$ARM 24 hours, up 15.48% to $328.47, and the funding rate is positive at 0.00007150. There’s no new catalyst on the global news front—this rally is driven entirely by long contract sentiment. A positive funding rate means longs are paying shorts, with longs’ carrying costs increasing every day; this structure can’t hold for long.

Even as the price rises, positive funding is a classic signal of crowded longs. The last time I saw a similar setup was in other tech stock contracts: after longs chased higher for three days, the funding rate spiked, and then a sharp pullback followed. Now the OI of $ARM is 26,364 lots, with trading volume close to $50 million; liquidity is concentrated around the current price. Once profit-taking sells come in, the drop should be very smooth.

The strongest counterargument is that if the world suddenly breaks major positive news about AI chips, $ARM could get blown up by sentiment directly. But the probability isn’t high—right now it’s more of a zero-sum battle among existing capital. The second-order effect is that if price turns around, forced liquidations from longs would intensify the selloff; even though shorts are paying funding right now, they’re waiting for exactly this moment.

My invalidation conditions are: the funding rate turns negative and the price moves above $335. I’ve already cut my long position by half and kept the other half to observe.
