As interfaces move to AI platforms, I was trying to figure out which market data providers have the most proprietary value. I think this may be part of the challenge they are facing.
MSCI = Benchmark/risk models
LSEG = Exchange, RT
S&P = Ratings, Benchmark
Moodys = ratings
Morningtar = stars
BBG = FI content
FactSet = cusip
Besides cusip, is there a proprietary data/analytics set that Factset provides in this new world.
