Platinum and palladium are two very similar metals — they sit right above each other on the periodic table, are found in the same mines, and are both used primarily in catalytic converters for automobiles. Up until 2016, their prices tended to rise and fall in unison.

What’s happening: Since Volkswagen’s diesel-gate, demand for platinum — used in diesel-fueled cars — has waned. Palladium, which is used for catalytic converters in gasoline-fueled cars, has benefited.

  • 'The price differential between palladium and platinum is historically unprecedented,” David Holmes, head of trading at Heraeus Precious Metals, tells Axios.

Fun fact: An ounce of palladium now costs more than an ounce of gold, for the first time since 2002.

President Trump said Judge Amy Coney Barrett's Senate confirmation to the Supreme Court and her subsequent taking of the constitutional oath Monday was a "momentous day," as she she vowed to serve "without any fear or favour."

  • But as Republicans applauded the third conservative justice in four years, many Democrats including Speaker Nancy Pelosi (Calif.) warned of consequences to the rush to replace the late Justice Ruth Bader Ginsburg ahead of the Nov. 3 election, with progressives leading calls to expand the court.

In her three decades in science, Jennifer Doudna said she has seen a gradual erosion of trust in the profession, but the recent Nobel Prize winner told "Axios on HBO" that the institution itself has been under assault from the current administration.
