Michael Alan Spencer, Baron Spencer of Alresford (born 30 May 1955), sometimes known as "Spence", is a British billionaire businessman and philanthropist. He is the founder of NEX Group, a UK-based business focused on electronic markets and post-trade business which was acquired by CME Group in November 2018. NEX Group was formerly known as ICAP, until the sale of its voice-broking business to Tullett Prebon in December 2016.
