Oracle cancels order for 300–400 AI training chips from Supermicro, raising doubts about AI infrastructure vendor stability

Oracle (ORCL) canceled a purchase order for 300 to 400 Nvidia GB300 NVL72 AI accelerator chips (specialized processors that train large language models) that were being supplied by Super Micro Computer (SMCI), according to reports citing Bluefin Research.

This cancellation signals potential weakness in Supermicro's ability to retain major customers for AI infrastructure contracts — the high-margin business of supplying the servers and chips that power AI data centers. If other major cloud providers follow Oracle's lead, Supermicro's revenue growth from AI could slow significantly.

For business professionals and investors: AI infrastructure stocks like Supermicro are now riskier bets than previously assumed, since even large orders can be reversed. For companies planning AI deployments, this suggests supplier lock-in is weaker than expected, giving you more negotiating power but also less certainty about long-term component availability.
