Wall Street Can’t Stop Arguing About AI (Or Spending on It)

AI is still the hottest (and most divisive) thing on Wall Street in early 2026. The optimists say we’re in the early innings of a trillion‑dollar tech revolution. The pessimists say we’re in Act II of the dot‑com bubble — and popcorn’s running low.

The scoreboard: Gartner expects global AI spending to hit $2.53 trillion in 2026, jumping to $3.33 trillion in 2027. Most of that will go to infrastructure — aka building digital fortresses for future robot overlords.

Nvidia’s Jensen Huang is planning to sell $500 billion worth of GPUs by the end of 2026. AMD’s Lisa Su says the data center market alone could hit $1 trillion by 2030. In short: AI hardware is the new oil, and everyone’s out prospecting.

Gartner analyst John-David Lovelock says demand is so wild that AI chipmakers and server suppliers are sold out for the next two years. “Companies are still sending love letters begging for equipment,” he said — which is maybe the nerdiest romance story ever told.

But not everyone’s swooning. Gartner warns we may be sliding into the “trough of disillusionment” — the phase when hype fades and accountants start asking questions. Cue the cautious CFOs trimming budgets, angel investors ghosting startups, and big fish snapping up smaller ones.

So yeah, AI might be the new gold rush… or the new metaverse. Either way, the money fire’s still burning — and no one’s found the off switch yet.
