Indian industrialist Gautam Adani has reclaimed his spot in the $100 billion club, crossing the threshold once again after his business empire&#39s share prices collapsed last year amid allegations of fraud. The Adani Group now stands exonerated of all charges.According to the Bloomberg Billionaires Index, Mr Adani currently ranks as the 12th richest person globally with a net worth of $101 billion.Valued at over $150 billion previously, the Adani Group saw its share prices plummet in 2022 following a damning short-seller report. However, the conglomerate has regained much of its lost value after being cleared by the Supreme Court and market regulators.Adani labelled the claims made by Hindenburg Research as malicious combination of selective misinformation and concealed facts relating to baseless and discredited allegations to drive an ulterior motive.At his lowest point following the report, the ports-to-energy tycoon&#39s wealth sank to $37.7 billion, shedding around $80 billion. This year so far, he has recouped over $16 billion, according to Bloomberg data, though he remains roughly $50 billion below his 2022 peak.In a major vindication for the company in January, the Supreme Court upheld market regulator SEBI&#39s clean chit to the Adani Group, ruling out the need for any further investigation.
