Sui hits 1,539 TPS on May 30, 2026 as outages weigh on SUI’s weekly drop

Sui posted a new yearly throughput high of 1,539 transactions per second at 02:00 UTC on May 30, 2026, while traders digested a separate stretch of network slowdowns. SUI slid 14.7% over the week to $0.9017 after failing to hold $1.00, with the selloff accelerating around May 28 as congestion signs appeared. Market attention is now split between the scalability milestone and whether reliability stabilizes.
