=Together, before fees—needs both histories
Both sides work against this trade now: funding costs −$8 a day on $10k at the current rate, and Injective is 1.284% cheaper against Polymarket Perps than usual: you would sell low and buy high (−$128 if the spread goes back to zero (this spread has no 7-day history yet)). Swap the legs. The two prices were read 51 seconds apart, so part of this spread may be the market moving, not a spread.
The current funding rate is far above what this pair has been paying: over the last 7 days it paid -0.142% in total (about -7.4% a year). A funding rate is set anew for every payment; at this rate the next one is about −$0.34 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
