Big Tech's AI Investment Boom Rivals 19th Century Railway Mania
The investment in artificial intelligence (AI) across Big Tech companies has reached unprecedented levels, rivaling the UK's railway mania of the 1840s. According to Ameriprise Financial, Amazon.com Inc (NASDAQ:AMZN), Microsoft Corp (NASDAQ:MSFT), Meta Platforms Inc (NASDAQ:META), Alphabet Inc (NASDAQ:GOOGL)(NASDAQ:GOOG) and Oracle Corp (NYSE:ORCL) are expected to invest a total of $729 billion on AI in 2026, increasing to $1.1 trillion by 2027.
Ameriprise Financial notes that this investment boom is not only significant but also comparable to the UK's railway mania of the 1840s, where the spending wave was even larger when measured against the size of the economy.
The comparison raises concerns about what happens when investment in transformative technology races ahead of returns generated by that investment. Historically, technological booms have tended to peak after three to five years and can end abruptly.
Ameriprise Financial cautions that AI needs to show significant returns on investment to justify the massive spending. With hyperscaler investment approaching 50% of revenue and combined free cash flow expected to fall from $200 billion in 2025 to negative $40 billion this year, investors are left wondering whether AI spending will produce measurable revenue, profits, free cash flow, and productivity gains.
