A historic stock market debut is imminent, with SpaceX's initial public offering just six weeks away, and it may draw interest away from cryptocurrencies. SpaceX has filed a confidential S-1 with the SEC, aiming for a $75 billion capital raise at a valuation of $1.75 trillion. If successful, this will be the largest stock market debut in history, surpassing Saudi Aramco's $29 billion record in 2019.

Other notable listings, including OpenAI and Anthropic, are also on the horizon, with the potential to raise over $60 billion. The combined capital raised by these companies could exceed $240 billion from June to the end of the year, a figure that surpasses every venture-backed US IPO since 2000. This massive influx of capital may lead to a rotation out of equities and into these new listings, potentially impacting the liquidity of bitcoin and other cryptocurrencies. Crypto assets are part of the same risk-on liquidity pool as tech and AI equities, and when speculative capital leaves equities for an IPO allocation, it may also leave the crypto market.

Historical parallels, such as Coinbase's listing in 2021, suggest that institutional milestones can mark the top of a cycle rather than the beginning. The upcoming SpaceX listing has two features that connect directly to crypto flows: a 30% retail allocation and the company's significant bitcoin holdings. The impact of this IPO on the crypto market will be closely watched, particularly during the roadshow window in May and June.
