Calamos Bets Protected Bitcoin ETFs Can Survive Market Volatility

May 28, 2026 — Asset manager Calamos Investments reports its protected Bitcoin ETFs are attracting steady inflows while spot Bitcoin ETFs bleed over $1 billion in outflows. Matt Kaufman, head of ETFs at Calamos, said the firm saw roughly $10 million to $15 million in inflows over recent weeks as advisors seek Bitcoin exposure with built-in downside protection.

Calamos offers three versions of its protected Bitcoin ETFs, including products with full downside protection and others that accept 10% or 20% downside risk. The firm structures these products using Treasuries and options tied to Bitcoin-linked indexes.

“You can get upside of Bitcoin with no downside risk,” Kaufman said, joining CoinDesk’s Jennifer Sanasie on Public Keys.

The mechanics work through a careful allocation strategy. Calamos allocates roughly 90% of assets into Treasuries to build the downside protection layer. The remaining budget purchases Bitcoin-linked call spreads through FLEX options. The firm created its own Bitcoin-linked index and listed FLEX options tied to that index after spot Bitcoin ETF options became available.

The products come in quarterly structures and laddered versions designed specifically for model portfolios. Kaufman noted that advisors are increasingly looking for Bitcoin exposure that reduces volatility and downside risk.

Market Context & Reaction

The broader crypto ETF market is seeing significant rotation, with over $1 billion exiting spot Bitcoin ETFs last week. Even as capital flows into HYPE, SOL, and XRP products, Calamos positions its protected ETFs as alternatives to traditional portfolio allocations.

Kaufman said some investors are moving from cash-like products into fully protected Bitcoin ETFs tied to Bitcoin performance but without downside exposure. Wealth managers are becoming more sophisticated in how they evaluate crypto exposure, shifting from questions about whether Bitcoin belongs in portfolios to how to improve risk-adjusted returns.

“You don’t just have to sit in the spot vehicle anymore and ride out those waves,” Kaufman said, highlighting the evolution beyond simple spot exposure.

Background & Historical Context

The crypto ETF market is dividing into three distinct strategy categories: protection, income, and growth. Calamos previously launched auto-callable income ETFs and is exploring additional crypto-related strategies. Other ETF issuers have focused on generating yield from Bitcoin volatility through options-based products.

Kaufman said advisors previously focused entirely on whether Bitcoin belonged in portfolios at all. Now, advisors are asking how to improve risk-adjusted returns and portfolio construction using crypto exposure. Calamos positions its products as alternatives to broad equities, bonds, and cash allocations.

The development of Bitcoin-linked FLEX options followed the launch of spot Bitcoin ETF options, enabling new structured product designs.

What This Means

Calamos expects Bitcoin volatility to remain a defining feature of the asset. Kaufman said he expects Bitcoin to revisit previous highs despite recent market turbulence.

He argued Bitcoin’s volatility profile creates opportunities for structured products and options-based strategies. “I think we’re going higher,” Kaufman said.

For investors, these products offer a way to gain Bitcoin exposure without the full downside risk that comes with spot holdings. Advisors can now offer clients Bitcoin upside with varying levels of protection, from full protection to accepting limited downside risk.

This evolving product landscape suggests crypto investing is maturing beyond simple buy-and-hold strategies, with structured products designed for specific risk tolerances and portfolio construction needs.
