Previously, Musk's Twitter posts have been a major driver of interest in the cryptocurrency.
According to CoinDesk, a cryptocurrency price tracker, Dogecoin's market capitalisation is $65.8bn, bigger than Ford, Heinz and Twitter. Its price has risen from $0.0054 at the start of the year to $0.515 on Tuesday.
Created in 2013 by former Adobe and IBM software engineers, Dogecoin is a reference to a popular internet meme featuring the Shiba Inu dog breed.
Its market value is much smaller than Bitcoin, which has a total value of $1.06 trillion. There is no limit on the number of Dogecoins that can be mined.
Records show that an anonymous person or entity controls around 28 per cent of all the Dogecoin in circulation, a stake worth more than $2bn. The opacity of cryptocurrency means it is difficult to decipher its owners.
