The global software sector lost $830B+ in six trading sessions. The fear is real. The narrative is incomplete. Here is the full picture — and why disciplined vertical investors are positioned to win.
The iShares Expanded Tech-Software Sector ETF (IGV) plunged 30% from its September 2025 peak, erasing over $830 billion in market capitalization in just six trading sessions. Jefferies coined the term "SaaSpocalypse" to describe the carnage.
Our central finding: AI disruption fears account for approximately 60–70% of the selloff's severity. However, AI gave the market "permission to finally re-rate what the numbers had been screaming for three years" — persistent growth deceleration, valuation compression, and deteriorating profitability metrics.
The critical distinction: the SaaSpocalypse is overwhelmingly hitting horizontal, general-purpose SaaS. Vertical SaaS with deep domain expertise, regulatory moats, and embedded workflows is structurally insulated — and positioned to benefit.
What began as quiet multiple compression accelerated into the most aggressive repricing of the SaaS business model in two decades.
Every major SaaS drawdown in the past two decades has fully recovered. The current rout follows a familiar pattern.
"This notion that the software industry is in decline and being replaced by AI is the most illogical thing in the world and time will prove itself."
The SaaSpocalypse narrative is incomplete. The data tells a more nuanced story — one that favors disciplined, vertical-focused investors.
The damage is concentrated in horizontal, general-purpose SaaS. Vertical SaaS is growing ~32% annually versus ~12% for horizontal — 2–3× faster. Deep domain logic and regulatory moats make verticals far more defensible against "vibe coding" threats.
Public SaaS growth rates declined every quarter since 2021. Median growth fell from 30% to 15%. AI gave the market permission to re-rate what numbers had been signaling for years. This is a correction of excess, not the end of software.
The 10-year Treasury went from 1.5% to 4.5%, re-rating all long-duration assets. Paying 9× revenue at 4.5% reflects stronger conviction than 10× at 1.5%. The denominator changed — not just the numerator.
Domain expertise, regulatory moats, workflow depth, and value-based pricing create structural insulation that generic AI cannot breach.
AI is being absorbed into SaaS, not replacing it. 1,971 AI-SaaS deals in 2025 — nearly 2× 2024 and accelerating. 100% of surveyed SaaS companies are increasing AI investment.
As capital retreats from software broadly, competition for quality vertical deals declines. Less competition means better entry terms for disciplined buyers.
AI lowers barriers to build v1, but v1 is 2% of the work. Compliance, integrations, data migration, and enterprise reliability remain hard.
Portfolio companies embedding agentic features become AI-native cooperators, not casualties. AI deepens workflow dependency and increases ARPU.
AI-driven efficiency gains compress R&D, improve margins, and improve Rule of 40. 85%+ of our TVPI is in profitable companies.
AI disruption is real — but it ignited a fire in a forest that had been drying out for three years.
