single AI agent can do the work of multiple human employees, enterprises stop buying 500 seats and start buying 100. The SaaS business model — particularly the per-seat pricing that drove growth during the 2010s and early 2020s — is directly exposed to any shift in how organizations staff knowledge work.

The paradox is that overall software spending is still growing. Gartner forecasts a 14.7% increase in 2026, to more than $1.4 trillion. But SaaStr’s decomposition of that headline number is the critical data point: roughly nine percentage points of that growth is price increases on existing software, not net new demand. The remaining growth is overwhelmingly concentrated in AI infrastructure and AI tooling — categories that are often replacing, not supplementing, traditional software budgets. Hyperscalers alone are projected to spend more than $470 billion on AI infrastructure in 2026, and a significant portion of that capital is flowing from enterprise software allocations.

Two Readings of the Same Data

The first reading: software is cheap for the first time in a generation, and the market is overreacting to an AI threat that will take longer to materialize than current pricing implies. The underlying demand for software — workflow automation, analytics, collaboration, compliance — does not disappear because AI agents can do some of what those tools did. Enterprise switching costs are real, integration debt is real, and replacement cycles operate on multi-year timelines.

The second reading: the market has correctly identified a structural shift in the relationship between software and labor. If the enterprise value of a SaaS company is ultimately a function of the number of seats it can sell, and AI compresses the denominator of that equation, the repricing is rational and may not be finished.
