The mining magnate\u2019s friendship with Musk has evolved via their mutual support of Donald Trump<\/a> during the 2024 US presidential election<\/a>. Rinehart has described Musk as a \u201ctruly exceptional person\u201d.<\/p>\n It has not, however, been one of Rinehart\u2019s better investments, as SpaceX was floated at $US135 a share, peaked at $US201.80 in the days following the listing, but has traded as low as<\/a> $US108 a share in recent weeks. It ended trading on Friday at $US140 a share.<\/p>\n Related Article The filing reveals that Rinehart also bought almost 600,000 SpaceX shares after the float, to take her stake to 8 million shares. The SpaceX float briefly made Musk the world\u2019s first trillionaire<\/a>. Rinehart\u2019s stake in the rocket, artificial intelligence and satellite company is the single largest investment outside iron ore made by her private company Hancock Prospecting.<\/p>\n Rinehart topped the 2026 Financial Review Rich List, with an estimated wealth of $39 billion.<\/p>\n Her bet on Musk does not end with SpaceX. The latest disclosures reveal she retains almost 21,000 shares in Musk\u2019s electric carmaker, Tesla. Rinehart\u2019s stake there is worth just under $US9 million, and the market is now mooting that Musk\u2019s next strategic move will be to merge SpaceX and Tesla into one company.<\/p>\n The quarterly filing to the United States Securities and Exchange Commission reveals Rinehart has also boosted her support for Trump, doubling her investment in the listed Trump Media and Technology, which owns the president\u2019s Truth Social platform<\/a>.<\/p>\n Rinehart now has 870,000 shares in the company, compared with 430,000 at the end of March, and her stake is now worth $US6.7 million.<\/p>\n Along with her relationship with Musk and support for Trump, closer to home, Rinehart has emerged as a major financial backer of Pauline Hanson\u2019s One Nation.<\/p>\n In April, Hanson confirmed Rinehart had bought One Nation a light plane<\/a> to facilitate campaigning. The Queensland senator and the billionaire were recently photographed together poolside at a luxury resort in Sicily on a trip that Rinehart partially funded<\/a>.<\/p>\n The filings overnight show Rinehart also has stakes in other US-listed tech companies including semiconductor giant Nvidia, the Jeff Bezos-controlled Amazon, Google\u2019s owner Alphabet, and Microsoft. She also has shares in the Murdoch-family controlled Fox Corp, which is chaired by Lachlan Murdoch.<\/p>\n Rinehart has also made a major $US832 million bet on rare earths miner MP Materials<\/a> and has $US612 million invested in Canadian natural resources company Teck Resources.<\/p>\n Hancock Prospecting was contacted for comment.<\/p>\n Start the day with a summary of the day\u2019s most important and interesting stories, analysis and insights.
