REX Shares and Tuttle Capital Management have launched ASSX, the T-REX 2X Long ASST Daily Target ETF, on the Cboe BZX Exchange. The fund gives investors two times the daily price movement of Strive, Inc. (NASDAQ: ASST), a Nasdaq-listed company that holds Bitcoin as a core treasury asset. According to the issuers, it is the first U.S. exchange-traded fund to offer 2x daily long exposure to Strive stock.

ASSX seeks 200% of the daily performance of ASST before fees and expenses. That target applies to a single trading day and resets every session. The launch also marks a notable extension of the leveraged single-stock ETF format into the crypto-treasury corner of the market: rather than wrapping Bitcoin itself, it applies the T-REX structure to a company whose principal link to the asset is its balance sheet.

Launch and Regulatory Filing

ASSX began trading on September 18, 2026, under the T-REX brand, the shared REX-Tuttle family of leveraged single-stock ETFs. The underlying stock is Strive, Inc. (ASST), a company listed on the Nasdaq that holds Bitcoin on its corporate balance sheet The launch gives traders a leveraged tool tied to a Bitcoin-treasury equity rather than to Bitcoin itself.

An SEC supplement filed on September 4, 2026 named the T-REX 2X Long ASST Daily Target ETF, confirmed the ASSX ticker, and identified the Cboe BZX Exchange as the listing venue. The filing sits within the ETF Opportunities Trust, the registered vehicle that houses the REX-Tuttle T-REX product family, according to the filing. The fund's listing information is also available on the Cboe website.

ASSX is not a spot Bitcoin ETF and does not hold Bitcoin directly. Instead, it tracks the stock of Strive, a company whose value is tied in part to Bitcoin because of its treasury strategy. That distinction matters for readers: the fund's results depend on how ASST trades as an equity, which reflects both broader stock-market conditions and the market's view of Strive's Bitcoin holdings. Investors who already follow REX's earlier 2x leveraged ETF tied to Strive will recognize the structure, as the new fund expands that existing product line with a fresh listing on a major U.S. exchange.

How 2x Daily Exposure Works

A 2x daily ETF typically uses financial instruments, most commonly swaps, to deliver twice the price change of its target stock within a single trading day. If ASST rises 3% on a given day, ASSX aims to return roughly 6% that day before fees; if ASST falls 3%, the fund aims to fall roughly 6%. ASSX seeks 200% of ASST's daily performance before fees and expenses, and the objective is strictly a one-day target.

The daily reset creates a compounding effect over time. In a volatile market, a fund that resets leverage every day can lose ground even if the underlying stock ends the week flat. This effect, sometimes called "volatility decay," means holding a leveraged ETF for weeks or months can produce results very different from doubling the stock's long-term return. For that reason, ASSX's objective is not designed to track returns over any longer period.

Strive holds Bitcoin as part of its corporate treasury, so ASST's price already reflects Bitcoin's volatility to some degree. In practice this creates layered exposure: conditions in crypto markets shape Bitcoin's price, which feeds into the value of Strive's treasury, which in turn helps drive ASST's share price, which ASSX then doubles on a one-day basis. Adding 2x daily leverage on top of that exposure amplifies both potential gains and potential losses. Bitcoin was trading near $81,510 at the time of writing, up about 1.5% over the past 24 hours, underscoring how quickly the underlying environment can shift.

Fees, Assets, and Market Context

The fund launched with $250,000 in initial assets and carries a 1.5% total expense ratio. That cost is higher than a plain index ETF, which is common for leveraged products that require active derivative management. Anyone considering ASSX should review the official fund documents on the REX Shares issuer page before making any investment decision, as the fund's prospectus details the full range of risks specific to this structure. With a starting asset base that small, the fund's reported asset level and trading activity are the most direct observable indicators of early uptake, and investors can follow both through official issuer and exchange disclosures.

For context on how broader crypto conditions may affect Strive and, by extension, ASSX, the market sentiment index currently reads 70, a level described as "Greed." Higher sentiment can support Bitcoin-linked equities such as ASST in the short term, although market conditions can change quickly.
