He says top three vendors could hold 80% of PC market within five years.
Dell chief executive Michael Dell has said that the top three PC makers could increase their market share in the future via integration.
According to research firm IDC, Lenovo, HP and Dell have 20.3%, 18.5% and 14.5% of the PC market share, respectively.
Dell said together, the top three firms could generate around 80% of the market share over the next five to seven years.
He said: "In the first half of the year we outgrew the other two companies in notebooks. In 10 quarters in a row we continued to gain market share."
Last month, IDC predicted PC shipments to decline 8.7% this year, steeper than its previous estimate of a 6.2% drop. The return to growth is anticipated in 2017.
Dell suffered a huge blow due to a declining PC market as consumers shifted to tablets and smartphones.
The PC maker decided to go private in a $24.9bn buyout deal in 2013, a deal engineered by its CEO and Silver Lake Partners.
Dell said going private allowed the company to focus more on the long-term instead of the short-term success.
"Being a private company has certainly allowed us to focus our future more on 3 years, 5 years, 10 years out and get away from the short-term orientation that public companies often find themselves in," Dell said.
Reported by Reuters, Dell made the above comments in a roundtable conference with journalists in Bengaluru, India.
