Coinbase and Upbit Are Listing 2 New Altcoins Today

The leading US-based cryptocurrency exchange, Coinbase, and South Korea’s prominent exchange Upbit have announced the addition of new altcoins to their trading platforms. 

The listings include support for Flock (FLOCK) on both exchanges, with Coinbase also introducing SPX6900 (SPX). These moves have triggered significant price surges. Moreover, the former peaked at a new record high in early Asian trading hours today.

Coinbase and Upbit Announce New Altcoin Listings 

In an official X (formerly Twitter), Coinbase confirmed that it will list both altcoins. Trading is scheduled to begin on or after 9:00 AM Pacific Time (PT) on September 9. The rollout will only proceed once there is an adequate token supply.

“Coinbase will add support for SPX6900 (SPX) on the Ethereum network (ERC-20 Token) and Flock (FLOCK) on the Base network. Do not send these assets over other networks or your funds may be lost,” the announcement read.

Moreover, trading for the SPX-USD and FLOCK-USD pairs will be introduced in phases. The exchange also clarified that the availability of these assets may vary by region, as some jurisdictions will face restrictions.

Following the Coinbase announcement, SPX, a meme coin, experienced a modest price increase. The price rose from $1.33 to $1.41, marking a 6.02% gain. The pump was short-lived, and the token shed its gains to trade at $1.32, down 1.26% at press time.

Meanwhile, FLOCK saw a more pronounced uptick. The altcoin climbed from $0.26 to $0.30, a 15.38% rise, reflecting early market enthusiasm. These movements align with the so-called ‘Coinbase Effect,’ where listings on the platform often lead to immediate price boosts due to increased visibility and perceived legitimacy.

While Coinbase’s news prompted modest gains, Upbit’s decision to add FLOCK to its Korean Won (KRW) market triggered a far stronger reaction.

“Please make sure to check the correct network before making any deposits of digital assets. Deposits or withdrawals made through networks other than the ones indicated are not supported,” Upbit wrote.

Trading began at 12 PM Korean Standard Time (KST) and sent FLOCK soaring. The altcoin’s price surged from $0.31 to $0.99, a 219.35% increase, with the latter marking a new all-time high (ATH).

At the time of writing, the price adjusted to $0.50, marking an appreciation of 84.37%. In addition, FLOCK’s daily trading volume soared. It reached $197 million, a 2,051.30% increase from the previous day. 

Bithumb and Upbit accounted for most of this activity, with shares of 23.2% and 22.9%, respectively, highlighting the exchanges’ significant influence on the token’s liquidity. 

The back-to-back listings highlight how regional exchange support can magnify global market momentum. Coinbase’s brand power and Upbit’s dominance combined to propel FLOCK into the spotlight, with volatility and trading activity expected to remain elevated as liquidity deepens.
