The Quick Answer
Democrat James Talarico leads Republican Ken Paxton 48% to 44% in a new AARP survey of the Texas Senate race released September 10, 2026. That is a sentence Texas Republicans have gone a long time without having to read. On Kalshi, the "Texas Senate winner?" market gives Talarico a 51% chance and Paxton a 49% chance as of 3:00 PM ET on Monday, September 14, 2026, which is about as close to a coin flip as a statewide Texas race gets priced. In a state that hands Republicans statewide offices almost every election, a price like that is less a read on the Democratic Party's revival and more a read on one Republican. The $51.3 million in TV ads that a GOP super PAC just dropped into Texas is the test of whether money can change it.

Does This Fit The Rest Of The Texas Polling
The AARP Texas survey was run by the bipartisan pair of Fabrizio Ward on the Republican side and Impact Research on the Democratic side, which interviewed 895 likely Texas voters statewide from August 30 to September 1, 2026, with a margin of error of plus or minus 3.3 points. That margin applies to each candidate's share on its own, and the uncertainty on the gap between two candidates in the same poll runs close to twice as wide, so Talarico's 4-point lead sits inside the margin of error. Read it as a race that may have tipped his way rather than one that has broken open.
The same survey contains its own counterweight. Among voters 50 and older, Paxton led 53% to 40%, a 13-point lead running in the opposite direction from the topline. AARP Texas State Director Lisa A. Rodriguez said older voters weigh "day-to-day realities like caring for an aging family member" when they vote.
Set that against the only other public Texas Senate poll we have in hand. Emerson College Polling surveyed 1,000 likely Texas voters on August 9 and 10, 2026, with a credibility interval of plus or minus 3 points, and found the race essentially tied at Paxton 47% to Talarico 46%. Emerson executive director Spencer Kimball said, "The race for U.S. Senate in Texas is sharply divided by age: voters under 50 favor Talarico by 15 points, 53% to 38%, while those over 50 break for Paxton by 11 points, 53% to 42%." The two polls disagree on the leader and agree on the shape, which makes the AARP result look like a close race sliding a point or two inside a pattern that was already there. Two polls is a thin trend line, and these are what has been released publicly.
That age split is also the clearest thing we can say about Talarico's position. His support sits with voters under 50, who broke for him by 15 points in Emerson's survey, and his standing with older Texans is the open problem on his side of the board.
The Money Says Republicans Are Worried
Through the fundraising period ending June 30, 2026, Paxton's two campaign committees had raised a combined $9.2 million and spent $7.5 million, leaving $1.76 million in cash on hand, according to FEC filings reported by Newsweek. Then, on September 10 and 11, the Senate Leadership Fund's affiliated Texas PAC bought $51.3 million in broadcast TV across Dallas-Fort Worth, Houston, San Antonio and Austin, ending months in which the Thune-aligned super PAC sat the race out.
Super PACs with $51.3 million to spend tend to spend it where the outcome is in doubt. A Senate Majority PAC spokesperson made exactly that point, saying Paxton had dragged the GOP super PAC into "bailing out a seat that was supposed to be sure-footed territory for the GOP." Spokesperson Christyna Thompson added, as quoted by KERA News on September 14, "They should be sweating."
What The Market Is Pricing
The most telling part of the Kalshi board is what the price leaves out. Texas has elected Republicans to statewide office consistently for decades, so a Republican nominee there would ordinarily trade as a clear favorite on the strength of the state alone. Paxton trades at 49%, which means the market is giving him essentially no credit for running in Texas. The polls explain why the race is close, and the price suggests traders place the reason for that closeness on the candidate rather than on a state that has suddenly turned competitive.
That sets up the cleanest test on the calendar. Paxton sits at 49% with the Texas PAC ads already on the air. If a buy that size cannot lift him back above an even chance over the coming weeks, the market is treating his ceiling as a problem with the candidate rather than a shortage of money. If his price climbs past Talarico's, traders are saying the seat was underfunded rather than slipping away.
What Comes Next
Two dated things are on the calendar. The Texas PAC buy that began September 10 and 11 runs through the fall, so its effect, if there is one, shows up in polling and pricing over the coming weeks. The next FEC reporting period after the June 30 filings will show whether Paxton's cash position recovered or stayed thin. Debate dates are not confirmed in the reporting gathered for this piece, so none appear here.
About The Numbers
Kalshi's chance figure reads as the market's rough probability that an outcome happens, so Talarico at 51% means traders price his party winning the seat at about a 51% chance, and the contract settles on which party wins. A margin of error of plus or minus 3.3 points means a repeat of the same poll would be expected to land within 3.3 points of each reported share most of the time. Because one candidate's share tends to fall when the other's rises, the margin on the lead between them is close to double, which is why a 4-point lead in this poll is inside the margin. "Likely voters" is the pollster's own screen for people expected to cast a ballot, and a crosstab such as the 50-and-older result covers a slice of that sample, with a wider margin than the full poll. Cash on hand is the money a campaign had left on the last day of the reporting period, which for these filings is June 30, 2026.
