ProShares Launched a 2x Long-and-Short Bitcoin ETF Pair

ProShares launched the Ultra Bitcoin ETF and UltraShort Bitcoin ETF on April 2, 2024, giving U.S. exchange investors a new pair of instruments targeting twice bitcoin's daily move in opposite directions. BITU sought 2x the daily performance of the Bloomberg Bitcoin Index; SBIT sought -2x. Both began trading on NYSE Arca under those ticker symbols.

The launch mattered because it extended bitcoin's regulated-market wrapper beyond unleveraged exposure. After the Securities and Exchange Commission approved exchange rule changes for multiple spot bitcoin products on January 10, 2024, ProShares was offering a way to magnify, short or hedge a single day's bitcoin move through brokerage accounts. That convenience came with a structure whose behavior could diverge sharply from a simple long-term multiple of bitcoin.

What the funds promised

The March 31, 2024 prospectus said BITU would seek daily investment results, before fees and expenses, equal to two times the Bloomberg Bitcoin Index. SBIT would seek two times the inverse of the same index. Each disclosed total annual operating expenses of 0.95%.

The word daily was the controlling limitation. A 3% index rise over one fund-measurement day implied a target near 6% for BITU and near -6% for SBIT before fees, expenses, financing costs and tracking differences. Those figures are arithmetic illustrations, not reported April 2 returns. The funds did not promise 2x or -2x over a week, month or other holding period.

Daily rebalancing and compounding meant multi-day results could be higher or lower than twice the index's cumulative move, potentially by a significant amount. Volatility could worsen that gap. The filing warned that BITU's leverage increased the possibility of total loss and that an index decline approaching 50% at any point in a day could exhaust an investment. SBIT carried the mirror risk when bitcoin rose.

Bitcoin exposure without holding bitcoin

Neither fund directly held bitcoin at launch. The issuer's April 2 announcement made that explicit, and the prospectus described swaps as the principal exposure tool, with cash balances generally held in short-term money-market instruments. The strategy therefore added derivative-counterparty, collateral, liquidity and tracking risks to bitcoin's own volatility.

That distinction also prevents a misleading label. BITU and SBIT were exchange-traded funds linked to bitcoin returns, but they were not spot bitcoin trusts holding coins for shareholders. The SEC filing stated that neither the SEC nor the Commodity Futures Trading Commission had approved or disapproved the securities or passed on the prospectus's adequacy. Registration and exchange listing were not government endorsements of bitcoin or of the funds' safety.

Why April 2 changed the market menu

ProShares described BITU as the first ETF targeting 2x daily bitcoin returns and SBIT as the first targeting -2x. A contemporaneous ETF.com report independently recorded the launch and the 0.95% expense ratios, while Nasdaq Trader's April 2 information-circular list identified both products and NYSE Arca as their listing venue.

The institutional significance was access, not proof of demand or performance. Traders could express amplified bullish or bearish views without opening a crypto-derivatives account or directly shorting bitcoin, and holders of other bitcoin exposure gained a brokerage-traded hedging instrument. But no event-day source established durable liquidity, accurate long-run tracking or investor outcomes.

For the April 2 record, the verified development is narrow: two daily-reset bitcoin-linked ETFs entered the U.S. market with opposite 2x objectives. Whether that access improved risk management or simply made bitcoin speculation easier remained an interpretation, not an event-day fact.
