Endrick is set to join US sportswear brand New Balance ahead of his transfer to Real Madrid.
The Palmeiras youngster, 17, agreed to join Real in December 2022, despite the fact that regulations only allow him to officially move to the Spanish club in the summer of 2024, when he turns 18.
The Athletic has learned that the attacker was under contract with Nike until February 2023. After that date, the sports brand had a six-month preferential option to extend the link.
Rival sponsors were conscious that Nike, which has renewed its deal with Vinicius Junior until 2030, could match any terms they offered.
Following this period talks accelerated from September onwards with different brands with New Balance impressing the player with the prominence they will give him and a fit more suited to his age and image.
New Balance assures Endrick of a spotlight that brands such as Nike (Cristiano Ronaldo, Kylian Mbappe and Erling Haaland), Adidas (Lionel Messi and Jude Bellingham) or Puma (Neymar) would find difficult to match.
They will now be his main sports sponsor for the next five years, until 2028.

Endrick will join Real Madrid in July 2024. He will prohibited from training with the squad, until the 21st of that month (when he turns 18) but will meet with his new team-mates.
He could yet be called up by Brazil for the Copa America (from June 20 to July 14 in the United States). In this case, Endrick would have more time off and could join the team later, probably straight in the preseason tour, as would his compatriots Vinicius Junior, Rodrygo and Eder Militao.
Endrick was called up by Brazil for the first time this month, being included in Fernando Diniz’s list for the qualifiers against Colombia and Argentina becoming the youngest player to be called up since Ronaldo Nazario in 1993.
The attacker was rewarded for his improvement with Palmeiras, for whom at the time he had scored three goals in two games in November.
The Athletic understands that Real Madrid have to pay €2.5million to Palmeiras for every five goals he scores, up to a maximum of 25. With the current 12, Real Madrid have to pay €5m.
In the agreement for his signing, for a fixed €35m fee plus €25m in variables, bonuses were also included for the first call-up with Brazil and a first appearance for his national team as well as further add-ons following his arrival in Spain, related to others with his playing time.
The deal has already exceeded €40m but Real see the increase as a positive sign the player is progressing as much as he is expected to.
