Ark Invest expanded its positions in Coinbase, Circle, Bullish, and Robinhood on Thursday after each stock closed lower. The investment firm spread the purchases across three exchange-traded funds while Coinbase-backed Base restored block production after a nearly two-hour network interruption. The buying activity came as Ark CEO Cathie Wood also shared her latest view that inflation continues to slow as productivity keeps improving.
Ark Invest's latest trading disclosure showed purchases across several crypto-related companies. The firm acquired 9,014 Coinbase shares through the ARKK, ARKW, and ARKF exchange-traded funds. Based on Thursday's closing price, the purchase carried an estimated value of about $1.28 million.
The firm also purchased 9,264 Circle shares valued at roughly $637,455. In addition, Ark bought 9,136 Bullish shares worth about $199,895. Through the ARKK fund, Ark also acquired 35,023 Robinhood shares valued at approximately $3.27 million.
Meanwhile, all four stocks finished the session lower. Coinbase declined 5% to $142.52. Circle lost 3% to close at $68.81. Robinhood dropped 3.85% to $93.47, while Bullish fell 6.77% to $21.88.
Ark actively manages the weightings inside its exchange-traded funds. The firm aims to keep no individual holding above 10% of a portfolio. As a result, it adjusts positions whenever large price movements change portfolio allocations.
During a roadshow across Asia and Europe, Cathie Wood said many investors continue to worry about inflation. She stated that inflation could decline further and said lower oil prices were not the only reason.
Wood pointed to unit labor costs, saying inflation measured by that indicator had already slowed to 0.5% year over year. She linked that trend to stronger productivity.
She also commented on Kevin Warsh in a thread on X. Wood said she believes Warsh understands both the role in lowering inflation and weaknesses in government inflation measurements. She added that financial markets could receive what she described as a master class in monetary policy if Warsh takes that approach.
Elsewhere, Coinbase-backed Base resumed normal operations after a consensus issue stopped block production for almost two hours on Thursday. The Ethereum layer-2 network confirmed that engineers resolved the problem and blocks returned to normal production.
Base first reported unhealthy block production at 4:03 p.m. UTC through its official status page. The team later identified a consensus issue involving an invalid block that entered sequencing. The incident stopped new blocks after block 47,806,542.
Later, Base announced through X that block production had fully resumed across the network. The team said it would continue investigating the incident before releasing a complete post-mortem explaining the root cause and future safeguards.
Base creator Jesse Pollak said user funds remained safe throughout the interruption. He also acknowledged that a network halt was unacceptable for a platform designed to support global financial activity.
The outage temporarily paused new on-chain transactions across the network. Base also instructed ecosystem node operators to restart their nodes so syncing could return to normal. The team confirmed that internal nodes resumed syncing correctly while engineers continued their investigation.
Ark Invest increased its holdings in Coinbase, Circle, Bullish, and Robinhood as their share prices declined. Meanwhile, Base restored normal operations after a brief network halt, while Cathie Wood maintained that improving productivity could continue to ease inflation. Investors will likely watch both market activity and network developments closely.
