AI Capex Boom Eclipses Dotcom Mania, Investors Stay Calm

As U.S. hyperscalers' investment in AI keeps rising, concerns grow that the massive spending may not generate adequate returns. However, experts suggest the current situation differs from the dotcom bubble of the late 1990s.

Investment Scale and Financing

According to Goldman Sachs and Morgan Stanley analysts, AI-related capital expenditure is expected to reach approximately $800 billion this year. Morgan Stanley raised its 2027 AI capex forecast by 17% to a staggering $1.12 trillion. This massive investment is rapidly depleting Big Tech's cash reserves. PIMCO analysts estimate that capex will absorb 94% of hyperscalers' operating cash flows over the next two years.

Comparison with the Dotcom Era

Lotfi Karoui, a managing director at PIMCO, notes that today's 'we can't afford to fall behind' mania is reminiscent of the late 1990s when aggressive competition and large investments led to overcapacity in fiber optic cables. However, key differences exist: back then, many telecom companies were barely profitable or losing money, whereas today's AI titans have strong balance sheets and high profit margins.

Investor Sentiment and Outlook

Equity investors today are more restrained than during the dotcom era. Tech valuations, measured by forward price-to-earnings ratios, are well below the peaks of 2000. Karoui states, 'AI is in the midst of a capex boom with genuine risks: uncertain monetization, potential overbuild, shortening asset lives, and growing reliance on debt. But for now, it is a more disciplined and far more financeable cycle than the late-1990s telecom boom.'
