Calamos is seeing demand for Bitcoin products that add downside protection while still offering upside tied to Bitcoin. The firm says advisors are increasingly comparing crypto exposures the same way they evaluate portfolio construction, risk, and return.
Calamos is making Bitcoin funds that try to protect people if the price falls. It is like buying a ticket for a roller coaster that has a safety seat attached.
Instead of only owning Bitcoin directly, these funds mix safe government bonds with betting tools tied to Bitcoin. That lets investors keep some upside while limiting how much they can lose.
The company says more money is going into these safer Bitcoin funds because some investors want Bitcoin exposure without the big stomach-drop. It thinks Bitcoin’s wild price swings will keep creating demand for products like this.
Analysis
What Calamos is seeing
Calamos says its protected Bitcoin ETFs are attracting money even as spot Bitcoin ETFs saw more than $1 billion in outflows last week. Matt Kaufman, the firm’s head of ETFs, said inflows into its products have been around $10 million to $15 million over the past several weeks.
How the products are built
The firm offers three protected Bitcoin ETF versions, including one with full downside protection and others with 10% or 20% downside risk. Kaufman said the structure uses roughly 90% of assets in Treasuries to provide protection, while the remaining capital buys Bitcoin-linked call spreads through FLEX options. Calamos also built its own Bitcoin-linked index and listed FLEX options tied to that index after spot Bitcoin ETF options launched.
What advisors want now
Kaufman said wealth managers have become more sophisticated. Earlier, he said, the main question was whether Bitcoin belonged in a portfolio at all. Now the discussion is about how crypto exposure affects risk-adjusted returns and overall portfolio design.
Calamos is positioning these ETFs as alternatives to cash, bonds, and equities for investors who want Bitcoin exposure without taking the full downside. The firm also sees the broader crypto ETF market splitting into three buckets: protection, income, and growth. Kaufman said Calamos has already launched auto-callable income ETFs and is looking at more crypto-related strategies. He also said Bitcoin volatility will remain central to the asset and argued that the swings create room for structured products to grow.
