Entering India has proven problematic for retailers, thanks to strict laws governing international operators in that market. Walmart does operate wholesale stores there but isn't permitted to sell direct to consumers.
Flipkart is India's biggest online seller.
Walmart could be willing to invest roughly $1 billion in Flipkart, according to reports.
Walmart had been looking to partner with China's JD.com to jump starts-commerce sales there, but ultimately sold its online business to JD and took a 5 percent stake in that business.
In the United States, executives have been keenly focused on growing digital sales and Walmart's $3 billion buyout of Jet.com is intended to do just that.
