Latency to where? One of the promises of starlink is reducing latency over mid distance - say transatlantic or even across the states, due to using vacuum rather than fibres. Will be interesting how HFT use it. Starlink network is nowhere near complete so I’d expect things to only get better (until customers start piling on)

Why would HFT even consider using it? They are located as close as possible to the exchange they operate on, not across states or halfway across the world.

Arbitrage between multiple exchanges requires data to go from exchange A to exchange B as fast as possible.

Light in vacuum is faster than light in fiber.

But if you can access to information from an exchange halfway across the world faster than others, you can definitely trade on that.

Speed is variable, capacity can be improved. The bigger question re Starlink is latency, which this test doesn't show.

They need sat-sat links for that, I think the current generation of starlink doesn't have that so initial customers will not see that kind of benefit, their data will be bounced back to a ground station from the same satellite.

Same stock is listed in more than one place, and also e.g. stock movements in NY affect stocks in London. There are undersea cables built for this purpose: https://www.popularmechanics.com/technology/infrastructure/a...

They make trades at one exchange based of prices at another. For that reason there has been a lot of microwave relays set up between New York and Chicago, for example. Starlink could reduce latency from New York to London, another important center of trade.

I'd assume latency from endpoint to satellite back to terrestrial base station.

I can get satellite Internet right now with 40Mbps down / 5 up, but the latency is 800 to 1000 ms, so it's slow.

This is amazing. I know there will be latency issues, but for majority of web browsing, videos, etc, it shouldn't matter. We are entering the era of spacenet and the future looks bright. Imagine having devices as small as phones or set-top boxes that can directly access internet using satellites. It would lead to a revolution in many industries.

Could you expand on which industries will be improved? My normal life is covered entirely by 4G, with 5G now appearing.

I guess you mean things like internet on planes, shipping internet, off-shore rigs? But what things can't they do at the moment because of prohibitorily slow/costly satellite internet?
