Alphabet shares plunged on Thursday and its five-year CDS jumped as much as 5.3bps to 84bps — the largest move since Sept. 21 — after a disappointing earnings print intensified concern that heavy, debt-funded AI investment may not deliver expected returns.

Barclays credit-strategy analysis of trade-archive data found year-to-date CDS trading linked to the top-10 hyperscalers and chipmakers has surged more than eightfold to $176bn. Some swaps, such as SpaceX-linked contracts, have only begun trading in recent months; Oracle CDS is the most active. Related 2026 trading volume is up nearly fivefold YoY to $46.8bn.
