The 2008-born winger recently wrote his name into history by making his MLS debut on October 1, playing nine minutes of a 1-0 defeat to Chicago Fire.
In doing so, Hall became the youngest player to ever feature for the Red Bulls in a competitive fixture, coming off the bench at the age of just 15 years and 190 days.
In addition, the attacker also became the second-youngest MLS player in history behind Freddy Adu, who was just 14 when he made his DC United debut in 2004.
Hall has been an unused substitute for the Red Bulls in wins over DC United and Cincinnati either side of his maiden appearance, prior to which he also caught the eye in the 2023 MLS Next Pro season.
The 15-year-old came up with two goals and one assist in 10 matches in the USA reserve league, scoring one and setting up another in a 4-1 thrashing of New England Revolution II in June.
Hall made three starts at centre-forward in the regular Next Pro campaign - as well as coming off the bench in seven matches - and he also enjoyed a 30-minute run-out in a 4-1 last-16 win over the Chicago Fire II on October 1.
The New York-born protege - who is also eligible to represent Poland at international level - is now expected to be involved for the reserve team against the New England Revolution II in Friday's quarter-final showdown.
Hall signed his first professional Red Bulls deal with the Red Bulls back in September, and those terms are not due to expire until December 2026, and the club also possess the option to extend his stay by another year.
However, the American outfit may be powerless to prevent Hall moving on soon, as the Evening Standard claims that as many as five European behemoths are set to battle for his signature.
All of Chelsea, Man United and Manchester City are said to be monitoring Hall's progress, and the Blues' interest dates back to when the winger netted a brace against their Under-15s in April's Generation adidas Cup.
The Blues are apparently hoping to invite Hall to their Cobham training base for a trial, but by virtue of his new contract with the Red Bulls, any such request from the club can be blocked.
Furthermore, Real Madrid and Bayern Munich are also in the mix, although the MLS side will be able to hold out for a significant sum of money to let Hall pursue his European dream.
However, rather than head straight to one of the continent's titans, the Red Bulls could usher him towards RB Leipzig or Red Bull Salzburg, both of whom are part of a multi-club model which Chelsea are also trying to build.
