March 4 (Reuters) - Walmart Inc-owned Indian e-commerce company Flipkart is looking at going public in the United States through a merger with a blank-check company, Bloomberg News reported on Thursday, citing people familiar with the matter. Flipkart has reached out to several special purpose acquisition companies (SPACs) and could seek a valuation of at least $35 billion in a blank-check deal, the report here said. Both Flipkart and Walmart did not immediately respond to Reuters requests for comment. Reuters reported in September that Bengaluru-based Flipkart, which vies with players such as Amazon.com’s local unit and India’s Reliance Industries, was preparing for an initial public offering overseas as early as 2021.
