Anthropic listing could draw early index-fund buying, research firm estimates
Research firm Intropic estimates index-fund demand for Anthropic shares could be large soon after next week's expected IPO, though SpaceX's similar post-listing rally has mostly faded.
Quick Read
- Research firm Intropic estimates Anthropic could draw large index-fund demand soon after its expected IPO next week, Reuters reported.
- New rules let giant companies join major indexes within days or weeks of listing, and funds tracking those indexes are required to buy.
- SpaceX shares rose sharply after their June IPO, but most of those gains have since faded.
What did the research firm estimate?
London-based research firm Intropic estimates Anthropic could attract $19 billion in demand from funds that track stock indexes, Reuters reported Thursday.
Why it matters: That buying could arrive soon after Anthropic's expected IPO next week. An IPO, or initial public offering, is a company's initial sale of shares to the public. After it, the stock trades on an exchange.
Why would index funds buy so quickly?
New rules let very large companies enter major indexes soon after listing. Funds that track those indexes are then required to buy the shares.
That creates a known buyer on a known schedule. Hedge funds can buy ahead of the index funds, hoping to sell later.
What happened with SpaceX?
SpaceX offers the closest recent comparison. Its shares rose sharply in the days after its June IPO, then gave back most of those gains.
On Thursday, SpaceX stock edged up 0.1% to $139.94. It then rose 1.4% to $141.96 in after-hours trading.
SpaceX now has a market value of $1.9 trillion. It accounts for 2.1% of the value of the 500 largest U.S. companies. Its Thursday gain added $3 to $100,000 spread across them by size.
What comes next?
What’s next: The open question is whether index buying lifts Anthropic shares for long, or fades as the SpaceX rally did. The answer may start to show in the listing itself, expected next week, and in the timing of any index entry.
For readers
What it could mean for you: If your 401(k) or IRA holds an index fund that adds Anthropic, that fund could become a buyer within weeks of the listing. Your fund would hold Anthropic in proportion to its size, so the stake may be small at the start. The price your fund pays could be higher if hedge funds have bought ahead of it. The SpaceX pattern shows that a quick rise after listing may not last, which could matter for what an index fund ends up paying.
Questions and answers
Why would index funds buy Anthropic shares soon after its IPO?
New rules allow giant companies into major stock indexes soon after listing. Index funds are built to mirror their index, so each new member becomes a required purchase for them.
Did SpaceX stock keep its gains after its IPO?
No. SpaceX shares rose sharply in the days after the June IPO, then lost most of those gains.
When is the Anthropic IPO expected?
The listing is expected next week. Intropic's estimate of index-fund demand, reported by Reuters on Thursday, assumes that timing.
