Ville de Paris (Paris City Hall, official municipal government of Paris)公式の公的記録（https://www.paris.fr/en/pages/pierre-de-coubertin-and-the-origin-of-the-olympic-games-27628）は、IOCの資本関係・沿革に関する公的記録である。None of the three existing References (what IOC is, difference from FIFA, involvement scenarios) mention the founding date, founder, or founding location, so this is a genuinely new fact.具体的には「On June 23rd, 1894, Pierre de Coubertin founded the 'International Olympic Committee' (IOC) during a ceremony at the Sorbonne University in Paris.」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 municipal government page focuses on Coubertin/Paris history and does not itself state the current Lausanne headquarters; that detail was corroborated only via preliminary lead sources (Wikipedia was used only to find leads, not as the cited source), so if Olympic House ever changes address this exactAnswer's HQ clause could go stale independent of the founding fact.2026年08月27日に同Sourceを取得し、この内容を確認した。検証待ちIOC資本関係・沿革に関する公開情報
HighRadius (Finsider financial analysis blog)公式のアナリストレポート（https://www.highradius.com/finsider/olympics-financial-strategy/）は、IOCの規制対応状況に関する第三者報道である。None of the three existing References (what IOC is, difference from FIFA, involvement scenarios) mention revenue sources, broadcast rights, sponsorship, or redistribution percentages, so this is a genuinely new fact.具体的には「61 percent of IOC's revenue is generated through the sale of its global broadcasting rights, and through its highest level of sponsorship, 'The Olympic Partners' (TOP). ... 90% of the IOC's revenue is redistributed to the global Olympic Movement: USD 4,200,000 daily to various stakeholders like Organising Committees, National Olympic Committees, International Federations, and athletes.」といった記載がある。ただし、規制対応の状況は更新されうるため、この内容は取得時点のものです。適用範囲がどこまでかは、このSourceだけでは確認できない場合があります。 Independent sports-finance journalists (e.g. insidethegames.biz) have publicly questioned whether the '90% redistributed' framing is fully accurate or somewhat misleading (arguing under 0.5% goes directly to athletes); this source repeats the IOC's own stated framing without that critical caveat, so the figure should be read as the IOC's official claim rather than an independently audited number.2026年08月27日に同Sourceを取得し、この内容を確認した。検証待ちIOC規制対応状況に関する公開情報
