Activist Investor Sachem Head Builds 6% Stake in Rightmove

US activist investment firm Sachem Head has acquired a 6% stake in Rightmove, worth hundreds of millions of pounds, according to reports from The Sunday Times. The move has prompted speculation about the property portal's future ownership.

The investment comes as Rightmove's share price remains significantly below its 2025 peak. Shares fell from £8.18 in summer 2025 to a low of £4.10 in May this year, and currently trade at approximately £5.00, a 39% decline from their high point.

Why the share price fell

The decline followed market concerns that AI-enabled search engines, particularly ChatGPT, could disrupt Rightmove's dominance in online property search. The company's November trading results failed to reassure investors, accelerating the share price decline through the first half of this year.

Market sources suggest Sachem Head believes the AI-prompted sell-off was excessive and that the shares are now undervalued. The hedge fund has reportedly been encouraging Rightmove to take on debt to fund share buybacks, a strategy that could support the share price.

Takeover speculation

This is the second time in recent months that Rightmove has attracted activist investor attention. The 6% stake gives Sachem Head a significant position from which to influence company strategy or potentially launch a takeover bid.

Industry observers note that the short-term threat from AI to Rightmove's business has not materialised as feared, potentially validating the fund's thesis that the market overreacted to the technological disruption narrative.

Rightmove has not yet responded to requests for comment on the stake acquisition or the speculation surrounding potential corporate action.

What it means for agents and clerks

Property industry professionals who rely on Rightmove for marketing listings and generating buyer enquiries will be watching its performance closely. Any change in ownership or corporate strategy at the UK's leading property portal could affect how agents market stock and manage enquiries going forward.
