Last week's highlights on crypto ETFs

Report: Coinbase and Kraken account for 22% of AI usage in the U.S. crypto industry; IBIT dominates responses related to Bitcoin ETFs

Market analysis reports show that Coinbase and Kraken together account for 22% of all AI usage across cryptocurrency categories, with Coinbase at 13% and Kraken at 9%, leading other U.S. exchanges by more than three times.

Gemini ranks third at 5.5%, Robinhood Crypto ranks fourth at 5%, and BlackRock’s spot Bitcoin ETF, IBIT, ranks fifth at 4.5% and dominates queries related to “Bitcoin ETFs.” Analysis shows that hardware wallets are losing influence in AI responses; while Ledger and Trezor still dominate questions about “best crypto wallets,” AI is increasingly recommending regulated exchange custody solutions for questions about “best ways to store crypto assets.”

The report finds that the "self-custody narrative" that emerged after the FTX event is no longer the dominant framework cited by AI. Additionally, AI is rapidly shaping the retail crypto finance brand landscape in the U.S.: “Platforms prioritized by AI when users ask ChatGPT where to buy Bitcoin will have the opportunity to define the industry’s landscape over the next decade.”

The U.S. SEC has delayed its review of the first prediction market ETFs, which are tied to real-world events such as election outcomes and economic recessions.

According to Reuters, the U.S. Securities and Exchange Commission (SEC) has delayed its review of the first batch of prediction market ETFs, causing the launch of over 24 planned products to be postponed. Sources familiar with the matter said the SEC is requesting issuers to provide further clarification on product mechanics and disclosure details, and this delay is expected to be temporary.

Issuers such as Roundhill Investments, Bitwise Asset Management, and GraniteShares submitted applications in February this year to launch ETF products linked to real-world events such as election outcomes, economic recessions, tech layoffs, and oil prices.

Under SEC rules, ETF applications typically become effective 75 days after submission unless the regulator intervenes. Roundhill has currently set May 5 as the effective date, and Bitwise and GraniteShares products are expected to launch simultaneously. The market is closely watching whether the SEC will ultimately approve these products, which would create a new asset class of “event contracts.”

Bitwise Chief Investment Officer Matt Hougan said, "This is a rapidly maturing field, and regulation is maturing alongside it," noting that innovative products like Bitcoin ETFs also went through lengthy review processes before ultimately being launched.

President of The ETF Store: SEC Commissioner Mentions Balancing Regulation and Innovation, Predicts Market ETFs Likely to Launch

Nate Geraci, President of The ETF Store, stated on X that U.S. SEC Commissioner Hester Peirce mentioned in her speech an effort to balance regulation and innovation. Nate Geraci emphasized that this appears to refer to prediction market ETFs, which could be launched soon.

Analysis: Bitcoin rose then retraced, falling below $80,000, as ETF outflows combined with geopolitical risks weighed on market sentiment.

Bitcoin fell below the $80,000 mark for the week, as five consecutive days of net inflows into spot ETFs came to an end, and the market's rebound momentum from February lows showed signs of cooling. The U.S. April non-farm payrolls report added 115,000 jobs, exceeding the expected 62,000, while the unemployment rate held steady at 4.3%. Although the data overall was stronger than anticipated, it did not significantly alleviate market concerns about macroeconomic uncertainty; instead, it reinforced expectations that energy-driven inflation is limiting room for rate cuts.

In terms of fund flows, spot Bitcoin ETFs turned net outflows of $277 million on Thursday, ending a consecutive inflow streak totaling $1.69 billion; Ethereum ETFs also recorded net outflows of $104 million on the same day, indicating a short-term cooling in institutional risk appetite. On the geopolitical front, tensions between Iran and the U.S. have escalated again, prompting markets to reprice risks associated with the Strait of Hormuz, leading to a rebound in oil prices, which partially offset the previous support for risk assets from falling oil prices.

The derivatives market shows longer-term hawkish expectations, with interest rate futures pricing in a greater than 50% probability of rate hikes beyond 2027, suggesting that the easing cycle may be delayed until 2028. On-chain data indicates that this round of Bitcoin price appreciation has been primarily driven by institutional spot buying and short covering, while retail participation remains low; funding rates have stayed at moderate levels, reflecting weak market momentum. Analysis suggests that if retail capital does not return, BTC could still face a retest of the $75,000–$78,000 support range.

Analysis: BTC is approaching the $83,000 ETF average cost range, entering a critical validation phase for short-term price action.

Nic Puckrin, co-founder and CEO of Coin Bureau, posted on X that Bitcoin has broken above $80,000, reaching its highest level in nearly three months, and has reentered several key technical and on-chain indicator zones, including the middle of the CME gap ($79K–$84K), the bull support band, and above both the short-term holder realized price and the true market average.

Nic Puckrin analyzes that if Bitcoin’s price can stabilize within the current range, the next levels of interest include the approximately $83,000 ETF average cost range and the upper edge of the approximately $84,500 CME gap. Overall, Bitcoin’s short-term price action has entered a critical validation phase, and the market may be entering a more volatile trading window.
