The market is riding high on an AI spending boom — but what could crack this rally?
the s&p 500 is up roughly 10% year-to-date, driven by a concentrated ai spending boom. q1 earnings have been strong, but the rally's foundation is narrower than it looks.
upward revisions to 2026 earnings forecasts have been highly concentrated in just a handful of companies tied to ai infrastructure. the rest of the market hasn't seen the same upgrade cycle. that means if those few names stumble — on capex returns, regulatory pushback, or demand slowing — there's not much underneath to catch the fall.
