MerQube partners with Kalshi to provide indices for perpetual futures. Related topics. MerQube has announced a partnership with Kalshi, a CFTC-regulated exchange, to provide three MerQube indices as the reference benchmarks for Kalshi's perpetual futures on US equities. Perpetual futures are derivatives that follow an index's price with no expiry date, so investors can go long or short and hold a position open until they choose to close it, without rolling it from one contract to the next. Periodic funding payments keep the contract price aligned with the underlying index. The partnership builds on Kalshi's October 6, 2026 launch of its US Large Cap perpetual futures, the first regulated perpetual futures on a US equity index, offering leveraged access to 500 of America's largest companies. The US Large Cap references the MerQube US Large Cap TR Index (MQ5CT), which tracks 500 of the largest US-listed and US-domiciled companies. Kalshi has since launched its US Tech 100 perpetual futures, linked to the MerQube US Technology TR Index (MQBUSTQT), which tracks 100 of the largest eligible tech companies. US Small Cap, is expected to follow shortly, linked to the MerQube US Small Cap TR Index (MQ2MT), which tracks 2,000 companies in the US small cap equity market. Together, the three indices enable Kalshi's customers to hold continuous, no-expiry positions in large-cap, technology and small-cap equity markets on a single regulated platform. MerQube calculates and administers each index, providing the transparent, rules-based, independently governed benchmarks regulated derivatives require. Commenting on the launch, Vinit Srivastava, MerQube CEO, says: "We are pleased to combine our expertise building indices for the derivatives market with Kalshi's drive to create entrepreneurial and groundbreaking products. The uptake of Kalshi's US Large Cap shows there is real demand for regulated exposure to US equities through perpetual futures. Extending MerQube and Kalshi's partnership to technology and small caps gives Kalshi a complete set of benchmarks, built on the calculation and governance standards that exchanges and their participants expect." Andy Ross, Head of Institutional at Kalshi, says: "Perpetual futures are changing the way assets are traded, and we believe their potential extends far beyond crypto. Through our partnership with MerQube, we're bringing that model to some of the most familiar exposures in financial markets, starting with broad US equities. US Large Cap demonstrates what becomes possible when you combine trusted benchmarks with a simpler, continuous futures structure in a regulated US market." * October 28, 2026 MerQube has announced a partnership with Kalshi, a CFTC-regulated exchange, to provide three MerQube indices as the reference benchmarks for... * October 28, 2026 WisdomTree and Return Stacked ETFs, whose ETFs stack alternative strategies on top of core stock or bond exposure, have announced... * October 28, 2026 TXSE Group, the parent company of the Texas Stock Exchange, has announced an equity investment from State Street, the world's... * October 21, 2026 Albemarle Street Partners will rebrand on 1 February 2027, becoming WisdomTree Portfolio Solutions, following WisdomTree's acquisition of Atlantic House in...

Calamos extends autocallable leadership through CAYN - world's first indexed Least-Of Autocallable Income ETF. by Calamos Investments October 19, 2026 * Calamos continues to innovate in autocallable ETFs with an indexed approach to the popular "least-of" (also known as "worst-of") autocallable income structure - expanding upon the broadest line of autocallable ETFs in the world. * CAYN links income payments and principal repayment to the weakest performer among SPY, QQQ and IWM, via a weekly ladder of synthetic notes, each with a three-year maturity, 30% downside coupon and principal barriers, and a coupon-memory feature. * CAYN seeks enhanced tax efficiency, improved coupon reliability and greater principal preservation relative to single notes and non-indexed worst-of ETFs. Metro-Chicago, Illinois, October 19, 2026- John Koudounis, President and CEO of Calamos, a pioneer in liquid alternatives, today announced the planned launch of the Calamos Least-Of Autocallable Income ETF (CAYN) on October 26, 2026. Calamos developed CAYN with MerQube and Citibank as the world's first indexed approach to autocallable income tied to the popular "worst-of" structured note strategy. "The autocallable ETF category is taking off, with growing investor demand for multiple strategies. Our planned launch of CAYN further demonstrates Calamos' leadership in the autocallable ETF space that we created with CAIE in 2025," said John Koudounis, President and CEO of Calamos. "We're excited to improve the least-of strategy and to soon offer another powerful product for income-oriented investors seeking higher coupons from equities." Calamos was named Asset Manager of the Year (AUM between $25 billion and $500 billion) at the 2026 MMI/Barron's Industry Awards. Its Autocallable ETF lineup has also received multiple awards alone in 2026, including Investment Product Innovation (MMI/Barron's) and, from SRP Americas, Best Structured ETF Solution and ETF Innovation of the Year.[1] "For investors looking for a worst-of autocallable solution, we've built the first indexed least-of autocallable strategy, designed to bring tax-efficiency, liquidity, and a degree of principal preservation and coupon reliability to the most popular product type in the legacy autocallable yield note market," said Matt Kaufman, Global Head of ETFs at Calamos. "CAYN will use the same 'Structured ETF' framework that has powered the success of CAIE, CAIQ and CAGE - trading an index on swap, an innovation that the worst-of autocallable strategy has never seen before in the ETF space. We look forward to expanding the Calamos Autocallable ETF family for investors seeking one of the most popular forms of autocallable income via the ETF wrapper." About the ETF. CAYN is designed to seek high, tax-efficient income by tying income and principal repayment to the weakest performer among three ETFs representing large-cap stocks (SPY), growth stocks (QQQ) and small-cap stocks (IWM). Rather than investing in a single worst-of autocallable note ("note") or a non-indexed worst-of autocallable ETF, CAYN provides exposure to a weekly laddered index of at least 52 synthetic worst-of autocallable notes, each with a three-year maturity and 30% downside coupon and principal barriers. When a note in the portfolio is called away, the principal is returned to the fund and reinvested in a new note with the same terms. Each note's three-year term is designed to allow more time to recover from market declines, seeking to reduce the risk of principal impairment. CAYN's index also features a "memory" mechanism that stores missed coupons and pays them once the worst-performing constituent is back above the coupon barrier. Calamos will trade the MerQube US Equity Least-Of Autocallable Index (MQAUTOWL) on swap. CAYN intends to take a multi-counterparty approach, with Citibank as the primary counterparty.

Before investing, carefully consider the fund's investment objectives, risks, charges and expenses. Please see the prospectus and summary prospectus containing this and other information which can be obtained by calling 1-866-363-9219. Read it carefully before investing. An investment in the Fund is subject to risks, and you could lose money on your investment in the Fund. There can be no assurance that the Fund will achieve its investment objective. Your investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The Fund also has specific principal risks, which are described below. More detailed information regarding these risks can be found in the Fund's prospectus. The principal risks of investing in the Calamos Least-of Autocallable Income Fund include: authorized participant concentration risk, autocallable structure risk, contingent income risk, early redemption risk, barrier risk, box spread risk, calculation methodology risk, cash holdings risk, correlation risk, costs of buying and selling fund shares, counterparty risk, credit risk, derivatives risk, equity securities risk, FLEX options risk, index risk, interest rate risk, investment in a subsidiary, laddered portfolio risk, liquidity risk, market maker risk, market risk, new fund risk, non-diversification risk, other investment companies risk, premium-discount risk, secondary market trading risk, swap arrangement risk, swap agreement termination risk, tax risk, trading issues risk, valuation risk. Autocallable Structure Risk - The Fund's returns are correlated to the performance of a theoretical portfolio of Autocallables reflected by the Autocallable Index. Autocallable notes have specific structural features that may be unfamiliar to many investors. Contingent Income Risk - Coupon payments from the Autocallables are not guaranteed and will not be made if the least performing Constituent falls below the Coupon Barrier on Observation Dates. This means the Fund may generate significantly less income than anticipated during market downturns. Barrier Risk - If the least-performing Constituent falls below the Maturity Barrier at the maturity of an Autocallable in the Index Portfolio, that portion of the Index Portfolio will be fully exposed to the negative performance of the least-performing Constituent from its initial level. This conditional protection creates a binary outcome that can result in sudden, significant losses if barriers are breached.
