CORRECTION (29 November 16:21 UTC): A previous version of this story incorrectly reported that that Coinbase had acquired Tagomi for $150 million.

Coinbase has not agreed to acquire the crypto brokerage Tagomi.

"There is no acquisition planned," Rachael Horwitz, from the Coinbase communication team told CoinDesk in an email.

"The rumor of Coinbase acquiring Tagomi is not true," a Tagomi spokeswoman also confirmed.

San Francisco-based cryptocurrency exchange Coinbase was said to have acquired prime broker Tagomi for $150 million, according to a source who claimed familiarity with the matter.

Tagomi, which has raised $28m in venture capital funding from firms like Pantera and Morgan Creek, was reported by The Block on Nov. 15 to be in acquisition talks with Coinbase.

“Tagomi and Coinbase were in talks last week – well Coinbase acquired Tagomi this morning for $150 million,” a source who claimed knowledge of the deal told CoinDesk. Both companies denied any acquisition subsequent to the story's publication. A source at Tagomi told CoinDesk that the two companies have had negotiations about doing business, not acquisitions.

Coinbase and Tagomi had not returned requests for comment by press time.

Tagomi was founded last year by ex Goldman traders and former Union Square Ventures employees.

Just days ago, the firm teamed up with Binance.US, the U.S. partner of the Malta-headquartered Binance cryptocurrency exchange, to bring extra liquidity. It's also one of less than 20 crypto companies to have been granted the notoriously hard to acquire New York "BitLicense."

Coinbase Prime, the exchange’s institutional trading platform was launched last year to attract Wall Street capital to crypto.
