Google's Home device. (Walmart)

Walmart and Google are escalating a fierce battle to own virtual assistant shopping, jointly challenging Amazon's towering dominance over the already-lucrative new space in retail, per the WSJ's Jack Nicas and Laura Stevens.

Google is offering up its Home virtual assistant (photo above) and Walmart its vast inventory. As of next month, they will team up on Google Express, the internet giant's e-commerce marketplace. In doing so, they are going against Amazon's Echo.

  • The mountain is steep: As of July, Amazon raked up 45 cents of every dollar spent on-line, up from 43 at the start of the year. Walmart earns just 2 cents. Google's House personal assistant is 26% of the market; Echo is the rest.
  • But the prize is too large to ignore: Amazon has already decimated whole swaths of brick-and-mortar retail, and now has an early grip on the new voice-activated virtual assistant market. Walmart does not want to end up like Macy's and Barnes & Noble, and Google is not satisfied to be an also-ran in e-commerce.
  • So big players are aligning: Walmart is also doing test runs using Uber and Lyft in an attempt to speed the delivery of fresh produce bought through Google Home.

How it works: Pioneered in China, sophisticated voice-activated devices are one of the next waves of technology. Before you know it, you will use virtual assistants for much of your shopping, household chores and office work.

  • It's easier after you get started: Once you've bought a certain brand of toothpaste or toilet paper, you can simply tell your assistant, "toothpaste," and it will have the same brand shipped to you.
  • Free shipping: Amazon has chalked up much of its gains through its $99-a-year Prime program, which offers free shipping. Against that, Google and Walmart are dropping their annual fee entirely if your order hits a minimum, like $25 or $35. The jury is out whether that will prove more effective than Amazon Prime.

The Centers for Disease Control and Prevention said in updated guidelines Tuesday that some immunocompromised people who have received either Pfizer or Moderna's COVID-19 vaccines will be able to get a fourth shot.

Details: People over 18 who are "moderately to severely immunocompromised" and have received three doses of an mRNA vaccine may get a fourth shot (of either the Pfizer, Moderna, or Johnson & Johnson vaccines) at least six months after getting their third Pfizer or Moderna dose, per the CDC.

Scoop: Biden plan expected to include at least $500B for climate

Photo: Stephanie Keith/Bloomberg via Getty Images

The White House is privately telling lawmakers the climate portion of President Biden's roughly $2 trillion social spending plan is "mostly settled" and will likely cost more than $500 billion, two sources familiar with the talks tell Axios.

Why it matters: A pricetag of $500-$555 billion is a huge number and, if it holds, would likely be the single biggest component of the sweeping package. It also isn't far off from the roughly $600 billion proposed when the bill was expected to cost $3.5 trillion.

The Biden administration has asked its partners in the Gulf and elsewhere to press the Sudanese generals who carried out a coup on Monday to release captives including Prime Minister Abdallah Hamdok and to reinstate the civilian government, White House National Security Adviser Jake Sullivan said in a press briefing on Tuesday.

Why it matters: The U.S. has limited influence over coup leader Gen. Abdul Fattah al-Burhan and other military leaders, many of whom have close ties to Saudi Arabia and the United Arab Emirates.
