Global IPO Pipeline Hits Inflection as SEC Moves to Rewrite Equity Trading Rules

The week of July 28, 2026 will be remembered as one of those stretches where the IPO calendar and the regulatory calendar collide — and both point the same direction. Issuance is surging globally, led by Asia. The SEC is moving to dismantle the core plumbing rule that has governed U.S. equity trading for two decades. And tokenized securities are quietly going live on the New York Stock Exchange. Each of these stories is significant on its own. Together, they describe an inflection point in how capital is raised and how it trades.

The IPO Pipeline Opens Wide

CXMT: The Largest Semiconductor Listing on Record

ChangXin Memory Technologies (CXMT), China’s largest DRAM manufacturer, closed its first day of trading on the Shanghai STAR Market on Monday, July 27, at 49 yuan per share — a 465.82% surge from its IPO price of 8.66 yuan.^[1] The Hefei-based company raised 57.92 billion yuan (approximately $8.6 billion) in the offering, making it the largest mainland semiconductor listing on record and vaulting CXMT to the position of China’s most valuable A-share company, with a market capitalization exceeding 3.2 trillion yuan (roughly $484 billion).^[1][2]

The context matters. CXMT held a 7.67% share of the global DRAM market in 2025, according to its prospectus,^[1] and the debut arrives amid a global memory shortage that has been pushing DRAM prices higher. The company plans to use proceeds primarily for mass-producing memory wafers.^[1] A 466% first-day pop is the kind of move that raises questions about pricing discipline, but it also signals something structural: Chinese capital markets are channeling enormous domestic liquidity toward strategic semiconductor self-sufficiency, and investors are rewarding that trajectory aggressively.

Zhongji Innolight: Hong Kong’s Biggest IPO Since 2019

On the same day CXMT was rocketing in Shanghai, Zhongji Innolight — a Chinese optical transceiver maker and AI infrastructure supplier — raised HK$53.4 billion (approximately $6.8 billion) after pricing its Hong Kong listing below the maximum offered.^[3] The offering is poised to become Hong Kong’s biggest share sale in nearly seven years, since Alibaba’s $12.9 billion secondary listing in 2019.^[3]

Innolight is a key supplier in the AI data-center supply chain, and its listing underscores how Hong Kong is reasserting itself as the venue of choice for Chinese tech companies seeking international capital. Bloomberg reported the deal priced below the top of the range,^[3] which is worth noting — it suggests underwriters were careful not to overreach even in a receptive market. The Reuters description of the offering as “Asia’s second-largest listing of 2026”^[3] places it behind only CXMT itself.

Jersey Mike’s: A $1 Billion Consumer IPO on NYSE

Back in the U.S., Blackstone-backed Jersey Mike’s Subs (proposed ticker: JMKE) launched its roadshow on July 20, marketing approximately 43.5 million shares at $21 to $25 each.^[4] At the midpoint, the deal would raise roughly $1 billion, with about 68% of the shares sold by existing stockholders — meaning this is partly a liquidity event for insiders, not purely fresh capital.^[4] The implied market capitalization ranges from $6.7 billion to $7.8 billion.^[4] Pricing is expected July 30 with trading on the NYSE.^[5]

The sandwich chain’s debut is a signal that the U.S. IPO window has widened beyond AI and semiconductor names. Consumer-facing companies with proven unit economics are testing the waters, and a $1 billion raise for a franchised restaurant chain tells us underwriters see genuine appetite for non-tech new issuance.

Ionic Digital: A Direct Listing for AI Infrastructure

Ionic Digital (IOND) began trading on Nasdaq on July 28 via a direct listing — not a traditional IPO — with a reference price of $53.^[6] The company, which originated from Celsius bitcoin mining assets and has pivoted toward AI and high-performance computing infrastructure, opened at $50 and surged more than 25% to nearly $63, giving it an implied valuation of roughly $2.75 billion.^[6]

A direct listing is structurally different from an IPO: no new shares are issued, no underwriters set the price, and the market discovers the clearing level. That Ionic chose this route — and that the stock traded above its reference price — tells us the format is working for companies that want public-market access without dilution. The 10.8 million shares registered^[5] create a float that market makers can work with, and the first-day premium suggests genuine buy-side interest rather than a manufactured pop.

The Week’s IPO Calendar at a Glance

The SEC Proposes Rescinding Reg NMS Rule 611

While new listings dominated headlines, the most consequential market-structure development of the quarter may be the SEC’s June 11 proposal to rescind Rule 611 (the trade-through rule) and Rule 610(e) (the prohibition on locked and crossed quotations) of Regulation NMS.^[7][8]

What Rule 611 Does — and Why It Matters

Rule 611, adopted in 2005, requires trading centers — exchanges, ATSs, OTC market makers, and broker-dealers that internalize order flow — to establish and enforce policies designed to prevent executions at prices worse than protected quotations displayed at other venues.^[8] In plain terms: if one exchange is showing a bid of $5.00 and another is showing an offer of $5.01, a broker generally cannot execute a buy order at $5.02 without first trying to access the better-priced quote.

The SEC’s proposal would eliminate this requirement entirely. Trading centers would no longer need to route to better-priced venues before executing internally. Exchanges would be permitted to display quotes that lock or cross each other — currently prohibited under Rule 610(e).^[8]

The SEC’s Rationale

The Commission offers three principal arguments:

1. Market forces should shape structure. The SEC believes removing Rule 611 will “empower market participants to compete on merit and innovation — whether through service, price, technology, costs, or a combination thereof.”^[8]
2. Rule 611 has had adverse consequences. The proposal identifies exchange proliferation, liquidity fragmentation, complex order types, and harm to institutional investors as unintended effects.^[8]
3. The rule is no longer necessary. Today’s markets are highly automated and interconnected, and routing technology is widely available.^[8]

Who Wins, Who Waits

The proposal cuts unevenly across market participants. Large wholesalers and broker-dealers that internalize order flow gain the most — they would no longer be required to route to better-priced external quotes before executing internally.^[8] Smaller exchanges that currently benefit from trade-through protections could face reduced order flow.^[8]

For institutional investors, the calculus is mixed. The rescission could provide greater flexibility to access liquidity, reduce information leakage, and minimize the costs of sourcing across multiple venues.^[8] For retail investors, who generally place greater value on obtaining executions at the best displayed prices, the removal of trade-through protections is more likely to be felt negatively — at least until best-execution frameworks adapt.^[8]

The comment period remains open for 60 days following Federal Register publication, and the SEC has requested feedback on whether best-execution requirements should be updated, whether access-fee caps should be revised, and how any transition should be implemented.^[8] Significant revisions before a final rule are likely. I’d put the probability of Rule 611 being rescinded in something close to its proposed form at roughly 60/40 — the direction of travel is clear, but the comment process could substantially reshape the implementation.

NYSE Tokenization: Quietly Live

In April 2026, the SEC approved SR-NYSE-2026-17, a rule change allowing the New York Stock Exchange to list and trade tokenized versions of Russell 1000 stocks, major ETFs, and Treasury products.^[9] By late May, the rule had moved into operative status across the NYSE and its sister venues (NYSE American and NYSE National, which filed parallel rule changes in May).^[9]

The mechanics: the Depository Trust Company (DTC) is operating a pilot program under a December 2025 SEC staff no-action letter that allows securities to be represented in tokenized form on a distributed ledger while remaining subject to existing exchange rules.^[9] The tokenized securities trade under the same Rule 7.39E framework as traditional securities, meaning they participate in the same price-discovery and best-execution infrastructure — for now.

What makes this relevant to the Reg NMS debate is a point the Skadden analysis flagged: the rescission of Rule 611 “may reduce certain market structure challenges associated with applying trade-through requirements in emerging trading environments that are not interconnected in the same manner as traditional equities markets.”^[8] In other words, the SEC may be clearing away a rule that would be difficult to enforce across tokenized venues precisely because those venues are not yet interconnected the way traditional exchanges are. That is a trajectory worth watching: if tokenized securities proliferate and Rule 611 disappears, the competitive landscape between traditional and on-chain trading venues could shift faster than most market participants currently expect.

What to Watch Next

• Jersey Mike’s pricing (July 30): The final price range and first-day performance will be a clean read on whether the U.S. consumer-IPO window is genuinely open or merely cracked. If the deal prices at the high end and trades up, expect more consumer-facing filings in August.

• Reg NMS comment letters (due approximately August 17): Watch for submissions from Citadel Securities, Virtu, NYSE, Nasdaq, and the Investors’ Exchange (IEX). The tone and specifics of these letters will signal whether the industry is coalescing around the proposal or fragmenting. Any letter that proposes a compromise — say, rescinding 610(e) while retaining a modified 611 — would be a leading indicator of where the final rule lands.

• DTC tokenization pilot metrics: The SEC’s no-action letter expires, and the pilot’s first real usage data will reveal whether institutional participants are actually settling tokenized positions or whether the framework remains theoretical. Low early adoption would not be surprising; near-zero adoption would be a tell that the plumbing isn’t ready.

• Hong Kong listing pipeline: With Innolight’s $6.8 billion deal, Hong Kong’s 2026 listing proceeds could surpass the nearly $37 billion raised in 2025.^[3] Watch for follow-on filings from other Chinese AI supply-chain companies — if they come, it confirms a structural shift, not a one-off.

• Scribe Therapeutics (SCTX): The clinical-stage biotech closed its IPO on July 27 with full exercise of the underwriters’ overallotment option.^[2] Biotech IPO closings with greenshoe exercises are a gauge of specialist-demand depth — a category that has been muted for two years.

The convergence is what matters. Record Asian IPOs, a U.S. listing window broadening beyond tech, the SEC proposing to rewrite the rules that govern how every equity trade is routed, and tokenized securities going live on the world’s most iconic exchange — these are not isolated events. They are the visible parts of a deeper reshaping of where capital is raised, how it is priced, and what “best execution” will mean in a market where the venues themselves are multiplying and the rules connecting them are being rewritten. The comment period on Reg NMS will tell us how fast this moves. The IPO calendar will tell us how hungry the buy side is. Both are worth watching closely over the next six weeks.
