Spot BTC ETFs just booked their best week of 2026: $2.39B in net inflows through September 25, seven straight trading days of buying, with price holding above $84K.

Here's the part that matters more than the headline number: BTC dominance is sitting at 58.5% right now. That means this institutional demand isn't rotating out into alts once it lands — it's concentrating in BTC and effectively starving altcoin beta of the flow it usually gets during risk-on stretches. IBIT and FBTC have been the two biggest single-day absorbers of that flow this week.

If you're running systematic books, that's a real signal: correlation to BTC-only flow is higher right now than correlation to broad "risk-on" sentiment. Alt longs that worked on the last leg up may not work the same way this time.

Are you fading alt beta here, or riding the BTC-only flow until dominance breaks?
