Wall Street is keeping a close eye on the financial health of AI companies as debt concerns mount. CoreWeave's struggles with heavy borrowing have become a flashpoint, with analysts questioning whether the AI boom is headed for a bubble. Venture capital funding for AI startups is also under scrutiny, and investors are now examining debt loads and cash flows more carefully than before.
Meta is the first major tech company to report quarterly earnings this cycle, and the results will test Wall Street's patience on AI spending. Analysts expect Meta's capital expenditures to reach $196.3 billion by 2027, with Q3 capex projected to jump 117 percent year over year to $41 billion. CEO Mark Zuckerberg showcased the AI agent Muse at Meta Connect, while the company faces a $25 billion settlement order from a New Mexico judge over consumer protection violations.
Nvidia is reportedly in talks to invest hundreds of millions in Firmus Grid, an Australian AI cloud company that recently scrapped its IPO. The move signals continued support for heavily indebted AI cloud providers, even as private credit markets face questions about sustainability.
On the product side, Perplexity now lets Mac users run AI workflows locally using Qwen 3.6 or PPLX Pro, with cloud model access available when needed. Monzo's coding agent, Agent Chip, handles 10 percent of its pull requests across over 3,000 backend services. Both developments highlight how AI is moving deeper into everyday operations.
Bubble warnings keep escalating. Citi's Dirk Willer says US tech stocks are in a bubble, while Yardeni Research's AI Bubble Meter registered a high reading of 83 out of 100. Citadel founder Ken Griffin also said AI bubbles are almost certainly present. Still, historical data shows only 9 percent of similar cases led to a bear market within two years.
Security concerns are rising as well. China-aligned threat actor Storm-0940 used the agentic AI framework ARTEX to automate attacks on hundreds of organizations, gaining privileged cloud access in under three hours. Separately, Socure found that first-party fraud rates rose 21 percent in six months, with AI deepfake attacks up 8,000 percent year-over-year in 2025.
Amid the uncertainty, Wall Street gained ground after strong profit reports from SpaceX and Capital One. The S&P 500 and Dow each rose 0.2 percent, even as a Federal Reserve report showed slower economic growth and reduced business investment.

China-aligned Storm-0940 uses AI framework ARTEX for supply chain attacks
Storm-0940, a China-state aligned threat actor, used the agentic AI penetration testing framework ARTEX to automate attacks on hundreds of organizations globally. The actor used ARTEX to gain privileged access to cloud infrastructure in less than 3 hours in multiple cases. Storm-0940 was responsible for the ConnectWise supply chain compromise of a multi-tenant application. The AI-accelerated activity included reconnaissance and credential changes through Microsoft Graph but did not result from a compromise of Microsoft systems. Microsoft Defender XDR provides detections and hunting queries for suspicious activity related to this campaign.
Socure analysis reveals spike in AI-driven first-party fraud
Socure's analysis finds first-party fraud has increased significantly in the AI era, with Gen Z males disproportionately represented. Fraudsters use AI to create fake images of damaged items after delivery to demand replacements without returning the original. In the last six months, first-party fraud rates rose 21%, and identity-fraud risk rose about 134% from June 2024 to June 2026. Attacks involving AI deepfakes increased 8,000% year-over-year in 2025. Curiosity and economic hardship were cited as the primary motivations for those using AI to commit fraud.
