Gartner warns $3.5 trillion in AI spending at risk by 2030

Gartner reported that $3.5 trillion in AI infrastructure spending could face impairment by 2030. Hyperscalers plan to spend about $1 trillion this year and $6 trillion more through 2030, but revenue will fall far short. More than 80% of neocloud providers are expected to cease operations by 2030. CoreWeave shares fell 15.5% as concerns about AI debt grew, and Elon Musk responded with 'yikes' on social media.

CoreWeave stock crashes as analyst warns it could go to zero

CoreWeave shares plunged over 6% in premarket trading after falling 15.5% the previous day. D.A. Davidson analyst Gil Luria warned the company could be the first casualty of an AI downturn and said its equity value could reach zero. CoreWeave's unsecured bonds due in 2032 fell below 80 cents on the dollar. The company carries about $50 billion in debt and lost $626 million last quarter. Retail traders on Stocktwits shifted sentiment to bullish despite the risks.

CoreWeave's struggles highlight debt risks behind AI boom

CoreWeave shares and bonds tumbled again despite CEO assurances about its deal backlog. The loss-making AI cloud company carries roughly $50 billion in debt and has become a symbol of concerns that the data center boom is fueled by borrowed money. The yield on its bonds due 2031 surged past 16%, and the cost of insuring its debt against default implied nearly a 63% chance of default within five years. Gartner said about 80% of neoclouds could shut down by 2030 amid unsustainable AI spending.

CoreWeave bond crash raises alarms across junk bond market

CoreWeave's corporate bonds and shares fell sharply, raising concerns about stress in the high-yield bond market tied to AI spending. The $2.75 billion in 9.75% bonds issued in April traded at 81 cents on the dollar, yielding over 15%. Experts say CoreWeave is a bellwether for AI sentiment and may have borrowed too much too fast. The cost of protecting its debt against default rose to about 881 basis points. Meanwhile, the Federal Reserve may raise interest rates further by year's end, adding pressure on heavily indebted AI companies.

Lumentum stock turns $1,000 into $22,715 thanks to AI demand

Lumentum, once a forgotten laser supplier, saw a $1,000 investment grow to $22,715 over ten years, a 2,171% return. AI hyperscalers replaced Apple Face ID as its main growth driver, pushing fourth-quarter revenue up 109% year over year to $1.01 billion. Most of the gains came in the last 12 months, though the stock dropped 19% in a single week during an optical sector selloff. Management guided first-quarter revenue to $1.225 billion to $1.275 billion and expects strong demand for optical products.

Meta stock jumps 12% after Muse Wonder AI launch

Meta released its first frontier AI model called Muse Wonder on October 13. CEO Mark Zuckerberg pledged to keep spending on AI at scale.

Copper prices hit record high driven by AI data center demand

COMEX copper hit a record $6.95 a pound on September 22 as AI data centers drove new demand. JPMorgan estimates AI infrastructure will add 110,000 tonnes of copper demand by year end. LME inventories fell for 42 straight sessions. A single gigawatt AI campus can use up to 50,000 tonnes of copper. Supply shortages and tariff fears added to price volatility.

AI-spoofed traffic bypasses security at most financial firms

Wipro beats sales estimates on AI growth and European demand

Stock rose 2.4% after the earnings announcement.

Cloudflare and OpenAI expand AI content discovery

Cloudflare and OpenAI shared results from a joint pilot to help AI systems discover more web content. Using about 1% of Cloudflare's network, OpenAI indexed hundreds of millions of new pages for ChatGPT. The collaboration helps AI find specific useful pages that few other sites link to. They are also testing ways to flag harmful pages and improve discovery safety for website owners.

Treat AI Like a New Hire Before Turning It On

Anthropic launched Claude for Financial Advisors, connecting to platforms like Schwab and Orion. Triad Partners experts Shannon McGinnis and Quin Kilgore warn that having a tool available does not mean a firm is ready to use it. Advisors should build compliance programs with vendor checks, use policies, training and ongoing supervision. They also stress that audit logging requires the Claude Enterprise tier, not the Teams plan. Firms without an AI acceptable use policy risk putting their business in danger.

Dollar Index Loses CPI Gain as AI Stocks Slide
