Wall Street Rebounds Monday as Anthropic IPO Filing Lifts Nasdaq Ahead of Fed Week

US stocks staged a decisive reversal on Monday, October 26, 2026, ending a two-session slide as investors positioned for the busiest week of America’s corporate and monetary calendar. The S&P 500 rose 53.09 points, or 0.70%, to 7,676.77, the Dow Jones Industrial Average gained 146.42 points, or 0.28%, to 52,361.58, and the Nasdaq Composite added 214.04 points, or 0.82%, to 26,169.38, according to market data tracked by Yahoo Finance and Reuters.

The advance reversed Friday’s slate, when the S&P 500 had shed 0.52% to 7,623.68 as investors digested oil costs and a revived debate on artificial-intelligence valuations. Monday’s session was driven less bymacro news and more by a corporate surprise: technology-focused AI company Anthropic filed for an initial public offering that plans a Nasdaq listing under the ticker ANT, a report carried by Nairametrics and widely credited with lifting technology sentiment at the open.

The VIX volatility index fell 5.45% to 18.39, its sharpest single-day decline in recent sessions, while the 10-year Treasury yield eased marginally to about 4.99%, suggesting investors were willing to add risk even as they waited for the Federal Reserve’s decision on Wednesday, October 28.

Chips Lead; Anthropic Crowds the AI Lens

Bloomberg reported that a revival of the artificial-intelligence trade powered the session, with chipmakers rallying and the closely watched Philadelphia Semiconductor Index rising 2.8%, while the Nasdaq 100 gained about 1.1%. Semiconductor stocks have been the market’s most sensitive barometer for AI-related capital spending, and Monday’s move suggested investors read the Anthropic filing as confirmation that listed AI leaders — not just public issuers — are preparing to come to market.

The filing lands in the middle of a week investors have described as “formidable” for risk assets. Beyond the Fed, the earnings calendar features Amazon, Microsoft and Alphabet among the mega-cap reporters, according to Reuters’ Asian-session coverage, meaning the single week will set the tone for the AI investment debate into the November close.

The Fed Question That Frames the Week

Rate expectations have shifted uncomfortably in recent sessions. Market commentary tracked by FXStreet showed traders broadly pricing a Federal Reserve pause at the October 28 meeting, after which attention turns to December, where the probability distribution between a hold and a further move remains contested. US Treasury yields near 5% have lubricated that debate, keeping bond-market volatility in investors’ peripheral vision even during equity upswings.

For Nigerian and African investors with dollar exposure, the Fed week carries a second-order effect: a hawkish surprise would likely strengthen the dollar and pressure emerging-market rates, while a neutral statement with patient forward guidance would keep the-year’s emerging-market carry trades intact into year-end.

Anthropic’s Filing and the IPO Wave

The reported filing by Anthropic — one of the most prominent private of the young AI generation — echoes a pattern investors have watched all autumn: large private technology companies testing public markets as index valuations hover near record highs. Editorial commentary throughout October has weighed AI-investment concentration against earnings delivery, and a marquee IPO would give institutions a fresh way to express the theme without buying stretched incumbents.

Listing details remain subject to the formal prospectus and pricing process, and shares are not yet on offer. What matters near-term is sentiment, and Monday showed it: the same tape that wobbled on Friday on AI-doubt headlines ended 0.82% higher once a credible new AI entrant signalled public-market intentions.

What to Watch Through Friday

Three checkpoints will decide whether Monday’s bounce holds. First, Wednesday’s Fed statement and press conference, where the balance-of-risks language will steer December expectations. Second, the mega-cap results, which will test whether 2026’s AI-spending narrative can still lift operating margins. Third, crude oil, which finished Monday lower as Middle East diplomacy intensified; renewed escalation would reprice inflation assumptions and squeeze risk appetite exactly when the market needs stability most.
