Summary
John Arnold built his fortune in energy trading by surrounding himself with smart people, maintaining emotional detachment, sensing market imbalances through first-principles analysis, and focusing with laser intensity on a single niche until he dominated it completely. Now he's applying that same analytical rigor to philanthropy, where he's discovered that changing human behavior for the long term proves far more challenging than predicting natural gas prices, and that the academic research meant to guide social policy is often riddled with perverse incentives and poor methodology.
Tyler and John discuss his shift from trading to philanthropy and more, including the specific traits that separate great traders from good ones, the tradeoffs of following an "inch wide, mile deep" trading philosophy, why he attended Vanderbilt, the talent culture at Enron, the growth in solar, the problem with Mexico’s energy system, where Canada’s energy exports will go, the hurdles to next-gen nuclear, how to fix America’s tripartite energy grid, how we’ll power new data centers, what’s best about living in Houston, his approach to collecting art, why trading’s easier than philanthropy, how he’d fix tax the US tax code and primary system, and what Arnold Ventures is focusing on next.

| 0:23.4 | Hello everyone and welcome back to Conversations with Tyler. Today I'm here with John |
| 0:31.4 | Arnold. John is arguably the greatest energy trader in all of world history. In 2007, he became known as America's |
| 0:39.9 | youngest billionaire. These days, working with his wife, Laura, he does Arnold Ventures, |
| 0:45.3 | where we're sitting right now, and Arnold Ventures is one of the most important and influential voices |
| 0:50.5 | and actors in philanthropy. John has done much more. That's just a brief outline. John, welcome. |
| 0:56.7 | Thank you for that intro and great to be here. Your days as an energy trader. Do you think you |
| 1:02.0 | were especially good at trading at the close or you didn't like doing that? There was always an |
| 1:08.2 | imbalance on the close. And so if you could sense what it was, whether it was imbalance for buyers or |
| 1:13.8 | imbalance for sellers, it definitely offered an opportunity. |
| 1:16.0 | And the close kind of set the index for the day as to the starting point for the next day. |
| 1:23.3 | So it was particularly important, but I don't think there was anything necessarily |
| 1:27.1 | profitable about it besides a little bit around the edges. Okay. So it was particularly important, but I don't think there was anything necessarily profitable |
| 1:28.5 | about it besides a little bit around the edges. |
| 1:31.4 | But sensing that imbalance, what do you feel is the skill you had that your other traders |
| 1:36.2 | didn't have to the same degree? |
| 1:37.8 | Yeah, I've always had a difficult time answering this question. |
| 1:40.3 | I think, you know, part of it is trading is a team sport for sure. |
