SpaceX’s initial public offering has expanded to a total of $85.7 billion after underwriters exercised a so‑called “greenshoe” overallotment option, according to a report from CNBC. The move increases the size of the already large listing and signals that banks saw sufficient investor demand to sell additional shares beyond the original IPO allocation.
While CNBC’s report is currently the primary detailed public account of the transaction, the development marks a key financial milestone for the company as it transitions into life as a public stock.
What SpaceX and its underwriters just did
CNBC reported that the total amount raised in SpaceX’s IPO reached $85.7 billion after underwriters exercised the “greenshoe,” a contractual option that allows them to purchase and sell extra shares—typically up to 15% more than the base offering—if demand is strong.
In a standard IPO structure, the company and its underwriting banks agree in advance that the banks may sell more shares than initially planned. If the stock trades well, underwriters exercise the greenshoe to buy those extra shares from the company or existing shareholders and deliver them to investors who bought in the overallotment. CNBC’s account indicates that this mechanism was used in SpaceX’s deal, pushing the total raise to the $85.7 billion figure.
CNBC did not, in the report cited, break down how much of the $85.7 billion reflects new capital raised for SpaceX versus shares sold by existing investors, nor did it specify the exact percentage size of the greenshoe. Those details, if disclosed in regulatory filings, were not summarized in the available reporting.
How a greenshoe works in an IPO
The “greenshoe” option—named after the Green Shoe Manufacturing Company, an early user of the mechanism—is a common feature in large IPOs. CNBC’s description of the SpaceX deal aligns with the standard structure:
- Underwriters initially allocate more shares to investors than the base offering size.
- If the stock price holds up or rises after trading begins, underwriters exercise the option to buy those extra shares at the IPO price.
- This allows them to cover their short position (created by selling more shares than they initially had) and helps stabilize trading.
In practice, this means the final size of an IPO is often only known after the banks decide whether to use the greenshoe. CNBC’s reporting that the option was exercised in SpaceX’s case clarifies that the deal reached its expanded maximum, at least as structured in the underwriting agreement.
Why the $85.7 billion figure matters
The $85.7 billion total, as reported by CNBC, underscores the scale of investor interest in SpaceX’s public listing. While CNBC’s article is the main detailed source for this number at present, it indicates that:
- The IPO was structured with room to grow via the greenshoe, and
- Underwriters judged market demand to be strong enough to sell the additional shares.
In large offerings, exercising the greenshoe can serve two purposes: it increases the total capital raised and can help smooth trading in the early days by giving banks more flexibility to manage supply and demand. CNBC’s report suggests SpaceX’s IPO followed this familiar pattern, with the final tally only becoming clear once the overallotment decision was made.
The report did not provide a precise timeline for when the greenshoe was exercised, beyond indicating that the total raise figure reflects that step and that this update came roughly a day before the latest coverage.
What is confirmed and what is still limited
Based on CNBC’s event‑direct reporting, the following points are supported:
- SpaceX completed an IPO.
- The IPO included a greenshoe overallotment option.
- Underwriters exercised that option.
- The total raise associated with the IPO reached $85.7 billion after the greenshoe was used.
Independent corroboration of the exact size of the raise and the detailed structure of the transaction remains limited in publicly accessible coverage at this stage. Additional regulatory filings and disclosures, once fully reviewed, may either confirm or refine the numbers and breakdown reported by CNBC.
Because CNBC is currently the main detailed source, some aspects—such as the precise split between primary (new) shares and secondary (existing) shares, and the identities of all underwriting banks—are not fully described in the available summary. Readers should treat the $85.7 billion figure and the description of the greenshoe’s use as grounded in CNBC’s reporting, with the understanding that more granular information may emerge as further documents and analyses are published.
What to watch next
The key development at this stage is that, according to CNBC, SpaceX’s IPO has reached a total raise of $85.7 billion after the exercise of the greenshoe option. This confirms that the offering hit its expanded size and that underwriters used the tools built into the deal to respond to investor demand.
As more information becomes available, readers can watch for:
- Official filings that detail the final number of shares sold and the role of the greenshoe.
- Additional reporting that corroborates or adds nuance to CNBC’s account.
For now, the central fact is clear in the available evidence: SpaceX’s newly public stock offering has grown materially beyond its base size, with the greenshoe option playing a decisive role in lifting the total raise to $85.7 billion.
