ProShares Bitcoin Strategy ETF (NYSEARCA:BITO) gives traditional brokerage investors Bitcoin exposure through CME-traded futures contracts rather than holding Bitcoin directly. That structure was groundbreaking when BITO launched in October 2021 as the first U.S. Bitcoin futures ETF, but it has become its central competitive challenge. Since spot Bitcoin ETFs from BlackRock, Fidelity, and others arrived in January 2024, BITO has faced persistent AUM outflows to lower-cost alternatives. The fund carries a 0.95% expense ratio, compared to roughly 0.25% for most spot competitors.
The price action reflects that pressure. BITO is down 21.4% year-to-date as of February 25, directly tracking a sharp Bitcoin selloff that erased a significant portion of BTC’s value in a matter of weeks. Bitcoin has since stabilized near $66,800, and BITO has bounced 4.3% over the past week, but the recovery has been tentative and sentiment remains cautious — a pattern consistent with a market still digesting the macro headwinds driving the selloff.
Macro Factor: Risk Appetite and the Regulatory Environment
The single biggest macro driver for BITO over the next 12 months is the combination of institutional risk appetite and the U.S. regulatory environment. The current administration has taken a crypto-friendly posture, supporting institutional interest. But Bitcoin has still sold off sharply in 2026 as broader risk sentiment deteriorated — the VIX has climbed to 19.55, up roughly 20% over the past month, signaling elevated fear that historically pressures risk assets like Bitcoin.
Prediction markets capture that split sentiment. Polymarket assigns a 38.5% probability to Bitcoin reaching $100,000 by year-end — a bullish scenario that would meaningfully lift BITO. Yet the same crowd sees a 76% implied probability of Bitcoin revisiting $55,000 at some point, reflecting how much downside risk remains priced in. For BITO investors, this wide dispersion of outcomes means the fund could swing dramatically in either direction, making macro sentiment monitoring essential rather than optional.
Watch the CBOE VIX (tracked at FRED) alongside SEC or CFTC rulemaking announcements. A sustained VIX move above 25, or a reversal of the current regulatory posture, would be a meaningful negative signal for BITO.
Micro Factor: AUM Trajectory and Futures Roll Cost
BITO’s futures-based structure creates a recurring cost spot ETF holders never pay: contango drag. Each month, the fund sells expiring futures and buys the next month’s contracts. When the futures curve slopes upward, BITO effectively buys high and sells low on every roll, a meaningful structural headwind in trending markets. With roughly $2.4 billion in net assets, BITO retains meaningful scale, but continued AUM outflows would compress that further, widening bid-ask spreads and reducing trading efficiency. Monitor monthly holdings and ProShares’ fact sheet updates for shifts in roll cost and AUM trend.
Bottom Line
If risk appetite recovers and the crypto-friendly regulatory environment holds, prediction markets assign a 38.5% probability to Bitcoin reaching $100,000 by year-end, which would be reflected in BITO’s price. Contango drag will continue eroding returns relative to spot ETFs regardless of Bitcoin’s direction.
