Enron was absolute peanuts compared to the financial fraud Musk has been executing (with the apparent blessing of the SEC). At its peak Enron had a roughly $70B market cap, TSLA is currently sitting at $1.74T. We can expect similar numbers from the SpaceX IPO.
It's hard to compare these numbers directly since valuations have increased quite a bit since a quarter century ago. As a proportion of the S&P 500, Tesla (2.3%) is about 4x of Enron at that $70b (0.6%).
