Calamos Investments has rolled out a lineup of “Protected Bitcoin” ETFs that use Cboe-listed options to give investors exposure to Bitcoin’s upside while capping their potential losses at predetermined levels. Think of it as Bitcoin with a seatbelt: you still get to ride, but the airbags are included.
The suite offers three distinct protection tiers, covering 100%, 90%, and 80% of downside risk over a one-year outcome period. Each fund aims to track Bitcoin’s price performance up to a cap, meaning investors trade unlimited upside for the comfort of knowing exactly how much they can lose.
How the structured Bitcoin ETFs actually work
The mechanics borrow heavily from the world of equity buffer ETFs, which have been a growing favorite among financial advisors who want market exposure without the full stomach-churning drawdowns. In English: Calamos is taking a playbook that already works for stocks and applying it to the most volatile major asset in finance.
Each ETF uses Cboe Bitcoin ETF index options, specifically the CBTC and MBTX contracts, to construct its structured outcomes. These options are tied to Bitcoin’s price movements, and by layering them strategically, Calamos can define both the floor (how much you can lose) and the ceiling (how much you can gain) over a set period.
