Groves is the reigning WBA super-middleweight world champion, having won the title by beating Fedor Chudinov back in May last year.
He went on to successfully defend the belt in the quarter-final of the World Boxing Super Series, beating Jamie Cox to reach the last four.
Eubank Jr joined him with a win away in Germany, knocking out Avni Yildrim in just the third round to set up the grudge match.
The prize money arrangements for the World Boxing Super Series are a little different from usual bouts, with the organisers announcing at the beginning of proceedings that the prize fund for the entire super-middleweight tournament would be just under £20million.
They also confirmed that the purses for each round would be progressively larger, naturally, with the winner of the final taking the biggest payday of all.
The purse for each of the semi-final bouts is expected to be around £3m and will be split down the middle between the fighters.
The winner will then be guaranteed yet more cash because he will fight in the final, either against Callum Smith or Jurgen Braehmer, who face off on February 24.
The purse for the final is expected to be up around £6.5m with the winner taking £4.3m and the loser taking £2.2m.
And WBSS promoter Kalle Sauerland has insisted that those figures will not change depending on pay-per-view sales: the prize money is decided in advance and agreed upon in black and white.
“We have invested a lot of money to try and not be too like boxing,” Sauerland said.
“If you look at Wimbledon, would Roger Federer get a bonus because Swiss TV paid extra? He’d get prize money, like fighters will here.”
In addition to a total of three seven-figure paydays throughout the rounds, the super-middleweight champion will also take home the commemorative WBC “Diamond” belt as well as the Muhammad Ali Trophy.
