\u201cIt is now apparent that Jane Street cut their IBIT and FBTC holdings by roughly 70% in Q1 based on 13F filings,\u201d Parker wrote on X. \u201cDid they just outright sell or more likely, did they make a HUGE profit on their short derivatives, which they don\u2019t have to report?

Will The Bitcoin Price Rally Now?<\/h2>\n
The filing does not show Jane Street\u2019s derivatives exposure, nor does it establish whether the firm was directionally bearish, hedged, or engaged in ETF arbitrage and market-making activity. That limitation is central to the debate. A 13F captures certain long holdings at quarter-end, but it does not give a complete view of options, swaps, futures, or short exposure that could materially change the economic interpretation of the reported cuts.<\/p>\n
Still, the reduction has become a focal point because of earlier claims that Bitcoin\u2019s price discovery may have been distorted by the mechanics of spot ETF trading. Bitwise advisor Jeff Park wrote that Jane Street had \u201cslashed its Bitcoin ETF exposure in Q1 2026,\u201d cutting IBIT by approximately 71% and FBTC by approximately 60%, before adding: \u201cPrice discovery is back on the menu.\u201d<\/p>\n
Park\u2019s broader argument<\/a> is not that one firm explicitly suppressed Bitcoin\u2019s price, but that the ETF structure creates a complex market-making environment in which authorized participants can use creation and redemption mechanics, derivatives, and futures hedges in ways that may weaken the link between ETF demand and spot Bitcoin buying. In a prior post, he framed the issue as structural rather than conspiratorial.<\/p>\n
