The tokenized stock pricing problem has a shape, and it is a calendar. NYSE and Nasdaq trade about 32.5 hours per week out of 168, so any venue offering around-the-clock onchain trading spends most of each week without a live reference price for the asset it is selling. The SEC's new exemption permits qualifying tokenized stocks to trade through permissioned automated market makers, but it does not change the hours of the market underneath. Marcin Kaźmierczak, co-founder and chief operating officer of oracle provider RedStone, argues that gap matters more than liquidity fragmentation or arbitrage, because the mechanism that normally keeps token prices honest quietly goes home for the weekend.
Why tokenized stock pricing breaks after hours
"An AMM only prices off its own pool, arbitrage keeps that honest but only while the reference market is open, and NYSE/Nasdaq trade about 32.5 hours a week out of 168," Kaźmierczak said. During regular US trading hours, market makers can compare the onchain token with the underlying share and trade away any difference. Overnight or on weekends, the stock's deepest venue is not publishing an executable price, so the AMM reacts only to orders inside its own pool. Large trades can move the quoted price even when investors cannot buy or sell the underlying share to complete the other side of an arbitrage. The failure mode is not dramatic, it is quiet: a price that looks live but is really just the last few traders in a small room.
The problem compounds rather than fades with growth. "It gets harder, not easier. Price impact per AMM trade grows with size, and the hours without a live reference price don't shrink just because volume goes up," he said. More volume means bigger orders, and bigger orders move pool-priced markets more per trade. The 24/7 tokenized markets conversation usually centers on settlement, as in the weekend dollar funding gap analysis, but Kaźmierczak's point is upstream of settlement: before you can settle a trade, you need a price that means something.
Two classes of tokenized product, one underlying stock
The exemption also splits the market in a way the rulebook has not caught up with. Qualifying ownership tokens must carry the same rights as the conventional share, while synthetic products already available through offshore services track price without conveying ownership. "So you don't just get tokenized versus traditional, you get two classes of tokenized product for the same underlying stock, priced differently, under different rules," Kaźmierczak said. An investor can hold a conventional US share, a fully backed ownership token under the SEC framework, and a synthetic or wrapped product tied to the same company, each with different rights, different halts and different risk. The structures vary even among share-backed tokens: Coinbase's tokens represent beneficial interests held through an offshore special-purpose company and a regulated broker, with redemption gated behind identity and compliance checks, as its real-securities model documents, while Robinhood's synthetic tokens drew a public objection from AMC over exactly this distinction, a fight Bitnxt covered when the company questioned the 1:1 backing claims.
Kaźmierczak noted the irony that the products causing the governance fights are synthetic and therefore outside the new framework entirely. The SEC included issuer notice and objection rights for ownership tokens, but the synthetic sector that angered AMC's CEO does not have to follow them. Regulation is drawing a precise border around the part of the market that was behaving, while the part that wasn't keeps operating under whatever rules its offshore issuers choose.
What the infrastructure needs next
The fix list follows from the diagnosis. Around-the-clock markets need reliable price information when the underlying market is open, and explicit rules for when it is not, including how venues flag stale references, cap price discovery to pool depth, or bridge weekend gaps with oracle aggregations of correlated instruments. Kraken's new xStocks vaults, which accept SPYx, QQQx and NVDAx as collateral for stablecoin loans routed through cross-chain strategies, add another layer: collateralized products priced on tokens that are themselves priced on thin pools. "Price risk scales with data infrastructure. Consent risk scales with governance," Kaźmierczak said. "Neither is solved by this exemption alone, and both compound as volume grows."
For traders, the practical guidance is simple. A weekend price on a tokenized stock AMM is an estimate produced by the venue's own liquidity, not a market price, and treating it as one is how the weekend premium becomes Monday's loss. For builders, the opportunity is equally plain: whoever solves after-hours reference pricing, through oracle composites, broker-quoted indications or exchange-licensed data feeds, removes the largest structural complaint about the SEC's new framework. The exemption opened the door. The data layer decides whether anyone walks through it at 3 a.m. on a Sunday.
