The deal with Mirae is expected to be finalised in the coming days before the deadline for the closing of the Twitter deal on Oct 28, the source added.
Mirae Asset earlier this year invested in Musk’s rocket and satellite company SpaceX, the person said.
Musk’s lawyer and Mirae Asset were not immediately available for comments.
The Korea Economic Daily earlier reported Mirae Asset’s investment plan for Twitter.
Analysts say Musk needs to attract more equity investors to finance the Twitter purchase and avoid further sales of his stock in electric carmaker Tesla.
Earlier this month, a Delaware judge gave Musk until Oct 28 to close his takeover of the social media platform.
Tesla investors have feared the billionaire might sell more Tesla stocks to finance the deal, weighing on its shares.
