Reading the filings
Arithmetic on what Horizon Space Acquisition I 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
The stated combination deadline of Mar 27, 2024 has passed without a closing in our filing record. Either an extension was approved that we have not yet indexed, or the vehicle is in wind-down. Check the latest proxy statement.
Sponsor record
Horizon Space has launched 2 vehicles. Of the 1 that have resolved, 0 closed a combination and 1 liquidated, a 0% completion rate. A sponsor's record is not a forecast, but it does tell you whether the team has taken a deal across the line before.
Underwriting
Maxim Group led the offering. It has been named on 31 SPAC IPOs, book-running 23 of them, and 28.6% of its resolved vehicles closed a deal. 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.

Edge reads the setup, not the business. A vehicle can score well on protection and still be a poor place to leave money once a deal closes.

Attention is not quality. FOMO rises on news volume and on the market paying above trust, both of which have preceded plenty of disappointments.

definitive agreement signed
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.

Horizon Space Acquisition I Corp.: questions answered
What is Horizon Space Acquisition I Corp. (HSPOF)?
Horizon Space Acquisition I Corp. is a special purpose acquisition company incorporated in Cayman Islands and registered with the SEC under CIK 0001946021. It completed its initial public offering in Dec 2022, raising $67.6M in gross proceeds and listing on OTC. Class A shares trade under the ticker HSPOF on OTC. The vehicle is sponsored by Horizon Space through Horizon Space Acquisition I Sponsor Corp. The mandate targets generalist. Definitive business-combination agreement signed, closing pending.
How much does Horizon Space Acquisition I Corp. hold in trust?
Approximately $753,670, 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 Horizon Space Acquisition I Corp. complete a merger?
By Mar 27, 2024. 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 Horizon Space Acquisition I 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 Horizon Space Acquisition I 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 Horizon Space Acquisition I Corp. trade under?
Class A shares trade as HSPOF on OTC. 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 Horizon Space Acquisition I 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.
Who sponsors Horizon Space Acquisition I Corp., and what is their track record?
Horizon Space Acquisition I Sponsor Corp is the sponsor entity, part of the Horizon Space franchise. That franchise has launched 2 vehicles in total, of which 0 closed a combination and 1 liquidated, a 0% completion rate on resolved vehicles.
Which banks underwrote the Horizon Space Acquisition I Corp. IPO?
Maxim Group, Financial, Network 1 Financial. Maxim Group and Network 1 Financial were credited as book-running managers on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Horizon Space Acquisition I Corp. tradeable, and where?
Yes. HSPOF returned a live quote of $11.99 on OTC. 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 Horizon Space Acquisition I Corp. a good investment?
That is not a question this site answers. Horizon Space Acquisition I 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 Horizon Space Acquisition I Corp. data come from?
Filings Horizon Space Acquisition I Corp. submitted to the SEC under CIK 0001946021: 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.
