Tidal Trust I registers 12 new SoFi and Unlimited ETFs
Tidal Trust I filed three Form 485BPOS amendments on Friday, September 4, 2026, putting 12 new SoFi and Unlimited ETF series on effective prospectuses.
Tidal Trust I on Friday filed three Rule 485(b) post-effective amendments covering 12 new ETF series, seven under the SoFi name and five under Unlimited. A 485(b) amendment is the dated-effective update used once a registration is past staff review; it is not a listing. The SoFi statements of additional information say those funds have not commenced operations and that no shares were outstanding as of the SAI dates.
Post-Effective Amendment No. 331, covering three SoFi thematic index funds, is dated to become effective Saturday, September 6. No. 332, covering four more SoFi index funds, is dated Monday, September 7. No. 333, covering five Unlimited Dynamic Leverage funds, became effective Friday, September 4, the day it was filed. As of Monday, all three prospectuses are effective. Tidal Investments LLC is the adviser on every series.
The 12 series
Amendments 331 and 332 say they are being filed to respond to staff comments on the SoFi registrations and to make other changes Rule 485(b) allows. The SoFi funds are not currently sub-advised. Unlimited Funds, Inc. is named as sub-adviser to the Dynamic Leverage series. Every prospectus names NYSE Arca as the listing exchange; that is the paper's intended venue, not a first-trade notice.
The SoFi series are index funds with total annual operating expenses of 0.35% to 0.59%. The Unlimited series are actively managed and seek capital appreciation, with estimated total expenses of 0.52% to 1.18%. Unlimited figures are estimated for the initial fiscal period and, where shown, include acquired-fund fees.
Each SoFi fund has an 80% policy, changeable on 60 days' notice, to hold component securities of its index in the named theme: AI power-grid companies, on-chain companies, robotaxi and autonomous-vehicle companies, high-efficiency companies, emerging-market high-efficiency companies, or U.S. risk-off or risk-on companies. SoFi already lists other series on the same trust, including SoFi Agentic AI ETF AGIQ.
On the Unlimited side, the gold and bitcoin totals include acquired-fund fees of 0.09 and 0.23 percentage points on top of a 0.95% management fee. Oil's table shows the 0.95% management fee as the whole expense ratio. U.S. stocks and Treasuries carry a 0.49% management fee. The advisory-agreement exhibit lists "Commencement of Operations" as the fee effective date for all five, which is a contractual condition, not evidence that trading has started.
