According to @rovercrc, ARK Invest bought about $145,000,000 worth of Bitcoin, stated in an X post on Sep 11, 2025, with no supporting documentation or links included in the post, source: @rovercrc on X, Sep 11, 2025. The post does not clarify whether the purchase was executed via an ETF, fund vehicle, or corporate treasury, which limits immediate verification pathways for traders, source: @rovercrc on X, Sep 11, 2025. Given the unverified nature of the claim, traders may treat it as a headline-driven sentiment catalyst and wait for official confirmation before adjusting exposure, source: @rovercrc on X, Sep 11, 2025. Until confirmation, traders can monitor BTC spot-futures basis, funding rates, and order book liquidity for potential headline-induced volatility and slippage risk, source: @rovercrc on X, Sep 11, 2025.
