U.S. Senator Elizabeth Warren has called on the Securities and Exchange Commission (SEC) to delay the planned initial public offering (IPO) of billionaire Elon Musk-linked SpaceX, arguing that the offering raises concerns about valuation, shareholder rights, conflicts of interest, and potential risks to millions of retirement savers.
In a letter to SEC Chair Paul Atkins dated June 9, Warren said the agency should conduct additional scrutiny before allowing one of the most anticipated public listings in recent years to proceed.
According to the letter, the IPO’s scale alone warrants close regulatory review. Warren argues that several additional factors, including SpaceX’s governance structure, proposed valuation, and potential index fund inclusion, could expose ordinary investors to significant risks while providing substantial benefits to insiders.
Concerns center on a trillion-dollar valuation
A central focus of Warren’s letter is SpaceX’s reported valuation target of between $1.75 trillion and $2 trillion. The senator argues that the proposed valuation may be difficult to justify based on the company’s current financial performance. SpaceX reportedly generates roughly $19 billion in annual revenue, yet would enter public markets with a market capitalization rivaling some of the world’s largest publicly traded companies.
Warren cited analysts who have questioned the assumptions underlying the valuation and warned that if public investors reject those assumptions after the offering, retail shareholders could face significant losses.
The letter also raises questions about how future growth opportunities, including projects linked to artificial intelligence, satellite services, and long-term space initiatives, are being reflected in the company’s valuation.
Questions raised over the xAI merger
Warren also highlighted SpaceX’s merger with xAI, noting that both companies are controlled by Elon Musk. The senator urged regulators to examine whether the transaction appropriately reflected the value of both businesses and whether related-party considerations were adequately disclosed to investors.
The letter asks the SEC to review whether the merger affected SpaceX’s valuation ahead of the IPO and whether future transactions involving Musk-controlled companies could create additional risks for shareholders.
Governance structure draws scrutiny
Another major issue raised in the letter involves SpaceX’s corporate governance model. According to Warren, Musk would retain substantial control over the company through a dual-class share structure that grants certain shares significantly greater voting power than ordinary stock.
The senator argues that public investors would contribute billions of dollars in capital while having limited influence over major corporate decisions. She also pointed to concerns regarding board independence, executive oversight, and shareholder accountability.
“Publicly traded companies are meant to be accountable to their shareholders,” Warren wrote, arguing that the proposed structure concentrates power in the hands of insiders while limiting investor influence.
Shareholder rights and arbitration concerns
The letter also criticizes provisions that could restrict shareholder remedies. Warren argues that SpaceX’s plans for mandatory arbitration, limitations on shareholder lawsuits, and higher thresholds for shareholder proposals could make it more difficult for investors to challenge management decisions.
She urged the SEC to require stronger investor protections before the company enters public markets, arguing that shareholders should retain meaningful avenues for legal recourse if disputes arise.
Index funds could amplify investor exposure
One of Warren’s most notable concerns involves passive investing. The senator argues that recent changes to index inclusion policies could allow SpaceX to enter major stock market indexes more quickly than companies traditionally have. If that occurs, index funds and retirement accounts tracking those benchmarks could be required to purchase SpaceX shares regardless of valuation concerns.
Warren warned that billions of dollars could flow into the stock through passive investment vehicles, increasing exposure for pension funds, retirement savers, and retail investors who may not have actively chosen to invest in the company. According to estimates cited in the letter, index-related buying could total between $15 billion and $30 billion shortly after inclusion.
Crypto platforms race to offer SpaceX exposure
The debate over investor access to SpaceX has also extended beyond traditional brokerage channels into cryptocurrency markets. In the days leading up to the IPO, several crypto exchanges and trading platforms launched products tied to SpaceX, creating a parallel market around the company before its shares began trading on public exchanges.
The products vary significantly in structure. Platforms such as Kraken and Bybit are offering tokenized IPO-style products linked to SpaceX through the xStocks framework, while other exchanges, including Coinbase, Binance, OKX, Bitget, and Trade.xyz, have listed SpaceX-linked perpetual futures or derivative products that provide exposure to the company’s valuation without ownership of underlying shares.
While these instruments allow investors to gain economic exposure to SpaceX before or shortly after the IPO, none of them provides the same rights as holding ordinary SpaceX shares through a traditional brokerage account.
The emergence of multiple SpaceX-linked products highlights how crypto markets are increasingly competing with traditional financial institutions in providing access to high-profile public offerings. It also adds another layer to concerns raised by Warren, who argues that expanding retail access, whether through conventional investment channels or tokenized products, could increase exposure to a company she believes warrants closer regulatory scrutiny before entering public markets.
Retail investors could face greater risks
The senator also pointed to reports that some asset managers may lower participation thresholds for the offering, potentially broadening access to retail investors. While greater participation could increase public ownership, Warren argues that it could also expose less experienced investors to what she describes as an unusually complex and speculative offering.
The concern, she wrote, is that individual investors may bear a disproportionate share of the downside if the company’s valuation fails to meet market expectations after listing.
SEC asked to investigate additional issues
Beyond valuation and governance, Warren asked the SEC to examine several potential securities-law questions. These include whether information about SpaceX’s confidential IPO filing was improperly disclosed before becoming public, whether public statements by Musk were consistent with official filings, and whether those communications may have influenced investor demand ahead of the offering.
The senator also urged regulators to review disclosures related to conflicts of interest, future mergers, executive control, and financial assumptions used in marketing the IPO.
A call for delay rather than rejection
Warren’s letter does not call for blocking the SpaceX IPO outright. Instead, it asks the SEC to postpone approval until regulators complete additional reviews and require stronger disclosures and investor safeguards.
Her argument is that the combination of a lofty valuation, concentrated insider control, limited shareholder rights, potential conflicts of interest, and broad exposure through index funds creates a set of risks that deserves closer examination before one of the largest IPOs in U.S. history reaches public markets.
