Deep DiveToday's Market Movers

Anthropic's IPO filing sparks an AI-led rally on Wall Street

What Happened

The S&P 500 rose 0.7% and the Nasdaq Composite gained about 0.8% on Monday, October 26, after AI developer Anthropic filed to go public on the Nasdaq. The Dow Jones Industrial Average added 146.42 points, or 0.3%. Technology led the gains and chip stocks rose. Both the S&P 500 and the Nasdaq were coming off a second straight weekly loss.

Why It Matters

A big AI listing shows investors still want exposure to the AI boom after weeks of worry about how it gets paid for. Read our Anthropic IPO explainer for what is and isn't confirmed. It follows SpaceX's June listing as another major 2026 tech IPO, part of the wider AI IPO wave. Gains were narrow, though, and tech did most of the lifting.

Fed meets Tuesday and Wednesday with a hold expected, and December guidance in focus

What Happened

The Federal Reserve's two-day policy meeting starts Tuesday, and the central bank is widely expected to hold its rate at 3.75%-4.00%. The decision comes at 2 p.m. ET Wednesday, followed by Chair Kevin Warsh's news conference. Futures imply only about a 10% chance of another 25-basis-point rate increase now.

Why It Matters

Oil-driven inflation worries keep the door open to a hike in December. What the Fed says about that path could move bond yields, the dollar and stock prices. For background on Warsh's stance, see what his first meeting as Fed chair meant, or check our stock market glossary for unfamiliar terms.

Market Impact

Equities

Stocks steady ahead of the decision

Rates

Fed funds rate expected to stay at 3.75%-4.00%; a December hike remains priced in by some traders

FX

Dollar index above 102; yen weaker near 157.7 per dollar

Big Tech earnings week tests whether AI spending is paying off

What Happened

Microsoft shares rose about 1.5% and Alphabet fell about 1% on Monday ahead of earnings from both companies, plus Amazon, on Wednesday and Thursday. About one-third of S&P 500 companies report this week. Investors are watching cloud growth and spending plans. Alphabet's Google Cloud revenue grew 82% from a year earlier in its last report.

Why It Matters

These companies are among the largest in the S&P 500, so their results can move the whole index. Their spending plans also show how much AI demand is real, a key question in the debate over whether we are in another AI bubble. New to investing? Learn what a stock is.

Oil stays above $100 as Middle East supply worries persist

What Happened

Brent crude slipped 0.65% to $109.92 a barrel on Monday, October 26, and US WTI fell about 1.1% to about $101. Both stayed far above year-ago levels. Brent had risen 2.8% on Friday and 3.4% on Thursday. Analysts tie the surge to renewed Houthi attacks in Saudi Arabia and the end of Iran's floating oil stocks, which had supplied Chinese refiners.

Why It Matters

Costly oil pushes up fuel and shipping costs, which can lift inflation. That is why the Fed's tone on a December hike matters so much.

Market Impact

Equities

Energy is a small slice of the S&P 500, at 3.3%

Rates

Higher oil keeps inflation fears alive for central banks

FX

Dollar firm; oil-linked inflation worries support it

Commodities

Brent fell 0.65% to $109.92 and WTI fell about 1.1% to $101 on Monday

Five central banks decide on rates this week, with US GDP and inflation data due Thursday

What Happened

The Fed, European Central Bank and Bank of Japan are all expected to hold rates this week. The Bank of Canada is expected to raise its rate to 2.50% from 2.25%, and New Zealand is also expected to raise. The dollar index rose above 102 on Tuesday as the euro slipped and the yen weakened to about 157.7 per dollar.

Why It Matters

When central banks move in different directions, currencies swing. Those swings affect the profits of companies that sell overseas.

Market Impact

Equities

Investors positioned cautiously ahead of the decisions

Rates

Fed, ECB and BoJ expected to hold; Canada and New Zealand expected to raise

FX

Euro near $1.1228; yen near 157.7 per dollar; dollar index above 102

Commodities

Gold sits in a range

Historical Perspective

Similar Event

In 2022, oil jumped after Russia invaded Ukraine while the Fed started raising rates, and stocks faced both pressures at once.

What Happened Then

The S&P 500 fell about 19% that year as higher energy costs and rate hikes squeezed growth stocks, though oil later pulled back and the market recovered.
