the charts below follow

Funding, last 4 days (all we have)—no history yet

Price spread, last 7 days—no price history on both exchanges yet

Together, before fees—needs both histories

Both sides work for this trade now. Funding pays +$1 a day on $10k at the current rate, and MEXC is 9.508% dearer against Injective than usual: you sell high and buy low: +$951 more if the spread goes back to zero (this spread has no 7-day history yet). The two prices were read 70 seconds apart, so part of this spread may be the market moving, not a spread.
