Slack has confidentially filed documents to go public with the U.S. Securities and Exchange Commission, the company announced on Monday.

Why it matters: Slack has been rumored to be considering a direct listing instead of a traditional IPO. Should the workplace messaging behemoth choose that path, it will be the second tech company to do so after Spotify did so last year.

The cliffhanger could be ... Georgia

It hasn't backed a Democrat for president since 1992, but Georgia's changing demographics may prove pivotal this year — not only to Trump v. Biden, but also to whether Democrats take control of the Senate.

Why it matters: If the fate of the Senate did hinge on Georgia, it might be January before we know the outcome. Meanwhile, voters' understanding of this power in the final days of the election could juice turnout enough to impact presidential results.

Climate change goes mainstream in presidential debate

The most notable part of Thursday’s presidential debate on climate change was the fact it was included as a topic and assumed as a fact.

The big picture: This is the first time in U.S. presidential history that climate change was a featured issue at a debate. It signals how the problem has become part of the fabric of our society. More extreme weather, like the wildfires ravaging Colorado, is pushing the topic to the front-burner.

Finally, a real debate

A more disciplined President Trump held back from the rowdy interruptions at tonight's debate in Nashville, while making some assertions so outlandish that Joe Biden chuckled and even closed his eyes. A Trump campaign adviser told Axios: "He finally listened." 

The result: A real debate.
