First up on this week’s episode of Inside Business is Elon Musk‘s company SpaceX and its plan to raise $75 billion through what will likely be the biggest initial public offering (IPO) in history this Friday.The company values itself at $1.75tn, but some analysts feel it is worth far less.Could it prove to be a risky bet for the retail investor given SpaceX’s lack of profit? And there are question marks over governance given Musk’s almost untouchable status within the company.To get some insight on all this, host Cliff Taylor was joined in studio by Aidan Donnelly, head of Global Equities at Davy.Plus, European Central Bank President Christine Lagarde is expected to announce a 0.25% rise in the ECB’s interest rate, this will bring it up to 2.25%.It will be the first interest rate hike since 2023, following Russia’s invasion of Ukraine and the impact that had on energy prices.So, what does this week’s increase mean for Irish mortgage holders and those looking to buy?And is this the beginning of a cycle of increases designed to control rising inflation?Cliff was joined in studio by Senior Mortgage Advisor at Irish Mortgage Brokers, Michael Dowling.Produced by John Casey with JJ Vernon on sound.
