Bitcoin slips to about $81,400 as Asian chip stocks fall
CoinDesk reported that bitcoin slipped about 0.5% to around $81,400, even after U.S. spot bitcoin ETFs drew $526.6 million on the prior day, their largest daily inflow in nearly a month. The publisher tied the tone to Asian equities, where South Korea's Kospi index fell 3.73% and chipmakers SK Hynix and Samsung Electronics declined amid renewed worries over AI spending. Nasdaq 100 futures fell 0.31%, ether fell 0.9% to near $2,385, and the DeFi sector index dropped 1.2%.
Only one publisher so far. Another independent outlet or an official source would raise it.

Claims and open questions
What sources claim
- CoinDesk reported that bitcoin slipped 0.5% to around $81,400 despite U.S. spot bitcoin ETFs attracting $526.6 million the previous day, the largest daily inflow in nearly a month.
- CoinDesk reported South Korea's Kospi index fell 3.73% to its lowest close since April 7, with SK Hynix and Samsung Electronics declining on renewed AI spending worries.
- CoinDesk reported ether fell 0.9% to near $2,385 and the DeFi sector index dropped 1.2%, the weakest of the CoinDesk benchmarks.
Still unresolved
- Whether the $526.6 million ETF inflow figure reflects final settled flows or preliminary data, which an issuer or ETF data provider statement would confirm.
- Which specific AI spending developments drove the Kospi and chipmaker declines, which an exchange notice or company statement would clarify.
- Whether bitcoin's move is linked to the equity selloff in a measurable way, which would require order-flow or positioning data rather than timing alone.
