Together, before fees—needs both histories

Funding pays, the price is against you. Polymarket Perps is 0.060% cheaper against Kalshi than usual: you would sell low and buy high (spread −0.060% now, against zero (this spread has no 7-day history yet)). If the spread goes back, that is −$6 on $10k: about 2.0 days of funding at the current rate (+$3 a day). Mind the row above: over the last 7 days funding on this pair cost −0.161%, so the current rate has only just turned in your favour.
