1. They want the maximum number of premium matches on TV
The US Open is extraordinarily valuable television inventory. You want Alcaraz, Djokovic, Gauff, Sabalenka etc. in prominent evening slots.
But tennis has an enormous scheduling problem: you dont know whether the preceding match will last 90 minutes or 4½ hours.
So a 7pm match can become an 11pm match, which becomes a 12:30am match.
Venus Williams match starting at 12:13am was the most extreme example this year.
2. They dont want to leave money on the table
Imagine youre ESPN.
At 11pm you have:
US Open Carlos Alcaraz vs X
There are still 700,000 people watching.
You could say:
Sorry everyone, were cutting away because its late.
Or you can keep broadcasting it.
Obviously you keep broadcasting it.
The marginal cost of keeping the television feed running is tiny compared with the value of the rights and advertising.
3. New York is a deliberately late-night sports market
The US Open has embraced the idea that New York is a city that doesnt go to bed early.
Theres a certain cachet to having the night session become a New York sporting event particularly when a big-name player is involved.
The Venus match demonstrated that there can still be thousands of people in the stadium well after midnight. The Guardian reported that several thousand remained for her historic late start.
4. Television doesnt care nearly as much about the empty seats as we do
This is the crucial point.
A television shot showing 70% empty seats looks dreadful to us.
But from ESPNs perspective, if there are 500,000 people at home, the empty seats are basically irrelevant.
But heres the bit I think is commercially questionable
The US Open is effectively optimising for television utilisation rather than the live spectator experience.
And that creates a vicious circle.
You sell a night-session ticket.
You expect:
7pm 11pm-ish
Instead, the first match goes four hours and the second doesnt start until midnight.
People have gone home.
Public transport becomes problematic.
Staff have to work extraordinarily late.
Players are being asked to perform at ridiculous times.
And then you get a half-empty stadium.
Thats not a great product.
Indeed, Venus herself questioned why she was being asked to start at 12:13am, saying she didnt know another sport where you had to start that late.
And theres an even bigger problem
It isnt actually necessary to create these ridiculous starts.
The tournament could simply impose a harder last-start time.
For example:
Night session: two matches, but no new match may start after 11pm.
If the first match runs long, the second match moves to the next available court/day.
That would mean occasionally losing a little television inventory.
And I suspect the real reason they dont do it is that the television rights are worth more than the marginal benefit of protecting the live event experience.
So, in a nutshell:
Are people watching at 1:30am? Some absolutely are particularly hardcore tennis fans and fans of the players involved.
Is the audience still commercially meaningful? Potentially yes, because even a relatively small audience can be valuable when the marginal cost of broadcasting is tiny.
Is a 1:30am start commercially optimal? Id say not really. Its more a consequence of a tournament structure designed around maximising TV inventory and accommodating unpredictable match lengths.
And theres an amusing irony here: the US Open is probably one of the worlds most commercially successful tennis tournaments precisely because it is willing to do things that would be considered completely unacceptable at Wimbledon.
Basically it's a money thing and player and in stadium spectators don't matter in that equation; the winner gets paid ridiculous amounts of money, the last 16 get nearly half a million, so it pays the players. Accept the money and you accept the things that go with it I guess
AI* seems to have missed the critical issue, which is that the US Open wants to charge spectators twice for the same day, nothing to do with TV. To charge twice they need two sessions, and a session with only one match in it is not sufficiently good value to sell the evening session. Starting the second session late is so that people that work during the day (the USofA doesn't seem to have invented holidays yet) can get there.
TV is the jam on top. TV, particularly USofA TV, absolutely hates things that don't run to schedule, so tolerates the variation in finish times rather than encouraging them. At this rate it is not going to be many years before the evening session of the US Open is made up of three fast four matches between some mix of the top 8 seeds and 8 USofA wildcards (including the Williams sisters) because that is all that the US Open thinks the wider public want to see, and they want contests that run to schedule (and that way everyone can get to bed on time). The rest of the matches can play during the day, and they don't care about the format, because only tennis freaks will want to watch them anyway. Mixed doubles was just the start, and they consider it very successful too.
*AI only parrots what it heard elsewhere, and if enough people complain about something online (like "ESPN is ruining the world", "Televising sports will be the death of them" etc.) then that will gain traction with large language models - regardless of the truth if the matter: they really are proof that opinion trumps fact. (... or, somewhat unbelievably, that someone else's opinion is as valid as mine, which is obviously patent nonsense)

I think the two go together - the evening session is wanted by the venue, the French and AO do it as well. But the tv model is vital. We also forget, 1 am is just 10pm on the west coast. Early in the great scheme of things and plenty of people happy to watch on tv. The model serves both commercial aims.
Ps agreed re LLM's - I asked the question "The us open tennis is regularly playing until 1.30/2am each night this year. There are few spectators left. Is anyone watching on TV? What is the point commercially of doing this? " so that maybe influenced the answer I got, driving it towards looking at TV and also ignoring the idea of an evening session, and just focused on the late night finish. So I got the answer aligned to the question I asked!
Without players there's no tournament. I don't have sympathy on the money side but there's been a lot of unrest at the US open this year and the players would be well within their rights to boycott next years event.
Between the stench of weed, the disrespect from the spectators and the ridiculous finish times, I wouldn't be surprised if some started swerving it particularly if they aren't 100% fit.

I don't think the players will choose not to play. The 4 slams dominate their seasons points wise, money wise, profile wise, sponsor wise, legacy wise. They may complain but they won't boycott or swerve it, if they can help it.
