The chart of the week ranks the world’s biggest IPOs by deal size and shows a dramatic gap between the top entry and the rest. The much-anticipated SpaceX IPO is listed as the largest potential IPO, with an estimated deal size of $75 billion expected in June 2026. This projected amount is almost three times larger than the IPO of Saudi Aramco, which raised $25.6 billion in 2019. The chart also highlights the dominance of technology and communication companies, including Alibaba and Meta. If the SpaceX IPO happens at the estimated value, it could become the largest public offering in history by a very wide margin. The recent market environment has been beneficial to IPOs and should the SpaceX IPO be a success, it could lead to further initial public offerings.
