Associated Press cites a service called Windward for their shipping data. I'm completely ignorant on the subject, but might that be of help for you? https://apnews.com/live/iran-war-israel-trump-04-08-2026#000... (second paragraph).
Your site is very cool. Will test further.
That’s actually a great find, this page[1] from them I found seems to have more recent data than I’ve otherwise been able to find. I’ll reach out to them to see if they can provide some data to power my site as I don’t like the current setup of old data and prediction market odds. Thanks!
