Chicago Climate Exchange

The Chicago Board of Trade (CBOT) is one of the world's oldest futures and options exchanges, established in 1848 in Chicago, Illinois. Originally founded to address supply and demand challenges in the grain industry, CBOT grew to offer contracts across agricultural commodities, CBOT U.S. Treasury bonds, equity indexes, and metals. CME Group merged with CBOT in 2007, making it one of four Designated Contract Markets within the CME Group family.

HedgeStreet Exchange was a CFTC-regulated US derivatives exchange founded in 2004, offering small-denomination binary contracts (starting at $10) on economic events including crude oil prices, gold, natural gas, and macroeconomic indicators. Designed to democratise derivatives access for retail traders, HedgeStreet was one of the first exchanges to offer CFTC-regulated retail binary options on commodity prices. In 2008, the exchange was acquired and eventually rebranded as Cantor Exchange (part of Cantor Fitzgerald), which subsequently ceased operations.

MATba Rofex is Argentina's leading derivatives exchange, formed in 2019 through the merger of the Buenos Aires Cereals Market (MATba, founded 1907) and the Rosario Futures Exchange (Rofex, founded 1909). As Argentina's primary exchange for agricultural commodity futures, it trades soybeans, corn, wheat, sunflower seed, and soybean products alongside financial futures including US dollar, sovereign bonds, and equity index contracts. MATba Rofex is critical for Argentine agribusiness hedging, as Argentina is one of the world's top soybean exporters.

Launched in the late 1990s during the initial wave of online energy trading, the platform ceased operations in the early 2000s following the collapse of energy trading markets in the wake of the Enron scandal.
