REX Launches 2x Leveraged ETF Tied to Strive's 25,000-BTC Balance Sheet
A new leveraged fund began trading on Cboe on Sept. 18, putting an aggressive wrapper around one of the more Bitcoin-exposed equities in the public markets. ASSX, sponsored by REX Shares and advised by Tuttle Capital Management, seeks 200% of the daily share performance of Strive Inc. before fees and expenses. Strive carries 25,000 Bitcoin on its balance sheet, which means the ETF amplifies not just ordinary equity risk but the volatility of a company whose fortunes move with the cryptocurrency market.
How ASSX Constructs Its 2x Exposure
Crypto News reported the details of the fund’s structure as filed with the SEC. REX describes ASSX as “the first ETF in the U.S. offering 2x daily long exposure to ASST,” a claim supported by a Cboe certification the exchange filed on Sept. 15. The fund carries a 1.5% total expense ratio, with Tuttle Capital Management serving as adviser.
The mechanics hinge on a daily leverage reset. Each trading session closes and reopens at the targeted 2x ratio, which means multi-day holding periods generate compounding effects that can push actual returns well away from twice ASST’s cumulative move. The fund can produce losses across a longer stretch even when Strive’s stock finishes that period higher. REX achieves the exposure through derivatives, primarily swaps, and the fund does not hold Strive shares outright.

Two risk thresholds define the practical stakes. A 1% daily decline in ASST translates into roughly a 2% decline in the fund before financing and operating costs. More severely, REX’s disclosure states that an adverse ASST move of more than 50% in a single trading day could wipe out an investor’s principal entirely. Those are not theoretical extremes. Given Strive’s Bitcoin treasury, the stock can gap sharply on cryptocurrency-driven sessions.
One further point separates ASSX from a direct Bitcoin play. The fund does not hold Bitcoin and does not seek twice Bitcoin’s daily price change. Its reference asset is Strive common stock, which bundles corporate risk with Bitcoin-treasury exposure. Shareholders in ASSX receive no voting rights or distributions attached to Strive shares.
Variance Geometry That Poker Bankroll Rules Were Built For
The editorial team at Pokeriukas, which covers the poker community and its surrounding culture, draws a structural comparison between ASSX’s risk profile and a problem disciplined card players know well. The 2x loss amplification and the 50% single-day wipe threshold describe a situation where downside accelerates faster than intuition suggests, exactly the dynamic that emerges when a poker player overcommits to a high-variance hand without calibrating position size to bankroll depth.
Experienced players solve that problem with explicit staking rules that cap how much of a total stack can ride on any single volatile spot. The Pokeriukas editorial team points to pokeriukas.com as a resource that lays out that staking-and-variance framework in plain language, noting that the underlying math applies whether the high-variance position is a bluff on a wet board or a leveraged ETF tied to a Bitcoin treasury.
Strive’s Bitcoin Treasury and the SATA Financing Engine
The 25,000 BTC figure reflects a holding built incrementally through a preferred-share financing structure. Strive’s latest filing showed that position as of Sept. 11, following a purchase of 469 BTC made between Sept. 8 and Sept. 11 at an average price of $77,954 per coin including fees. That transaction lifted holdings from 24,531 BTC the prior week.
The buying was funded through Strive’s SATA preferred shares. A Sept. 14 Form 8-K showed cash and cash equivalents of $204.2 million, with the fair value of the company’s 505,000 Strategy STRC preferred shares recorded at $49.813 million. SATA preferred shares outstanding rose by 402,541 during the period to 10,397,966. Chairman and CEO Matt Cole noted that “100% of the capital raised came from SATA,” and added that the preferred stock had crossed $1 billion in notional value outstanding.
By reported holdings, BitcoinTreasuries.net ranks Strive fifth among public companies, behind Strategy, Twenty One Capital, Metaplanet, and MARA Holdings. That ranking frames ASST not as a Bitcoin proxy in the strictest sense but as a meaningful satellite, a company large enough in its Bitcoin exposure to move on crypto market events while also carrying the full range of corporate-level risks.
First-Day Trading and the Broader T-REX Lineup
Strive’s stock gave ASSX a favorable debut. On Sept. 18, ASST rose 6.4%, closing at $30.09 on volume of roughly 16.1 million shares. ASSX opened at $27.78 and finished at $28.27, with 123,946 shares traded on the day.
The fund slots into REX’s T-REX lineup alongside several other 2x daily products tied to individual equities and one cryptocurrency. That roster includes separate leveraged funds linked to Strategy, BitMine, Cipher Mining, Circle, and SharpLink, as well as BTCL, a 2x daily product referenced directly to spot Bitcoin. ASSX differs from BTCL in a consequential way.
Matt Tuttle, CEO of Tuttle Capital Management, captured the practical pitch at launch. “ASST moves, and it moves with bitcoin,” he said, describing ASSX as a vehicle suited to single-day positions. That framing also carries its own caveat. The fund’s formal objective is tied to ASST’s daily share performance, not to Bitcoin’s price, and the gap between those two things can widen without notice on any given session.
