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.

The Brazilian Mercantile and Futures Exchange (BM&F) was one of the world's largest derivatives exchanges, founded in São Paulo in 1983.

In 2017, it merged again with CETIP to create B3 (Brasil, Bolsa, Balcão) — now Latin America's largest financial exchange group by market capitalisation. B3 continues to operate commodity derivatives including sugar, arabica coffee, live cattle, ethanol, and gold contracts.

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).

MATba Rofex is critical for Argentine agribusiness hedging, as Argentina is one of the world's top soybean exporters.

The Memphis Cotton Exchange, founded in 1873 in Memphis, Tennessee, was a historic spot market for cotton pricing, grading, and trading in the American South. As one of the world's largest cotton-handling cities, Memphis became a natural hub for cotton commerce. The Exchange provided standardised grading and price reporting services for the US cotton industry for over a century, though trading activity and formal exchange functions have significantly diminished as futures markets and ICE took over price-discovery roles.
