On May 15th, Bloomberg ETF analyst Eric Balchunas wrote that asset management company Calamos has submitted an application for a Bitcoin "buffer" ETF. This ETF will seek to provide 100% downside protection for Bitcoin while capturing some upside using FLEX options. It is currently unclear whether the application is for spot or futures type.

Previously reported, on December 15th, 2023, Bloomberg ETF analyst James Seyffart wrote that First Trust submitted a Bitcoin "buffer" ETF application to the U.S. Securities and Exchange Commission (SEC). It is expected that other entrants in this field will use unique differentiation strategies to provide Bitcoin exposure in the coming weeks.
