SpaceX Stock Climbs as Nasdaq-100 Inclusion Forces Billions in Buying

SpaceX (SPCX) shares climbed 7.15% to $164.19 over 24 hours ahead of the company’s forced entry into the Nasdaq-100 index on July 7. Nasdaq confirmed the aerospace and AI company will be added to the benchmark after the close on July 6, with index-tracking funds required to begin buying the next morning. The rebalance is mechanical, with index funds required to hold the stock once it sits inside the benchmark.

Bank estimates put the passive demand in the single-digit billions. J.P. Morgan’s $4.3 billion passive inflow estimate for the Nasdaq-100 sits above Jefferies’s $3 billion sizing for the Russell index. The mood in fixed income is colder. Allianz chief investment officer Ludovic Subran described the bond deal at the FT Global Insurance Summit as a sign markets have entered bubble territory. Citadel Securities, in a note circulated to clients this week, warned the AI rally faces weaker demand, falling returns and regulatory scrutiny just as the Federal Reserve edges closer to a rate-hike cycle.

The Forced Trade Setting the Price Floor

Index inclusion is mechanical, not optional. When a company joins the Nasdaq-100, every ETF and mutual fund that tracks the benchmark has to hold it. That obligation converts the addition into mandatory buying across every tracking fund. The price impact of the addition concentrates in the first hours of trading on July 7.

SpaceX will occupy a narrow slice of the index. Nasdaq set the inclusion weighting at less than 1% of the benchmark. Two banks have sized the demand for the addition.

The buy obligation lands on a thin float. With the company carrying roughly $2 trillion in market capitalization against only about $100 billion of publicly traded shares, the forced buying hits a fraction of the available paper. Morningstar chief equity market strategist Michael Field said the fast-tracked inclusion highlights investor interest, then added his firm believes SpaceX is overvalued. SpaceX posted a net loss of $4.9 billion in its most recent fiscal year. SpaceX joining the Nasdaq-100 as bond traders warn ties the equity buy to the credit signal on the same name.

Bond Traders Are Saying No

Credit markets have priced in more risk than the equity market for the same company. SpaceX’s 5.35% bonds were trading last Friday at a spread of 112 basis points over risk-free rates, versus 106 basis points two days earlier, per SpaceX bonds weakening as investors demand more spread. The bonds sat among the most actively traded U.S. investment-grade paper.

SpaceX marketed $20 billion of senior unsecured notes on June 22 and upsized the sale to $25 billion after demand reached roughly $90 billion in orders, one of the five largest peak order books of 2026 in the U.S. investment-grade market. The notes carry investment-grade ratings and run across five tranches from 2031 to 2056 maturities. Proceeds are earmarked for refinancing bridge debt and supporting AI infrastructure tied to the company’s xAI merger. Allianz CIO Ludovic Subran, speaking at the FT Global Insurance Summit, described the bond deal as a sign markets have entered bubble territory, per Ludovic Subran’s bubble territory warning. The bond sale priced in the same week as SpaceX’s $75 billion IPO.

$70 billion of funny money.

SpaceX disclosed approximately $100.8 billion in cash as of June 19, the same window it asked bond investors for $25 billion more. The company took a $2.59 billion operational loss in 2025 and warned in its IPO prospectus that it cannot predict when it will achieve profitability.

The longer-dated bonds drew the heaviest selling. Three of the ten most actively traded U.S. investment-grade bonds on Friday were SpaceX paper, with volumes eclipsing Nvidia, Meta, and several large banks. Spreads gapped out further on the longest maturities, with the 30-year tranche widening by about 30 basis points in its first week. Mike Sanders, head of fixed income at Madison Investments, called the move ‘a pretty big move.’ The full SpaceX issuance carried investment-grade ratings across five tranches running from 2031 to 2056 maturities.

Citadel Maps the Risk to Dot-Com and 1970s

Citadel Securities circulated a note to clients on Monday arguing that investors are underestimating the Federal Reserve’s resolve to control inflation. The trading firm said the central bank may need to pivot toward rate hikes if inflation persists. The note pointed to weaker AI demand, falling returns on AI investments, and rising political and regulatory scrutiny as catalysts most likely to puncture the AI rally. Nohshad Shah, head of EMEA fixed-income sales at the firm, drew an explicit parallel, per Citadel’s Nohshad Shah comparing the backdrop to dot-com and 1970s: ‘The current market backdrop resembles a combination of the dot-com boom at the turn of the century and the oil-driven inflation shock of the 1970s.’

Shah said the Fed could raise rates as soon as September if oil prices and inflation stay elevated. SPCX rose ahead of index-fund positioning for July 7 inclusion, while broader tech names with longer AI exposure ended weaker. Reports that OpenAI is considering price cuts for its AI services, cited in the Citadel note, sharpened the concern that customers are becoming more sensitive to AI costs. The note pointed to still-elevated oil prices as a separate headwind for the rate path. Shah wrote that AI-linked valuations could face pressure if revenue growth disappoints while oil prices and higher interest rates tighten financial conditions.

• The note was issued Tuesday and circulated to clients this week
• Shah drew on colleague Frank Flight’s research on AI economics
• The US-Iran Strait of Hormuz deal eased some macro pressure Monday
• ‘Tightening episodes have a long history of taking the wind out of large equity bull markets’
• ‘The market is too complacent about inflation’

SpaceX priced the largest AI debt deal of 2026 at $25 billion. Nasdaq-100 inclusion will push the equity into more institutional mandates. The equity buy lands on the same calendar as the Fed rate-hike window Citadel flagged.

Eighteen Days of Volatility Between the High and the Low

Eighteen trading sessions separate SpaceX’s Nasdaq debut from its July 7 inclusion. SPCX swung from a record high to a record low inside a single week. Shares had slid 16.4% last week alone after KeyBanc adopted a more cautious stance on the name. The company has yet to file its first quarterly earnings report as a public company.

1. June 12: SpaceX IPOs on Nasdaq at $135 per share, opens around $150
2. June 15: SPCX up more than 1% in Monday premarket trading after first full day
3. June 16: SPCX hits all-time high of $225.64
4. June 22: SpaceX launches $20 billion bond sale, upsized to $25 billion the next day
5. June 23: SPCX hits all-time low of $147.11
6. June 26: SpaceX 5.35% bonds trading at 112 bps over Treasuries, versus 106 bps two days earlier
7. June 30: SPCX up 7.15% to $164.19 ahead of July 7 inclusion

Six analysts currently rate SPCX a Buy, while CFRA is the only firm with a Sell. KeyBanc initiated coverage with a Sector Weight last week. KeyBanc described SpaceX as ‘the dominant leader in space launch and space-adjacent verticals’ but said the current risk-reward profile appears balanced until there is greater clarity on the development of the company’s next-generation Starship rocket.

How Much of the AI Trade Hangs on SpaceX

OpenAI and Anthropic are each expected to pursue IPOs over the next two years, with both potentially targeting valuations exceeding $1 trillion, Reuters reported. The combined demand for those paper floats will run through the same passive-fund plumbing now absorbing SpaceX. The composition of the Nasdaq-100 will rotate as those names join. Baird told clients that the strategic rationale for a Tesla-SpaceX combination is clear, and limited end-market overlap should keep regulatory scrutiny light. SpaceX’s IPO priced at $135 per share, valuing the company at roughly $2 trillion at its debut.

S&P Global will not relax its index eligibility rules for SpaceX. The company will not be considered for inclusion in the S&P 500 until it has traded publicly for at least 12 months.

The forced buying starts July 7. The bond widening is already underway, with three of the ten most actively traded U.S. investment-grade bonds on Friday coming from SpaceX. The Nasdaq-100 rebalance and the next round of bond trading both fall in the first week of July.

Frequently Asked Questions

When will SpaceX join the Nasdaq-100?

SpaceX will be added to the Nasdaq-100 after the close of trading on July 6, 2026, with index-tracking funds required to begin buying the next morning. Nasdaq confirmed the date in late June, citing the easing of several eligibility rules covering profitability, time since IPO, and public float.

How much passive buying will the inclusion trigger?

J.P. Morgan estimated about $4.3 billion in Nasdaq-100 inflows for SpaceX in a note circulated Friday. Jefferies sized the parallel Russell index demand at nearly $3 billion. The estimates reflect the company’s roughly $2 trillion market capitalization against about $100 billion of publicly traded shares.

Why are SpaceX bonds falling while the stock rallies?

SpaceX’s 5.35% bonds were trading last Friday at a spread of 112 basis points over Treasuries, versus 106 basis points two days earlier, and the 30-year tranche had widened by about 30 basis points in its first week. Investors are demanding more compensation to hold long-dated AI debt, even as index mechanics lift the equity.

What did Citadel Securities warn about?

Citadel argued the Federal Reserve could raise rates as soon as September if inflation stays elevated. The note, which drew on colleague Frank Flight’s research on AI economics, framed the current backdrop as a hybrid of the dot-com boom and the 1970s oil shock. Citadel also flagged softer AI demand, falling returns, and regulatory scrutiny as threats to AI-linked valuations.

Will SpaceX join the S&P 500 too?

Not soon. S&P Global said it will not relax its index eligibility rules for SpaceX. The company will not be considered for S&P 500 inclusion until it has traded publicly for at least 12 months.
