AI’s contribution to US stock market wealth: $8.5 trillion

$8.5T

Analysts at consulting firm Pantheon Macroeconomics estimate that the stock market’s enthusiasm for all things AI has added some $8.5 trillion to aggregate US household wealth since late 2022. They wrote:

“The S&P 500 returned about 70% between the start of ChatGPT mania around the end of 2022 to the end of Q2 2025, with roughly half of those returns generated by the ‘magnificent seven’ tech stocks, a very rough proxy for the stock market boost from AI euphoria.

We estimate that translates into a lift to household wealth held in stocks of about $8.5T.”

As my colleague Luke Kawa recently wrote, stock market wealth seems to be underpinning US consumer spending, especially among the richest Americans. Some of that spending may retrench if AI is indeed a bubble — as some have recently mooted — and eventually pops.

Investors just made a mammoth $133 billion flip from cash to stocks, per Goldman Sachs

It’s a dash from cash, with investors taking billions in dry powder and pouring that money into the stock market.

“We saw strong net flows into global equity funds last week, led by stronger inflows into US and EM equity funds (+$71 billion vs $2 billion in the previous week) — more than 35x-ed the flows,” wrote Goldman Sachs’ Gail Hafif, Brian Garrett, and Lee Coppersmith. “While equity flows increase, money market fund assets fell by $62 billion. This is the 3rd largest level in our dataset (!).”

The trio is bullish on US stocks, seeing “the case for contained selloffs coupled with relief rallies as the most likely path forward in the near term.”

Moderna extends rally on positive cancer vaccine results

Moderna has more than doubled since it announced on Tuesday that its cancer vaccine reduced the risk of relapse or death for melanoma patients.

The five-year data from a Phase 2b trial showed that Moderna’s vaccine, when used with Merck’s blockbuster treatment Keytruda, reduced the risk of recurrence or death by 49% compared with Keytruda alone. The news gave investors hope that Moderna, which is best known for quickly developing a COVID-19 vaccine, may soon have another lucrative product in its portfolio.

Last week, Moderna said it expects to report total 2025 revenue of $1.9 billion, on the high end of its latest guidance of between $1.6 billion and $2 billion, amid better-than-expected vaccination rates. As demand for the COVID-19 vaccine, its sole revenue-generating product, has tanked, the company has aggressively cut costs and focused on expanding its portfolio.

The combination of positive announcements early in the year has made Moderna the second-best performer in the S&P 500 Index in 2026, behind newfound AI darling Sandisk.

POET Technologies tumbles after announcing $150 million direct share offering

POET Technologies is tumbling in early trading Thursday after the optical communications company announced that it’s raising $150 million through the sale of about 20.7 million shares in a registered direct offering.

It’s an opportunity for management to cash in on the stock’s more than 30% rally year to date (as of Wednesday’s close).

“With a substantial base of cash, we plan to accelerate our pursuit of targeted acquisitions, add to our capabilities and talent base, vertically integrate our products with differentiated components, and expand operations to pursue revenue opportunities across the board, in order to bring long-term value to shareholders,” Executive Chairman and CEO Dr. Suresh Venkatesan said.

POET’s last offering came in late October, after which shares nearly halved in less than a month amid a broad drawdown in speculative, volatile stocks beloved by retail traders.

Oracle gains amid report that the TikTok deal is poised to close this week

Oracle is gaining in premarket trading as Semafor reports that China and the US have signed off on the sale of TikTok’s US operations to a consortium in which the software giant is one of the three leading investors.

The transaction is poised to close this week, per the report, citing people familiar with the situation.

In mid-December, Oracle booked a huge gain after the CEO of TikTok owner ByteDance indicated that he’d signed contracts with Oracle and the other major investors leading this consortium, private equity firm Silver Lake and Abu Dhabi-backed tech investment company MGX.

If, as previous reporting suggested, the transaction values TikTok’s US operations at about $14 billion, that would mark a fairly low price tag for a lot of eyeballs and ad dollars. This pact will also afford Oracle’s cloud business an opportunity to deepen its preexisting relationship with TikTok.
