Jack Ma's net worth fell by about $3 billion ($48 billion) on Tuesday, according to Bloomberg's Billionaire Index, after the delayed Ant Group IPO sent shares of Alibaba down by as much as 10%.

Alibaba owns 33% of Ant Group, and Jack Ma owns 4.2% of Alibaba, which has a market capitalization of about $775.5 billion. 

Ant Group was set to go public via a dual listing on the Hong Kong and Shanghai exchanges this week in what was expected to be the largest IPO in history. Ant Group was set to raise nearly $35 billion in proceeds from the offering.

The deal was set to be so big that it attracted $3 trillion in bids, or roughly 872 times the exchange's supply of shares.

The suspension of the Ant Group IPO came one day after Ma and two top executives of Ant Group were summoned to meet with Chinese regulators. According to Reuters, regulators told the trio that Ant's "lucrative online lending business would face tighter government scrutiny."

Still, even with today's drop in shares of Alibaba, Ma is still worth about $54 billion, according to Bloomberg.
