Broadcom's $63 Billion Anthropic Financing Deal Powers AI Stocks

Broadcom climbed 4% on Tuesday after announcing a $63 billion financing deal in which several Wall Street firms will help Anthropic gain access to Broadcom's XPU AI accelerators and networking solutions. The move made Broadcom one of the strongest forces lifting the S&P 500, which rose 45.83 points, or 0.6%, to 7,722.60 — within 1.2% of its all-time high set earlier this month.

The gain matters beyond one trading session. AI stocks have swerved for weeks on worries that the boom is under threat because companies face expensive borrowing costs to build data centers and buy more AI chips. Tuesday's deal shows a mechanism for bridging that gap: Wall Street financing arranged directly against future AI hardware purchases.

How did the AI complex trade?

The Nasdaq composite climbed 1.2%, adding 308.43 points to close at 26,477.81. The Dow Jones Industrial Average rose 15.99 points, less than 0.1%, to 52,377.57.

Most stocks within the S&P 500 actually fell. Gains in a handful of influential AI names more than covered those losses. Nvidia added 0.9% and, alongside Broadcom, ranked among the strongest forces pushing the index higher. CoreWeave, a company that borrows money to buy AI chips and rents them out over the cloud, jumped 7.9% and held its gains through the day after several sessions of sharp swings.

The pattern is narrow leadership: index gains concentrated in chip and AI infrastructure names while the broader market lags.

What moved outside the AI trade?

General Motors climbed 5.5% after saying it will move its stock listing from the New York Stock Exchange to the Nasdaq. The automaker called the Nasdaq, home to several of the world's biggest technology stocks, a fit for its tech-driven strategy. The switch could also let GM join the Nasdaq 100 index, which would force funds that mimic the index to buy the stock. GM had traded on the NYSE since 1911.

JetBlue Airways flew 19% higher even though it reported a larger summer loss than analysts expected. CEO Joanna Geraghty said the company expects to return to sustained operating profits next year and to deliver at least $1 in earnings per share in 2028. Investors may have been bracing for worse: the stock entered the day down nearly 48% for the year.

Royal Caribbean Group rose 5.5% after posting a stronger summer profit than analysts expected and raising its full-year profit forecast.

The losers told the other side of the profit-pressure story. Boeing fell 10.7% after reporting a larger quarterly loss than analysts expected. Hilton Worldwide sank 2.1% on weaker summer revenue and a fourth-quarter profit forecast whose midpoint sat below expectations; the hotel company said it expects "increased impact from the Middle East" during the quarter.

Sherwin-Williams dropped 2.7% after missing profit expectations. High mortgage rates have chilled the housing industry and, with it, demand for paints and coatings. "Customer sentiment and the leading indicators we track point to muted demand over the remainder of the year and into 2027," CEO Heidi Petz said, while inflation pushes up the company's raw material costs.

What do rates and consumers signal?

Treasury yields held relatively steady a day before the Federal Reserve's latest interest rate decision. The Fed hiked the fed funds rate last month for the first time in three years to slow inflation, but the widespread Wall Street expectation is a hold this time. The 10-year Treasury yield edged down to 4.99% from 5.00% late Monday.

Oil helped keep yields in check. Brent crude fell 1.2% to $109.41 a barrel. Consumer confidence, which has tumbled under inflation pressure, improved in October against economist expectations of further weakening.

Abroad, indexes were mixed across Europe and Asia, with Seoul up 3.1% and Shanghai down 1.3% among the bigger moves.

What comes next?

The commercial question now is whether financing structures like the $63 billion Broadcom-Anthropic arrangement can keep the AI capex cycle funded at current interest rates. With analyst expectations for profit growth already high, further index gains likely depend on whether the AI leaders can keep converting borrowed capital into revenue.
