Anthropic IPO filing discloses first-of-its-kind governance structure

US equities finished higher on Monday (Oct 26) as the debut of AI-focused startup Anthropic buoyed sentiment in the artificial intelligence sector amid a week filled with various market catalysts. The S&P 500 and Nasdaq both recovered from two consecutive weekly declines, marking a positive end to the trading day. Anthropic's IPO filing disclosed substantial revenue growth despite steep losses, outlining its goal to develop AI systems that could transform the global economy despite the high costs of the technology.

The AI firm proceeded with its listing plans even as the market has slowed down on IPO activity due to recent volatility. This filing comes as investors focus on the potential returns from substantial AI investments and the beginning of an eventful week with the US Federal Reserve's policy statement, economic growth and inflation data, and corporate earnings reports.

Over a third of S&P 500 companies are set to report earnings this week, with hyperscalers Alphabet, Microsoft, and Amazon to be analyzed for signs of whether their significant AI investments are yielding growth. JP Powers, chief investment officer at RWA Wealth Partners in Boston, noted that there is a risk of a "whipsaw" if the market reactions are not uniform, but expressed optimism about the Anthropic release.

The Dow Jones Industrial Average gained 146.42 points, or 0.28 percent, to 52,361.58, while the S&P 500 rose 53.09 points, or 0.7 percent, to 7,676.77. The Nasdaq Composite added 214.04 points, or 0.83 percent, to 26,169.38. Semiconductor and chip-related companies, considered major beneficiaries of the AI boom, contributed to the gains, with the Philadelphia chips index up 2.8 percent on the day, though still down 12.2 percent for the month.

Meta shares decreased by 1.9 percent after announcing plans to raise up to $95 billion in equity to support its AI-related expansion of data centers, cloud computing power, and other infrastructure. The AI trade faced pressure in October due to concerns about debt-funded spending becoming harder to justify amid rising borrowing costs.

However, the Anthropic filing helped lift sentiment, as neocloud firms like CoreWeave erased earlier declines. Other AI-linked companies, including photonic product makers Lumentum and Coherent, were among the top-performing S&P 500 stocks, gaining around 8 percent and 6 percent, respectively. The technology sector led gains among the 11 major S&P 500 sectors, surging 1.5 percent.

Megacap and growth stocks also mostly performed better. Tesla surged 5.2 percent, reaching its highest level in over three months after Barclays upgraded its rating on the stock to "overweight" from "equal-weight". Market participants are pricing in only a 12.7 percent chance of a rate hike from the Fed on Wednesday, according to CME FedWatch.

Inflation pressures remain, and there is little confidence that the central bank will remain idle for long. Investors are also preparing for the Nov 3 midterm elections, which will determine control of the US Congress. Advancing issues outnumbered decliners by a ratio of 1.36-to-1 on the New York Stock Exchange and 1.09-to-1 on the Nasdaq.

The S&P 500 recorded seven new 52-week highs and seven new lows, while the Nasdaq Composite noted 82 new highs and 349 new lows. Trading volume on US exchanges reached 16.7 billion shares, compared to the 17.2 billion-day average over the last 20 trading sessions.
