GIG heads into a pivotal week with a shareholder vote on its proposed merger with Hadron Energy scheduled for May 7 — and the sponsor moving to shore up support through non-redemption agreements.
The headline development is structural. GigCapital7's sponsor entered non-redemption agreements with select stockholders covering $19.3 million worth of shares, committing those holders not to redeem ahead of the vote. The SEC cleared the Form S-4 registration on April 15, formally opening the path to the merger. Days later, Hadron Energy signed a non-binding memorandum of understanding with Smartland Energy to explore deploying its Halo micro-modular reactor technology across five Smartland projects — a deal designed to demonstrate commercial momentum before the vote. With the clock ticking, this week is essentially a referendum on whether the SPAC can close the deal without a wave of redemptions undermining the transaction.
Positioning in the lending market tells a straightforward story: there is almost no short pressure here. Short interest amounts to just 0.4% of the free float — a level so thin it carries little analytical weight. Borrow availability is extreme in the other direction, at over 3,100% of short interest, meaning there are more than 31 shares available for every one already borrowed. Cost to borrow is a modest 5.25% — it drifted higher from roughly 4.2% in early April but remains well below the spike to 10% seen in mid-March. The short score of 30.2, while nudging up over the past week, sits in the lower half of the universe at the 44th percentile. None of this signals any meaningful bearish conviction from short sellers.
The sharp jump in shares short — up 10.5% in a single session on April 30 to approximately 46,900 shares — looks mechanical rather than directional. The absolute position is tiny for a stock with a $214 million market cap, and availability remains vast. This looks like routine SPAC arbitrage positioning ahead of the vote, not a structural short thesis.
The institutional register reflects the classic SPAC arb setup. GigAcquisitions7 Corp holds nearly 30% of shares, with hedge funds clustered across the cap table — Tenor Capital, Highbridge Capital (which took a fresh position worth its entire current stake in Q4 2025), Citadel, D.E. Shaw, and AQR all present. Several of these names are known SPAC arbitrage players. Highbridge and Harraden Circle both initiated new positions late last year, each adding their full current stakes in that period. The concentration of arbitrage capital suggests the market is treating this primarily as a redemption-or-close trade.
The price has been stable, closing at $10.70 on May 1 — up 0.5% for the month and essentially flat on the week. For a SPAC holding near trust value, that steadiness reflects the arb floor rather than any particular view on Hadron's underlying business. The next event to watch is the May 7 shareholder vote and the redemption outcome: the volume and composition of redemptions will determine how much cash survives into the combined entity, and whether the Smartland MOU translates into anything binding will matter for post-merger sentiment.
