From another billionaire blasting off, to a gift for the man who has everything, this is the Week in Numbers. First up...

$50 million is how much you get to just stick around... if you're Jamie Dimon. The JP Morgan boss was given stock options worth around that much this week, to incentivise him to stay on for a 'significant numbers of years'. Since he already has a net worth measured in the billions, some wondered whether a mere 50 million would actually be all that incentivising.

66.5 miles is how high Jeff Bezos got off the ground this week.

"Oh my God! My expectations were high and they were dramatically exceeded."

The Amazon founder soared into space with three others on one of his own Blue Origin rockets. Bezos says it's not just about fun for him, but is the start of a new business. He says Blue Origin has close to $100 million in bookings for future flights.

Up to $35 billion is the target valuation for Robinhood Markets. That sets the stage for one of the most highly anticipated stock market listings this year. Between 20 to 35% of the shares will be reserved for users of the trading app, which has been at the centre of this year's meme-stock mayhem.

$3.2 billion is the price for some luxury Italian menswear. Or at least it's the value put on Ermenegildo Zegna in a deal to list in New York. The brand known for 'sheep to shop' clothing production will combine with a U.S. investment vehicle, though the Zegna family will keep a majority stake.

And 65% was the first-day gain for shares in Zomato. It marks a stellar first listing in India for a local unicorn - that's a startup valued at over a billion dollars. Now analysts say the food-delivery app's big debut could open the floodgates for many more Indian deals.
