HFT have installed microwave relays between Chicago and New York and between London and Berlin to arbitrage on the 47% fiber optic delay between the exchanges. A LEO satellite relay serves the same purpose. I can see London to New York, New York to Tokyo fiber connections being superceded by LEO satellite.

If you mean Deutsche Börse AG, than that would be Frankfurt am Main and not Berlin which is a slight difference of about 400 km. Frankfurt to London is actually a shorter distance. https://en.wikipedia.org/wiki/List_of_stock_exchanges

Quite surprised why LEO for cross exchange arbitrage was not already done. Microwaves were not super with weather conditions the last time taking an arbitrary interest.

LEO sat constellations that are low enough to beat existing solutions need to be almost global to provide reliable communication anywhere.
