AXT, T1 Energy and Babcock & Wilcox Jump as AI Capex Spreads
Three stocks tied loosely to artificial-intelligence spending — an optics materials supplier, a domestic solar developer and an energy equipment maker — outran a softer tape on Friday.
AXT Inc (NASDAQ: AXTI) rose 3.81% to $80.40, T1 Energy Inc (NYSE: TE) gained 9.39% to $5.24 and Babcock & Wilcox Enterprises Inc (NYSE: BW) climbed 11.44% to $10.42 on Friday, 14 August 2026, as all three major US benchmarks traded lower.
Three stocks with no obvious connection to one another ran hard on Friday while the broad market drifted lower. AXT Inc (NASDAQ: AXTI) traded at $80.40, up 3.81% on the day from a prior close of $77.45. T1 Energy Inc (NYSE: TE) changed hands at $5.24, up 9.39% from $4.79. Babcock & Wilcox Enterprises Inc (NYSE: BW) was the strongest of the group at $10.42, up 11.44% from $9.35. All figures are as of the last trade at 16:26 GMT on 14 August 2026, with the market still open.
The tape they were outrunning was not helpful. The S&P 500, via SPY, was at $776.73, down 0.15%. The Nasdaq 100 tracker QQQ sat at $729.99, off 0.28%. The Dow 30 proxy DIA was at $536.74, down 0.22%. In other words, none of these three moves was a rising-tide effect. Something specific was pulling each one.
The common thread is spending, not products
As 24/7 Wall St framed it, these are second-derivative artificial-intelligence plays, with AI capital expenditure as the connective tissue. That phrase is worth unpacking, because it describes a widening category rather than a single trade.
A first-derivative AI stock sells the thing itself: the accelerator, the model, the cloud instance. A second-derivative name sells something the first group has to buy in bulk before it can ship anything — the substrate under an optical component, the electricity a data centre draws, the boiler or heat-transfer equipment that keeps a generating asset online. Those businesses do not need to win an AI product cycle. They need order books to fill up because someone else is spending.
That distinction matters for how these moves should be read. Second-derivative exposure tends to be lumpier and later than the headline AI names. It also tends to be cheaper going in, which is exactly why it attracts flows when the leaders stall — and QQQ down 0.28% on the session is the definition of leaders stalling.
AXT rides an optics rally, then hands some of it back
AXT was moving alongside a broad rally across optics names. The company supplies compound semiconductor substrates, the specialist wafer material that sits underneath optical and radio-frequency chips rather than the logic silicon most investors picture when they hear “semiconductor”. Optical transceivers inside data centres are one of the clearest bottlenecks in AI buildouts, because moving data between racks at speed is a physical problem, not a software one. When the optics complex rallies, substrate suppliers get pulled along with it.
The intraday pattern is the interesting part. AXT touched $85.43 at the high and traded as low as $76.75, meaning the stock was up roughly 10.3% versus Thursday’s close at its best point — an illustrative calculation from the quoted high and prior close — before settling back to a 3.81% gain. A stock that gives back more than half of its advance while still finishing well up is usually telling you the buying is thematic rather than company-specific. There was no earnings release or guidance change in the facts driving this; there was a group move, and AXT was in the group.
T1 Energy and the policy trade
T1 Energy’s 9.39% gain, to $5.24 from $4.79, was attributed to the domestic solar policy trade. This is a different mechanism from the optics rally. Solar developers and domestic module manufacturers live or die on the terms of federal support — content requirements, credit transferability, tariff treatment of imported cells. When the policy read shifts in favour of US-based production, the equities repriced hardest tend to be the smaller, higher-beta names, which is what a stock trading in the $5 range is.
The AI link here is power. Data centres need firm, growing supply, and utility-scale generation projects have become a way to sell into that demand without touching a chip. That gives solar developers a second demand narrative layered on top of the policy one — and when both point the same way on the same morning, a 9%-plus session in a low-priced stock is not surprising.
Data centres need firm, growing supply, and utility-scale generation projects have become a way to sell into that demand without touching a chip.
The day range, $4.81 to $5.39, shows the move held: the stock spent the session in the upper part of its range rather than fading. That is a marginally more durable signature than AXT’s.
Babcock & Wilcox and a fresh institutional disclosure
Babcock & Wilcox posted the largest percentage gain of the three, up 11.44% to $10.42, on attention around a new institutional disclosure. Filings that reveal a sizeable position taken by a professional investor act as a signal event for small and mid-cap names, particularly ones with complicated balance sheets. The stock does not change; the perceived shareholder base does.
The company builds and services energy and environmental equipment — the plumbing of thermal power generation. Grid capacity has become one of the hardest constraints on data centre expansion, which puts equipment and service providers in the second-derivative bucket alongside the solar developers. Whether that thesis converts to earnings is a separate question from whether a filing moves the shares on a Friday.
The price action was tight and constructive: a day range of $9.57 to $10.44, with the last trade at $10.42 sitting essentially at the high. Closing on the high after a double-digit percentage move suggests buyers were still working at the end of the session rather than taking profits.
What separates a rotation from a rerating
Three points are worth holding onto. First, none of these three moves rests on new financial results. One is a group rally, one is a policy read, one is a filing. All three are catalysts that can reverse without any change in the underlying business.
Second, the fact that all three ran while SPY, QQQ and DIA were all negative is the most informative single detail on the day. Money was rotating, not arriving. That kind of flow is real, but it is also fickle — it moves back out with the same speed if the AI leaders resume working.
Third, size matters to interpretation. A stock at $5.24 and a stock at $80.40 do not require the same amount of buying to move double digits. T1 Energy’s 9.39% and Babcock & Wilcox’s 11.44% are impressive percentages on small bases; AXT’s 3.81% on a considerably higher share price, from a group move that also produced an $85.43 print, may represent the larger absolute flow.
What to watch next: whether the optics complex holds its bid into the following week, whether the solar policy read produces anything concrete rather than anticipated, and whether Babcock & Wilcox’s new holder builds further. Absent those confirmations, Friday was a rotation day for the AI supply chain’s second tier, not a rerating of it.

Frequently asked questions
How much did AXT, T1 Energy and Babcock & Wilcox rise on Friday?
As of the last trade at 16:26 GMT on 14 August 2026, AXT Inc was at $80.40, up 3.81% from a prior close of $77.45. T1 Energy was at $5.24, up 9.39% from $4.79. Babcock & Wilcox Enterprises was at $10.42, up 11.44% from $9.35. The market was still open at that time.
What does ‘second-derivative AI play’ mean?
It describes a company that does not sell artificial-intelligence products itself but supplies something the AI buildout consumes in volume — substrate materials, electricity generation, power equipment. These businesses benefit from other companies’ capital spending rather than from winning an AI product cycle, which usually makes their revenue lumpier and later-arriving.
Why was AXT moving higher?
AXT was trading up alongside a broad rally across optics names. The company supplies compound semiconductor substrates used beneath optical and radio-frequency chips, and optical transceivers are a recognised bottleneck in data centre construction. The move was thematic rather than driven by any company results, and the stock gave back part of its intraday advance from a high of $85.43.
What drove the gain in T1 Energy shares?
T1 Energy’s 9.39% rise to $5.24 was attributed to the domestic solar policy trade — a shift in the read on federal support for US-based solar production. Smaller, lower-priced developers tend to reprice hardest on policy news. The stock spent the session in the upper part of its $4.81 to $5.39 range.
Why did Babcock & Wilcox jump 11%?
Attention centred on a fresh institutional disclosure — a filing revealing a professional investor’s position in the stock. Such filings act as signal events for smaller companies because they change the perceived shareholder base rather than the business. The last trade at $10.42 was essentially at the day’s high of $10.44.
Were these moves part of a broader market rally?
No. All three major US benchmarks were lower at the same time. SPY was at $776.73, down 0.15%; QQQ at $729.99, down 0.28%; and DIA at $536.74, down 0.22%. That pattern points to money rotating within the market toward second-tier AI supply chain names rather than fresh capital arriving.
