Shipping & chokepoint markets

Throughput markets on the world's busiest maritime chokepoints.

CLARA

Shipping and chokepoint markets let you trade on throughput and vessel arrivals across the world's busiest maritime chokepoints — passages such as the Suez and Panama canals and the Strait of Hormuz. Each market poses a clear yes/no question, from whether a vessel reaches a port or chokepoint on schedule to how much traffic moves through it over a set window. Prices move like live probabilities as voyages progress, so a contract can reprice sharply when congestion builds or a passage slows. Every market's terms are fixed when it opens, and it settles automatically afterward from official arrival and throughput data. Trading carries zero fees. Maritime markets round out GADUIN's supply-chain disruption category, alongside flight and rail contracts.

About shipping & chokepoint markets

What these markets are

Shipping markets track vessels and throughput at the world’s critical maritime chokepoints — the Suez and Panama canals, the Strait of Hormuz, Bab-el-Mandeb. Some contracts ask whether a specific voyage reaches port on time; others track how much traffic clears a chokepoint over a window. They open ahead of the estimated arrival and close when it is due. When a chokepoint clogs or port congestion builds at the destination, throughput falls and the delay flows straight down the supply chain — into retailer stockouts, idled factories, and higher freight costs.

How to read the price

A price is the probability the market assigns to an outcome. An "on time arrival" contract at 70% costs about $0.70 and pays $1 if the vessel reaches port within the window. Because voyages run for days and can queue for canal transit or divert around trouble, these prices tend to swing more than a single flight or train.

How settlement works

Ships settle on official maritime and port records: the vessel's recorded arrival, or the measured throughput at the chokepoint, against the value fixed when the market opened. Settlement is automatic, with no manual call.

Worked example

A container ship bound for Rotterdam via Suez opens at "on time" 65%. Congestion builds at the canal and tracking shows the vessel anchored in the waiting queue; "on time" slides to 30%. It arrives two days behind its locked ETA — the on-time contract settles $0 and the delayed side is paid.
