Cryptoexchange Coinbase's pre-IPO shares have continued to rise on private markets following the release of its S-1 regulatory filing on Thursday. The shares, which trade under the ticker CBSE, were up 2.41% at the time of writing-trading at $395 on crypto derivatives trading platform FTX. About a month ago, a share was worth just $272, so the price has risen 45% in the past month. But just $71,628-worth of CBSE has been traded in the past 24 hours, according to FTX data. FTX, the crypto trading platform run by billionaire Sam Bankman-Fried, allows people to invest in Coinbase before it goes public on the Nasdaq. To do this, it's issued a pre-listing futures contract market. Coinbase shares will debut on the Nasdaq in the coming weeks through direct listing. Right now, there is also a secondary market for Coinbase stock on the Nasdaq Private Market. This means those with vested equity, such as Coinbase employees, can trade shares ahead of the public listing.
