| Hey, everyone. Love it or hate it, WeWork was no doubt the story of the week. The $47 billion coworking company filed to go public Wednesday, providing the first in-depth look at its financials and starting the countdown to one of the most highly anticipated — and possibly most scrutinized — market debuts of the year. In the filing, WeWork revealed billions in losses, a sprawling collection of leases, and plans to continue spending aggressively to go after a market that could be worth as much as $1.6 trillion. If you aren't yet a subscriber to Wall Street Insider, you can sign up here. At the center of WeWork's vision is CEO and cofounder Adam Neumann, the charismatic and controversial 40-year-old Israeli businessman who will control a majority stake of WeWork's voting power as a public company. Here are some of the WeWork stories from the Business Insider team this week: WeWork is the most valuable startup to head for the public markets since Uber earlier this year.

In the filing, WeWork lays out a path to profitability, but most of its options involve slowing its breakneck growth. WeWork CEO Adam Neumann has been criticized for perceived conflicts of interest between his investments and WeWork. Now prospective investors are getting a closer look at Neumann's web of loans, real-estate deals, and family involvement with the company. Separately, I'm excited to announce that in several weeks Business Insider will be hosting its first-ever cannabis webinar with marijuana-analytics company Headset. Earlier this year, Headset raised $12 million and signed deals with market-research firm Nielsen and the accounting firm Deloitte. You can join Headset CEO Cy Scott for a BI Prime webinar on September 5 at 2 p.m. ET as he takes readers through his pitch deck and explains how he convinced VCs, including early Juul investor Poseidon Asset Management, to buy in. Poseidon partner Emily Paxhia will also weigh in on the unique challenges of investing in cannabis — and how she picks winners in a crowded market. You can sign up here. Have a good weekend! Olivia A top Citigroup executive is departing as the bank winds down a secretive $1 billion business amid competition from private equity A little-known principal-investing team at Citigroup is being wound down, and the executive who led the group has left the firm, according to people familiar with the matter. What remains of Citi Credit Opportunities, a vestige of pre-financial-crisis banking that had $1 billion in its balance sheet to make loans to small and midsize companies, is being absorbed into the bank's broader financing operation. The boom in buy-side private-lending shops, combined with a prolonged run of low interest rates, has made this type of business more difficult and less lucrative for banks than in years past.

But companies that revolve around real estate are quickly finding ways to adapt to a digital world. Documents that used to live in a file cabinet are being digitized. Zillow, Redfin, and other "i-buyers" are closing on homes within a week of the application. Venture-capital money is flooding into "proptech" startups that marry real estate and technology.

Citi and Morgan Stanley are among a group of large global banks banding together to create a working group examining the risks they may face when using artificial intelligence, according to three sources involved in the project.
