Recent OpenAI revenue revisions downward to around $50 billion annualized triggered immediate selloffs in Nvidia, Oracle, and related stocks, amplifying trader focus on bubble risks amid rapid inference price declines. Chinese open-weight models now undercut U.S. frontier labs by roughly 90 percent on token costs, eroding market share and pressuring margins as hyperscalers face trillions in data-center commitments financed partly through off-balance-sheet vehicles and high-yield debt. Warnings from investors like Ray Dalio highlight classic bubble dynamics of concentrated capital, rising rates, and overbuild relative to monetization. Strong contracted backlogs and ongoing model improvements provide counterbalance, but upcoming earnings and any further price or regulatory developments could shift sentiment quickly.
