How much BTC is resting in the perpetual-futures order books of Binance and Bybit, side by side: bid and ask USD within ±0.1%, 0.5%, 1% and 2% of mid, the bid/ask imbalance, and what a $100k and a $1M market order would cost in basis points. Live snapshots from the exchanges' public order-book APIs, refreshed every couple of minutes.
BTC is #1 by open interest on Binance ($8.02B) and #1 on Bybit ($2.36B). Within ±0.1% of mid, Bybit holds $34.97M of resting BTC bids and asks against ≥ $29.28M on Binance.

How to read it. Each band row shows the resting bid and ask USD within that distance of the mid price. ≥ $X (truncated) means the exchange's 500 returned levels end inside the band, so the real figure is at least that. Imbalance is (bids − asks) / (bids + asks) within ±1%, or within the range the snapshot reaches on both sides when that is less. Market order rows give the average fill versus mid, in basis points, half-spread included and fees excluded.

BTC order book FAQ
How deep is the BTC order book?
The tables show the USD value of resting BTC bids and asks within ±0.1%, 0.5%, 1% and 2% of the mid price on Binance and Bybit, from a live snapshot of each exchange's book. Values marked ≥ (truncated) are lower bounds: the exchange returned its 500 best levels per side and they end inside that band.
How much does a $100k or $1M BTC market order move the price?
We walk the ask side (for a buy) or the bid side (for a sell) from the best price until the order is filled, and compare the average fill with the mid price, in basis points (1 bps = 0.01%). Half the spread is included; fees, hidden orders and the book moving while you trade are not.
What does bid/ask imbalance mean?
(bids - asks) / (bids + asks) within ±1% of mid: positive means more resting buy orders, negative more sell orders. Resting orders can be pulled at any moment, so it is a snapshot of intent, not a signal on its own. Nothing here is financial advice.
