**Trader sentiment for Kīlauea Episode 53 timing reflects the USGS Hawaiian Volcano Observatory’s tilt-based forecast window of August 8–12, with closely matched probabilities across the mid-to-late portion of that interval driven by ongoing summit inflation data.** Following the abrupt end of Episode 52 on July 29, 2026, the Uēkahuna tiltmeter recorded a switch to steady inflationary tilt totaling 10.6 microradians by early August, including 1.3 microradians gained in the most recent 24-hour period. This reinflation, paired with persistent moderate-to-strong glow from the north vent and gas-pistoning activity at the south vent system, signals accumulating magmatic pressure beneath Halemaʻumaʻu. HVO models, calibrated on historical deflation-inflation cycles during the episodic eruption that began in December 2024, currently place the next fountaining most likely between August 8 and 12, with adjustments possible if tilt trends accelerate or stall. The near-even split between August 11–12 and later dates versus earlier slots captures genuine uncertainty in the precise rate of pressure buildup. Continued positive tilt, seismic tremor patterns, and SO₂ emission trends will determine whether the episode arrives at the earlier or later end of the window; new daily updates from HVO could quickly shift market-implied odds.
