you can get a gauge on Oracle debt by looking at CDS prices ( basically insurance that pays out if Oracle defaults on debt ). The link is from 4 months ago and it feels weird to link to reddit but CDS prices have risen quite a bit which implies loaning Oracle money is feeling riskier than it use to be. I don't know what the prices are now.

I wish i could remember exactly but there was some financing bet or debt structuring thing that Oracle did that didn't go according to plan and put them in a bad spot.
