Those warnings come ahead of Anthropic's expected Nov. 18 US-time pricing and Nov. 19 Nasdaq debut. Bloomberg News reported on Nov. 11, citing people familiar with the matter, that orders already exceeded the available shares multiple times.
The venues' terms make clear that money can become unavailable while an allocation is determined, and receiving tokens can mean paying above the offering price without acquiring direct shareholder rights.
SpaceX showed how an IPO subscription can fail
In a June 12 notice, Bybit said xStocks could not deliver the underlying SpaceX assets, leaving the exchange with no allocation.
Bybit promised automatic refunds of all subscribed funds in the original subscription asset. Eligible participants were also promised a reward calculated at a 10% annualized rate for a fixed four-day period.
Anthropic's Nov. 10 preliminary prospectus offers 825 million Class A shares at an estimated $70 to $78 each. About 801.4 million are company shares and 23.6 million are being sold by existing holders, whose sale proceeds do not go to Anthropic.
Bloomberg News reported that the public offering could total up to $64 billion. A separate $26 billion Class N private placement would bring the combined amount to as much as $90 billion.
Terms differ on cost
The published charges apply only to the amount allocated:
Kraken reserves money when a user submits interest and charges it only if an allocation is received, and reserved funds remain unavailable until allocation or release. Its cancellation right ends at a communicated cutoff, after which the submission becomes binding.
Supported stablecoin submissions are converted to dollars, and refunds arrive in dollars.
Bitget's restriction says users cannot cancel submitted commitments or trade, transfer, or withdraw locked funds. Its fee is charged by the partner fund, broker, or placement channel and is included in the commitment.
The venue expects remaining funds to be refunded within hours of allocation confirmation, while warning that arrival can be delayed and processing extended if issuance or allocation arrangements fail.
Bitget's published VIP window was scheduled to end Nov. 11, while its public window is scheduled to end at 08:00 UTC on the day before the IPO.
The higher VIP fee does not remove allocation uncertainty, and the expected three-to-five-working-day delivery means those tokens may arrive after the stock's first trading day.
BigONE's window runs through Nov. 18 at 12:00 UTC. Its notice promises refunds if the platform receives no allocation, plus 6% annualized compensation for the time each subscription's funds were committed.
Payments below 1 $USDT per subscription are excluded, and the payment schedule will be announced separately.
The premium for tokenized Anthropic stocks
Using the preliminary range's $78 upper endpoint as an illustration, a 5% surcharge yields an acquisition cost of $81.90 per unit, while a 12% surcharge yields $87.36.
Assuming a token tracks one share without price divergence, the underlying price would need to rise 5% or 12%, respectively, from $78 just to match those acquisition costs, before any later trading charges.
The next decisive information for subscribers is the allocation received, when tokens become available, and when unused money returns.
Kraken says unallocated funds return on listing day, BigONE expects ANTx delivery on Nov. 19, and Bitget targets rANT trading about an hour after Anthropic's Nasdaq IPO Cross, while its VIP delivery expectation extends several working days beyond the IPO.
