how did preston clyburn make his money in the madison

I couldn’t verify any public source that explains exactly how Preston Clyburn made his money in The Madison. The coverage I found only says he had a “live-large income” from a business he disliked, and that the family lived an affluent New York lifestyle before moving to Montana.

What’s confirmed

• Preston Clyburn is portrayed as the wealthy patriarch of the Clyburn family in The Madison.

• He lived and worked in New York City and frequently traveled to Montana.

• Public articles do not spell out his exact industry or business model.

Best read on it

From the available descriptions, the safest answer is that Preston made his money through some unspecified New York business activity rather than through anything tied directly to Montana. If you want, I can also give you a quick character breakdown of Preston and the Clyburn family as shown in the series.
