Investors: Return backers include Sequoia Capital, General Catalyst and Andreessen Horowitz.

• This round is not yet closed, as the company remains in discussions with new investors. Stripe co-founder and president John Collison declined to say if the entire $250 million is spoken for by insiders, who then would cut back their allocations for newbies, or if some of it still needs to be filled.

The bottom line: "Investors view payments companies like Stripe as a way to get exposure to a basket of fast-growing public and private tech companies, since Stripe’s revenues are tied to its customers’ growth. The market for payments services is also expanding as more commerce moves away from physical stores and toward digital storefronts," writes the Wall Street Journal's Peter Rudegeair.

• Sources I spoke with are split on the depth of Warren's actual knowledge of financial markets. Some say she knows more than almost anyone else in D.C., while others say she knows just enough to be dangerous.

What they're saying: Warren worries were a persistent theme on the sidelines of a CNBC conference yesterday.

• CNBC's Jim Cramer said earlier that the message he hears from Wall Street about Warren is that "she's got to be stopped."
• Steve Rattner, the onetime private equity exec and Obama car czar, recently told MSNBC that his fellow Democratic donors have "enormous nervousness" about Warren.
• Fox Business Network's Stuart Varney last week said: "Warren would force all big companies to take a lot of their profit away from shareholders. And it would be given to the workforce, the community, customers, the local and global environment, and community and societal factors (whatever that is)."

Worth noting:Assume Varney is also aghast at the 181 big company and Wall Street CEOs who signed onto the Business Roundtable's new mission statement.

The bottom line: This hand-wringing will intensify if Warren's polling momentum persists, but Wall Street ultimately will try figuring out how to best work with a possible Warren White House, rather than against it. After all, that's what it's largely done with Trump.

The latest: Juul keeps getting hit left and right these past few weeks — particularly after the recent spate of vaping-related lung diseases. Juul is also facing a possible Congressional subpoena after failing to provide documents in July.

• Last week, President Trump proposed banning all flavored vaping pods from the U.S. market, including mint and menthol.
• Earlier this week, Juul products disappeared from Chinese e-commerce sites JD.com and Alibaba's Tmall, without explanation.
• Yesterday, India banned e-cigarettes entirely.
