Key Takeaways

- • Third Point held approximately 3.165 million shares (0.75% ownership) valued at roughly $212.82 million as of February 2026, ranking among CoStar's 15 largest investors before exiting completely.
- • The activist campaign, which began in late January 2026 with demands for board replacement and strategic alternatives for Homes.com, lasted approximately 2.5 months before Third Point determined that management had made insufficient progress on restructuring commitments.
- • CoStar's market capitalization collapsed by approximately 45% during the campaign period, falling from $28 billion to $15.3 billion, undermining Third Point's original investment thesis and forcing the fund's strategic pivot.

Summary
Daniel Loeb's Third Point hedge fund has exited its entire stake in CoStar Group and withdrawn its planned proxy fight, ending a contentious activist campaign that lasted approximately 2.5 months. The decision was communicated to investors on Friday, April 10, 2026, in a letter from Loeb stating, "We no longer believe that our original thesis holds true today and have disposed of our position in its entirety."
Third Point had accumulated a significant position in the real estate data company, holding approximately 3.165 million shares representing 0.75% ownership and valued at roughly $212.82 million as of mid-February 2026, making it one of CoStar's 15 largest investors. The fund's exit timing was strategically notable, occurring just days before the April 13 deadline for nominating director candidates for a proxy contest.
The activist campaign began in late January 2026 when Third Point issued a letter to CoStar's board demanding replacement of a majority of directors with "more qualified" candidates, refocus on the company's core commercial real estate business, and exploration of strategic alternatives for Homes.com, including potential divestiture or shutdown of the residential portal. Third Point's frustration intensified following CoStar's announcement of only a 35% spending reduction on Homes.com for 2026, which the fund deemed insufficient.
CoStar's deteriorating stock performance fundamentally undermined Third Point's investment case. The company's share price collapsed from approximately $66 in January to $36.48 by April 10, while market capitalization dropped from $28 billion to $15.3 billion—a decline of approximately 45%. In its final investor letter, Third Point stated that "so little progress has been made that we are convinced the Company never intended to do any of the things we discussed when we entered into the agreement," signaling Loeb's assessment that management had failed to deliver on prior commitments during the activist engagement period.
CoStar responded to Third Point's exit with a statement emphasizing its focus on "executing our proven playbook" and "margin expansion and profitable growth," while reiterating commitment to "unlock the tremendous value of our digital ecosystem" through continued shareholder engagement. The company had previously argued that divesting Homes.com would cause "irreparable harm" to shareholders—a position that remained unchanged despite the activist exit.
