Calamos uses Cboe Bitcoin options to create defined outcome ETFs with built-in downside protection

Calamos Investments has launched a suite of “Protected Bitcoin” defined‑outcome ETFs that use Cboe-listed Bitcoin ETF index options to cap downside and limit upside over one‑year outcome periods. The lineup offers 100%, 90% and 80% protection tiers (e.g., CBXJ targets 90% protection and had an NAV of $21.54) and supports a laddered, quarterly structure to reduce entry‑timing risk. The products are aimed at financial advisors and RIAs, offering ETF wrappers that solve custody and compliance hurdles and make Bitcoin allocations feasible within conventional risk frameworks. Market impact: if advisor uptake mirrors equity buffer ETF adoption, flows into the category could be meaningful; however, performance delivery depends on liquidity and pricing in the underlying CBTC and MBTX options market, which is still maturing and could widen costs or affect realized outcomes.
