What are today's top business/market headlines?

I'll browse a couple of top news pages for more details on the main stories.Today's top business and market headlines (October 26, 2026) center on the AI boom, major fundraising, U.S. stock gains, and fallout from Brazil’s election. Here’s a summary of the leading stories:[1]

AI and Tech Fundraising Dominate

•Anthropic files for a potentially record-breaking IPO: The Claude AI maker publicly filed its S-1 with the SEC, planning to list on Nasdaq under ticker “ANT” (possibly as soon as the week of November 16). It reported explosive H1 2026 revenue of about $16.3 billion (up massively year-over-year, with Q2 showing strong growth and a first operating profit on an adjusted basis), but a net loss of roughly $80.7 billion—largely from accounting charges on convertible notes tied to its rising valuation. The filing highlights huge compute costs/commitments (tens to hundreds of billions with partners like SpaceX, Microsoft, Google, Amazon), AI safety risks (e.g., potential self-preserving or manipulative behaviors), and founder control via special share classes. Reports suggest it could raise up to ~$100 billion at a $1.5–2 trillion valuation (up from ~$965 billion privately). This is seen as a major test for AI sector valuations. Chip stocks like Nvidia rose on the news.[2]

•Meta plans massive $95 billion equity raise for AI expansion: Meta outlined plans to raise ~$35 billion via stock sales now, with potential for another ~$60 billion later through a new share class, to fund AI infrastructure. Shares were volatile on the news.[1]

•Related: Goldman Sachs was involved in a big day of AI-related deals (~$210 billion mentioned in coverage); Microsoft is offering voluntary buyouts to as many as ~60,000 employees amid AI-era restructuring; other AI/infra activity includes deals and capacity builds.[3]

U.S. and Global Markets

•U.S. stocks climb, recovering recent losses: The S&P 500 rose ~0.7% (to around 7,677), Nasdaq Composite ~0.8% (to ~26,169), and Dow Jones ~0.3% (to ~52,362). Gains were led by tech/AI and semiconductors (e.g., Nvidia up ~2–2.5%; Philadelphia Semiconductor Index strong). Tesla jumped over 5% on a Barclays upgrade. The rally was fueled by Anthropic IPO optimism ahead of a busy week of mega-cap tech earnings (Microsoft, Alphabet, Amazon) and the Fed’s rate decision (expected to hold steady). Oil prices eased somewhat from recent highs amid Middle East developments.[4]

•Brazilian markets tumble on Lula reelection: Stocks crashed (Ibovespa sharp declines, some names down sharply) after President Luiz Inácio Lula da Silva’s surprise win, with investor fears over higher spending, fiscal risks, and debt. Related Brazilian assets and companies were hit.[3]

Other Notable Deals and News

•EQT to buy Range Resources in ~$13 billion all-stock deal, creating a top U.S. natural gas producer amid LNG and power demand.[1]

•Verizon raises forecasts and signs >$2 billion AI infrastructure deal with AWS.[1]

•HSBC cut global equities to “neutral” citing Middle East tensions and AI regulation risks.[1]

•Additional items: Whirlpool cut outlook (shares dropped); JetBlue reassured on profitability path (shares rose); various earnings and sector moves; ongoing focus on oil/Middle East, inflation/data, and midterms-related policy risks. UK shop price inflation noted as elevated.[5]

Broader context: Markets are focused on whether heavy AI spending will translate into sustained profits/growth (Anthropic’s filing is a key litmus test), the Fed path amid inflation concerns, geopolitical risks (Middle East, elections), and a heavy corporate earnings calendar. AI financing fever remains intense, with massive capital raises and infrastructure commitments.[6]
