The Dow Jones Industrial Average spiked nearly 500 points on Friday, erasing early morning losses after Merck announced successful results for its antiviral drug in the treatment of COVID-19, renewing optimism around the recovery from the pandemic.

Merck ended its phase three trial of molnupiravir early after it said hospitalizations and deaths were cut in half for patients that took the drug after being infected with COVID-19. The pharmaceutical company said it will file for emergency use authorization as soon as possible and plans to have 10 million available doses by the end of the year.

Merck's positive drug data helped offset the biggest jump in inflation in 30 years, with core inflation jumping 3.6% in August, and Congress struggling to raise the US debt ceiling before the US Treasury runs out of money on October 18.
