SEC filing details cash creations and 10,000-share baskets
According to the preliminary prospectus, shares will be issued and redeemed in blocks of 10,000 known as Baskets. The trust is currently set up for cash creations and redemptions in which an authorized participant submits cash and an independent liquidity provider sources or delivers AVAX.

The index methodology in the registration statement references a CoinDesk AVAX reference rate calculated at 4:00 p.m. New York time on each business day for determining the basket amount in U.S. dollars. The trust highlights that this index is used for operational calculations and is not part of the trust’s financial statements.
Nasdaq 19b-4 application remains pending before effectiveness
The S-1 explains that Nasdaq filed a Rule 19b-4 application with the SEC on March 27, 2025 to list the trust’s shares and that the offering will not proceed unless this application is approved or generic listing standards are otherwise established to permit listing.
The filing cautions that there is no assurance on the timing or outcome of the 19b-4 process and that the information is subject to completion.
The prospectus further notes the trust is not registered under the Investment Company Act and the sponsor believes it is not a commodity pool under the Commodity Exchange Act.
The document emphasizes the risks associated with digital asset volatility and the evolving regulatory environment and clarifies that investors in the trust obtain exposure to AVAX price movements without directly holding AVAX.
If approved, the shares would be sold on a continuous basis at prices influenced by AVAX and secondary market trading on Nasdaq. The trust intends to register an indeterminate number of shares, with sales at varying prices determined at the time of each transaction.
At the time of press, the price of Avalanche (AVAX) is $24.24, showing a decrease of $0.88 (-3.51%) from the previous close
