According to the source, a post on X dated Oct 7, 2025 alleges SpaceX holds about $1 billion in Bitcoin (BTC), but there is no accompanying corporate filing or official statement from SpaceX or Elon Musk confirming this claim as of today, and SpaceX, as a private company, is not required to file periodic 10-Ks with the U.S. SEC (sources: X post; U.S. SEC guidance on public vs. private company reporting). Historically, confirmed corporate treasury allocations have driven immediate BTC upside and broader crypto beta, as when Tesla disclosed a $1.5 billion Bitcoin purchase in its 2020 Form 10-K on Feb 8, 2021 and markets rallied the same day (sources: Tesla 2020 Form 10-K; Reuters coverage Feb 8, 2021). Given the lack of primary confirmation here, traders should treat this as unverified headline risk and wait for validation via SpaceX corporate communications or Elon Musk’s verified X account before positioning (sources: SpaceX official communications; X verified account posts). If formal confirmation emerges, watch for knee-jerk moves in BTC spot and derivatives alongside sympathy bids in crypto-exposed equities such as MicroStrategy and Coinbase, a pattern observed around prior corporate BTC disclosures (sources: Reuters coverage of market reactions to Tesla and MicroStrategy announcements; MicroStrategy press releases). Until then, risk management favors avoiding leverage on unconfirmed news and setting alerts for any primary-source statements that would change the thesis (sources: historical reaction documented by Reuters; company filings and press releases).
