Floyd Mayweather reveals £516,000 betting win to fans

Mayweather, who is no stranger to flaunting his wealth as this extensive slideshow demonstrates, told his fans on Instagram that “the last four days have been great”, before adding “I don’t do anything for free”.

His message accompanied an image which showed four sporting bets he placed over the course of the past week which combined to bring him $827,000 (£516,000).

The huge win is not the first for regular gambler Mayweather, who has treated his lucky fans to examples of his fortune – or perhaps skill – in the market many times previously.

The 38-year-old unbeaten boxing champion's series of bets consisted of a mix of basketball matches and the fight between Gennady Golovkin and Willy Monroe.

Back in October, Mayweather won £2.48 million as part of a winning streak betting on NFL games, while he also collected £966,000 on the Arizona Cardinals beating the Oakland Raiders having wagered a staggering £495,000 on the match.

American Football has seemingly always proved to be profitable for Mayweather, who also bet £518,000 on the Denver Broncos to beat the New York Jets last season, duly winning £916,000.

Oh, and in 2013, Mayweather laid down a whopping £3.75 million on the Miami Heat beating the Indiana Pacers in an NBA game, taking a profit of £4.13m back to his mansion.

The betting wins are clearly a tidy side earner for the American, who earned a reported $200 million (£125m) from beating Manny Pacquiao in Las Vegas on May 2 in what was billed as the 'fight of the century'.

Like most gamblers talking up their winnings, Mayweather only ever seems to tell the world about his successful punts AFTER they've come in. When he starts sharing his tips beforehand, then we'll be impressed; as it is, we're just going to sit here and assume that the boxer probably loses at least as often as he wins.
