Stock market today: Wall Street drifted into the final stretch of June as the AI trade wobbled into quarter-end. The US figures below are the close on Friday 26 June; the JSE and rand levels are as of this morning, Monday 29 June.

The setup

The dominant theme into quarter-end is a wobble in the AI trade. A New York Times report that OpenAI is weighing a delay to its IPO — pushing a potential listing to 2027 at a roughly $1 trillion valuation rather than coming to market lower now — lit a fuse under richly valued AI names and revived the question of whether the sector’s capital spending is sustainable. Chip stocks led the slide, dragging the Nasdaq to a fifth straight loss, while the S&P 500 closed essentially flat and the Dow barely moved as money rotated into defensive sectors. The damage was far heavier in Friday’s Asian session, so the key question into Monday is whether Wall Street and the JSE follow that lead.

Where the indexes stand

US moves are versus the prior close on Friday 26 June; JSE and FX levels are as of about 09:00 SAST, and free real-time prints vary.

What’s driving it

The catalyst was the OpenAI IPO-delay report, which renewed worries about the sustainability of AI capital spending and hit the most richly valued corners of tech hardest. Chip stocks bore the brunt of the selling:

• Micron fell more than 5%
• Sandisk dropped about 10%
• Marvell lost around 5%
• Arm fell roughly 4%
• Intel slipped about 3%

That pulled the Nasdaq to its fifth consecutive losing session. The selling was more severe in Friday’s Asian session, the epicentre of the move: SoftBank fell more than 12%, South Korea’s Kospi dropped about 6% (the Kosdaq around 4%) and Japan’s Nikkei lost roughly 4%. On Wall Street a rotation into defensive sectors offset much of the chip-driven damage, leaving the S&P 500 and the Dow close to flat even as the Nasdaq leaked lower.

Commodities and geopolitics

Commodities leaned risk-off alongside equities. Gold and the platinum-group metals pulled back, and a firmer US dollar added to the pressure — a combination that weighed on the rand and on the JSE’s mining heavyweights. There were no fresh top-tier geopolitical catalysts in the frame today; the dominant global risk driver remains the repricing of the AI trade and whether Friday’s heavy selling in Asia carries into this week’s sessions. For South African markets, the softer gold and PGM complex is the most direct channel, pressuring the resource counters that anchor the Top 40.

The macro picture

The rate backdrop stays hawkish. At its 17 June meeting, the Federal Reserve under new Chair Kevin Warsh held its policy rate at 3.50% to 3.75%, but the updated dot-plot flipped toward a hike, with the median now seeing rates ending the year higher and 17 of 18 officials flagging upside inflation risk. That overhang keeps pressure on rate-sensitive megacaps. The data calendar is light today: the second-tier Dallas Fed Manufacturing Index (around 16:30 SAST) is the only notable US print, alongside routine Treasury bill auctions near 17:30. In South Africa there is no top-tier scheduled release today; month-end private-sector credit, M3 and the SARS trade balance land on Tuesday 30 June, with the SARB repo rate at 7.00%. The rand, near a five-to-six-week low around 16.5 to 16.6, is being steered by the dollar, gold and the global risk tone rather than local data.

What the strategists are saying

The prevailing read among strategists cited by CNBC and others is “correction, not crash” — a valuation adjustment after a historic run that saw the S&P 500 climb nine straight weeks, rather than a fundamental breakdown. Rob Thummel of Tortoise Capital framed the selloff as “an opportunity to buy some really essential, critical AI infrastructure stocks at cheaper prices,” and the buy-the-dip camp still sees the S&P with “a real chance” at 8,000, echoing year-end targets near that level from Goldman Sachs and Morgan Stanley. The cautious camp counters that combined 2026 AI capital spending at Microsoft, Alphabet, Amazon and Meta now exceeds $452 billion, and questions whether AI monetisation justifies it — doubts the OpenAI IPO-delay report only sharpened. Bank of America stays hawkish on rates, and semiconductor ETFs such as SOXX bore the brunt of the selling, leaving the standing concern of narrow-leadership concentration risk in the AI megacaps that have driven index returns. These are others’ views, reported here for context.

On the radar

Today is quiet on scheduled data, so the live swing factor is tech-selloff follow-through. The bigger events cluster later in the week:

• US ISM Manufacturing and JOLTS — Wednesday 1 July
• US ADP private payrolls — Thursday 2 July
• US June jobs report / non-farm payrolls — around the 4 July holiday (likely Thursday 2 or Friday 3 July), the week’s highest-volatility print
• German flash inflation (Tuesday 30 June) and euro-area flash CPI (Wednesday 1 July)
• South Africa month-end private-sector credit, M3 and the SARS trade balance — Tuesday 30 June

Locally, the market is also digesting Naspers’ full-year results released today; the group pre-guided core headline earnings per share up 20.8% to 27.8% on revenue above $7.3 billion, with all its ecosystems now profitable.

Bottom line

Into quarter-end, the market is repricing the AI trade rather than abandoning it. A near-flat S&P 500 and Dow mask a fifth straight Nasdaq loss and a sharp, chip-led selloff that hit hardest in Asia. With a quiet data day, the immediate tell is whether Friday’s heavy selling follows through on Wall Street and the JSE — before this week’s ISM and US jobs data, a hawkish Fed and a softer rand set the tone for the second half of the year.
