Millions of stock and options traders were effectively shut out of the market for all of Monday as well as two hours of early trade on Tuesday.

Driving the news: The culprit was Robinhood, a fast-growing stock-trading platform that inexplicably face-planted on a day when trading volume surged and the stock market rose by 4%.

Why it matters: Robinhood was valued during its last fundraising round in July at $7.6 billion, based on the thesis that bringing Silicon Valley's disruptive norms to Wall Street would help the company capture an audience of fast-twitch millennials. This week's news is a reminder of why old-fashioned trustworthiness has its merits.

The big picture: Robinhood's unbeatable price of $0 for stock trades ultimately prompted all its major competitors to follow suit. That, in turn, begat mega-mergers: Morgan Stanley is buying E-Trade, while Charles Schwab is buying TD Ameritrade.

Be smart: Now that giants like Fidelity and Vanguard Group have massive scale and $0 trades, it's hard to see where Robinhood's comparative advantage lies. The 7-year-old startup risks finding itself racing to the bottom, signing up mainly options traders who don't qualify for margin accounts anywhere else.

Flashback: Robinhood is known for overreaching. At the end of 2018, it announced a checking account and was then forced to ignominiously unannounce it. In 2019, users found a glitch that gave them "infinite leverage," and Robinhood was also fined $1.25 million for not giving its users the best prices on stocks.

  • The outage this week is Robinhood's worst blunder yet, and only serves to reinforce the impression that the brokerage is not robust enough to stand up to the giants in the space.

What they're saying: Robinhood is blaming "instability in a part of our infrastructure that allows our systems to communicate with each other" for the outages on both Monday and Tuesday. The company is saying that service is now "fully restored."

The bottom line: Wall Street is built on trust. It's hard to see why any of Robinhood's customers should trust it at this point.

NYT: White House drug price negotiations broke down over $100 "Trump Cards"

Negotiations on a deal between the White House and pharmaceutical industry to lower drug prices broke down last month after Mark Meadows, the president's chief of staff, insisted that drugmakers pay for $100 cash cards to be mailed to seniors before the election, according to the New York Times.

Why it matters: Some of the drug companies feared that in agreeing to the prescription cards — reportedly dubbed "Trump Cards" by some in the pharmaceutical industry — they would boost Trump's political standing weeks ahead of Election Day with voters over 65, a group that is crucial to the president's reelection bid, per the Times.

In some parts of Virginia, people waited in line up to four hours to cast their ballots on the first day of early voting, according to the Washington Post.

The big picture: The COVID-19 pandemic seems to already have an impact on how people cast their votes this election season. As many as 80 million Americans are expected to vote early, by mail or in person, Tom Bonier, CEO of TargetSmart, a Democratic political data firm, told Axios in August.
