The Calamos Autocallable Income ETF, trading under the ticker CAIE, has crossed $1 billion in assets under management. The fund has recorded positive weekly inflows every single week since it launched on June 25, 2025.
CAIE surpassed $500 million in assets just six months after launch. As of June 1, 2026, the ETF’s assets under management stood at $968.7 million, with a market price of $27.54 and a net asset value of $27.50. Inception-to-date net flows exceeded $933 million at that point, meaning the final push to $1 billion came shortly after.
The most recent monthly inflow figure was $83.43 million. The distribution rate was 14.30% as of April 30, 2026. Monthly payouts have landed at approximately $0.32 per share.
What CAIE actually does
CAIE uses total return swaps to gain exposure to a laddered portfolio of more than 52 autocallable yield notes. These are tied to the MerQube US Large Cap Vol Advantage Autocallable Index. The laddering means the notes mature at staggered intervals, smoothing out the risk that any single note gets called or breached at an inopportune time.
The ETF’s holdings include collateral ETFs, US Treasuries, and the total return swaps linked to that autocallable index. It’s actively managed by Calamos Investments. The expense ratio sits between 0.74% and 0.86%.
Why this matters for income-focused portfolios
CAIE was first to market wrapping autocallable yield notes in an ETF structure, making a strategy previously available only to institutional investors and high-net-worth advisory platforms accessible to anyone with a brokerage account, with daily liquidity and transparent pricing.
The 14.30% distribution rate deserves scrutiny. Autocallable structures carry tail risk that isn’t always visible in normal market conditions. If the underlying index experiences a sharp decline that breaches the barrier levels on multiple notes simultaneously, the fund could face significant losses. The high distribution rate partially reflects the option premium embedded in the autocallable structure, meaning investors are being paid for selling insurance against a market downturn.
For investors already in the fund or considering an allocation, the key metric to monitor is the barrier levels on the underlying autocallable notes and how much room exists between current index levels and those barriers.
