SpaceX’s $1.75 Trillion Shadow Looms Over Gold-Rated iShares MSCI World ETF

iShares MSCI World ETF (URTH) earns Morningstar gold rating but faces headwinds from SpaceX's $1.75T IPO, fee competition, high US tech concentration, and Fed rate uncertainty.

Just as the iShares MSCI World ETF (URTH) was awarded Morningstar’s top gold medal, a far bigger story began to take shape behind the headlines. SpaceX, valued at $1.75 trillion, filed confidentially with the SEC in early April, with a Nasdaq listing expected this summer. The sheer size of that single IPO — on par with Apple, Microsoft, and Nvidia — will force URTH and other passive vehicles into an involuntary reshuffling of hundreds of positions. And SpaceX is not alone. OpenAI and Anthropic are eyeing listings by year-end, while a pipeline of venture-backed fintech, defence, and software companies waits for a market window.

Morningstar’s gold stamp, in place since 27 April 2026, compares URTH against 297 global large-cap blend products on risk-adjusted returns. Yet the accolade arrives in a market that has never been more hostile to fees. Invesco slashed the expense ratio of its own MSCI World ETF to 0.05 percent, a full 19 basis points below URTH’s 0.24 percent. UBS and BNP Paribas followed with cuts of their own. BlackRock counters with a tracking difference of just 0.02 percent — the best in its peer group and a key factor in Morningstar’s rating. So far, cost-conscious investors have not fled: net inflows over the past twelve months reached $1.86 billion, pushing assets under management to $8.25 billion.

The portfolio itself remains heavily tilted toward the United States, which accounts for 70.98 percent of the fund. Japan (5.67 percent) and the UK (3.82 percent) are distant seconds. The technology sector dominates at 25.59 percent, a concentration that exposes URTH to any shift in interest-rate expectations. Nvidia has swelled to roughly 6.4 percent of the fund after posting quarterly revenue of $81.6 billion — an 85 percent year-on-year jump that beat the $78.9 billion consensus. Apple and Microsoft sit at around 4.9 percent and 3.2 percent respectively. The broader MSCI World Index recently touched a record high, buoyed by an eighth consecutive weekly inflow of $39 billion into global equity funds and first-quarter earnings beats from 72 percent of index constituents.

Against that backdrop, the calendar is about to get dense. On 29 May, MSCI’s quarterly rebalancing adds Medline A, MasTec, and TechnipFMC, a modest tilt toward medical technology, infrastructure, and energy services. A free-float adjustment follows on 1 June, and the fund goes ex-dividend on 15 June with a $1.26 per-share payout. But the real uncertainty lies with the Federal Reserve. Kevin Warsh assumed the chair on 15 May after the narrowest Senate confirmation in the central bank’s history. US inflation sits at 3.8 percent – a three-year high – outstripping wage growth of 3.6 percent. Bank of America and Goldman Sachs have scrapped all rate-cut forecasts for 2026, and markets price a 97 percent probability of unchanged rates at the next meeting. Warsh has signalled openness to lower borrowing costs but insists on independence from political pressure; many read his early messaging as hawkish.

The more structural test for URTH, however, is the coming wave of mega-IPOs. MSCI permits accelerated index inclusion for listings of this magnitude, bypassing the regular quarterly cycle. Every debut will generate its own rebalancing event, forcing the fund to sell proportional slices of existing holdings to fund the compulsory purchases. That will push US weightings even higher and shift sector exposure toward aerospace, defence, and artificial intelligence. With a price-to-earnings ratio of roughly 25 and a dividend yield of 1.53 percent, the margin for error is thin. The gold medal recognises superior tracking, but it is the ability to absorb these unprecedented index flows — and the associated cost pressures — that will determine whether URTH keeps its lustre.
