C Basis: Perp vs Spot Premium
Live C basis: the C perpetual futures price against the same exchange's spot price, perp / spot - 1. A positive basis is a futures premium, a negative one a discount. One row per venue pair on Binance and Bybit above the liquidity filter, then the recorded basis history for 24 hours, 7 days and all time.
No C perp/spot pair on Binance or Bybit currently meets the comparable-pair and minimum-liquidity rules ($500K open interest, $1.00M 24h volume on the perp leg), so there is no live basis to show (Aster CUSDT: no same-venue spot market; Binance CUSDT: below the liquidity floor; Bitget CUSDT: no same-venue spot market; Bybit CUSDT: no same-venue spot market; Gate C_USDT: no same-venue spot market; KuCoin CUSDTM: no same-venue spot market; MEXC C_USDT: no same-venue spot market).

Not recorded Chart: TradingView Lightweight Charts™
How to read it. Basis is perp / spot - 1 on the same exchange, shown live and un-annualised. Green is a premium (perp above spot), red a discount. Pairs need the same venue and quote currency, and the perp leg needs at least $500K open interest and $1.00M 24h volume. Compare every coin on the basis screener, and see C funding rates, which move for related reasons. The basis guide explains the per-exchange history and the 7-day average.
C basis FAQ
What is C basis?
C's basis is the gap between its perpetual futures price and its spot price on the same exchange, as a percentage: perp / spot - 1. A positive basis is a futures premium (the perp trades above spot), a negative one a discount. It tends to move with funding rates, because funding exists to pull the perp back to spot.
Why can the chart differ from the table?
The table is the live basis of each pair that clears the minimum-liquidity filter ($500K perp open interest, $1.00M 24h volume), from the latest trade price. The chart and the 7-day average are recorded history: every same-venue, same-quote pair of the coin, OI-weighted, from the perp mark price in 5-minute and hourly snapshots.
Why is Hyperliquid not in the table?
This site tracks no Hyperliquid spot markets, so a Hyperliquid perp has no same-venue spot price to compare against. Basis here covers Binance and Bybit only.
Is a high C futures premium a signal?
Not by itself. A rich premium often means leveraged longs are paying up, which also shows in funding; a stretched premium or discount can unwind quickly. Nothing here is financial advice.
