Nov. 6, 2026 — A sharp selloff in technology stocks and weakening confidence in artificial intelligence investments are testing the resilience of global financial markets, raising concerns about whether pressure in the AI sector could spread into broader financial markets.
The tech-heavy Nasdaq-100 rose nearly 2% on Friday, recovering part of Thursday’s decline of more than 6%. Despite the rebound, investors remained cautious as volatility increased and several indicators of financial stress began flashing warning signals.
Policymakers have previously warned about the risks of an AI investment boom unraveling. Investors and regulators are now monitoring market volatility, credit risks and funding conditions for signs that the technology sector’s difficulties could trigger wider disruptions.
Market Volatility Rises as Investors Become More Cautious
Wall Street’s main volatility gauge, the Cboe Volatility Index, known as the VIX, climbed above 28 on Thursday, reaching its highest level since late March.
It remained close to that level on Friday and had surged more than 40% during the week.
The increase was significant but remained relatively contained compared with the volatility spikes following the April 2025 “Liberation Day” market turmoil and the August 2024 selloff.
Europe’s equivalent volatility gauge also climbed, reaching its highest level since May on Friday.
Idanna Appio, a portfolio manager at First Eagle Investments, said investors should watch for further increases in volatility and signs of deeper market stress.
“It’s still early days,” Appio said, adding that her concerns would increase if markets experienced additional volatility spikes or problems accessing financing.
AI Debt Risks Become a Major Concern
One of the clearest warning signals has emerged in the market for credit protection against corporate defaults.
The cost of insuring debt issued by AI cloud infrastructure company CoreWeave has surged into distressed territory. Five-year credit default swap spreads climbed above 1,000 basis points, reaching record highs.
Credit default swaps, or CDS, are financial contracts that provide protection against a borrower’s default. Higher spreads generally indicate that investors perceive greater credit risk.
CoreWeave’s rising borrowing-risk indicators have become an important measure of investor anxiety surrounding the AI industry.
Credit default swap spreads for SpaceX and Intel have also increased this week, reflecting broader concerns across technology-related companies.
High-Yield Bond Market Shows Signs of Pressure
The selloff has also affected the wider corporate debt market.
The additional yield investors demand to hold U.S. high-yield corporate bonds, commonly known as junk bonds, has climbed to its highest level since the market turmoil following the April 2025 Liberation Day tariffs.
Risk premiums have increased even more among companies with the weakest credit ratings.
For businesses rated CCC or lower, the premium has reached around its highest level since 2020, according to ICE BofA indexes.
The increase suggests investors are becoming more reluctant to take on riskier corporate debt as uncertainty grows around technology companies and the broader economy.
Investors Move Toward Safer Assets
The market turmoil has encouraged some investors to shift toward traditional safe-haven investments.
U.S. 10-year Treasury yields have fallen approximately 50 basis points from peaks above 5% reached last month.
Those earlier increases reflected concerns about high government debt, rising inflation and competition for capital as technology companies expanded their bond issuance to finance AI infrastructure.
Currency markets have remained relatively stable, although the U.S. dollar has shown signs of attracting additional demand.
The dollar was up 0.6% against a basket of currencies as of 1500 GMT on Friday.
Demand for dollar funding also increased. Three-month euro cross-currency basis swaps briefly reached minus 8 basis points on Thursday, their lowest level since late 2023, signaling a greater premium for obtaining U.S. dollars through currency swaps.
The measure recovered slightly on Friday to around minus 6 basis points.
Meanwhile, Bank of America’s Flow Show report indicated that cash funds received $140 billion in inflows during the week through Wednesday, marking the seventh-largest weekly inflow on record.
Treasury Market Remains Relatively Stable
Despite the growing pressure in technology stocks and corporate credit, government bond markets have not yet shown the kind of severe disruption experienced during the COVID-19 pandemic or the April 2025 tariff-related market turmoil.
The closely watched MOVE index, which measures volatility in the U.S. Treasury market, reached a six-month high in October but has since declined.
That relative stability suggests that, while investors are becoming more cautious, the latest market turmoil has not yet translated into widespread dysfunction in government bond trading.
Investors Watch for Signs of Wider Contagion
The latest AI-related selloff has placed several areas of the financial system under closer scrutiny.
Rising volatility, record-high credit protection costs for CoreWeave, widening high-yield bond premiums and increased demand for cash and dollar funding all point to greater investor caution.
However, the indicators remain mixed. The Nasdaq-100’s Friday rebound and the retreat in Treasury market volatility suggest that stress has not yet reached the levels seen during previous major market disruptions.
For investors, the central concern is whether the correction in AI-related stocks will remain concentrated in technology and infrastructure companies or develop into a broader financial market problem.
