24h volume of $46K equals 33% of all-time handle, a sharp single-day concentration with two weeks left.
Fresh activity likely tracks a recent benchmark release or lab announcement putting the threshold within reach.
Resolves Sept 30, 2026, the tight window compresses risk and draws attention as the deadline nears.
