Key Takeaways
- The upcoming U.S. mid‑term elections are roughly six weeks away, and analysts view this cycle as pivotal due to issues such as the Iran conflict, affordability concerns, and the rapid rise of artificial intelligence (AI).
- Prediction markets (Polymarket) currently give Democrats a ~60 % chance of sweeping both the House and Senate, which would shift the political landscape dramatically.
- If Democrats gain control, the author’s top trade idea is to short‑sell AI‑focused data‑center companies, anticipating a regulatory crackdown that could depress their share prices.
- Data centers are described as the “low‑hanging fruit” for AI regulation because they are essential to AI workloads, have become unpopular with the public, and already face state‑level restrictions (e.g., New York’s one‑year ban).
- Congressional Democrats are pursuing measures to curb tax advantages for data‑center builders—such as bonus depreciation and Opportunity‑Zone incentives—and to impose new taxes on large power users.
- Pure‑play data‑center firms (CoreWeave, Nebius) and hyperscalers (Amazon, Alphabet) are identified as the most vulnerable to these potential regulatory headwinds, though the author notes the sector would likely not disappear entirely.
The Mid‑Term Landscape Six Weeks Out
Ready or not, the mid‑term elections are now about six weeks away. Although we probably say this every two years, this year seems like a big one, with some pivotal issues at play, including the Iran war, affordability issues, and everything surrounding artificial intelligence (AI). Although recent mid‑term elections have shown how hard it is to predict outcomes, and polling seems less reliable these days, the Democrats have a strong chance of flipping both the U.S. House of Representatives and the Senate. As of this writing, Polymarket places the odds of a Democratic sweep at 60 %.
Why a Democratic Sweep Triggers a Short‑Sell Thesis on AI Data Centers
If the Democrats do sweep, I think the No. 1 trade would likely be to short sell AI data center companies, meaning investors would profit if their share prices fall. Here’s why. The author’s rationale hinges on the expectation that a Democrat‑controlled Congress would move swiftly to regulate the AI ecosystem, and that data centers represent the most accessible lever for such regulation.
Data Centers as the Low‑Hanging Fruit for AI Regulation
Whether it was rogue agents from OpenAI hacking into Hugging Face or former Anthropic AI researcher Jacob Coxon warning the public that AI could lead to human extinction, there has certainly been a growing movement to regulate AI or install some kind of guardrails. Historically, the government has been slow to regulate new technologies, such as ride‑sharing, social media, or crypto. There is also a divide over AI regulation, as the U.S. doesn’t want to fall behind other countries, such as China. But AI is also moving faster than any technology ever has, so I do think a Democratic‑controlled Congress could move more quickly to adopt regulations. The low‑hanging fruit is likely data centers, which are key to powering AI and have become unpopular among the public.
State‑Level Precedents: New York’s Ban and Congressional Tax‑Break Moves
Democrats have already taken action to ban or make it harder to build data centers. New York Governor Kathy Hochul instituted a statewide ban on data centers for up to one year in order to allow time for the state to implement a regulatory framework. There have also been efforts in Congress to introduce legislation to slow the development of data centers. Recently, Politico reported that a group of Democrats proposed a bill to prevent data centers from taking advantage of certain tax breaks, such as bonus depreciation or benefits from building in Opportunity Zones.
Understanding the Tax Incentives Under Siege
Bonus depreciation lets builders deduct significant depreciation costs upfront that would normally be spread over the asset’s useful life, which can be many years. Opportunity zones let developers reinvest capital gains in designated areas considered more economically stressed in exchange for significant tax breaks. These include deferring the payment of capital gains taxes. Furthermore, if one of these investments in an opportunity zone is held for at least a decade, any subsequent capital gains are tax free.
Targeted Legislative Proposals from Virginia Lawmakers
A pair of Democrats from Virginia, U.S. Rep. Suhas Subramanyam and Sen. Mark Warner, have also recently sponsored legislation to further regulate data centers. Virginia has the most data centers in the country. Among other provisions, the bill would require states to create a tax on data centers and other large users of power infrastructure, so data centers would essentially cover the cost of new infrastructure required to power them.
Potential Market Impact: Nvidia, Pure‑Play Data‑Center Firms, and Hyperscalers
AI is powered by data centers, so if the Democrats did manage to flip Congress and impose more regulations or restrictions on data centers, that could slow the entire sector. For instance, Nvidia largely sells its graphics processing units (GPUs) for use in data centers. But the most directly affected stocks are likely pure‑play data center companies, such as CoreWeave (CRWV +5.00%) and Nebius. Furthermore, the hyperscalers such as Amazon and Alphabet are on pace to invest $1 trillion in AI infrastructure in 2025 and 2026, much of which has gone to build data centers. Still, these companies do have other tech businesses outside of AI.
Which Stocks Are Most Vulnerable?
Now, I’m not saying data centers are going away should the Democrats win Congress, but they are likely to face much more regulation, so if the Democrats do win, I expect the pure‑play data center companies and hyperscalers to sell off, at least initially. The author singles out CoreWeave and Nebius as pure‑play targets, while noting that Nvidia’s GPU sales are tightly coupled to data‑center demand. Hyperscalers, despite their diversified revenue streams, would also feel pressure because a sizable portion of their announced $1 trillion AI‑infrastructure spend is earmarked for new data‑center construction.
Conclusion: Anticipating an Initial Sell‑Off, Not a Sector Collapse
In summary, the convergence of a tightening political calendar, heightened public scrutiny of AI’s societal risks, and concrete Democratic legislative actions creates a plausible scenario where data‑center regulation accelerates. Should Democrats secure a sweep, the short‑sell thesis on AI‑linked data‑center equities gains traction, driven by the expectation of higher taxes, curtailed incentives, and possible operational restrictions. While the sector is unlikely to vanish, the near‑term market reaction could be a noticeable sell‑off in pure‑play data‑center stocks and a modest drag on hyperscalers’ AI‑related investments. Investors weighing the trade should monitor both the polling trends and the progress of the specific bills mentioned—particularly the New York ban extension, the Opportunity‑Zone tax‑reforms, and the Virginia‑sponsored power‑user tax—to gauge how quickly regulatory headwinds might materialize.
