According to Adani, India's GDP will rise to $28 trillion by 2050 from the current $2.8 trillion, stock market valuation swelling to $30 trillion and a $10 trillion retail market. Adani expects India to be home to one in every three middle-class people in the world.
A combination of "India's soft power with the hard power of a $28 trillion GDP and a $30 trillion value stock market will give an incredible nation that is taking the journey to becoming the greatest opportunity of the 21st century," he said in his talk on 'Incredible India and the opportunities ahead for India' at the TiE Global Summit.
With the target of becoming the world's largest renewable power company by 2025, Adani said the marginal cost of electricity would continue to drop sharply as the renewable energy boom accelerates. The country will produce the cheapest electricity from renewable energy sources.
"In my view, India is today at a dramatic inflection point. I believe that over the next few decades, India will have firmly positioned itself as the greatest opportunity of the 21st century and become even stronger from the year 2050 onwards," said the Adani Group chairman.
"Yes, there will remain difficult challenges for India to overcome. But, there simply cannot be any denial of the scale of the opportunity that awaits India."
Adani said the global GDP is $85 trillion, of which India is $2.8 trillion.
"In 2050, the global GDP is expected to be $170 to 180 trillion, and the Indian GDP - then at about $28 trillion - will contribute over 15% to the global economy," he said.
"I fully expect this to be the case as a lot of the necessary structural reforms that were needed are now getting in place, and these reforms lay the foundation for accelerating our national growth."
Listing out India's advantages, Adani, who heads a ports-to-energy conglomerate, said by 2050, the country's population is expected to be 1.6 billion.

"One in every three of the world's middle-class consumers will be Indian, and India will form the largest global middle-class. This middle-class will insulate India and drive an unmatched rate of internal consumption – no nation has ever created such a massive middle class," he said.
Just the retail segment by itself will be worth $10 trillion. "India will be the target investment of every global company," he said.
The Indian stock market indexes - assuming a conservative CAGR of 9% - would have increased by a factor of 13x, putting the Sensex in the range of 6,00,000.
"Most likely, this index will be an order of magnitude higher given India's main growth is still ahead of it," he said. "I would also expect that by 2050, India would have created several of its own trillion-dollar value companies."
