REX Shares launches REX Bitcoin Corporate Treasury Convertible Bond ETF

• REX Shares has launched BMAX ETF for Bitcoin treasury bonds.
• BMAX offers debt stability and equity upside via Strategy.
• The fund carries risks like volatility and regulatory scrutiny.

On March 14, 2025, REX Shares, a Miami-based innovator in exchange-traded products, unveiled a groundbreaking financial instrument: the REX Bitcoin Corporate Treasury Convertible Bond ETF, trading under the ticker NASDAQ: BMAX.

This first-of-its-kind fund offers investors a unique opportunity to tap into convertible bonds issued by companies that hold Bitcoin (BTC) on their balance sheets.

With Bitcoin’s price climbing 2.1% to $83,400 and Strategy (formerly MicroStrategy) gaining 5.1% in morning trading on launch day, the timing underscores growing interest in Bitcoin-linked corporate strategies.

A convertible Bitcoin treasury bond for retail investors

The concept behind BMAX traces back to a playbook pioneered by Michael Saylor, Chairman of Strategy. His company famously began stacking Bitcoin on its balance sheet, funding the purchases partly through convertible bonds and new stock offerings.

Other firms followed suit, creating a niche asset class that blends the stability of debt with the growth potential of equity.

However, until now, these bonds were largely out of reach for individual investors, locked behind complex market barriers. BMAX changes that, packaging this strategy into a single, actively managed ETF that simplifies access for retail investors and advisors alike.

Greg King, CEO of REX Financial, hailed the launch of the REX Bitcoin Corporate Treasury Convertible Bond ETF as a milestone. “BMAX is the first ETF giving everyday investors a shot at convertible bonds tied to companies embracing Bitcoin as a treasury asset,” he said.

With over $6 billion in assets under management, REX is no stranger to alternative-strategy ETFs, and BMAX fits squarely into its mission of delivering innovative exposure. The fund’s concentrated focus zeroes in on issuers like Strategy, a heavyweight in Bitcoin-backed debt, offering a regulated way to ride the crypto wave without directly owning Bitcoin.

What sets BMAX apart is its hybrid appeal. Convertible bonds, by nature, carry traits of both debt and equity. They provide a steady income stream like traditional bonds but can convert into stock, capturing upside if the issuing company’s share price soars—say, on a Bitcoin rally.

For investors wary of Bitcoin’s wild price swings, BMAX offers a more conservative entry point, balancing debt’s relative calm with equity’s potential kick. It’s a middle ground for those intrigued by crypto but hesitant to dive in headfirst.

BMAX’s risks

Still, BMAX isn’t without its hazards. The fund’s prospectus lays out a laundry list of risks, from Bitcoin’s notorious volatility to the unique challenges faced by companies like Strategy.

These “Bitcoin Corporate Treasury Companies” grapple with speculative hype, regulatory scrutiny, and accounting quirks—like impairment losses when the Bitcoin (BTC) price dips.

Strategy, a key holding due to its outsized market cap, adds its own layer of risk, tied to both its Bitcoin hoard and its legacy software business.

Interest rate shifts, liquidity concerns, and even tax implications (BMAX is taxed as a C-corporation, unlike most ETFs) further complicate the picture.

However, despite the risks, BMAX signals a maturing crypto market where indirect exposure is gaining traction. Distributed by Foreside Fund Services, LLC, and backed by REX’s expertise, the ETF opens a door to a strategy once reserved for institutional players.

As Bitcoin cements its role in corporate treasuries, BMAX offers a fresh lens on the intersection of traditional finance and digital assets—proving that innovation, even in ETFs, keeps pace with a fast-evolving world.
