ProShares' Bitcoin Futures ETF (BITO) marked a historic milestone by listing on NYSE Arca. However, Bitcoin futures ETFs operate differently from spot Bitcoin ETFs and come with hidden costs. FTX.US President Brett Harrison demystified these mechanisms in a detailed Twitter thread.
ETF Arbitrage Mechanics
Brett Harrison explains that ETF pricing relies on the "creation and redemption" process between Authorized Participants (APs) and fund managers:
- Secondary Market Trading: Retail investors buy/sell ETF shares on exchanges.
- Primary Market Mechanism: APs exchange underlying assets (e.g., futures contracts) for ETF shares (or vice versa), ensuring price alignment.
"When the basket’s asset value exceeds the ETF price, APs buy ETF shares, redeem them for the underlying assets, and sell those assets for profit. This arbitrage keeps ETF prices anchored."
Why BITO Doesn’t Fully Track Bitcoin
BITO holds two components:
- Short-term CME Bitcoin futures (tightly correlated to spot BTC via arbitrage).
- Cash reserves (U.S. Treasuries, repos), diluting direct Bitcoin exposure.
Hidden Costs: Contango & Roll Yield
- Contango: Longer-dated futures trade at a premium due to bullish sentiment and interest rates.
- Roll Yield Loss: BITO sells expiring contracts to buy pricier longer-dated ones, incurring recurring costs.

"BITO’s 1% gain when Bitcoin rises 1% is unlikely—cash reserves and roll costs reduce returns." — Brett Harrison
Alternatives for Retail Investors
While BITO advances crypto’s institutional adoption, FTX.US’s acquisition of LedgerX (a CFTC-regulated platform) will enable:
- Retail-accessible crypto futures/options.
- Equity token derivatives (per Sam Bankman-Fried’s vision).
