Uday Kotak questions SpaceX’s $147B valuation, warning of a ‘mega bubble’ as Elon Musk’s company sparks debate over tech sector overvaluation. The founder of Kotak Mahindra Bank said the space giant’s IPO, which valued it at $147 billion, risks inflating a speculative frenzy, according to a June 13, 2026, interview. Analysts are now scrutinizing whether the valuation aligns with SpaceX’s revenue projections or reflects broader market euphoria.
The SpaceX IPO, which vaulted Elon Musk into the trillionaire ranks, has reignited debates over tech valuations. Kotak, a prominent figure in Indian finance, argued that the company’s $147 billion valuation—based on a $1.2 billion private round in 2023—may not be grounded in operational metrics. “Capitalism is being tested,” he said, “but only time will tell if we’re in a mega bubble.”
How SpaceX’s Valuation Compares to Sector Peers
SpaceX’s valuation exceeds that of major aerospace firms like Boeing (NYSE: BA) and Lockheed Martin (NYSE: LMT). As of June 2026, Boeing trades at a 12.3x forward P/E, while SpaceX’s private valuation implies a 45x multiple based on 2025 revenue estimates. This disparity has raised questions about whether SpaceX’s growth trajectory justifies such a premium.
SpaceX’s Financials (2025 Estimates)
| Metrics | SpaceX | Boeing | Lockheed Martin |
|---|---|---|---|
| Market Cap (Private) | $147B | $187B | $112B |
| 2025 Revenue | $12.3B | $68.4B | $63.2B |
| 2025 EBITDA | $3.1B | $5.2B | $7.8B |
| Forward P/E | 45x | 12.3x | 10.1x |
“SpaceX’s valuation is a function of its unique position in the space economy,” said
Dr. Emily Zhang, aerospace analyst at Morgan Stanley
. “But the market is pricing in future dominance rather than current earnings. If launch rates or government contracts underperform, the bubble could burst.”
The Ripple Effect on Tech and Venture Capital
SpaceX’s valuation has intensified scrutiny of other high-growth tech firms. Private valuations for companies like Blue Origin and Rocket Lab have also surged, with Blue Origin recently securing a $2.5 billion round at a $30 billion valuation.
“The space sector is becoming a proxy for tech’s broader valuation challenges,” said James Carter, CEO of Silver Lake
. “Investors are chasing growth narratives, but macroeconomic headwinds could force a correction.”
Analysts note that SpaceX’s IPO could influence venture capital funding. A Bloomberg report found that space tech funding rose 15% in Q2 2026, with 62% of deals exceeding $100 million. However, The Wall Street Journal warns that “if interest rates remain elevated, private valuations could face pressure.”
The Macroeconomic Context: Inflation and Interest Rates
SpaceX’s valuation comes amid mixed macroeconomic signals. The U.S. Federal Reserve raised rates by 25 basis points in June 2026, citing persistent inflation.
“Higher borrowing costs could strain SpaceX’s capital-intensive operations,” said Dr. Raj Patel, economist at the New York Federal Reserve
. “While the company’s revenue is growing, its ability to sustain margins depends on supply chain stability and government contracts.”
SpaceX’s reliance on government contracts—particularly NASA’s $1.5 billion Artemis program—adds another layer of risk. A SEC filing in April 2026 noted that 38% of its revenue comes from federal agencies. Any shift in policy could impact its financial outlook.
The Bottom Line
- SpaceX’s $147B valuation far exceeds traditional aerospace peers, raising questions about sustainability.
- Analysts warn that macroeconomic factors like interest rates and inflation could pressure private tech valuations.
- The IPO has amplified debates over whether the space sector is a growth play or a speculative bubble.
As markets digest Kotak’s remarks, the focus will shift to SpaceX’s ability to deliver on its revenue projections. With the Federal Reserve’s policy decisions and geopolitical tensions in the
