Musk promised biggest-ever SpaceX IPO; now he must deliver

Elon Musk is the boss of a rocket company called SpaceX.

He is very good at telling exciting stories about what his company will do.

Earlier this year, he promised that SpaceX would have a huge stock sale in June.

A stock sale like this is called an IPO.

He said it would be the biggest IPO ever.

At first, that was exciting and fun for people to hear about.

But now the time for talking is over.

Musk has to work very hard to make the company do everything he promised.

The article says this part is much harder than selling the dream.

Now he has to hold on and prove that his big promises can come true.
