- • Put options on IBIT fell 52.75% during the same period, declining to 143,300 underlying shares, indicating a sharp reduction in downside hedging activity among institutional investors.
- • The combined shift toward calls and away from puts reflects a significant rebalancing of risk positioning in Bitcoin ETF derivatives, with non-option IBIT shares also rising 11.94% during Q2.

Summary
UBS significantly increased its bullish exposure to BlackRock's Bitcoin ETF (IBIT) during the second quarter of 2026, with call option positions expanding dramatically while protective put positions contracted sharply. According to UBS's August 13 filing, call options on IBIT surged 24-fold to 1.95 million underlying share equivalents, up from 80,000 shares in March. Simultaneously, put option exposure fell 52.75% to 143,300 underlying shares, reflecting a marked rotation away from downside protection.
This rebalancing demonstrates a substantial shift in institutional sentiment toward Bitcoin ETF derivatives. The magnitude of the call increase—from a relatively modest 80,000 shares to nearly 2 million—suggests either aggressive new positioning by UBS or substantial internal reallocation toward upside participation. The concurrent decline in puts indicates reduced hedging demands, which typically occurs when investors grow more confident in directional positioning or view current valuations as less risky.
The positioning change occurred alongside modest appreciation in non-option IBIT holdings, which rose 11.94% during the quarter. This suggests that UBS employed a layered strategy combining direct ETF exposure with leveraged call positions to amplify potential upside, while simultaneously reducing tail-risk hedges. For institutional investors tracking large asset manager positioning, these movements often signal conviction levels and can indicate sentiment shifts across the broader alternatives market.
The filing provides a window into how major institutional players are structuring Bitcoin exposure through regulated ETF vehicles rather than direct spot or futures positions, reflecting the maturation of the cryptocurrency derivatives market and institutional comfort with standardized Bitcoin investment vehicles.
