OpenAI's board once refused to invest $500 million in Sam Altman's fusion startup. Now some shareholders are privately asking whether Altman is the right person to take the company public at all — and floating his successor.
The question of who leads OpenAI through an IPO is inseparable from a power contract the board approved instead. The Helion Energy purchase agreement gives OpenAI the right to buy electricity from a company Altman has backed since 2014 — structured as a power contract rather than an equity stake, a distinction that determines whether it shows up in IPO disclosure filings or not. Altman stepped down from Helion's board to let the deal proceed. The arrangement captures the upside of Helion's success without the related-party classification that would make it visible to investors filing an S-1.
The Helion deal was not small. Altman proposed that OpenAI commit roughly $500 million at a $35 billion valuation — roughly six times what Helion was worth fourteen months earlier, per BusinessToday citing the WSJ. The board said no. Without OpenAI's equity participation, Helion's raise scaled back from a planned $1 billion to $250 million at a $15 billion valuation. Altman then asked SoftBank — which was simultaneously closing a $40 billion investment in OpenAI — to invest in Helion separately. Masayoshi Son handled the Helion deal personally, per Livemint. Altman has also pledged his startup shares as collateral in a JPMorgan credit line to fund further bets, a structure invisible on an IPO disclosure form.
The Helion agreement would give OpenAI 12.5% of Helion's production: five gigawatts by 2030 and 50 gigawatts by 2035. Helion has said each of its reactors will generate 50 megawatts, meaning roughly 800 reactors by 2030 and 7,200 more by 2035 to hit those targets.
Altman earns a $66,000 salary at OpenAI and holds no equity in the company — a structure designed to prevent conflicts of interest. But IPO disclosure rules were written for a CEO with a direct equity stake in a vendor, visible on an S-1. A CEO whose personal portfolio benefits from a vendor relationship that avoids equity classification is harder to flag.
Some OpenAI shareholders have privately discussed whether Altman is the right person to steer the company through an IPO and have floated board chair Bret Taylor as a potential successor, according to Gizmodo. "Am I excited to be a public-company CEO? Zero percent," Altman told investors. "In some ways I think it'd be really annoying."
Whether the SEC develops the framework to catch conflicts that wear the costume of a power contract rather than a stake is the question that follows the IPO filing. If fusion power remains unproven, OpenAI will have locked in electricity from a supplier that cannot yet deliver it, a manageable problem for a private company. If it works, the question of who captured the value, and through what legal structure, is the one that doesn't go away.
