Coinbase's stock tokens have reportedly seen over $1 billion in trading volume, giving the impression of market activity. However, potential sellers may face uncertainty regarding how much of the market can absorb their sales and at what price, especially outside of US equity hours.

On September 23, a premarket assessment revealed indicative buy and sell routes for approximately $100,000 of each of Coinbase's ten stock tokens on the Base platform. Estimates indicated that selling these tokens would yield proceeds ranging from 0.06% to 0.71% below KyberSwap's own dollar valuation of the tokens. Notably, these price routes only reflect the valuation at a single point in time and do not account for capacity during a simultaneous sell-off.

During this assessment, the ten main Aerodrome stock/$USDC pools had combined displayed balances of about $12.97 million, with individual pools varying significantly in size. For instance, the Microsoft stock token held roughly $818,700, while the NVIDIA stock token had about $2.11 million. These pool balances include both the stock tokens and $USDC, leaving the available liquidity for sales within specific price ranges unclear.

According to Dromos Kitchen's dashboard on September 23, cumulative trading volume stood at around $1.02 billion, with a total tokenized value of $19.82 million. This data, which is community-sourced, warns of potential incompleteness. It emphasizes that accumulated turnover does not indicate a fresh pool of buyers ready for large sell orders.

Details regarding the sell quotes reveal a discrepancy between Aerodrome pool balances and KyberSwap's estimated selling routes. For example, while the NVIDIA stock token had a pool balance of $2.11 million, the sell quote gap for a $100,000 order was 0.13%, indicating a decline in value relative to the underlying input.

A breakdown of the other stock tokens shows various buy and sell quote gaps, with overall sell-side gaps widening with larger orders. These gaps reflect how much the router's estimated output dollar value fell below its own dollar valuation.

Market liquidity also depends on the incentives offered to liquidity providers. Under Aerodrome's rules, these providers who stake their positions sacrifice direct swap-fee rewards to voters who direct emissions. While Coinbase initially provided $USDC incentives at the launch of the platform, the current returns for liquidity pools remain unverified and subject to change if incentive structures or votes shift.

Coinbase's tokens are reportedly backed by underlying shares held in regulated custody and are available only to eligible jurisdictions outside the United States. The developer documentation maintains that while secondary token trading is permissionless, minting and redeeming the underlying shares remain restricted to authorized participants.

These tokens can potentially change hands even when the US stock market is closed. The Chainlink equity feed holds its last value outside market hours, yet on-chain token trading may continue. This situation could complicate sales made after hours, wherein the live token market may not accurately reflect the most current equity reference. Therefore, secondary-market liquidity providers are responsible for setting prices during these transactions.
