KULR Technology Group moved 300 bitcoin into Coinbase Prime on Wednesday, on-chain data shows. Analysts following corporate treasury movements say the deposit looks like a sell, not a routine custody shuffle. The thermal management and energy storage company launched a bitcoin treasury earlier this year, but that bet has soured fast — KULR now sits on unrealized losses of roughly $18 million.
What the on-chain data shows
The transaction was published to the blockchain Wednesday. Coinbase Prime is a platform companies often use for trading, not just storage. That has analysts reading the deposit as a signal KULR may be looking to exit part of its position. The company itself hasn't commented on the move.
The size of the paper loss
KULR's bitcoin holdings are deep in the red. With the price of bitcoin under pressure this spring, the company's unrealized losses have swelled to nearly $18 million. That's a meaningful hit for a firm whose core business is thermal management hardware for batteries and electronics — not crypto speculation.
A quiet Friday ahead
KULR hasn't filed any disclosure about the deposit as of Wednesday evening. If the company does sell, it would lock in those losses and mark a sharp reversal from the treasury strategy it announced in early 2026. The next quarterly filing will show whether the bitcoin is still on the books — or gone.
