Uber is reported to have filed paperwork outlining plans to raise as much as $2.1bn (£1.4bn) in its latest funding round.
Were the company to complete that funding round (and according to the Bloomberg report, the wheels are very much in motion for that to happen - with Tiger Global Management and T Rowe Price both involved), it would be valued at $62.5bn. That's 43.1 billion of our English pounds: higher than the valuation of all but 11 companies in the FTSE 100.
Yep: when Uber closes this round, it'll be worth more than BT, Prudential and Barclays, as well as Unilever and BG Group. Add up the market caps of Aviva and WPP, and you'll have a couple of billion left over.
In fact, the only FTSE 100 constituents it won't be worth more than are Reckitt Benckiser, Diageo, Lloyds, AstraZeneca, Vodafone, Shell, GlaxoSmithKline, SABMiller, BP, British American Tobacco and HSBC.
Uber's valuation has rocketed since it launched just over five years ago: so far it's raised $10bn - $1bn of that in debt, while the rest has been in exchange for equity.
The app is currently available in 80 cities, although it's said it expects to spend $1bn as it expands further into Asia.
