Big Tech’s $700 Billion AI Frenzy: Gary Marcus Calls It History’s Worst Cash Burn
Written by John Marshall

Amazon, Alphabet, Meta, and Microsoft just laid bare their 2026 spending plans. Combined capital expenditures now top $700 billion, mostly funneled into AI data centers, chips, and servers. Microsoft eyes $190 billion. Alphabet between $180 billion and $190 billion. Meta $125 billion to $145 billion. Amazon holds at $200 billion. That’s up from earlier $650 billion estimates after recent earnings tweaks. MarketWatch tallied the surge following Wednesday’s reports.

Gary Marcus didn’t hold back. The AI researcher and critic labeled it the “greatest capital misallocation in history.” On X, he wrote that these hyperscalers “collectively are spending more money than the Manhattan Project every single month, more than 12x the Manhattan Project every year.” None are booking major AI profits yet. No technical moats protect them. A price war looms large. Customers? Few see big returns on their own AI bets. Business Insider captured his takedown.

Markets split the difference. Alphabet shares jumped nearly 7% after hours on strong cloud growth—$20 billion in quarterly revenue, up 63% year-over-year, with a $462 billion backlog. Google Cloud now hums with AI demand. Microsoft guided to over $40 billion in Q4 capex alone, Azure up about 40%, constrained by capacity. Amazon’s free cash flow cratered 95% to $1.2 billion in Q1 amid $44.2 billion spending, yet AWS backlog hits $364 billion. Meta? Shares tanked 6% to 10%. No cloud business to offset the outlay. Zuckerberg insists billions must flow to chase superintelligence. Yahoo Finance pegged the quartet’s total at $725 billion.

But. Cash piles dwindle. Debt rises. Amazon burns reserves fast. Microsoft offers early retirement to 7% of U.S. staff. Meta plans 10% cuts—8,000 jobs—shifting dollars from people to compute. “If we’re investing more in one area to serve our community, then that means we do need to take down the size of the company somewhat,” Zuckerberg said. Layoffs fund the frenzy. The New York Times detailed the belt-tightening.

Returns? Murky. Alphabet shows payoff—cloud acceleration, Gemini traction. Microsoft ties $25 billion extra to component hikes. Meta lacks a clear monetization path beyond ads. Investors press CEOs: When does the payoff hit? JPMorgan downgraded Meta to neutral, citing capex risks. Bears whisper of fatigue. OpenAI missed revenue targets last year, per Wall Street Journal—though specifics stay guarded here.

Scale staggers. $700 billion rivals small nations’ GDPs. Monthly outspends WWII’s atomic bomb push. Hyperscalers tap cash flows from ads, cloud—profitable cores. Yet AI itself? Break-even distant. Marcus warned earlier: Tech got sold a “bill of goods.” Stocks like OpenAI’s proxies will fall further. Rockets won’t reach orbit.

Power shortages loom next. Grid connections lag three years. Transformers scarce. Natural gas fills gaps. Energy, not chips, bottlenecks buildout. S&P flags oil spikes as risks. Bloomberg charts the ramp.

Wall Street rewards spenders—mostly. But cracks show. Meta’s plunge. Broader tech tumbled on OpenAI news. Marcus’s voice grows louder amid the din. Hyperscalers bet on AI’s tide lifting all. History favors the bold, sure. Bold cash torches too.

Zuckerberg doubled down: Billions necessary. Nadella blames pricing. Jassy points to demand. Ashkenazi touts backlogs. Executives preach patience. Investors? They crave proof. Q2 looms. Capex climbs. Profits? We’ll see.

And if Marcus is right? Greatest misallocation ever. A trillion-dollar what-if. Tech’s poker hand—aces or bluffs?
