Great post! Does Poly have Brent/WTI spread market? Didn't see one on search.

Polymarket are WTI maximalists unfortunately

Fascinating mismatch between Polymarket odds and Brent‑WTI futures. If reopening probability keeps falling, does the spread reprice quickly, or are energy traders discounting prediction markets altogether?

The short answer - it depends as year-end is a couple of months away and anything can happen. And no free lunch can exist for a long time (edge will decay) in these very efficient markets unless you express a very strong trading view from your insights.

Energy traders at firms (e.g; hedge funds, prop firms) do develop comprehensive models of their own to model these spreads. Of course, if there is a way to quantify these market events (where prediction market comes in) + finding correlation signals, they will surely use it to find alpha. Moreover, they have access to paid data (which can be expensive to obtain for retail folks). Hope that helps :)

That makes sense — edge decays fast in liquid markets.

What’s interesting is whether prediction markets become an input into those institutional models over time, or remain more of a retail sentiment proxy.

Do you see serious desks actively incorporating Polymarket probabilities yet, or still mostly watching physical flows and paid data?

Seems like an overly simplistic analysis. As a primarily domestic index, WTI should be more heavily impacted by increases in electricity demand for data centers. That (among plenty of other things) could easily account for an extra few dollars on the spread
