Coinbase-linked stock tokens have generated more than $1 billion in cumulative trading volume, but pre-market testing on September 23 showed that historical volume and available liquidity are not interchangeable. Before U.S. equities opened, all 10 Coinbase stock tokens on Base showed indicative buy and sell quotes for orders of about $100,000. Those quotes were router estimates at a specific point in time, not completed trades. They also did not show how much inventory the market could absorb, or how far prices might fall, if several holders sold at once.
$100,000 quotes showed limited slippage, not market depth
During the test, KyberSwap provided buy and sell routes for all 10 tokens. Based on KyberSwap's own dollar valuations, the proceeds from selling approximately $100,000 of each token were 0.06% to 0.71% below the estimated value of the assets being sold. The gap was 0.06% for AAPLc, 0.10% for GOOGLc and 0.13% for both NVDAc and METAc. MSTRc and SNDKc showed the widest sell-side gaps, at 0.71% and 0.61%, respectively.
The corresponding buy quotes showed gaps ranging from 0.09% to 0.76%. MSTRc had a 0.76% gap, followed by SNDKc at 0.69%, TSLAc at 0.51% and AAPLc at 0.10%. These figures describe KyberSwap's estimate for a single order at one point in time. They do not represent the spread between the tokens and the corresponding stocks on the New York Stock Exchange or Nasdaq, and they do not mean that a trade was executed. Some routes use multiple liquidity sources, so the quoted amount may exceed the capacity of a single Aerodrome pool.
When the order size was reduced to approximately $10,000, the sell-side gap narrowed to about 0.01% to 0.12%. As the order size increased to $100,000, slippage widened for most of the tokens. No trades were submitted during the test, and network fees were excluded. The KyberSwap interface also requires a separate step to generate a transaction, making the results closer to an execution check than a record of completed transactions.
Aerodrome pools held a combined $12.97 million
At the time of the test, the 10 relevant Aerodrome stock-token/USDC pools displayed combined balances of approximately $12.97 million. Individual pool sizes ranged from about $818,700 for MSFTc to roughly $2.11 million for NVDAc. The other pools included approximately $1.50 million for AAPLc, $1.66 million for GOOGLc, $2.10 million for METAc, $1.03 million for AMZNc, $862,000 for TSLAc, $940,300 for MSTRc, $952,600 for SNDKc and $1 million for SPCXc.
Those figures combine the two assets held in each pool: the stock token and USDC. They do not show how much capital is available to absorb sell orders within a particular price range, nor how much liquidity would remain after the price moved lower. As a result, the $12.97 million aggregate balance cannot be treated as the amount immediately available for sellers seeking to exit.
Dromos Kitchen's stock-token data dashboard showed on September 23 that the tokens had recorded approximately $1.02 billion in cumulative trading volume and had a combined token value of about $19.82 million. The community-maintained dashboard cautioned that its data might be incomplete. Cumulative volume is the sum of past transactions; it does not mean that $1 billion of buy-side demand is currently waiting to absorb a large sell order.
AERO incentives can change liquidity-provider behavior
Aerodrome uses AERO emissions to incentivize providers who stake liquidity positions. Under its rules, providers who stake their pool positions to receive AERO emissions no longer receive trading fees directly. Those fees instead go to the voters who determine the distribution of emissions. Pool fee income and AERO incentives therefore represent separate sources of value, while displayed balances can also change as the incentive structure shifts.
When the tokens launched in August, Beefy said Coinbase was providing USDC incentives through Merkl on a two-week cycle. Beefy was adding further incentives on top of Aerodrome emissions. These arrangements show how liquidity was attracted during the launch phase, but they do not establish the current yield of each stock-token pool. If incentives are reduced, voting allocations change or liquidity providers move funds elsewhere, past trading volume will not prevent immediately available liquidity from falling.
On-chain trading can continue while U.S. markets are closed
Base says the Coinbase stock tokens are backed by the relevant shares held by regulated custodians and are available only to eligible users in jurisdictions outside the United States. Base's developer documentation says secondary-market trading can be enabled subject to address-control requirements, while primary minting and redemption of the underlying shares remain limited to authorized participants.
That structure allows token trading to continue beyond regular U.S. equity-market hours. Base documentation says Chainlink's stock-price data will hold the last observed value while U.S. markets are closed, even though on-chain trading may continue. A holder selling after hours is therefore trading against a token market that can keep moving while the reference price for the underlying stock remains at its last level. Because the creation and redemption channels are controlled by authorized participants, ordinary secondary-market liquidity providers must perform the immediate price-discovery function.
The September 23 test showed that $100,000 orders could still receive indicative prices even though some pools displayed relatively modest balances. But changes in AERO voting, liquidity-provider capital or after-hours news about the underlying stocks could quickly alter executable quotes while the underlying price feed remains unchanged. For holders, cumulative volume, total pool balances and the quote for a single order remain separate measures of market liquidity.
