AI and energy IPOs surge as capex cycle accelerates

A fresh wave of IPOs in AI semiconductors and geothermal energy is underscoring investor conviction in the durability of artificial intelligence capex and energy transition trends. Cerebras Systems, a pure-play AI chipmaker, is guiding its IPOInitial Public Offering - a company's first public sale of stock. pricing above the marketed range. Geothermal developer Fervo Energy raised $1.89 billion in a US IPO that priced above range after upsizing the deal. The reception suggests that, despite recent volatility in mega-cap tech stocks, capital markets remain open to focused players in the AI supply chain and clean energy.

Cerebras' strong demand reflects belief that AI inference and edge computing capex are just beginning their ascent. Data center operators are moving workloads closer to end-users to reduce latency and cost, creating new demand for specialized chips beyond NVIDIA's training GPUs. Fervo's success underscores the energy supply crunch and investor hunger for alternatives to fossil fuels, particularly as geopolitical tensions make traditional oil supplies volatile. The Iran conflict has made energy scarcity a multi-year macro theme, benefiting capital-intensive renewable and nuclear plays.

These IPOs sit in contrast to weaker debuts and demand in other sectors. US LBM, a building-materials distributor, reported collapsing earnings. Real estate is under pressure from higher rates and political uncertainty. Consumer discretionary faces headwinds from sticky inflationThe rate at which prices rise across an economy.. The divergence mirrors the broader market: capital is flowing to secular growth themes (AI, clean energy) while value and cyclicals languish.

The risk is that IPOInitial Public Offering - a company's first public sale of stock. enthusiasm masks deteriorating fundamentals downstream. If AI capex growth slows, Cerebras' valuation could compress hard. If geothermal projects face regulatory delays or cost overruns, Fervo could disappoint. Rising rates also make capital-intensive IPOs riskier; if the Fed stays higher for longer, funding costs for scaled-up production will pressure margins. Investors are betting that capex and energy transition trends are unstoppable; a macro slowdown or capex retrenchment would prove that thesis wrong.
