Funding between these two exchanges is close to zero, so right now this pair is about the price spread alone: Injective is 0.698% cheaper against Extended than usual: you would sell low and buy high, −$70 on $10k if it goes back to zero (this spread has no 7-day history yet). The two prices were read 80 seconds apart, so part of this spread may be the market moving, not a spread.
