AI Growth Stock HubSpot Plummets 11% in a Day, Losing 2 Trillion Won

HubSpot Inc. (NYSE: HUBS), a marketing automation software company, saw its shares plunge 11% to $282.24 on the 29th at the New York Stock Exchange, cutting its market capitalization to about $14.7 billion (roughly ₩20 trillion). In a single day, the company wiped out approximately $1.46 billion (about ₩2 trillion) of market value, with trading volume topping 2 million shares. Nasdaq reported that HubSpot’s Relative Strength Index (RSI) had fallen to 26, entering traditional “oversold” territory.

In the third quarter of 2025, HubSpot delivered an “earnings surprise,” with revenue rising roughly 20% year-over-year and adjusted EPS beating market expectations. The company subsequently raised its full-year revenue and profit outlook, earning praise for its solid fundamentals. Nonetheless, concerns over slowing growth and high valuation have weighed on the stock, which has slid about 20% since its November 2025 earnings release. Volatility is now on the rise ahead of its fiscal fourth-quarter results, scheduled for mid-February.

Founded in 2006 by a group of MIT alumni, HubSpot is a U.S.-based SaaS provider offering an all-in-one marketing, sales, and customer management platform for small and midsize businesses. It is widely regarded as one of Salesforce’s main competitors in the CRM market. Under CEO Yamini Rangan, the company has adopted an “AI-first” strategy, embedding artificial intelligence deeply across its product suite. The recent sharp decline in HubSpot’s stock underscores just how sensitive investor sentiment remains toward high-growth software names.
