I'd say IEX has done remarkably well - it's not likely to displace NASDAQ or NYSE but it has solidified its place as the #3 US exchange by any reasonable measure. If TXSE achieves comparable market share I'd call that a wild success.

You're not wrong to say that most participants don't care about what IEX offers, but enough do to make a meaningful dent in trading volume.

It’s definitely not 3rd place. That’s cboe and it’s not close. It’s hanging around with ~2% of the trade volume.

I don’t know if that is “remarkably well” but it certainly isn’t some market paradigm shift.

If you were to tell me in 10 years the Texas exchange would have 2% of the market I’d believe you. But I’d still not be terribly impressed.
