The stock market experienced a notable downturn on Tuesday as investors sought to offload shares particularly within the software sector. This move followed increasing apprehensions that advances in artificial intelligence (AI) technologies could potentially disrupt existing software business operations.
On the S&P 500 index, the technology sector emerged as the biggest loser, contributing to a 0.8% overall decline in the index by the end of the day. The Nasdaq Composite index, which is heavily populated by technology companies, experienced a more significant drop of 1.4%.
The catalyst for the sell-off was an announcement made by AI startup Anthropic on the preceding Friday. Anthropic introduced an automated agent capable of undertaking tasks within the legal, data analytics, finance, and sales sectors.
JPMorgan Chase analysts highlighted that although AI advancements have been noteworthy over the years, the pace of progress at Anthropic has been particularly exceptional. Notably, their AI agent, Claude Code, which is adept at writing computer code, evolved from a concept to a billion-dollar product within six months.
The aftermath saw a substantial sell-off in several key company stocks. For instance, Salesforce.com witnessed a near 7% drop, while Thomson Reuters, a prominent data provider, saw a 16% descent. Similarly, real estate data provider CoStar dropped by 15%, and the London Stock Exchange Group, a vital supplier of stock market data tools, experienced a 12% plunge.
Morgan Stanley’s Toni Kaplan commented that although the product is still in its early stages, it heightens investor fears that AI-native firms might penetrate the legal tech space and pose competition to larger, more established players.
A wave of selling also impacted other data-centric companies. Intuit, owner of QuickBooks, along with S&P Global, credit data firm Equifax, HR systems provider Workday, and enterprise software company Atlassian, all saw shares drop around 10%.
Compounding the pressure on the Nasdaq was financial services giant PayPal, which reported unsatisfactory earnings alongside an announcement of a CEO change. Consequently, PayPal’s shares fell by over 20%.
In the cryptocurrency market, Bitcoin also faced substantial selling. The world’s leading cryptocurrency plummeted by almost 6.7%, reaching its lowest level since the presidential victory of Donald Trump in November 2024. Although it managed a slight recovery later, it remained over 2% down, trading around $76,600.
Interestingly, Donald Trump, initially a skeptic during his presidential campaign, appeared to be supportive of the crypto industry. This was evidenced by ventures into various crypto products by Trump and his family.
Despite these price fluctuations, Bitcoin has decreased by over 24% since last year and lost more than 12% of its value since the start of the year. This trend underscores a broader shift by investors away from assets perceived as having higher risk compared to mainstream currencies and firms.
Despite these developments, the stock market wasn’t entirely bleak. Palantir, a company thriving amidst the AI revolution, saw its stock rise more than 6% following earnings that surpassed market expectations on Monday evening. Additionally, energy stocks and those in the consumer staples sector generally climbed upwards.
