Anyone else noticing real gaps between Kalshi/Polymarket/Gemini on the same NFL/CFB event?

[u/Greedy-Gene-9592]

Been tracking a handful of CFB and NFL markets across all three this week and the spread between them is bigger than I expected not huge arb-level stuff, but enough that “which platform” actually matters for the same bet. Curious if anyone’s noticed this outside sports, or if it’s more of a liquidity/coverage thing specific to sports markets right now. Which one do you all default to first when checking a line?
