Doesnt help the wall street journal article is paywalled. I found other sources citing the wall street journal article which confirm that the CFO warned about an avalanche of over supply.
At the August meeting, Huang expressed concern that major cloud providers were exploring alternative chips while Nvidia faced an "avalanche" of commitments to purchase chip wafers and memory.
Those concerns followed a financing initiative involving Huang's son-in-law, Nvidia Vice President Nico Caprez, who helped arrange financial guarantees for cloud providers and data-center developers purchasing Nvidia products.
