As per the Protocol, for the 36th edition of the America's Cup, the Challenger of Record (COR36) shall be responsible for organising all the preliminary regattas including the America's Cup World Series (2019–2020), the Christmas Race (December 2020) and ultimately the America’s Cup in Auckland.

The boats will be in the AC75 class and will be monohulls featuring foils and "soft wing" mainsails.
The event will take place between 6–21 March 2021. 
Entries for challengers opened on 1 January 2018 and closed on 30 June 2018 with late entries accepted until 30 November 2018. The America's Cup World Series will be held in 2019 and 2020 with a Christmas regatta in December 2020. The Challenger series will be held in January and February 2021 with the America's Cup match in March.
Prior to Emirates Team New Zealand winning the 35th America's Cup in 2017, Oracle (the defender at the time) and four of the five challengers had signed a framework that would have seen the 36th America's Cup in 2019 and the 37th in 2021, with the existing 35th Cup class boats, the AC50s, and a pre-selection America's Cup World Series tournament with the same boats. Team New Zealand, the eventual champion, had opted to not sign the framework agreement, and were not bound by its terms, freeing them to set their defence for 2021, while also choosing the AC75 boats, in hope of making the competition more attractive to sailors.
Circolo della Vela Sicilia is the "Challenger of Record" for the 36th America's Cup. Their team, Luna Rossa Challenge is led by Max Sirena, had previously lost to Emirates Team New Zealand in the 2000 America's Cup and the 2007 and 2013 Louis Vuitton Cup finals.
The New York Yacht Club (NYYC) has entered AC36, under the syndicate name American Magic, with a team led by Terry Hutchinson and Bella Mente Quantum Racing Association. In May 2018 it was announced that Dean Barker would helm the boat. "American Magic" refers to the first Cup winner, the yacht America of 1851, and the first defender, NYYC's yacht Magic, who successfully defended in 1870. The America's Cup trophy was held by the NYYC for 132 years until 1983. The NYYC successfully defended the trophy twenty-four times in a row before being defeated by the Royal Perth Yacht Club, represented by the yacht Australia II. The NYYC's reign was the longest winning streak (in terms of date) in the history of all sports.
At the close of the late entry notice period, 30 November 2018, eight notices of challenge were submitted to the defender, and they will be processed in order of reception. By the end of year 2018, three of those challenges have been accepted: Iain Percy and the Royal Malta Yacht Club; a second American challenge from Taylor Canfield and the Long Beach Yacht Club; and a national challenge from the Netherlands issued by Royal Dutch Yacht Club.
On 2 April 2019, the New York Yacht Club, through team American Magic, filed for arbitration relating to the acceptance of the three late entry teams. On 15 March 2019, the America's Cup Arbitration Panel released their decision denying American Magic's application and allowed the late entry teams to compete.
On 31 May 2019, the Royal Malta Yacht Club announced that they were withdrawing as challenger. 
On 1 July 2019, the Koninklijke Nederlandsche Zeil- & Roeivereeniging announced that are also withdrawing as challenger, whereas the Long Beach Yacht Club confirmed their ongoing commitment.
