Compass公式のプレスリリース（https://www.compass.com/newsroom/press-releases/1BXJXfaH0Sfi04DXIpFIgA/）は、Compassの資本関係・沿革に関する一次情報である。Existing References describe Compass only as a generic US tech-enabled brokerage and compare it to Keller Williams; none mention the IPO, so this is not a duplicate.具体的には「"Compass, Inc. (Compass) today announced the pricing of its initial public offering of 25,000,000 shares of its Class A common stock at a public offering price of $18.00 per share." ... "The shares are expected to begin trading on the New York Stock Exchange on April 1, 2021 under the ticker symbol 'COMP.'"」といった記載がある。ただし、この記述は当該Sourceの時点のものであり、その後の変更が反映されているとは限りません。 This is a self-published corporate press release announcing the IPO pricing; it does not itself verify subsequent trading history or whether all terms executed exactly as priced (independent financial sites corroborate the April 1, 2021 NYSE listing under COMP).2026年08月26日に同Sourceを取得し、この内容を確認した。検証待ちCompass資本関係・沿革に関する公開情報
Chicago Sun-Times公式の報道記事（https://chicago.suntimes.com/real-estate/2024/12/03/real-estate-giant-compass-acquires-chicago-properties-christies-444m-deal）は、Compassの戦略的方向性に関する第三者報道である。Not covered by existing Compass References, which only address the generic definition, the Keller Williams comparison, and the tech-driven brokerage use case; distinct from finding 1 (IPO) in claim, evidence, and source.具体的には「"Compass announced Monday that it will acquire @properties, Christie's International and its title, mortgage and lead-generation business," valued at "$444 million, with $150 million in cash and $294 million in equity," and noting "@properties has grown to be the 8th largest U.S. brokerage by sales volume."」といった記載がある。ただし、これは当該Source公表時点の方針表明であり、その後変更される可能性があります。 This article (Dec 2024) describes the deal at announcement stage, 'expected to close in 2025 pending regulatory approval'; it does not itself confirm completion. Other reporting indicates the deal closed in Jan 2025, and Compass subsequently combined with Anywhere Real Estate in Jan 2026 to form Compass International Holdings — a further change not captured in this source.2026年08月26日に同Sourceを取得し、この内容を確認した。検証待ちCompass戦略的方向性に関する公開情報
