I haven't found any other collaborating articles, but this one says that it was an empty gas carrier. > The prospects of a growing wait reportedly prompted one company to bid a record $4 million for one of the open slots bringing their anticipated total transit costs to $4.5 million and still they have to wait another week to get their empty gas carrier on its way. https://maritime-executive.com/article/panama-canal-auction-sets-record-4m-for-slot-as-congestion-grows https://maritime-executive.com/article/panama-canal-auction-... Later in the article, it says that they might give up their bid, which sounds to me like they had contracts that needed fulfillment with expensive penalties. Probably made the bid to hedge their bets, and are working right now to renegotiate penalties to account for unforeseen circumstances.
