What are today's top business/market headlines?
Here's a roundup of today's top business and market headlines (October 17, 2026):
AI/Tech Selloff Dominates Markets
Markets are set for another choppy session after a volatile week driven by AI bubble fears. The stock market is set for a mixed open on October 17 after a volatile Thursday, with the Nasdaq falling as much as 1.4% before recovering to close slightly higher. Chip stocks via the iShares Semiconductor ETF could be headed for a ninth straight loss.
Anthropic IPO Valuation Slashed
In a notable development, Anthropic's expected IPO valuation dropped to $1.5 trillion from $2 trillion, with some investors now expecting a valuation closer to $1.5 trillion over concerns about slowing revenue growth, though the share sale is reportedly still planned for November.
CoreWeave Continues to Slide
CoreWeave fell 15.5% on Wednesday and is down more than 5% premarket today. Nvidia's CEO has tried to calm nerves — shares appeared headed for another steep decline before Nvidia CEO Jensen Huang dismissed concerns about CoreWeave's cost of capital, as Nvidia holds a large stake in CoreWeave.
Other Notable Stock Moves
Broader Market Snapshot
As of Friday's close, U.S. equity markets were modestly lower as the technology sector extended its recent underperformance, while bond yields declined, with the 10-year Treasury yield near 5.09% on reduced market expectations for a Fed rate hike later this month. Internationally, Asian equities finished higher overnight, and European equities advanced as eurozone CPI inflation held steady at 3.8% in September.
Regulatory/Corporate News
The US Treasury Department announced it was imposing a more than $1.2 billion fine on Bank of America, accusing the bank of violating anti-money laundering and sanctions laws.
Markets remain on edge heading into the weekend as investors weigh AI financing risks against still-strong economic fundamentals elsewhere in the market.
