Tidal Trust II takes five Defiance 2x ETFs effective and files an AIMG summary prospectus
Tidal Trust II on Tuesday, September 8, 2026 filed a Rule 485(b) amendment, effective September 9, for five Defiance 2x ETFs and a summary prospectus for AIMG at 0.61%.
Five Defiance single-stock 2x ETFs that Tidal Trust II first registered on May 5, with blank tickers and a prospectus marked subject to completion, now have tickers on a Rule 485(b) post-effective amendment that becomes effective Wednesday, September 9.
Five Defiance 2x series, effective Wednesday
A Rule 485(b) amendment is the form that can take effect on a date the trust selects, typically to finish a new series that entered registration under Rule 485(a). Tuesday's paper does that for five Defiance Daily Target 2X Long funds. As registered in May and named in this amendment, each seeks 200% of the daily percentage change in one underlying stock.
The filing's series list now assigns the tickers that were blank in May:
An effective prospectus is permission to offer shares. It is not a listing, and Tuesday's amendment does not report a first trade.
AIMG summary prospectus
The second document is a Rule 497(k) summary prospectus dated September 8 for the Defiance AI Magnificent 10 ETF AIMG. It names The Nasdaq Stock Market as the listing exchange. The fund seeks to track the BITA AI Magnificent 10 Select Index, before fees and expenses. Final index constituents are equally weighted.
The fee table sets a 0.59% management fee and 0.02% of other expenses, including interest, for total annual fund operating expenses of 0.61%. Tidal Investments LLC, the adviser, pays the fund's ordinary expenses other than the advisory fee. Stephen Foy and Christopher P. Mullen have been jointly responsible for day-to-day management since the fund's inception in 2026.
This is not a new registration. Tidal Trust II already took AIMG's statutory prospectus effective on August 4, in a Rule 485(b) amendment that also recorded the series' name change from Defiance MAGA Seven ETF. Tuesday's paper is the summary prospectus under the new name.
