Imagine needing to raise more money than the entire market capitalization of some countries. That’s the reality facing Elon Musk as he prepares to fold his AI company xAI into SpaceX in a $250 billion deal – the most expensive corporate acquisition ever. But Musk isn’t alone in this capital-intensive race. Across Silicon Valley, tech giants are announcing spending plans so massive they’re making Wall Street nervous.
The Muskverse’s Financial Tightrope
According to the Financial Times, Musk’s constellation of companies – what insiders call the “Muskverse” – faces unprecedented financial demands. xAI burns through $1 billion monthly while trailing rivals like OpenAI. Tesla’s car operations have plateaued amid Chinese competition, and SpaceX faces hefty investments despite Starlink’s success. The proposed merger creates a financial vehicle capable of raising the staggering sums needed for Musk’s ambitions: orbital data centers, solar plants, chip fabs, and what he calls “an enormous robot army.”
Big Tech’s $660 Billion Bet
Musk’s move comes amid a broader industry spending spree that’s testing investor patience. As reported by the Financial Times, Amazon, Google, Microsoft, and Meta plan to spend a combined $660 billion on AI infrastructure in 2026 – a 60% increase from 2025. Amazon alone projects $200 billion in capital expenditure, causing its shares to slump 10% despite CEO Andy Jassy citing “seminal opportunities like AI, chips, robotics and low Earth orbit satellites.”
“The capex is breathtaking,” says Jim Tierney, head of concentrated US growth fund at AllianceBernstein. “The onus is on Microsoft and Amazon to prove out the attractive returns on all the spending.”
Investor Skepticism Grows
The market reaction tells a cautionary tale. Following these announcements, the Nasdaq Composite fell more than 3.5% for its worst week in 10 months. “AI bubble fears are settling back in,” notes Brent Thill, analyst at Jefferies. “Investors are in a mini timeout around tech, and nothing the companies say fundamentally matters.”
Fabiana Fedeli, Chief Investment Officer for Equities at M&G, observes: “The market is rethinking its approach to AI. Investors are now a lot more selective in which companies they will decide to bet on.”
The Apple Exception
While most tech giants ramp up spending, Apple takes a different approach. The company saw its stock rise 7.5% as it avoided the AI capex race through partnerships. “Apple’s tiny capex is the AI dividend of partnering with Google for compute and frontier models,” explains Dan Hutcheson, vice-chair of TechInsights. “This shifts Apple’s AI capex to a pay-as-you-go model.”
What’s Really at Stake?
Behind the astronomical numbers lies a fundamental industry shift. Tech companies are betting that high-end computing power will become a scarce, valuable resource – and they’re willing to spend now to secure future dominance. But as Michiel Plakman, head of Global Equity at Robeco, warns: “We are worried in places where we see huge increases in spending but we cannot see what the pay-off is going to be.”
The tension between visionary ambition and financial reality has never been sharper. Musk talks of using space-borne AI to “understand the Universe and extend the light of consciousness to the stars,” while investors demand tangible returns. As these companies pour hundreds of billions into AI infrastructure, one question looms largest: When will the revenue follow the rhetoric?
