Eric Balchunas, a senior ETF analyst at Bloomberg Intelligence, has highlighted a correlation between spikes in trading volume for BITO, the ProShares Bitcoin Strategy ETF that holds Bitcoin futures contracts, and subsequent price reversals in IBIT, BlackRock's spot Bitcoin ETF. His analysis suggests that rising activity in BITO may point to a heating basis trade — a strategy in which traders exploit the premium between futures prices and spot prices by going long on spot Bitcoin exposure and short on futures. When that premium widens, basis trade activity tends to intensify, and volume in futures-linked products like BITO can serve as a proxy for tracking that dynamic.

Key Development

The broader crypto market is showing mixed signals, but recent trading activity around BITO has drawn attention. Balchunas noted a notable relationship between sharp increases in BITO volume and later reversals in IBIT's price action. The observation centers on whether elevated BITO trading activity can serve as a useful signal for traders tracking IBIT and related market behavior.

The reported correlation also comes as traders continue to follow activity across Bitcoin-linked products and the wider altcoin market. The interplay between futures-based and spot Bitcoin ETFs has been a recurring focus since the SEC approved spot Bitcoin ETFs in January 2024, which gave investors direct spot exposure previously unavailable through products like BITO. According to the source, sustained or explosive volume trends in BITO could influence how participants assess trading conditions involving IBIT.

Essentials

The analysis was attributed to Eric Balchunas and focused on volume correlation between BITO and IBIT in July 2026. The core point was that BITO volume spikes have appeared alongside later IBIT price reversals, suggesting a relationship that traders may incorporate into their market observations.

The Numbers

The source did not provide specific current volume figures for BITO. Instead, the focus was on observed trading behavior and its possible implications. Balchunas' analysis pointed to a potential increase in trading activity, with recent volume spikes potentially contributing to greater volatility in IBIT.

BITO launched in October 2021 as the first U.S. Bitcoin futures ETF, providing investors with regulated exposure to Bitcoin through CME futures contracts rather than direct spot holdings. IBIT, by contrast, holds actual Bitcoin and has become one of the most successful ETF launches on record, accumulating tens of billions in assets since its January 2024 debut. The coexistence of these two product types has created observable relationships between their trading patterns, as both derive value from the same underlying asset. The source noted that, in past market behavior, unusual trading volumes have often preceded price shifts, making volume activity an important data point for market participants.

What Traders Are Watching

Market participants are expected to continue watching BITO trading volume in the coming weeks for any further signs of a relationship with IBIT price movements. The correlation identified by Balchunas suggests that continued increases in volume may coincide with larger market moves, although the source did not provide a forecast for future prices or trading outcomes.
