"Owning SPCX equity and SpaceX bonds isn't diversification," he told CNBC. "It's the same execution risk across two instruments." At the portfolio construction level, his firm aggregates all SpaceX positions — debt and equity alike — into one concentrated exposure, applying the same framework it uses for any single-name technology holding no matter how it is packaged across asset classes.Underlying both instruments is an identical set of operational prerequisites — the success of Starlink's subscriber growth and Starship's development program — meaning a stumble in either would damage the investment case for stock and bond holders in equal measure, according to the outlet.Julian Howard, multi-asset head at Gam, pointed to a related structural tension, telling CNBC that nearly all investors already hold allocations to U.S. technology, and that the purpose of bonds as an asset class is to diversify. The 10-year tranche, he observed, carries a spread of just 1.4 percentage points above comparable Treasuries — thin enough that any shortfall against the company's revenue projections, or a broader deterioration in appetite for technology and AI names, could push that premium meaningfully wider.The question of diversification emerged within a fortnight of SpaceX completing its debut $25 billion bond sale, a transaction that attracted order books approaching $90 billion and was structured across five maturities stretching out to 2056, according to the outlet. The sale came shortly after the company's IPO on June 12, meaning many investors now hold SpaceX exposure across two asset classes simultaneously.Taken on their own, Della Fave said, the loss figures and elevated spending are not cause for immediate alarm — heavy cash consumption is a familiar feature of companies at SpaceX's stage of development. What he found notable was the sequence of events: the company moved into bond markets almost immediately after its IPO — which Della Fave described as the largest in history — at a moment when its books showed a $5 billion net loss and capital spending that had surged to more than double the prior year's level, according to the outlet.Terms and Privacy PolicyEU DSA contactPrivacy & Cookie SettingsMore Info
