Bakkt, a crypto platform introduced amid great fanfare in 2018 by the owner of the New York Stock Exchange, warned Wednesday that it might not be able to stay in business.

"We might not be able to continue as a going concern," the company said in a document filed with the U.S. Securities and Exchange Commission. "We do not believe that our cash and restricted cash are sufficient to fund our operations for the 12 months following the date of" the filing.

Bakkt is seeking to sell up to $150 million of securities, according to a Bakkt spokesperson, which could ease this problem.

The company was set up by Intercontinental Exchange, which owns large derivatives exchanges plus the NYSE, with the initial goal of helping Starbucks customers buy coffee with bitcoin (BTC). Future U.S. Senator Kelly Loeffler was its first CEO. It finally introduced a digital wallet in 2021, but that was discontinued last year. Bakkt is now focused on crypto custody and trading services.

Overall efforts to use bitcoin, the asset, and Bitcoin, the blockchain, for payments have seen little success, though the Lightning Network, a layer-2 blockchain where Bitcoin transactions can be offloaded for more-efficient processing, aims to turn that into reality.

Bakkt went public in 2021. Its stock trade closed Wednesday at $1.45, down from more than $40 in 2021.
