In the span of a single quarter, Australia's wealthiest person, Gina Rinehart, has nearly doubled her American holdings to $5.7 billion, anchoring the expansion in a billion-dollar bet on Elon Musk's SpaceX and deepening her stake in Donald Trump's media company. The moves are more than financial manoeuvres — they trace the contours of a worldview, one in which capital, political sympathy, and personal allegiance are deployed together as instruments of influence. Rinehart's portfolio is, in this sense, a kind of autobiography written in securities filings.
Rinehart doubles US portfolio to $8B with major SpaceX, Trump Media bets
She's betting that Musk and Trump represent the future
Mark
Why does someone with $39 billion in wealth need to double down on US stocks? Isn't she already diversified enough?
Mimi
Diversification isn't really the story here. She's concentrating, not spreading risk. This is about conviction—she's betting that Musk and Trump represent the future, and she's willing to put serious capital behind that belief.
Mark
But SpaceX has already lost money for her. It peaked at $201 and now trades at $140. That's not a great return in three months.
Mimi
True, but she bought more shares after the float, not fewer. That tells you she's not trading it—she's holding it as a long-term position. The volatility doesn't seem to concern her. She's thinking bigger than quarterly returns.
Mark
What about the Trump Media investment? That seems like a riskier bet than SpaceX.
Mimi
It's smaller in absolute terms, but she doubled it. That's a signal of confidence, or at least alignment. Trump Media is illiquid and speculative, but she's willing to hold it. It's not about the financial return—it's about being inside the circle.
Mark
Is there a political dimension to all this that matters?
Mimi
Absolutely. She's funding One Nation, she's close to Musk, she's backing Trump. This isn't just portfolio management—it's political positioning. Her money is becoming a form of influence.
Mark
What happens if Musk and Trump's fortunes diverge?
Mimi
Then she loses a lot of money. But that's not the bet she's making. She's betting they stay aligned and that their ventures—space, energy, social media—become increasingly central to the economy. It's a high-conviction play.
Der Puls
- A single $1 billion SpaceX purchase — volatile from the moment of its Nasdaq debut, swinging between $108 and $201.80 — now anchors Rinehart's largest investment outside her iron ore empire.
- Her Trump Media stake has doubled to 870,000 shares in just three months, a move that reads less as a financial calculation than as a public declaration of political alignment.
- Wall Street speculation that Musk may merge SpaceX and Tesla has placed Rinehart at the centre of a potential reshaping of two of the world's most watched companies.
- Beyond Musk and Trump, her portfolio spans Nvidia, Amazon, Alphabet, Microsoft, rare earths, and Canadian resources — a diversification that softens, but does not conceal, the ideological concentration at its core.
- Back in Australia, Rinehart has funded a campaign plane for Pauline Hanson's One Nation party and shared a Sicilian resort holiday with Hanson — a pattern suggesting her wealth is being deployed to shape political landscapes on both sides of the Pacific.
In the span of a single quarter, Australia's wealthiest person, Gina Rinehart, has nearly doubled her American holdings to $5.7 billion, anchoring the expansion in a billion-dollar bet on Elon Musk's SpaceX and deepening her stake in Donald Trump's media company. The moves are more than financial manoeuvres — they trace the contours of a worldview, one in which capital, political sympathy, and personal allegiance are deployed together as instruments of influence. Rinehart's portfolio is, in this sense, a kind of autobiography written in securities filings.
Australia's richest person, Gina Rinehart, has nearly doubled her US stock portfolio in three months, with securities filings showing her holdings growing from $3.3 billion in March to $5.7 billion by late June. The expansion was driven by a single defining move: a $1 billion investment in SpaceX during its June Nasdaq listing, acquiring around 7.4 million shares at $135 each. She later added 600,000 more, bringing her total to 8 million shares now valued at $1.4 billion — her largest investment outside the iron ore business that built her Hancock Prospecting empire.
The SpaceX bet has been turbulent. The stock surged to $201.80 shortly after listing before falling as low as $108, settling near $140 by Friday. The volatility has not dimmed Rinehart's enthusiasm for Musk's orbit. She also holds nearly 21,000 Tesla shares and has publicly praised Musk as a "truly exceptional person." Both backed Donald Trump in 2024, and that alignment is visible in her portfolio: she doubled her Trump Media stake from 430,000 to 870,000 shares, now worth $6.7 million.
The broader portfolio reflects a technology tilt — Nvidia, Amazon, Alphabet, and Microsoft all feature — alongside $832 million in rare earths miner MP Materials and $612 million in Canadian resources company Teck Resources. Yet the concentration in Musk-linked and Trump-aligned assets suggests something beyond diversification: a deliberate use of capital to back figures she regards as consequential.
Markets are watching closely. Rinehart topped the 2026 Financial Review Rich List with an estimated net worth of $39 billion, and her investment decisions carry signal value. Speculation is already circulating that Musk could merge SpaceX and Tesla, a move that would reshape both companies and potentially amplify the value of her combined stake. Meanwhile, at home, she has funded a campaign aircraft for Pauline Hanson's One Nation party and was recently photographed with Hanson at a Sicilian resort she partly funded — a reminder that Rinehart's ambitions extend well beyond the balance sheet.
Australia's wealthiest person, Gina Rinehart, has nearly doubled the value of her American stock holdings in the span of three months. Securities filings released overnight show her US portfolio swelling from $3.3 billion at the end of March to $5.7 billion by late June—a jump of more than $2 billion that reflects a calculated shift toward technology and politically aligned ventures.
The growth was anchored by a single, substantial bet: Rinehart deployed $1 billion into SpaceX during its June listing on Nasdaq, acquiring approximately 7.4 million shares at $135 per share. The investment has proven volatile. The stock climbed to $201.80 in the days after the float, then retreated, trading as low as $108 in recent weeks before settling at $140 by Friday. Despite the fluctuation, her stake in Elon Musk's rocket, satellite, and artificial intelligence company now sits at $1.4 billion and represents her single largest investment outside iron ore—the foundation of her Hancock Prospecting empire. She added another 600,000 shares after the initial offering, bringing her total holding to 8 million shares.
The SpaceX investment is not Rinehart's only exposure to Musk. She maintains nearly 21,000 shares in Tesla worth just under $9 million. The two billionaires have cultivated a relationship rooted partly in shared political sympathies. Both backed Donald Trump during the 2024 presidential election, and Rinehart has publicly described Musk as a "truly exceptional person." That alignment extends to Trump himself. Rinehart has doubled her stake in Trump Media and Technology, the company that operates the president's Truth Social platform, from 430,000 shares in March to 870,000 shares by June. Her position is now valued at $6.7 million.
Beyond these headline investments, Rinehart's portfolio reveals a broader technology tilt. She holds stakes in Nvidia, Amazon, Alphabet, and Microsoft. She has also committed $832 million to rare earths miner MP Materials and $612 million to Canadian natural resources company Teck Resources. The diversification suggests a calculated strategy, yet the concentration in Musk-controlled entities and Trump-aligned companies signals something deeper: a deliberate alignment of capital with political and business figures she views as consequential.
The timing and scale of these moves carry weight in financial markets. Rinehart topped the 2026 Financial Review Rich List with an estimated net worth of $39 billion. Her decisions move markets and signal confidence. Wall Street is already speculating that Musk's next strategic move could be a merger of SpaceX and Tesla, which would dramatically reshape both companies and potentially amplify the value of Rinehart's combined stake.
Closer to home, Rinehart has emerged as a major financial backer of Pauline Hanson's One Nation party. In April, Hanson confirmed that Rinehart had purchased a light plane for the party to use in campaigning. The two were recently photographed together poolside at a luxury resort in Sicily during a trip that Rinehart partially funded. These moves paint a picture of a billionaire using her wealth not merely to accumulate returns, but to shape the political and business landscape according to her vision.
