The trending list in Robinhood Wallet shows a market cap beside each coin. It is the largest number on the row and the least useful one for judging what a position is worth. The number that answers that question is pool depth, and you have to go looking for it.
What market cap is
Market cap is the coin’s last price multiplied by its supply. Nobody paid that amount. It is the price of one small trade applied to every token in existence, including the ones that have never changed hands. Float versus market cap covers why the supply side of that sum is itself a choice.
What pool depth is
Pool depth is the money sitting in the pool the coin trades against. A new coin on Robinhood Chain has no order book and no firm quoting it. There is a pool, and the pool is the only buyer when you sell. Depth is the size of that buyer.
Depth is also a different thing from volume. Volume is how much changed hands over a period. Depth is how much is there now. Pool depth is not volume sets out the difference.
The gap on a real list
On 4 October 2026 the top entry on the trending list had a market cap under $200,000. Its pool held about $23,000. The headline figure was several times the money that could be taken out.
That gap is normal for a young coin. A market cap can grow on a handful of small buys, because each buy moves the price and the price is then multiplied across the whole supply. Depth only grows when someone adds money to the pool.
What the gap tells you
Put the two numbers side by side. When depth is a small fraction of market cap, the market cap is a claim that cannot be tested. Holders who together own most of the supply could not sell a meaningful share of it near the shown price. The first sellers get the pool’s money. The later ones get what is left.
When depth is a larger share of market cap the price has more behind it. That is still no promise. Depth can be withdrawn by whoever supplied it, as liquidity added versus pulled explains.
What it means for one position
The comparison that matters is your own size against the depth, with market cap left out of it. A position that is small against the pool can be closed near the shown price. A position that is a visible share of the pool sets its own exit price, and that price is lower.
The value an app shows for a holding is price times balance. That is the same arithmetic as market cap, and it has the same flaw. It assumes the last price is available for the whole amount.
Where NoVo shows it
The Crypto Market Map runs the Robinhood Chain trending list across the top of the page. Open a coin from the strip and pool depth sits beside the market cap, with turnover and the split of buying and selling wallets. It is a readout of what is in the pool now. It says nothing about where the price goes.
