SpaceX's $20 billion bridge loan, structured 18 months with two three-month extension options, was reported on April 23 as a refinancing taken on ahead of a confidential S-1 filing — and a six-month trigger that requires the company to either complete the IPO or refinance the bridge. Saturday is week three of the filing watch; nothing has hit EDGAR. [1]

The paper covered the bridge structure on April 30 when SpaceX collapsed the X and xAI debt stack into a single twenty-billion-dollar facility, framing the move as the moment SpaceX's optionality on staying private ended. Polymarket's "SpaceX IPO before July" contract was at 74% YES at week three, essentially unchanged from week one — a market view that the filing comes but slips toward late June or early July rather than early May. [2]

What the watch is testing is whether the Cerebras roadshow opening Monday at a $40 billion target sets a tone that helps or hurts the SpaceX bookbuild. Cerebras priced upward of the secondary-market mark in a docket-and-prosecutions environment; if it clears, the precedent is favorable. If it stalls, SpaceX's $1.75 trillion target — which would be the largest IPO in history — runs into a market with already-weak issuance appetite. [3]

The structural fact is unchanged. The bridge loan committed Musk to a public exit. The optionality is gone; only the timing remains. Watch the Federal Register Monday for any amendment to confidential filing status, and EDGAR Tuesday-Wednesday for an S-1 cover. If neither moves, the late-June scenario hardens. [4]
