Reading the filings

Arithmetic on what GigCapital8 Corp. has disclosed, written the way a desk would read it. These are observations, not a rating. Nothing here scores the vehicle or implies a view on it.

  • Time on the clock

    398 days to the Oct 7, 2027 deadline. The vehicle is early in its search window, and the deadline is not yet the binding constraint.

  • Underwriting

    D. Boral Capital led the offering. It has been named on 28 SPAC IPOs, book-running 27 of them. The syndicate has no control over whether a sponsor finds a target, but the quality of the book at pricing shapes who ends up holding the units.

Potential is about execution, not about the target. It says nothing about whether the eventual deal is worth owning, because the target is usually unknown when the score is computed.

These are derived measures, not ratings of investment merit. They carry no view on the target, no price target and no recommendation, and a high score is not a reason to buy anything.

GigCapital8 Corp.: questions answered

What is GigCapital8 Corp. (GIW)?

GigCapital8 Corp. is a special purpose acquisition company incorporated in Cayman Islands and registered with the SEC under CIK 0002080019. It completed its initial public offering in Oct 2025 and listing on Nasdaq. Class A shares trade under the ticker GIW on Nasdaq. The vehicle is sponsored by GigAcquisitions8 through GigAcquisitions8 Corp. The mandate targets technology, aerospace & defense, education. Definitive business-combination agreement signed, closing pending.

How much does GigCapital8 Corp. hold in trust?

Approximately $259,803,251, as at the most recent filing on record. Trust balances move: shareholders redeem at extension votes and at the combination vote, and sponsors pay contributions in to extend. Treat the figure as a point-in-time disclosure, not a running balance.

When must GigCapital8 Corp. complete a merger?

By Oct 7, 2027. If no combination closes by then the sponsor must seek a further extension or wind the vehicle up and return the trust.

What happens if GigCapital8 Corp. does not find a target in time?

The charter requires the vehicle to redeem 100% of the public shares and return the trust, pro rata, to public shareholders. That is the mechanism working as designed rather than a default. Founder shares and warrants are worthless in that outcome, which is why the sponsor's incentive is to get a deal done or to buy more time. Across the market, deadline lapsed without a deal; trust returned to public shareholders.

Can I redeem shares in GigCapital8 Corp., and at what price?

Public shareholders may elect to redeem in connection with a combination vote and at each extension vote, at the pro-rata trust value on the relevant record date. Redemption is a right attached to the public shares only; warrants and rights carry no claim on the trust. The mechanics and the deadline for electing are set out in the proxy statement for the vote in question.

What tickers does GigCapital8 Corp. trade under?

Class A shares trade as GIW on Nasdaq. Units trade first and separate into their component securities roughly 52 days after the IPO; only the Class A shares carry the redemption right against the trust.

Is the trust value the same as the share price for GigCapital8 Corp.?

No. Trust per share is a disclosed, contractual figure: what a redeeming holder receives. The market price is whatever the shares change hands at, which can sit above the trust when a deal is well received or below it when the market doubts one will close. We do not have a current quote for this vehicle, so no spread is shown.

How much dilution do GigCapital8 Corp.'s founder shares and warrants create?

Both are disclosed in the prospectus and both survive into the combined company, which is why a de-SPAC at $10 is not economically the same as an IPO at $10.

Who sponsors GigCapital8 Corp., and what is their track record?

GigAcquisitions8 Corp is the sponsor entity, part of the GigAcquisitions8 franchise. This is the only vehicle we have attributed to that sponsor. Named principals: Avi Katz.

Which banks underwrote the GigCapital8 Corp. IPO?

Webull Finanical, Bancroft Capital, Dominari, D. Boral Capital. D. Boral Capital was credited as book-running manager on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.

Is GigCapital8 Corp. tradeable, and where?

Yes. GIW returned a live quote of $10.19 on Nasdaq. Quotes here are delayed and refreshed on a schedule rather than streamed, so treat the figure as indicative and confirm on your own venue. Units and warrants trade under their own symbols and are quoted separately.

Is GigCapital8 Corp. a good investment?

That is not a question this site answers. GigCapital8 Corp. is covered here as reference data: what the company filed, when it filed it, and what the numbers in those filings say. The Edge, FOMO and Potential scores on this page are derived measures with a published formula, not ratings of investment merit: they describe the setup, and every component is shown so you can take them apart. We publish no price targets and no recommendations, and nothing here should be read as advice. The figures are a starting point for your own work, and each one carries the accession number of the filing it came from.

Where does this GigCapital8 Corp. data come from?

Filings GigCapital8 Corp. submitted to the SEC under CIK 0002080019: the registration statement and final prospectus for the structure, quarterly and annual reports for the trust, current reports and proxy statements for deals, votes and extensions. Trust economics are taken from the registrant's own XBRL tags rather than parsed from prose, which is why they are exact. Every filing in the history above is listed with its accession number, which identifies the document uniquely on EDGAR; Pro accounts open it directly from the row.

Compiled by the SPACListing research desk

Last reconciled Sep 4, 2026

Every figure on this page is read from documents the registrants filed with the U.S. Securities and Exchange Commission, principally the IPO prospectus (Form 424B4), quarterly and annual reports, current reports and proxy statements, the registrant's own XBRL tags for trust economics. Nothing is sourced from press coverage, from the companies themselves, or from a third-party aggregator. Where a filing does not disclose something, the field is left blank rather than estimated.
