The last major with a clearly reported live crowd was the CS:GO Paris Major , which drew 50,000 fans in total across the event, with the arena sold out at 20,300 capacity for the final stage at Accor Arena.

What that means

  • Total event attendance: 50,000 fans.
  • Arena capacity for the final venue: 20,300 people.
  • Context: That Paris event was the last CS:GO Major before the switch to CS2.

If you meant CS2 specifically

The latest CS2 Major coverage in the available results focuses on viewership records and not a clearly stated in-arena crowd figure, so the safest verified answer is the Paris Major attendance numbers above.
