Happy Tuesday. As someone with protein coffee in their fridge, I can't say I'm surprised that "functional beverages" are taking off.

Stock futures are positive this morning. The market is coming off a winning day.

Here are five key things investors need to know to start the trading day:

The Supreme Court had a busy morning yesterday. The nation's highest court ruled on President Donald Trump's ability to fire independent regulators and whether delayed mail-in ballots can be counted.

Here's a rundown:

As of tomorrow, Medicare will start covering obesity drugs for the first time. CNBC's Annika Kim Constantino reports that it could bring in a huge new patient population for GLP-1 producers Novo Nordisk and Eli Lilly.

Medicare Part D previously covered some GLP-1s for conditions such as diabetes or cardiovascular disease, but federal law had prevented coverage on the sole basis of obesity. With the policy change, eligible enrollees can get the drugs for a copay of $50 per month. Medicare director Chris Klomp said last week that millions of Americans are expected to gain access through the new program.

Elsewhere in pharmaceuticals, CNBC learned that Eli Lilly and Regeneron were among the first seven companies regulators selected for a pilot program to accelerate reviews of domestic manufacturing facilities. Under the initiative, regulators can start evaluating projects while they're under construction.

Comcast shares rallied yesterday after the telecom giant announced its plans to spin off NBCUniversal and Sky into a publicly traded company. Now, the question on everyone's mind is what the company plans to do next.

As CNBC's Lillian Rizzo and Alex Sherman write, analysts believe Comcast is getting ready to make deals. But Comcast co-CEO Brian Roberts dismissed that expectation on a call yesterday, telling investors that the announcement was "absolutely not" a precursor to any mergers and acquisitions.

Still, some on Wall Street are wondering if Comcast could look to merge with cable company Charter Communications. In this situation, the media business would look more like Disney.

Uber users can no longer hail Waymo robotaxis in Phoenix. As CNBC's Lora Kolodny reports, the program's end raises concerns about the rideshare platform's dominance in the space.

Waymo vehicles in Phoenix will now be used for autonomous deliveries with DoorDash. Uber said it would partner with another autonomous vehicle company in the Phoenix market, but did not say which one. For its part, Waymo is still operating rideshare services in other cities, with plans to add Nashville later this year via Lyft.

While experts don't see online Trump Accounts as solving the retirement savings gap between genders, they believe it could help. Here's how much each gender had saved in their retirement accounts at the end of 2025, according to a new Vanguard report:
