The money funding America's AI buildout is increasingly coming from Europe.

Hyperscalers — the big cloud and AI companies behind the AI boom — have raised $48 billion in European-currency bonds so far this year, according to Apollo's Daily Spark note published this week. That is more than triple what they raised in all of 2025. The tally breaks down to €27 billion in euro-denominated bonds, £13 billion in sterling, and CHF 7.5 billion in Swiss francs.

CoreWeave built its reputation selling raw AI compute. Now it wants to sell the software layer on top of it. At its Fully Connected conference, the company unveiled CoreWeave Forge, a development platform that folds model serving, observability, post-training, and evaluation into a single environment — and it comes with a striking performance claim: a preview feature called RL Rollouts that improved model reload latency by 15x in testing.
