REX Shares and Tuttle Capital Management have launched a new leveraged ETF tied to Strive, one of the public companies building a large Bitcoin treasury.
The new fund, called the T-REX 2X Long ASST Daily Target ETF, trades under the ticker ASSX on Cboe. The ETF is designed to deliver 200% of the daily performance of Strive's common stock, ASST, before fees and expenses.
The launch gives traders a new way to take an amplified short-term position on a Bitcoin-focused public company without directly buying Bitcoin or ASST shares themselves.
But there is an important detail that could easily get lost in the headline: ASSX is not a 2X Bitcoin ETF. It does not hold Bitcoin and does not attempt to deliver twice Bitcoin's daily return. Instead, its target is based on the daily performance of Strive shares.
ASSX Starts Trading on Cboe
REX and Tuttle launched ASSX on September 18, 2026, with the fund beginning trading on Cboe under the ticker ASSX.
REX describes the product as the first U.S. ETF offering 2X daily long exposure to Strive, a Bitcoin-treasury company. The fund's investment objective is specifically tied to ASST's daily performance rather than the price of Bitcoin.
That makes ASSX part of a growing market for leveraged ETFs built around publicly traded companies with significant exposure to digital assets.
For traders who already follow Bitcoin treasury companies, the product adds another layer to an increasingly complex market: instead of simply buying a Bitcoin-related stock, investors can now use an ETF designed to magnify its daily moves.
How the 2X Exposure Actually Works
The basic idea behind ASSX is straightforward.
If ASST gains 5% during a trading day, ASSX seeks to gain approximately 10%, before fees, expenses and other factors affecting the fund's performance.
If ASST falls 5%, the same mechanism works in reverse, with ASSX targeting approximately a 10% decline for that day.
However, the word “daily” is critical.
REX states that the fund does not seek to achieve its investment objective for a period different from a single trading day. Its leverage is reset each day, which means an investor should not assume that holding ASSX for several days will simply produce twice ASST's total return.
Why ASSX Is Not the Same as a 2X Bitcoin ETF
This distinction matters because Strive is closely associated with Bitcoin.
Strive has adopted a Bitcoin-focused corporate strategy and holds a substantial amount of BTC. That gives its stock exposure to developments in the Bitcoin market, but ASST remains a company's stock rather than Bitcoin itself.
There are several factors between Bitcoin's price and ASSX's eventual performance.
- Bitcoin's price can influence the value of Strive's Bitcoin holdings.
- Changes in Bitcoin sentiment can influence demand for ASST shares.
- Strive's corporate decisions and capital structure can affect the stock.
- ASST can move independently of Bitcoin on some trading days.
- ASSX then targets 2X the daily move of ASST.
That means the relationship can be thought of as Bitcoin exposure through Strive, followed by daily leverage on Strive's stock.
It is therefore inaccurate to describe ASSX as simply “2X Bitcoin.”
Strive Holds 25,000 Bitcoin
The launch is attracting attention because of the size of Strive's Bitcoin treasury.
According to Cointelegraph, Strive currently holds approximately 25,000 BTC, making it the fifth-largest publicly traded corporate Bitcoin holder based on BitcoinTreasuries.NET data cited in the report.
The company also recently added 469 BTC, with the purchase financed through sales of SATA, its perpetual preferred stock, according to the report.
That treasury strategy is one of the main reasons Strive has become an increasingly watched stock among investors looking for equity-market exposure to Bitcoin.
But the value of Strive shares is not determined solely by the market value of its Bitcoin holdings.
Investors also have to consider the company's financing strategy, capital structure, future Bitcoin purchases and the valuation that the stock market assigns to the business.
Strive Stock Jumped 6.4% on Friday
The timing of the ASSX launch also comes as ASST has been attracting market attention.
Strive shares rose 6.4% on Friday to close at $30.09, according to the Cointelegraph report, which cited Yahoo Finance data.
The report also noted that the closing price was slightly above the $29.40 average 12-month analyst price target tracked by S&P Global.
That single-day move also illustrates why a leveraged product such as ASSX can attract active traders. A sizeable move in ASST can translate into a substantially larger percentage move in the leveraged ETF.
Of course, the same mechanism works when the stock falls.
The Daily Reset Is the Part Traders Need to Understand
One of the biggest differences between ASSX and simply holding ASST is the daily reset.
Suppose ASST rises sharply on one day and then gives back part of that gain the following day. A 2X daily ETF does not simply take the total two-day return of ASST and multiply it by two.
Instead, the fund resets its exposure after each trading session.
That creates what is commonly known as path dependency. The sequence of gains and losses can materially affect the final result when a leveraged ETF is held for longer than one day.
REX specifically warns that performance over periods longer than a single trading day can differ significantly from 200% of ASST's cumulative performance because of daily compounding and the fund's reset mechanism.
For that reason, ASSX is fundamentally designed around a daily trading objective rather than a promise of delivering 2X ASST's long-term return.
Why Traders May Find ASSX Interesting
The attraction is easy to understand.
A trader who expects ASST to move sharply higher during a particular session can use ASSX to seek approximately twice that daily move.
That provides a way to express a short-term bullish view on Strive without directly purchasing the underlying shares.
At the same time, the leverage makes the product considerably more sensitive to adverse moves.
A trader who gets the direction wrong can see losses accumulate much faster than they would from holding the underlying stock without leverage.
REX says the fund is intended for knowledgeable investors who understand the consequences of daily leveraged products, understand leverage risks and are willing to monitor their portfolios frequently.
ASSX Adds Another Layer to the Bitcoin Treasury Trade
The bigger story behind ASSX is not just the launch of one ETF.
It is the continued expansion of financial products built around companies that hold Bitcoin on their balance sheets.
Over the past few years, investors have gained several different ways to obtain Bitcoin-related exposure.
They can hold BTC directly, use a spot Bitcoin ETF, buy shares in a Bitcoin treasury company or trade financial products based on those companies.
ASSX takes that structure another step further by adding daily leverage to the stock of a Bitcoin treasury company.
The result is a product that sits somewhere between traditional equity trading and crypto-market speculation.
REX and Tuttle Are Expanding Their Leveraged ETF Lineup
ASSX is also not an isolated product from REX and Tuttle.
According to the companies, their lineup includes other 2X ETFs connected to crypto-related publicly traded companies, including Strategy, BitMine, Cipher Mining, Circle and SharpLink.
That suggests the issuers see continued demand for leveraged exposure to individual companies that are closely connected to the digital-asset market.
The approach gives traders a packaged ETF structure instead of requiring them to use traditional margin strategies or options to obtain amplified exposure.
For sophisticated traders, that can create another tool. For inexperienced investors, however, the mechanics can be much less intuitive than a conventional unleveraged ETF.
What Happens if Bitcoin Moves Sharply?
Bitcoin's price could become an important driver of ASST, but investors should not assume that every Bitcoin move will produce a matching move in the stock.
Strive's stock can react to Bitcoin's price, but it can also respond to company-specific news, capital raises, changes in its treasury strategy, investor demand and broader equity-market conditions.
ASSX then magnifies the daily move of that stock.
That creates a chain of exposure that can produce very different results from simply buying BTC.
For example, Bitcoin could rise while ASST performs differently because of stock-specific factors. In that situation, ASSX would follow ASST rather than Bitcoin.
This is why the underlying asset named in the fund's objective matters more than the broader “Bitcoin ETF” label sometimes attached to the story.
The Bigger Trend Behind Bitcoin Treasury Companies
Bitcoin treasury companies have become an increasingly visible part of the crypto-finance market.
The basic strategy is to hold Bitcoin as a significant corporate treasury asset while using the company's equity and other financing instruments to support its broader strategy.
Strive is one example of that model, and its approximately 25,000-BTC position has made ASST a stock that can attract both traditional equity investors and crypto-focused traders.
Products such as ASSX show how Wall Street-style financial engineering is developing around that trend.
Instead of only asking whether Bitcoin will rise or fall, traders can now take positions based on how a Bitcoin treasury company's shares react to the same market environment.
What Investors Should Watch With ASSX
Several factors will be important as ASSX develops a trading history.
- ASST volatility: Larger daily moves in Strive can produce larger moves in ASSX.
- Bitcoin volatility: Changes in BTC can influence sentiment around Bitcoin treasury companies.
- Daily compounding: Multi-day performance can differ significantly from simply doubling ASST's cumulative return.
- Company-specific events: Financing, treasury purchases and corporate announcements can move ASST independently of Bitcoin.
- Liquidity and trading conditions: The ETF's market price can be affected by trading activity and market conditions.
These factors make ASSX a very different instrument from a traditional Bitcoin ETF.

Bottom Line
REX Shares and Tuttle Capital Management have launched ASSX, a 2X daily leveraged ETF built around Strive's ASST shares.
The ETF began trading on Cboe on September 18, 2026, and seeks to deliver 200% of ASST's daily performance before fees and expenses.
The most important point for crypto investors is that ASSX is not a leveraged Bitcoin ETF. It does not hold BTC and does not target twice Bitcoin's return. Its exposure is to Strive's stock, and Strive's Bitcoin treasury is only one factor that can influence that stock.
With Strive holding approximately 25,000 BTC and continuing to build its Bitcoin-focused strategy, ASST has become an increasingly visible bridge between traditional equities and the crypto market.
ASSX takes that connection one step further by adding daily leverage. That could make it attractive to active traders looking for amplified short-term exposure, while the daily reset and compounding effects make it a product that requires a clear understanding of how leveraged ETFs work.
In short, the launch is another sign that the Bitcoin treasury trend is moving beyond simply buying and holding BTC. Financial markets are increasingly creating products around the companies, stocks and strategies that sit around the Bitcoin ecosystem.
