US midterm elections: Key Senate, House races investors are tracking

Wall Street and financial market participants are keeping a close watch on this year's U.S. midterm elections for reasons beyond simple control of Congress.

A small number of highly competitive races could decide the fate of some of the financial sector's key allies and opponents, while also shaping future policy surrounding cryptocurrency, credit card fees, financial oversight, and the ongoing investment surge in artificial intelligence.

The impact reaches well beyond legislative activity in Washington.


As reported by Reuters, a victory in either chamber of Congress would provide Democrats with robust investigative powers to probe financial institutions and their regulatory bodies. At the same time, several key gubernatorial elections could determine the trajectory of trillions of dollars slated for artificial intelligence infrastructure.

According to market analysts and industry executives, these are the key midterm contests investors and financial firms are tracking closely:

Ohio Senate race: Senator Jon Husted vs. Sherrod Brown

Sherrod Brown, a longtime Democrat and prominent critic of Wall Street and cryptocurrency, is attempting to win back a seat in the Senate after his loss in 2024. He is running against Republican Senator Jon Husted, who took over former Senator JD Vance's seat when Vance assumed the vice presidency.

Crypto advocacy groups have poured over $50 million into campaigns targeting Brown, turning this matchup into a high-stakes demonstration of the industry's political influence.

Brown previously served 18 years in the Senate. Should Democrats gain control of the chamber and honor his past tenure with senior status, he could potentially reclaim the chairmanship of the Senate Banking Committee, giving him direct oversight of financial regulators, or take on a leading role on the Agriculture Committee, which handles certain crypto regulations. Either position would provide him a powerful platform to scrutinize both sectors.

Polling indicates Brown holds a lead of up to 5 points or remains tied, while prediction markets as of Friday assigned him a 69.5% probability of winning.

Kansas Senate race: Senator Roger Marshall vs. Adam Hamilton

Although Kansas is not traditionally viewed as a battleground state, shifting political dynamics have turned Republican Senator Roger Marshall’s reelection campaign against Democratic challenger Adam Hamilton into a tight contest.

Even though Wall Street generally aligns with Republicans due to their preference for deregulation and lighter oversight, Marshall has actively pushed for caps on bank "swipe fees" for credit card transactions.

Major banks have long resisted these fee caps to safeguard their margins, voicing concern over how the topic has emerged as a rare point of bipartisan consensus.

A recent poll shows Hamilton holding a slight edge, whereas prediction markets on Friday gave Marshall a 55% chance of victory.

Texas Senate race: James Talarico vs. Ken Paxton

Ranked among the most expensive Senate battles in U.S. history, the neck-and-neck race between conservative Republican Attorney General Ken Paxton and Democrat James Talarico serves as a major test of whether Democrats can gain traction in traditionally red strongholds. A win for Talarico would mark the first statewide Democratic victory in Texas in decades.

Paxton has established a contentious history with Wall Street, repeatedly taking action against financial institutions and asset management firms he accuses of harboring "woke," left-leaning investment strategies. He has spearheaded multistate inquiries and filed lawsuits against major financial institutions over their environmental and diversity policies.

Recent polling places Talarico ahead by 2 to 8 percentage points, with prediction markets on Friday giving him a 66.8% chance of winning.

Nebraska Senate race: Senator Pete Ricketts vs. Dan Osborn

In another close Midwestern contest, Republican Senator Pete Ricketts faces independent candidate Dan Osborn. Sitting on the Senate Banking Committee, Ricketts has championed pro-crypto legislation, leading crypto industry groups to fund his campaign efforts, according to Politico.

Ricketts also maintains personal ties to high finance, having sat on the board of TD Ameritrade, a firm established by his father. Conversely, Osborn, a former labor union leader, has denounced credit card swipe fees as a "scam" that places unfair burdens on local communities and small business owners.

Polls show the candidates locked in a toss-up, though prediction markets on Friday favored Ricketts with a 71.7% chance of winning.

Gubernatorial races shaping AI investment

Growing public resistance to new data center developments has emerged as a key issue this election cycle, raising concerns that a strong showing by Democrats could slow down the infrastructure expansion that has buoyed stock valuations.

Because state and municipal leaders hold authority over land permitting and zoning for data centers, investors are paying extraordinary attention to state-level elections. Analysis from Beacon Policy Advisors highlights 10 upcoming gubernatorial races that will directly affect the direction of $2.5 trillion in planned capital expenditure.

Beacon identified Texas, Georgia, and Ohio as the most contested state races where candidates express starkly different policy approaches and where significant project pipelines exist. Analysts at Morgan Stanley similarly pointed to those three states, alongside Pennsylvania, Nevada, Wisconsin, and Michigan, as crucial elections to monitor.

House financial services committee races

Representative French Hill, an Arkansas Republican and former banking executive, currently leads the House Financial Services Committee, overseeing financial regulatory bodies and key industry legislation. Hill, known for advocating bank-friendly policies, faces a challenging reelection effort against Democratic challenger Chris Jones. The Democratic Congressional Campaign Committee recently listed Hill’s seat among its top targets to flip.

Another race closely followed by the crypto sector pits Democratic Representative Sean Casten against Republican challenger Niki Conforti in Illinois. Casten has been an outspoken advocate for investigating the Trump administration's ties to cryptocurrency and pushing for stricter industry regulations. Reporting from Punchbowl News last month noted that Casten had considered challenging Representative Maxine Waters, the current ranking Democrat on the panel, for the leadership spot should Democrats take control of the House.
