It's a sweltering day here in New York City, and that means Wall Street is on fire, and so is Robinhood, apparently. The popular stock trading app officially filed its Form S-1 with the SEC a few hours ago to go public, where it will trade under the ticker "HOOD."

The Equity crew has been yammering about Robinhood for years now, and we have been chomping on the bit to see those S-1 results for what feels like ages. Well, we finally got the numbers, we chomped that bit (or at least Alex and Danny did, since Natasha went on vacation about 15 minutes before the IPO hit the wires), and so here's a special Equity Shot to talk about all the highlights.

We talked about so much in an itsy-bitsy 15-minute episode: crazy revenue growth, crazy revenue concentration from two major sources, regulatory hurdles that the company has been clearing up, better financials with a bit of nuance on the company's Q1 finances, and the company's special plan for its IPO.

Wowza.

Here's what we got up to:

Historical growth and profitability.
Revenue mix and revenue concentration, along with constituent concerns.
The importance of options-related incomes for the company.
Dogecoin.
Why the company's adjusted income may help it assuage investors who have their eyes pop out of their skulls when they see its GAAP Q1 2021 results.

And a lot more. Of course, if you hate Robinhood, we will be back with our normally-scheduled Friday episode of Equity tomorrow.
