AI Bubble Bursts: What's Next for Tech?

The much-discussed AI stock bubble appears to have burst, with valuations for major tech companies significantly decreasing. Since October 2025, the price-to-earnings ratio for information technology and Big Tech has fallen to its lowest point since the pandemic era, mirroring patterns seen during the dot-com bubble, albeit with lower peak ratios.

The tech sector has experienced a notable downturn, partly due to the 'SaaSpocalypse.' This phenomenon describes the rapid selloff of software-as-a-service (SaaS) stocks, driven by investor concerns that agentic AI could easily supplant existing software business models. Companies like Salesforce and ServiceNow have already seen substantial value reductions this year.

Beyond SaaS, the semiconductor industry is also facing a slowdown. Recent geopolitical tensions and supply chain challenges, including tariffs and conflicts, have exacerbated a chip shortage fueled by high demand. This has created a more complex operational environment for tech firms.

An emerging concern is the sustainability of the remarkable earnings growth seen in tech companies. While the Magnificent Seven have shown robust growth, projections suggest this level may not be maintainable. Goldman Sachs estimates significant AI capital expenditures for 2026, with potential headwinds including lower-than-anticipated demand and employee anxieties about job displacement.

Furthermore, a precarious global economic situation poses a greater risk to AI earnings. Ongoing conflicts have disrupted critical supply chains, such as helium output from Qatar, essential for chip manufacturing. Rising energy prices also threaten to increase operating costs for data centers, potentially impacting company revenues even if AI demand remains steady.
