Tyson Fury's fortune almost doubled from £82.3 million to £162 million last year, it can be revealed.
Fury's boxing company show reserves rocketed by £80 million after his first fight with Oleksandr Usyk in May last year.
But despite the mega boost to his worth Fury took a modest dividend payout of £100,000 compared to £150,000 the year before.
Details are published in accounts for Tyson Fury Limited which channels the boxer's income from fights in the 12 months up to the end of September last year.
The company holds cash reserves of £7.5 million, but the bulk of his fortune is held in unspecified investments which rocketed to £176.7 million from £108.8million.
The overall value of his fortune is reduced because creditors are owed just over £28 million.


Fury lost the World Heavyweight bout with Usyk in May last year, and was defeated a second time in a rematch in December.
The figures for the second bout, also fought in Riyadh, Saudi Arabia, are not included in the latest accounts.
And that means that his fortune is now likely to be way in excess of £200 million.
The financial details mean that firm's financial clout is now very close to London rival Anthony Joshua's fortune.
Joshua's Sparta Promotions Limited is worth almost £150 million and his 258 Marketing Limited £35 million.
Last week friends of Fury said he was definitely retired although he was not at peace after the controversial loss to sky in December which was decided by three judges scoring his rival as the winner.
He told WBC president Mauricio Sulaiman he was glad to have quit.
Sulaiman said: 'I call him regularly and he said: 'Oh I'm so happy, retired, I'm here with my wife. 'He didn't hint whatsoever that he was planning on coming back.

'He told me he was not happy with the decision in the second fight with Usyk.
'He's still very bitter about the judges' scoring and he was very upset but he was retired, that's what he said.'
