CoreWeave shares drop sharply amid AI debt fears

CoreWeave shares fell 20% in early trading as bond yields rose and debt costs climbed. The company relies on bonds to fund its data center construction. Nvidia CEO Jensen Huang expressed confidence in CoreWeave and rejected any bailout idea. Deutsche Bank called the selloff a buying opportunity. The stock rebounded 5.9% on Thursday but remained under pressure.

Jensen Huang says AI investment worries will pass

Nvidia CEO Jensen Huang said recent AI stock declines are temporary and that AI will positively impact every industry. The Philadelphia Semiconductor Index fell for eight straight days, its longest losing streak since 2008. CoreWeave, Nvidia's second-largest holding, saw its credit default swap premium hit a record high, implying over 60% default risk within five years. CoreWeave has a backlog exceeding $100 billion but total debt of $52 billion. Huang said CoreWeave's cost of capital is actually decreasing.

Investor debt fears hit AI stocks and bonds

Investor concerns about debt levels caused CoreWeave shares to drop 15% on Nasdaq before recovering nearly 6% on Thursday. The company's bond yields rose above 15%, a level considered severely distressed. Gartner analyst Will Sommer warned that multitrillion-dollar AI infrastructure writedowns are likely by 2032 if spending continues. Bell Canada is building an AI data centre in Saskatchewan where CoreWeave and Cerebras will be tenants, with Bell investing $1.7 billion initially. Scotiabank warned that a default by either tenant could delay Bell's return on investment.

Employee AI use creates security risks for companies

NordLayer launched AI Scout, a tool designed to prevent employees from leaking sensitive data through AI chatbots. The platform inspects prompts before submission and can block or redact risky information. It also monitors shadow AI, the unsanctioned AI tools employees use without IT approval. NordLayer cites research showing 70% of workers use free public AI tools on the job. Breaches involving shadow AI cost about $400,000 more than the global average breach cost of $4.99 million.

6 AI security platforms CISOs can evaluate

Tech Insider reviewed six AI workspace security platforms that help organizations control AI tool usage. Pluto Security focuses on endpoint visibility, tracking AI coding tools, agents, and MCP servers that operate under user credentials. Harmonic Security discovers AI tools across the workforce and provides prompt-level visibility across over 1,000 applications. The article highlights growing concerns about unsanctioned AI use, autonomous agents accessing enterprise systems, and the need for inline data controls over prompts and generated content.

The Hartford unites data and AI teams under one tech division

The Hartford is merging its Data and Artificial Intelligence teams into its Technology division starting 2 November. Shekar Pannala will lead the combined unit as CIO. The change puts data, AI and technology under one executive. President A. Morris Tooker said the move will help embed advanced analytics into customer services. The restructuring also places Claims and Operations under chief claims officer Stephen Deane.

UAE leaders plan AI PCs as security becomes essential

The study was run by Vanson Bourne in June 2026 across EMEA.

Schneider Electric raises outlook on data center demand

AI stocks fall but data center construction keeps growing

AI infrastructure stocks sold off this week but data center construction is still expanding. Hut 8 is building a 649-acre AI data center in Louisiana. The site is filled with construction workers and large transformers. Eric Jackson of EMJ Capital toured the facility and said the real-world buildout is thriving. The project shows that data center demand remains strong despite Wall Street concerns.

NBA uses AI to flag suspicious sports bets

The NBA is tightening betting rules for the 2026-2027 season. The league created an AI-based monitoring platform to spot suspicious wagering. The system analyzes basketball data, injury reports and social media. Commissioner Adam Silver wants more access to betting data and control over betting markets. The changes follow gambling cases involving former players Jontay Porter, Terry Rozier and Damon Jones.

Can AI agents reliably improve themselves?

Researchers studied whether automated systems can safely decide if an AI agent's update is a true improvement. They found that in general, no terminating procedure can guarantee both reliability and completeness. However, they showed that bounded evaluation with finite budgets can recover some safety guarantees. The study reveals limits of self-improvement in unbounded settings.
