Calamos CAIE ETF hits $1B in assets with weekly inflows since launch

An ETF that barely existed a year ago just crossed $1 billion in assets under management. The Calamos Autocallable Income ETF, trading under the ticker CAIE, has pulled in new money every single week since its June 25, 2025 launch.

As of June 1, 2026, CAIE’s total net assets stood at $968.7 million.

A consistent money magnet

Over the most recent five-day period, CAIE attracted $25.58 million in net inflows. Over the past month, that figure climbed to $83.43 million.

The growth trajectory has been steep. CAIE crossed the $500 million AUM mark by late December 2025, roughly six months after launch. It then doubled that in about five more months.

The fund was named to the 2026 ETF Watch List by CFRA, the independent research firm, which recognized its innovative approach.

What CAIE actually does

CAIE is an actively managed ETF that provides exposure to autocallable yield notes through total return swaps on a US large-cap laddered portfolio.

The distribution rate sits around 14%. The strategy aims to deliver high monthly income while mitigating downside risk. Calamos Investments has positioned it as a democratization play, as strategies like this used to be locked behind minimum investment thresholds and accreditation requirements that kept retail investors on the outside looking in.
