Global markets fell on Thursday as AI stocks slid on worries about the cost of borrowing to build data centers, with the S&P 500 down 1.3% and the Nasdaq down 2.4% midday, after sharper losses in Asia. Lam Research fell 11.1% despite slightly stronger-than-expected profit and revenue, as its forecast midpoint for the coming quarter was slightly below analyst estimates. Nvidia dropped 4.3%, CoreWeave 9.6% on debt concerns, and Meta 7.4% despite revenue above expectations. Brent crude rose 2.9% to US$111.99, its highest in five months, amid the war with Iran. The 10-year Treasury yield fell to 4.98% from 5.13% as investors sought safety, though it remains well above its 3.97% level before the war.

Direxion Daily Semiconductor Bull 3X Shares (SOXL) fell over 16% to a six-month low as the Nasdaq slid and QQQ dropped over 2% amid an oil price surge. Brent crude rose 2.3% to over $111 per barrel, and U.S. President Donald Trump blamed Iran, calling the surge a purposeful ploy ahead of the midterm elections. Wells Fargo said Nvidia CEO Jensen Huang's remarks that neoclouds face a scarcity of funding, not customers, spooked markets and revived concerns about credit and risk appetite. NVDA fell 3.8%, while SMH, SOXX and DRAM dropped 4.8%, 5.5% and almost 6%, and CoreWeave (CRWV) and Iren (IREN) hit fresh lows.
- Sinking AI stocks undercut markets worldwide as oil climbs to its highest price since May
The S&P 500 fell 1.3% and the Nasdaq composite was down 2.4% around midday, after sharper losses in Asia, while the Dow slipped only 0.1%. AI-related shares sank on worries about the rising cost of borrowing to build data centers and buy chips, as well as high valuations, with Lam Research down 11.1% despite a slight profit and revenue beat, Meta down 7.4%, Nvidia down 4.3% and CoreWeave down 9.6%. South Korea's Kospi fell 3.5%, and Brent crude rose 2.9% to $111.99 a barrel amid uncertainty over the war with Iran. The 10-year Treasury yield dropped to 4.98% from 5.13%, but remains well above its 3.97% level before the war as investors sought safer assets. Most S&P 500 stocks still rose, and results from Procter & Gamble, Lockheed Martin and CSX helped limit losses.
- AI stocks tumble and drag down markets worldwide as oil prices climb
AI stocks slid on Thursday and dragged markets worldwide lower, while oil prices hit their highest since May on worries about the war with Iran. The S&P 500 fell 1% and the Nasdaq composite 2% as of noon, after sharper losses in Asia, where South Korea's Kospi dropped 3.5%. Nvidia fell 3.7%, Meta lost 5.4% despite stronger-than-expected revenue, and Lam Research tumbled 10% even though its results slightly beat forecasts. Brent crude rose 2.2% to $111.19, and U.S. Treasury yields fell, with the 10-year dropping to 5.00% as investors sought safer assets. Worries about costly AI borrowing and high stock prices remain, while France's CAC 40 fell 1.4% as French bond yields climbed on debt worries.
- Bitcoin circles $81.5K ETF cost basis as Trump Iran comments send stocks lower
Bitcoin extended daily losses to 3% and traded below $82,000 as US stocks fell after President Donald Trump said the US was “not negotiating” with Iran and reiterated the possibility of new military action. BTC/USD hit $81,256 on Bitstamp, down 2.9%, while at the open the S&P 500 fell 1.3% and the Nasdaq Composite lost 2.3%. Treasuries benefited from the risk-off mood, with the US 10-year yield approaching 5% and slipping to its lowest level since Sept. 23. Bitfinex Alpha analysts expect BTC/USD to trade between $81,300 and $84,400 until the Federal Reserve's Oct. 28 meeting, with a close below $81,300 raising the risk of a move toward the Oct. 15 low of $79,821. Kalshi traders have cut the odds of new all-time highs by mid-January 2027 to just 3%.

- Musk's wants to merge SpaceX and Tesla: Here's what to know
Musk said SpaceX and Tesla have formed special committees to study a merger, which would be worth about $3.5 trillion combined and would be the largest corporate deal in history. SpaceX, valued at about $2 trillion after a record listing this year, absorbed Musk's AI startup xAI in February, while Tesla is valued at about $1.5 trillion. Musk holds about 82 percent of SpaceX's voting power but only about 20 percent at Tesla. Dan Ives puts the odds of a deal at 90 percent by early 2027, though Musk called the requirement of a majority of all Tesla shares 'quite a high hurdle'. Loyal retail investors hold an estimated 25 to 27 percent of Tesla shares, and legal obstacles appear slight because both companies moved their incorporation to Texas from Delaware.
- CoreWeave and Nebius Stocks Are Crashing. Time to Buy the Dip?
Shares of Nebius and CoreWeave each fell 25% in the week of October 12 to 16. The sell-off stems from the yield on CoreWeave's debt in the secondary market surging to 15%, versus roughly 5% on Treasuries, which pushes the debt into 'distressed' territory and signals doubts about its ability to meet obligations. Nebius sold off in sympathy as a fellow neocloud company. The bigger concern is that both companies must keep issuing debt to fund data centers, and if yields are high at issuance, the assumption of nearly unlimited cheap capital could be challenged. The author says it is unclear whether now is the time to buy.
- Disney’s multiplatform Super Bowl plan frustrates ABC affiliates
ABC station owners are irritated that Disney is airing the Super Bowl across several platforms, including Disney+, ESPN2, NFL Network and ESPNU, even though the game is already on ABC and ESPN. A station group CEO estimates that the combined platforms could cut broadcast ad revenue by up to 35% compared with last year. Local affiliates typically earn about 3% of annual ad revenue from the Super Bowl and pay network owners reverse retransmission fees, but Disney+ lacks geofenced ad insertion, so affiliates cannot sell ads to streaming viewers. Disney says national commercials will be identical on all platforms and that streaming major live events is standard industry practice. Super Bowl LX drew 125.6 million viewers in February.
- Meta’s deal to keep Zuckerberg in California adds fuel to wealth tax debate ahead of election
Meta says Mark Zuckerberg will remain in California for eight years and has created a new stock plan that could help cover his taxes if Proposition 40, a 5% tax on Californians worth over $1 billion, passes on Election Day on Nov. 3. According to a filing released with its third-quarter earnings, Meta will issue non-voting Class C shares starting in January, and Zuckerberg can sell or transfer up to 20% of the shares granted to him without affecting his majority voting control. The filing says Zuckerberg’s leadership is crucial to the company’s growth and its AI ambitions, including Meta Superintelligence Labs. Most of the tech industry opposes the measure, while a recent Citrin-Politico poll found 46% in favor and 43% against, suggesting it may fall short of the majority support it needs.
- Nasdaq sell-off: A momentum unwind 'for the record books'
Matt Stucky, chief portfolio manager for equities at Northwestern Mutual Wealth Management, calls Thursday’s sell-off in the Nasdaq Composite (^IXIC) a momentum unwind “for the record books.” He says the market spent the first half of 2026 driven by a beta and momentum trade led by semiconductors, but in the third quarter, as rates rose, money shifted into quality stocks. He does not think the sell-off is justified by fundamentals, arguing that institutional portfolio managers swapping out of factor positions can drag down whole baskets of stocks. In semiconductors, spot rental rates for Nvidia Blackwell chips are higher than a month ago, showing tightening compute supply, even as financing costs rise and investors worry about neocloud business models and the rising cost of insuring their bonds.
- Dune launches real-time data feeds covering 200 onchain trading venues
Blockchain analytics platform Dune has launched real-time market data feeds covering more than 200 onchain trading venues, aiming to bring this data into the systems of traditional financial institutions. The feeds draw trade data from 12 blockchains, including Ethereum, Solana and Base, about one second after execution, covering both spot trading on decentralized exchanges and perpetual futures on Hyperliquid and Lighter. Early clients include quant funds, market makers, asset managers and bank trading desks, which use the data to assess liquidity and compare prices, though Dune did not name them. Meanwhile, the tokenized stock market has grown sharply, with distributed value reaching $3.58 billion, but 16 companies, including Microsoft, Alphabet and Goldman Sachs, have objected to their shares being traded on OKXICE’s proposed platform, and liquidity remains fragmented.
