Key Points
- On Wednesday, October 8, 2025, a renewed optimism surrounding AI led to gains in tech stocks, though competition hindered credit scoring companies.
- Advanced Micro Devices (AMD), a manufacturer of AI chips, and Dell, a server producer, both saw their stock prices rise significantly.
- Equifax announced discounted credit scores for consumers, which negatively impacted the stock of rival Fair Isaac.
Shares of AI chip producers climbed further due to significant deals within the artificial intelligence sector. Simultaneously, heightened competition among credit scoring agencies has put pressure on one of the major industry players.
The S&P 500 increased by 0.6%, with the Nasdaq gaining 1.1% to reach a new closing record, thanks to positive movement in tech and recent minutes from the Federal Reserve indicating a possible interest rate cut this year. The Dow, however, remained relatively stable.
Stock for Advanced Micro Devices surged nearly 12% after announcing a partnership with OpenAI, making it the day’s top performer in the S&P 500 and extending its streak of gains. This week, analysts have raised their price targets for AMD, with Jefferies upgrading its rating from “hold” to “buy.”
Dell Technologies experienced a stock increase of 9.1% after the company raised its outlook, driven by strong demand for AI infrastructure. CEO Michael Dell noted that their diverse array of high-tech products is well-suited to meet the computational, storage, and networking demands necessary for large-scale AI deployment.
The enthusiasm for AI has also lifted shares of other companies involved in the field. Nvidia’s stock rose about 2% after CEO Jensen Huang mentioned a notable increase in AI demand during a recent television interview, predicting that this growth would persist.
Equifax (EFX) revealed it would provide VantageScore 4.0 credit scores at discounted rates or for free, shortly after Fair Isaac (FICO) announced it would deliver FICO credit scores directly to companies that supply reports to lenders. This move could decrease reliance on Equifax and similar credit bureaus. Fair Isaac’s stock tumbled nearly 10%, marking the largest decline among S&P 500 stocks on Wednesday, reversing some of the prior week’s gains, while Equifax’s shares inched up by nearly 1%.
Meanwhile, shares of Live Nation (LYV), the parent company of Ticketmaster, fell 3.4% following the announcement of a plan to issue $1.3 billion in convertible debt set to mature in 2031. The live entertainment entity intends to utilize the funds to pay off senior notes due in 2026, address other financial obligations, and cover general corporate expenses.
