The youngest and only boy of four children, Arndt attended Hotchkiss School, a private school in his native Connecticut, and won a fellowship to a 13th year at Harrow College in Northwest London. He earned his undergraduate degree in history, with honors, at Yale University in 1990, where he was captain of the golf team. He worked for five years as an investment banker for Morgan Stanley as well as in the entertainment industry in Los Angeles. He then entered Harvard University for an MBA in 1996.

''The Amazing Race''
Arndt and former partner Reichen Lehmkuhl competed against eleven other teams the fourth season, taped in January and February 2003, and premiering in May. The couple, who had met in 1999 while Reichen was still in the United States Air Force, had a commitment ceremony on February 2, 2002. While not legally married, they had asked that CBS identify them as a married couple. The identification of a gay couple as married drew criticism from anti-gay groups. By the final episode, Reichen and Chip had an 83% popularity rating on the show's official website. Arndt performed seven of eleven roadblocks. In total, they placed second on five legs of the race, with their win on the final leg being their second first place, eight minutes ahead of runners up Kelly and Jon. The finale was broadcast on August 21, 2003, with CBS winning both its time slot and the night. Season 4 would later win an Emmy award for Outstanding Reality-Competition Program.

Each year, Arndt conducts a golf clinic at the Advocate Golf Classic benefiting the National Gay & Lesbian Task Force. As the former Public Relations and Marketing Manager for Care Resource, South Florida's oldest and largest HIV/AIDS services organization, he produced the 2005 AIDS Walk Miami, and spearheaded the 21st annual White Party, its week-long fund-raiser, which, at his initiative, emphasized a zero tolerancedrugs policyfor the first time.
