The transfer looks to be a big statement of intent from the Seagulls as they prepare for a third successive season in the Premier League after narrowly escaping relegation in 2018/19.
The record arrival of Trossard will be the second signing for new manager Graham Potter after the recent capture of 22-year-old defender Matt Clarke from Portsmouth.
According to information from Belgian outlet HLN Sport, the fee Brighton have agree with Genk for Trossard is around £18m. It will therefore surpass the reported £17m previous record fee that was paid for flop signing Alireza Jahanbakhsh just 11 months ago.

A report from the Daily Mail carrying quotes from Genk chief executive Erik Gerits notes that agreeing personal terms with Trossard is expected to now be a 'formality'.
"Everything took place in a correct and constructive atmosphere, with a lot of mutual respect. In fact, discussions about a transfer should always be this way. Now Leandro has to decide for himself," Gerits said of the amicable negotiations with Brighton.
Trossard, 24, is a product of the Genk youth academy and spent time on loan at a handful of other Belgian clubs before breaking into the first team in 2016.
Following an injury hit campaign in 2017/18, Trossard enjoyed his best season yet in 2018/19, finishing with 33 combined goals and assists in all competitions and emerging as captain.
Genk have a fine reputation for developing talented players, whether home grown or otherwise, with Kevin de Bruyne, Thibaut Courtois, Kalidou Koulibaly, Sergej Milinkovic-Savic, Wilfred Ndidi, Christian Benteke and Christian Kabasele among those to have passed through.
