SpaceX's imminent market debut is driving unprecedented attention toward space-themed ETFs, with the company planning to raise $75 billion by selling 555.6 million shares at $135 per share, valuing the business at $1.8 trillion. Investor orders have reportedly topped $250 billion, making the IPO nearly 4x oversubscribed. According to latest reports, three ETFs marketing pre-IPO SpaceX exposure attracted a combined $4.12 billion in inflows in May, followed by another $645 million during the first five trading days of June. The ETF rush includes new launches from BlackRock with the iShares Space Technologies UCITS ETF (STAR), which holds 56 stocks with RKLB making up about 20% of the portfolio, and ProShares unveiling the ProShares Ultra SpaceX ETF (SPCF), which seeks to deliver 2x the daily performance of SpaceX shares.
Polymarket traders have assigned just 18% probability that Tesla and SpaceX will officially announce a merger before the end of 2026, despite months of speculation about the two companies. According to reports from Polymarket, the December 31 contract trades around 18 cents, while the September 30 contract sits at roughly 5%, suggesting almost no chance of an imminent announcement. The nearer-term outlook appears even more pessimistic, with activity across relevant contracts exceeding $1 million, indicating genuine trader interest despite the low probabilities. With only about 7% of SpaceX shares expected to be freely tradable initially, competition for exposure has been intense among investors seeking direct access to the space company.
CEO Elon Musk has highlighted memory chips as the biggest bottleneck in building AI infrastructure, stating that memory demand is growing 200% year-over-year, potentially higher, while supply increases by only 20% annually. Speaking on SpaceX's post-earnings analyst call, Musk explained that this supply-demand imbalance naturally positions for sharp price increases. Musk's companies own significant AI infrastructure, with Tesla's Cortex supercomputer at Gigafactory Texas and SpaceX's Colossus facility in Memphis, which has scaled to 200,000 Nvidia H100 GPUs with plans to reach 1 million GPUs. The CEO outlined plans to expand AI data center capacity to as much as 10 gigawatts by 2027.
Recent financial results from SpaceX have contributed to market caution, as reported by Polymarket. The company's first public earnings report following its June 2026 IPO showed revenue of $7.8 billion, up 92% year-over-year, while the company narrowed its net loss. However, capital expenditures topped $18 billion in the quarter, largely directed toward artificial intelligence infrastructure. The market reaction was swift, with shares falling roughly 8% to 11% as investors digested the heavy spending plans alongside an impending lockup expiration. The company's IPO plans to raise $75 billion by selling 555.6 million shares at $135 per share reflect the massive capital requirements for its AI and space infrastructure ambitions.
Despite the low odds, business convergence continues between the two companies, with shared ambitions spanning artificial intelligence, robotics including Optimus, autonomous driving data, and potential space-based data centers. According to Polymarket analysis, analysts have floated ambitious numbers, with valuations for a combined entity potentially approaching or exceeding $5 trillion according to some projections. The operational overlap among Elon Musk's flagship firms continues to grow, yet market skepticism remains deep. The space ETF boom, with $8 billion in net inflows this year making it one of the fastest-growing ETF categories, reflects growing investor appetite for companies like SpaceX and related space infrastructure stocks.
A significant obstacle to any merger involves Tesla's potential separation from its China operations, as reported by Polymarket. The Wall Street Journal detailed internal discussions where executives reportedly explored a spin-off, sale, or structural separation of the Shanghai operations. The geopolitical logic is straightforward, as SpaceX serves as a key US defense contractor, making any combination with a company deeply embedded in China politically sensitive. Musk has forcefully rejected these reports, dismissing them as 'absurdly fake news' and insisting the topic had never been discussed internally, though China remains commercially significant for Tesla as the second-largest market.
