SpaceX S-1 discloses 18,712 BTC ($1.45B) as XRP volatility tightens; DOGE creator pushes back

SpaceX filed an S-1 with the SEC for a Nasdaq IPO under ticker SPCX and disclosed 18,712 BTC worth about $1.45 billion, placing it among the world's top seven corporate Bitcoin holders. XRP traded in a tight $1.36–$1.37 band as Bollinger Bands compressed, while spot crypto ETFs saw -$1.1 billion in outflows and spot XRP ETFs reached $1.134 billion in total capital. Separately, Dogecoin co-creator Billy Markus replied to a $20 trillion market-cap claim on May 21, 2026, calling the idea less boring but implicitly unrealistic.
