Traders buy CoreWeave 'bubble puts' as neocloud stocks plunge
On Wednesday, shares of neocloud companies, which provide GPU-as-a-service for AI, plunged after CoreWeave's debt yields reached new highs. A Financial Times article reported CoreWeave is targeting insurance companies for additional debt financing. Social Capital founder Chamath Palihapitiya raised concerns about a private credit bubble on X with a screengrab of CoreWeave's bonds hitting a 15% yield, to which Elon Musk replied 'yikes'. CoreWeave stock fell 15%, while Nebius Group and Iren fell up to 10%. Options volume surged dramatically, with traders buying nearly 200,000 puts on CoreWeave versus 106,000 calls. One notable trade involved 26,000 Dec. 18 37.5-strike puts purchased for $1.9 million, which would pay off only if CoreWeave falls another 42%. Analysts speculate these 'bubble puts' could be a hedge against correlated AI stocks or a margin play.

CoreWeave shares tumble 16% as bond yields near 15% on AI debt fears
Stocks fell sharply on Wednesday as concerns over AI infrastructure spending and heavy debt weighed on markets. CoreWeave shares plunged 16%, with bond yields on its 2032 notes reaching 14.8% and 2031 yields over 15%; its five-year CDS spread widened above 1,000 basis points. Oracle dropped nearly 7%, Nebius 9%, and the Nasdaq Composite lost 1.4%. Tech investor Chamath Palihapitiya highlighted the soaring yields, prompting Elon Musk's 'yikes' response. JPMorgan projects hyperscaler AI spending will hit $800 billion this year and exceed $1 trillion by 2027. CoreWeave has over $51 billion in debt and reported a loss of nearly $2 billion in the last twelve months, but CEO Mike Intrator cited a $100 billion backlog, including $103 billion in contractual commitments from Microsoft and OpenAI. The stock recovered Thursday, closing up 5.94%. Analysts warn credit concerns could become a 'self-fulfilling prophecy,' spreading to other AI names. In other news, Netflix announced 6% layoffs, Berkshire Hathaway invested $330 million in Bending Spoons, and CPI data showed persistent inflation.
Goldman Sachs upgrades CoreWeave to buy, sees 73% upside
Goldman Sachs upgraded CoreWeave to 'buy' from 'neutral', asserting that the neocloud's recent sell-off was overblown. Analyst Gabriela Borges trimmed the price target to $106 from $139, yet still implying nearly 73% upside from Friday's close. Borges highlighted CoreWeave's strengths in deploying high-performance GPU clusters and potential to build durable moats beyond pure GPU-as-a-service. The company, which has over $51 billion in debt for AI infrastructure, saw its shares fall 25% last week amid credit market concerns. Borges argued that CoreWeave's asset-backed financing (DDTLs) will keep borrowing costs manageable, with blended cost of debt rising only 100-200 basis points. The upgrade aligns with Wall Street consensus, as 31 out of 45 analysts rate the stock a buy or strong buy.
HSBC warns CoreWeave shares to drop over 30%
HSBC has issued a 'reduce' rating on CoreWeave, a cloud infrastructure provider for AI workloads, with a price target of $39, implying a 36% downside from the previous close. The bank cites structural concerns for 'neoclouds', including CoreWeave's high debt load of over $51 billion and weak return on invested capital (8.9% average 2026-30, below its borrowing cost). Credit default swaps have reached distress levels, and the stock has already fallen more than 25% last week and over 21% in the last five days. HSBC also notes moderating revenue from large language models. The call is contrarian, as most analysts (32 of 45) have buy or strong buy ratings, according to LSEG data.
