Bansal transferred more than 539,000 of his Flipkart shares to Walmart's Luxembourg-based entity -- FIT Holdings SARL, according to business intelligence platform Paper.vc.
"Our data, derived from Flipkart's filings, indicate that with this transfer, Binny Bansal has monetised a small portion of his shareholding for what appears to be a cash consideration of $76.4 million," it added.
The current sale is estimated to have reduced Bansal's holding from 3.85 per cent to 3.52 per cent.
Walmart Inc, in May last year, had announced that it is buying 77 per cent stake in Flipkart for about $16 billion (Rs 1.05 trillion), its biggest deal that gave the US retailer access to Indian e-commerce market that is estimated to grow to $200 billion within a decade.
Reaction from Binny Bansal could not be ascertained.
According to Paper.vc, Binny Bansal had sold shares for about $159 million during the Walmart takeover. Sachin Bansal had sold his entire stake.
After the deal, Binny Bansal continued to lead Flipkart as Group CEO and co-founder till November last year, when he resigned following a probe into an alleged "serious personal misconduct". Binny had strongly denied the allegation and the independent investigation done on behalf of Flipkart and Walmart "did not find evidence to corroborate the complainant's assertions against Binny".
