The Plumbers Always Get Paid
We need to zoom out, because this deal does not exist in a vacuum. It is merely the latest chapter in a long, predictable story of exchange consolidation.
Look at the London Stock Exchange Group buying Refinitiv a few years ago. Look at their subsequent partnership with Microsoft to layer artificial intelligence over financial data.

The real power, and the truly unassailable profit margins, lie in proprietary data and workflow software.
Trading networks are incredibly sticky. Once a global asset manager plugs their entire daily operation into your system, tearing it out is like trying to remove Japanese knotweed from a country garden. It is virtually impossible. The more participants on the network, the better the liquidity, and the harder it is for anyone to leave.
This brings me to a fascinating quirk of market psychology. You will often see the retail crowd obsessively chasing the shiny new things, throwing cash at tech startups and Capitalizing on the IPO Boom when the market runs hot.

Tradeweb operates in a very similar space to MarketAxess and has its own fiercely loyal client base. I suspect their management team has been fielding a few interesting phone calls this week.
