This year, the bell finally rang for SpaceX. Its listing became one of the largest public debuts on record, and Anthropic and OpenAI are now taking their own steps toward the public markets. Taken together, these companies could introduce more than $3 trillion of new market value to public investors in a matter of months, representing a concentration of value entering the public markets in a single window that has few precedents.

SpaceX prices its IPO Thursday, with first trades Friday on the Nasdaq under ticker SPCX, at a fixed $135 per share. The base raise is $75 billion, rising toward $86 billion if underwriters exercise the over-allotment, the largest offering in history by a wide margin. In the same stretch, Anthropic and OpenAI each confidentially filed draft S-1 paperwork with the SEC. Anthropic filed first, on the heels of a funding round valuing the company near $965 billion. OpenAI followed

On May 11, 2026 SpaceX filed its initial Form S-1, and on June 3 the company filed an amended S-1/A that, unusually, set an exact offering price rather than a range: 555,555,555 Class A shares at $135.00, raising approximately $75 billion at a $1.77 trillion fully diluted valuation. Shares are expected to begin trading on Nasdaq under the ticker SPCX later this month, per press reports. The size is unprecedented — the largest IPO in U.S. history, twice the prior record.

In December 2024, Bloomberg reported a secondary share sale that valued the company at about $350 billion. Separately, Reuters reported in late 2025 that SpaceX was exploring an IPO that could raise more than $25 billion and value the company at over $1 trillion. Even taking the more conservative $350 billion figure, SpaceX would arrive at the public markets as one of the largest companies ever to list.bThat is what makes a potential SpaceX IPO so different.

Few private companies attract the level of sustained institutional attention that SpaceX does — and for good reason. Across the dimensions that matter most to sophisticated investors evaluating late-stage private opportunities — market position, financial profile, and path to liquidity — SpaceX presents a compelling case. It also carries at least one meaningful new variable worth watching carefully.

Value creation is staying private. Liquidity is learning to follow it as venture secondaries become a crucial on-ramp. For most of modern venture history, the script was straightforward: invest early, support the company, and wait for an IPO or acquisition to unlock returns. That script is now being rewritten as two powerful signals are converging.
