HubSpot Shares Surge as AI Strategy Gains Traction, But Short Sellers Circle

HubSpot shares jump 14% as AI-driven strategy lifts sentiment, but short interest and insider selling signal caution ahead of May earnings.

HubSpot’s stock jumped more than 14% to €216 on Tuesday, as investors cheered the company’s deepening commitment to artificial intelligence. The rally comes ahead of first-quarter results due in May, with the CRM specialist betting big on its transformation into an “Agentic Customer Platform” that automates marketing and sales workflows.

The optimism marks a sharp shift in sentiment. Just weeks ago, the shares were trading near their lows for the year, weighed down by a 34% decline since January. The Relative Strength Index had dipped to 27, a level typically considered oversold, which likely drew in bargain hunters.

Revenue Growth Remains Robust

HubSpot generated $846.75 million in revenue during the first quarter, representing a 20.4% increase year-over-year. Adjusted earnings per share came in at $3.09, comfortably above analyst expectations. For the full year 2025, the company booked total revenue of $3.13 billion, setting a high bar for the current period.

Wall Street is looking for first-quarter earnings of roughly $2.47 per share on sales of about $863 million. The company ended the most recent quarter with over 288,000 customers, up 16% from a year earlier. That customer expansion will be closely watched as a barometer of the AI-driven strategy’s success.

Short Interest Climbs Despite Strong Fundamentals

Not everyone is convinced. Short interest rose 18.6% in the month to mid-April, with 3.61 million shares sold short — representing about 7% of the free float. The elevated bearish bets reflect lingering skepticism about whether HubSpot can sustain its growth trajectory.

Insider selling has added to the unease. Over the past three months, executives have offloaded roughly $6.6 million worth of stock. One director sold more than 8,000 shares at around $231 apiece in late April.

Analyst Views Diverge

The analyst community remains split. Macquarie reaffirmed its “Outperform” rating, citing confidence in the company’s product pipeline and strategic direction. But other firms have trimmed their price targets. Citigroup now sees the stock at $321, while Mizuho lowered its target to $300. The average analyst price target stands at $388.

Institutional investors are also taking opposing positions. Jennison Associates nearly exited its stake entirely, while Strs Ohio boosted its holding by more than 28%.

Technical Signals Point Both Ways

The stock’s volatility has spiked to nearly 70%, underscoring the uncertainty. Despite Tuesday’s surge, the shares remain down roughly 34% year-to-date at €205 in European trading. The RSI reading of 27 suggests the stock may still be oversold, though the heavy short interest indicates many traders expect further downside.

The May earnings report will serve as a critical test. HubSpot must demonstrate that its AI investments are translating into sustained customer growth and margin improvement. If the numbers disappoint, the short sellers could tighten their grip. But a strong beat might force them to cover, fueling another leg higher.
