BTC: Captured Mempool Output Value at 0–<1 sat/vB in USD

Bitcoin Captured Mempool Output Value at 0–<1 sat/vB in USD was $6,253,596.83 on 5 Nov 2026 (latest daily value).

The dollar value of everything unconfirmed Bitcoin transactions paying under 1 sat/vB are sending, in our node's mempool, its queue of transactions waiting for a block.

Why use it. It shows how much money is waiting to move at the cheapest transactions, which confirm only when blocks have room to spare. How to read it. Each point is the last reading of the queue in the 10 minutes, hour or day, not an average. The value counts every output, including change and chains of transfers, so it is not the amount actually paid between people. It is one node's view of the queue, not the whole network's, and not a forecast of confirmation times.

Calculation. Exact definition: The USD value of all decoded outputs of transactions paying 0 to under 1 sat/vB in the captured local Bitcoin Core mempool. Output value counts every decoded output, including change, unspendable outputs and repeated transfers within transaction chains; it is not unique supply, economic payment volume or miner income. Each UTC 10-minute, hour or day point uses its last actual capture; band membership stays in sat/vB, lower-inclusive and upper-exclusive. Missing or unpriced captures remain gaps, while a proved empty capture with an eligible quote is zero. This is one local node's prospective snapshot, not a global mempool, execution price or confirmation-time forecast. Group each captured transaction by its Core base fee divided by Core policy virtual size, sum the exact output satoshis in this band, and multiply by the originally admitted prospective BTC/USD quote divided by 100,000,000, keeping reduced rational values until decimal rounding. A value needs the original complete membership and an independently decoded population. The original capture and received quote are reused, never a later quote, and monetary freshness uses the earlier of their clocks.
