Will be interesting if Uber or Lyft will postpone IPO in favor or buying one of them. Cant imagine it's possible to acquire one of them and still IPO in near future - but who knows. Exciting to see scooters and bikes get nice adoption! Changing the form factor to be more like a mini car (with at least a seat) would be neat, scooters just dont feel that safe.
Uber is on track to run out of money in 2019, so a financial event is inmminent. I don't know if we will see an Uber 2019 IPO, but if it doesn't happen is more likely due to the current bear market and not so much because they are considering a large acquisition.
If they acquire a scooter company I presume they will do it through a mix of debt and a heavy stock component. In fact it seems that they already raised another 2 billion through private placement bonds.
