How full will Vegas be during Black Hat USA 2027?

Busy: expect firmer rates near the venue; book private dining and group blocks early.

Black Hat USA 2027 falls mostly in the week of Aug 2, 2027, which we rate Busy on trade-show attendance: about 57,333 trade-show attendees in town (pro-rated), counting Black Hat USA 2027 and 3 other tracked shows that overlap its dates.

1 show(s) in this window have no published attendance, so the real number is higher.

Overlapping shows

Each Monday-Sunday week gets one score: the pro-rated attendance of every tracked trade show in town that week. The score sets the week’s trade label. A trade show carries the trade label of the week that holds most of its days (ties go to the busier week), on every tile and page. A week’s headline label can be lifted by the leisure floor (“Busy (leisure)” or “Peak (leisure)”); trade-show tiles never inherit it. Method.

When to book entertainment for Black Hat USA 2027

Book entertainment: Plenty of time

Based on typical lead times for headline and booth entertainment (status as of Oct 18). In Packed or Sold-out weeks, book at the early end; private rooms and hotel blocks go fast too.

What is Black Hat USA?

Black Hat USA is the flagship of Black Hat, a cybersecurity event series founded in 1997 and run by Informa. It mixes technical Trainings, Briefings on new research, specialized Summits and a Business Hall of security vendors at the Mandalay Bay Convention Center.

Who attends: Security practitioners, researchers, CISOs and other security leaders, government officials and cybersecurity vendors. In 2025 the Business Hall had more than 425 solution providers.

Attendance trend: Up from 20,000 verified attendees in 2025 to more than 23,000 in 2026, per Black Hat. Attendance history.

When it usually happens

Early August at Mandalay Bay, running about six days with Trainings first and Briefings at the end. Black Hat USA 2027 runs Saturday, July 31 to Thursday, August 5, and DEF CON 35 starts the same Thursday (Aug 5-8) at the LVCC, so the two form back-to-back security weeks.

Where to stay: nearby hotel clusters

Mandalay Bay Convention Center: Mandalay Bay, Delano and Four Seasons share the complex. A free tram runs to Luxor and Excalibur, and MGM Grand, New York-New York and Park MGM are a short ride north on the south Strip.
