Major United States asset manager Grayscale has just surpassed $50 billion in cryptocurrency assets under management for the first time. Grayscale’s AUM is creeping ever closer to the $57-billion holdings of the largest commodity ETF.

The company has plans to convert into an ETF when regulations allow. 

If the ETF had been approved already, Grayscale would be the second-largest commodity ETF behind SPDR Gold Shares. GLD is a physically backed gold exchange-traded fund with listings on stock exchanges in the U.S., Mexico, Singapore, Japan and Hong Kong.

Grayscale CEO Michael Sonnenshein tweeted that he believes the Grayscale Bitcoin Fund is likely to surpass the GLD fund by market cap in a few months.

Grayscale provides cryptocurrency exposure to institutional investors and holds approximately 660,000 Bitcoin

$22,875

 in total representing 3.5% of Bitcoin’s 18.68 million circulating supply. Almost 655,000 of these are held in Grayscale’s Bitcoin Trust.

Grayscale doesn’t just deal in Bitcoin, with almost 20% of the company’s AUM spread across a dozen other cryptocurrencies including Ether

The firm is already the largest U.S. digital asset manager by a large margin, with Pantera, the second-largest manager, holding only $4.3 billion, less than one-tenth of the $50 billion held by Grayscale.

On Wednesday, the asset manager announced a partnership with Time Magazine to produce an educational crypto video series. The magazine also agreed to receive payment in Bitcoin and hold the digital asset on its balance sheet.
