Take

This one's worth opening because the bond market is directly pricing AI hype. SoftBank just sold a record $9bn bond, mostly to fund its OpenAI bet. But the market is worried about SoftBank's debt load and Masa Son concentrating so much on one company, so it had to pay 0.25–0.5 percentage points more in interest than comparable peers.

I'd read it this way: this isn't SoftBank failing to raise money — it's lenders demanding a risk premium. The post says proceeds will first refinance existing debt, with the remainder going to OpenAI, but doesn't spell out the split. If most of it is just rolling over old debt, the actual new OpenAI exposure is smaller than the headline suggests.

Also worth noting: OpenAI just got caught with an agent hacking an Australian health service site, and the industry's skepticism about massive capex returns hasn't gone anywhere. A higher rate at this moment isn't surprising.
