Nodal Exchange

The Kansas City Board of Trade (KCBT) was a commodities futures exchange established in Kansas City, Missouri in 1856. It served as the world's primary marketplace for Hard Red Winter Wheat futures and options, a critical benchmark for the global wheat market. CME Group acquired the KCBT in 2012, integrating its flagship wheat contracts into the CME Globex electronic trading platform.

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.

Flett Exchange was a New Jersey-based electronic exchange for environmental commodity credits, established around 2004. Flett specialised in US environmental market instruments including NOx (nitrogen oxide) allowances under the EPA SIP Call, SO2 (sulphur dioxide) allowances under the Acid Rain Program, Regional Greenhouse Gas Initiative (RGGI) carbon allowances, and Renewable Energy Certificates (RECs). The exchange served power generators, utilities, and compliance buyers navigating the complex US state and federal cap-and-trade regulatory frameworks for air emissions.

The Chicago Climate Exchange (CCX) was North America's first and only voluntary, legally binding greenhouse gas emission reduction and trading system. Founded in 2003 by economist Richard Sandor, CCX allowed member companies to make binding commitments to reduce carbon emissions and trade Carbon Financial Instruments (CFIs). Acquired by ICE (Intercontinental Exchange) in 2010, CCX ceased operations the same year after voluntary carbon credit prices collapsed following the failure of US cap-and-trade legislation.
