SPX Funding Rate History — Settled Payments by Exchange

What SPX (SPX6900) actually paid over the last 30 days: 6,300 settlements across 20 venues, broken down venue by venue. These are settled payments — the amount an exchange actually charged or credited each funding interval — not the rate currently quoted for the next payment. Aftermath paid the most over the window at +6.9491% of position size.

A funding rate quoted right now is a forecast of the next payment; what a position actually earned is the sum of payments that already settled. Two venues can quote a similar rate and still pay very differently over a month, because they settle on different schedules and compute the rate from their own order book rather than a shared index. The rate was positive in 89% of the 6,300 settlements recorded here, meaning longs paid shorts that often.

Over the window, settled totals ranged from +6.9491% on Aftermath to -4.3692% on Crypto.com — the gap between them is what a delta-neutral position collecting on both legs would have captured before fees and slippage.
