SEC Custody Rules, Kalshi Scrutiny and Tether in Iran | Ahead of the Curve

Welcome back to Ahead of the Curve from K33 Research. It is Monday, October 5th, 2026. Today's episode is based on our This Week in Crypto report from Friday, October 2nd, with the time-sensitive parts checked again this morning. The main theme is regulation moving forward even after Congress failed to settle the broader crypto framework. The SEC is proposing a new custody regime, the CFTC is trying to define the boundary around prediction markets, and Kalshi is under scrutiny over unusual trading volumes. Separately, a Senate minority investigation has put Tether's role in Iran's shadow financial system back under the spotlight.
Start with custody. On October 1st, the SEC proposed a new framework for registered investment advisers and regulated funds holding crypto. The important word is proposed. Nothing here is in force yet. If adopted, state-chartered trust companies could serve as custodians under specified conditions. Advisers could also hold client crypto directly in limited cases, but only after determining that no permitted custodian is available, and that conclusion would have to be revisited every quarter. Hester Peirce made an important distinction in her statement: this is not self-custody by the investor. It is the adviser itself acting as custodian. For asset managers that want direct crypto exposure rather than only using an ETF, that could open a clearer compliance path, but the guardrails matter.
This also continues a shift we covered after the Clarity Act failed in September. Congress did not deliver a comprehensive market structure law, but the agencies did not stop. The SEC has moved ahead with the custody proposal and other crypto initiatives, while Chair Paul Atkins says more proposals are coming. As of Monday, the custody rule is still at the proposal stage, and the SEC still describes the comment period as 60 days from publication in the Federal Register rather than giving a fixed closing date. So the direction is clear, but the final rule is not.
Next, Kalshi. The platform plans to end its Volume Incentive Program no earlier than October 13th. The program pays traders based on their share of eligible volume and was designed to support liquidity. The timing has attracted attention because Kalshi's crypto perpetuals have faced wash-trading allegations. One researcher pointed to roughly $539 million of Ether perpetual volume in a day against only about $3.1 million of open interest, along with repeated trades around $5,500. The Wall Street Journal later reported that trades of roughly that size generated more than $5 billion of volume over a month. Those numbers are unusual, but they are not, by themselves, proof of wash trading. Kalshi denies that wash trading occurs on the platform and has said the patterns reflect liquidity incentives and market makers repeatedly posting quotes. Public reporting says the CFTC has been examining the activity, while Kalshi says it has not been contacted and does not believe it is under formal investigation.
That sits inside a bigger fight over what prediction markets actually are. The CFTC has sent two rulemaking packages to White House review. One would broaden the definition of a swap to include event contracts. The other would carve out casino-style gambling products. As of the latest public review record, both are still pending. States continue to argue that sports and other event contracts can fall under state gambling laws, while the CFTC has been pushing for federal derivatives oversight. The practical issue is not just whether prediction markets survive. It is where the line is drawn between a regulated financial contract and gambling, and who gets to draw that line.
Then there is Tether and Iran. A Democratic staff investigation from the Senate Permanent Subcommittee on Investigations analyzed hundreds of wallets linked to Iran and its regional proxies. Among 757 wallets implicated in terrorism financing, the report says 87% had predominantly transacted in USDT. The allegation is not that Tether lacks the ability to freeze funds. It is that the company did not always act quickly or consistently enough when wallets were linked to sanctioned actors. Tether has responded by emphasizing its cooperation with law enforcement and says actions involving USDT have frozen roughly $550 million across Iran-linked wallets in 2026. That disagreement is important because it goes directly to the difference between a stablecoin like USDT and Bitcoin.
USDT gives users dollar exposure without requiring a dollar bank account. That makes it useful for ordinary households dealing with inflation, but also for institutions and networks cut off from the banking system. Its weakness, from the user's perspective, is also its strength from an enforcement perspective: Tether can blacklist addresses and freeze tokens. Bitcoin has no issuer with that kind of switch. Enforcement therefore moves toward identifying actors, controlling exchanges and other intermediaries, and making it harder to convert between crypto and the traditional financial system. The report shows how those routes are becoming more complex. The average number of transfers between Iran's largest exchange and compliant global exchanges rose from 1.6 in 2021 to 4.1 in 2025. More hops do not make transactions invisible, but they do make enforcement harder.
That is the main takeaway from the Friday report as we record on Monday. The SEC custody framework is moving, but it is still a proposal. The CFTC's prediction-market rules are still under review. The Kalshi allegations remain contested. And the Tether story is now moving from blockchain analysis and political scrutiny toward the question of whether Treasury or the Justice Department takes further action. The next phase is less about headlines and more about what actually becomes a rule, an enforcement action, or a workable market standard.
