SYDNEY, Friday, 19 December 2025 — Artificial intelligence-themed investing on the Australia stock market ended the week with a familiar mix of momentum and volatility: the S&P/ASX 200 closed up 0.47% at 8,628.20, led by a strong rebound in tech, while investors continued to debate whether the AI “build-out” is accelerating—or simply getting more expensive.

The local “AI stocks” story on the ASX today wasn’t just about pure-play AI developers. It was also about AI infrastructure (data centres, connectivity, energy) and AI-adjacent software—the parts of the market that typically move when global investors rotate in and out of high-growth themes. Technology was the standout sector, up 2.06%, even as the benchmark index ended a three-week winning streak with a small weekly decline. News.com.au
Below is a round-up of the major AI-related market moves, company headlines, and analyst forecasts available on 19 December 2025, plus what investors are watching next.
Australia stock market wrap: AI sentiment lifts ASX tech into the close
Friday’s price action looked like a textbook “risk-on” session for growth stocks: IT, financials and industrials led the gains, while implied volatility eased—an environment that typically supports higher-multiple tech names. Investing.com+1
By the close:
- S&P/ASX 200: +0.47% to 8,628.20
- ASX tech sector: +2.06% (sector leader)
- WiseTech Global (WTC): +3.15% to $70.18 (one of the day’s key tech drivers)
Market data providers also noted that the S&P/ASX 200 VIX fell 7.70% to 9.19, a new 52‑week low—another sign that investors were, at least today, comfortable adding risk.
WiseTech Global: governance clarity fuels a bounce in a heavyweight tech name
For many investors, WiseTech Global (ASX:WTC) sits in the “AI-adjacent” bucket—enterprise software where automation and AI features increasingly influence customer value propositions and margins over time. Today, however, the catalyst was corporate governance.
An internal review into allegations about co-founder Richard White, conducted by law firm Seyfarth Shaw, found “no evidence” to support claims of misuse of company funds in relation to certain individuals, according to an ASX announcement cited in market coverage. WiseTech shares were reported up around 2% during the session in that coverage, helping lift broader tech sentiment. ABC
A separate report also noted a new confidential complaint emerging after the independent review, adding that it was being handled internally, which kept governance questions in focus even as the stock rebounded.
Why it mattered for “AI stocks today” on the ASX: WiseTech is one of the market’s most influential local tech names. When it stabilises, it can improve sentiment across the broader software complex—even for smaller AI-linked stocks that trade more on theme than on near-term earnings.
AI defence and security: DroneShield leads the day’s ASX “AI movers”
One of the most eye-catching performances among AI-linked themes came from DroneShield (ASX:DRO), a counter‑drone technology name that markets AI-enabled detection and defence capabilities.
- DroneShield was flagged as one of the session’s best performers.
- End-of-day pricing data showed DRO at $2.78, up 11.65% at the close on 19 December.
DroneShield’s surge also featured prominently in broader market wraps highlighting “top gainers,” underlining how quickly thematic buyers can crowd into liquid mid-cap names when the tape turns supportive. The Economic Times
Investor takeaway: In Australia, “AI stocks” often rally hardest where the narrative is easiest to explain (security, drones, defence) and where incremental demand can move the price quickly.
AI infrastructure trade: data centres and the energy equation move back into focus
NextDC: AI tailwinds, but rate sensitivity and positioning still bite
The ASX has a clear AI infrastructure proxy in data centre operators, with NextDC (ASX:NXT) the most widely followed. But today showed the other side of that trade: these stocks can behave like “long-duration” growth assets and remain sensitive to positioning, rates and funding expectations.
Pricing data for NextDC showed:
- 19 Dec 2025 close: $11.94, down 2.85% on the day
That decline—on a day when tech as a sector rose—highlights the internal rotation within “AI stocks”: investors can favour software and higher-beta thematic names while trimming infrastructure exposures, especially after strong runs or when bond-market narratives shift.
Macquarie Technology Group: a second infrastructure beneficiary in focus
Macquarie Technology Group (ASX:MAQ), which includes data centre and cloud infrastructure exposure, traded firmer into the close.
- MAQ share price: $65.91, up 2.31% (as of 19 Dec 2025, delayed pricing)
The bigger catalyst: AI needs power—lots of it
The infrastructure conversation wasn’t only about racks and fibre. It was also about electricity—and the strategic value of securing it at scale.
One report said Google is exploring SunCable’s Northern Territory solar project for a potential giant AI data centre, describing it as a possible major global facility if it proceeds.
Separately, Reuters reported that Japan is planning what it described as its largest data centre hub, with a document pointing to a total capacity of 3.1 gigawatts to meet surging AI-related demand, and a first phase targeting 400 megawatts by late 2028.
Why this matters for ASX AI investors: the global AI boom is increasingly constrained by physical bottlenecks—power, land, approvals, and capex financing. Australian-listed data centre and digital infrastructure names sit close to that spending cycle, even when daily price action turns choppy.
AI “picks and shovels”: Appen, Ai‑Media and BrainChip on watch
Australia’s smaller AI ecosystem tends to cluster into three investable “mini-themes”: training data, edge AI chips, and AI-generated/AI-processed media.
Appen: training data veteran with a rebuilt bull case
Appen (ASX:APX) remains one of the most direct ASX exposures to the AI supply chain via data services.
Market data listed APX around $0.75 (as of 19 December).
What’s changed is not only the price—but the market’s willingness to re-rate the stock if demand stabilises. On forecasts, Investing.com’s consensus snapshot showed:
- Average 12‑month analyst target: A$1.19
- Implied upside: +59%
- Coverage: 4 analysts, with a “Buy” consensus rating Investing.com
Ai‑Media: AI captioning and speech tech with modest target upside
Ai‑Media Technologies (ASX:AIM)—often grouped into AI speech/translation and broadcast automation—was listed around:
- AIM price: $0.73, up 3.55% (Dec 19)
MarketScreener’s analyst snapshot showed:
- Average target price: $0.80
- Coverage: 1 analyst; consensus shown as Buy
BrainChip: high‑risk edge AI name with thin coverage and wide forecasts
BrainChip (ASX:BRN) is frequently cited as an ASX “edge AI chip” play, and its share price continues to trade at micro‑cap volatility levels.
Pricing data showed BRN around $0.16 on 19 December.
On forecasts, Investing.com’s consensus page (with only one analyst contributing) displayed:
- Average 12‑month target: A$1.144
- Implied upside: +615% (from a very low base)
Caution for readers: When coverage is thin, “consensus” targets can be misleading. Treat these numbers as a reference point for what one analyst/model suggests—not as a probability-weighted outcome.
The key risk signal from global markets: AI spending scrutiny is rising
While ASX tech rallied today, global analysis published on 19 December underscored a growing investor concern: who funds the AI capex wave, and at what price?
An Opto/CMC Markets report said private capital group Blue Owl reportedly pulled out of a $10bn deal to back Oracle’s next facility, framing it as a sign of caution around ballooning AI-related spending. The same piece described the facility as part of a broader infrastructure agreement with OpenAI and reported Oracle shares fell sharply on the headline.
Why it matters in Australia: even if Oracle isn’t an ASX stock, the broader message flows through to local AI infrastructure valuations. If global markets demand clearer returns on AI capex, it can pressure the multiples on data-centre and “AI capacity” plays everywhere—including the ASX.
Australia policy watch: copyright and AI training rules move (again)
Regulation is another swing factor for AI stocks, particularly those reliant on large datasets.
On 19 December, The Guardian reported the Productivity Commission abandoned a proposal that would have allowed AI models to mine Australian copyrighted material under a “fair dealing” style exemption, following significant backlash from creative industries. The report said the Attorney-General had rejected such an exemption earlier, and the Commission recommended waiting three years before reconsidering whether a broader review is needed. The Guardian
Market implication: For ASX-listed AI and AI-adjacent companies, tighter clarity on training-data permissions can cut both ways—potentially raising data access costs for model builders, while also reducing legal uncertainty and improving the outlook for licensing frameworks.
Analyst outlook: where forecasts see upside in ASX AI and AI-adjacent names
Below is a consolidated view of analyst targets and consensus snapshots available today (as published by market data providers). These are not guarantees—just what current coverage implies.
- NextDC (NXT): average 12‑month target A$20.60, “Strong Buy” consensus (15 analysts), with the stock shown at A$11.94 on the market-range line. Investing.com
- Macquarie Technology Group (MAQ): MarketScreener showed average target A$85.49 with an “Outperform” consensus and 8 analysts, versus a listed last close of A$63.79 on that page. MarketScreener
- Appen (APX): average 12‑month target A$1.19, “Buy” consensus (4 analysts). Investing.com
- BrainChip (BRN): average 12‑month target A$1.144 (1 analyst).
If you’re tracking the AI theme into year-end, it’s worth noting that at least one market strategist cited the potential for a seasonal “Santa Claus rally” dynamic in late December—one reason some traders are still leaning into tech beta as liquidity thins into the holidays. News.com.au
What to watch next for ASX AI stocks
The next catalyst set is likely to be macro-driven and global, but it will land on local tickers quickly:
- Evidence of AI spend discipline vs. acceleration
Watch for more funding headlines around hyperscale build-outs and large data-centre projects after the Oracle financing setback narrative. - Energy and site-selection deals
If Google’s reported interest in SunCable progresses, the market will read-through to Australia’s long-term attractiveness for AI infrastructure—particularly where renewable supply and fibre routes align. - Regulatory clarity on data and IP
The Productivity Commission’s pivot on copyright exemptions keeps the “rules of training data” debate alive, even if the near-term policy direction is more cautious. The Guardian
