The Week
ARKK closed the week at $88.23, up 5.56%, beating the S&P 500 by about 5.64 percentage points.

Sector News
Three themes drove the ARKK-related tape this week. In crypto and blockchain, Circle launched the Arc blockchain with Wall Street partners, and after the SEC unveiled new stock tokenisation rules, tokens like UNI and HYPE jumped over 10% at one point, while Coinbase surged 11.82% on institutional buying and futures product headlines. In AI healthcare, Tempus AI posted its first profitable quarter, Twist Bioscience gained on a collaboration with Eli Lilly and Anthropic, and 10X Genomics drew attention around AI pathology. Elsewhere, SpaceX scheduled its first Starship orbital test for September 22 and Tesla expanded European Megacharger plans. Crypto and AI healthcare were the main lift for thematic ETFs this week.
The Week Ahead
The key event next week is SpaceX’s planned Starship orbital test on September 22. On the macro calendar: Richmond Fed composite index on Tuesday (Sep 22), EIA crude inventories on Wednesday, and jobless claims, current account balance and new home sales on Thursday (Sep 24). These releases will test the rate expectations triggered by this week’s Fed dot plot. Whether the crypto and tokenisation theme can extend will also depend on how the market digests the new SEC rules.
In Short
ARKK delivered a rebound well ahead of the broader market this week, led by high-beta crypto and AI healthcare names, with turnover in line with recent norms. The caveat is that gains were concentrated in a handful of theme stocks, and next week’s SpaceX test and a run of macro data will test whether the upward move can hold. With no PE or PB available for this ETF, valuation offers little anchor, and the latest session shows large and medium lots as net sellers while retail demand stays active. Whether crypto and AI healthcare flows broaden will be the next signal to watch.
