The race remains genuinely open, decided by margins so narrow
As Colombia approaches its May 31st presidential vote, the contest between lawyer Abelardo de la Espriella and Senator Iván Cepeda Castro has become a study in how different instruments of democratic measurement can tell different stories about the same moment in history. Prediction markets, where money follows conviction, now tilt slightly toward De la Espriella, while traditional polls still favor Cepeda — a divergence that speaks less to confusion than to the genuine openness of a nation still deciding its direction. With no candidate likely to secure a first-round majority, Colombia appears headed toward a June 21st runoff, where the consolidation of the right-wing vote may prove the decisive force.
- Prediction markets flipped in just 48 hours, moving De la Espriella from trailing Cepeda to leading him by two points — a sign that electoral momentum is shifting in real time.
- Traditional polls and betting markets are pointing in opposite directions, creating a rare and unsettling split in the signals that campaigns, analysts, and voters rely on to read the race.
- No candidate is on track to win outright on May 31st, making the June 21st runoff the true battleground — and the math of who faces whom could determine everything.
- The right-wing electorate is visibly reorganizing: De la Espriella has displaced Valencia as the leading opposition figure, suggesting a consolidation that could prove decisive in a second round.
- Second-round modeling reveals a striking asymmetry — De la Espriella narrowly beats Cepeda in a head-to-head, but Valencia beats Cepeda more decisively, underscoring how fragile Cepeda's path to the presidency remains.
Colombia's presidential election, set for May 31st, is producing competing portraits of who holds the advantage — and the tension between those portraits is itself the story. On prediction markets like Polymarket, where traders wager real money on political outcomes, Abelardo de la Espriella of the Defenders of the Homeland movement now holds a 43 percent probability of winning, edging past Senator Iván Cepeda Castro of the Historic Pact coalition at 41 percent. Just two days earlier, Cepeda had been ahead. Senator Paloma Valencia of the Democratic Center trails both at 16 percent.
Traditional polling tells a different story. AtlasIntel's survey for Semana magazine places Cepeda at 38 percent of valid votes, with De la Espriella at roughly 30 percent and Valencia at 21 percent. A separate poll by the National Consultation Center for Cambio magazine similarly favors Cepeda at 37.2 percent, with De la Espriella at 20.4 percent. Both surveys agree on one crucial point: no candidate is positioned to win in the first round, making a June 21st runoff the most likely outcome.
The runoff scenarios are where the race grows most complex. If De la Espriella faces Cepeda one-on-one, the AtlasIntel modeling gives De la Espriella a narrow victory. But if Valencia advances instead of De la Espriella, she defeats Cepeda more decisively — suggesting that the right-wing vote, when consolidated, carries significant force regardless of which candidate channels it.
A notable shift has already occurred within that conservative space. Weeks ago, Valencia was seen as the primary opposition figure. That mantle has since passed to De la Espriella, signaling a quiet reorganization of the electorate's right flank. With the race entering its final stretch, analysts across the spectrum agree: the outcome remains genuinely open, and the divergence between prediction markets and traditional polls only deepens the uncertainty surrounding one of Colombia's most competitive presidential contests in recent memory.
Colombia's presidential race is tightening as voters prepare to cast ballots on May 31st, and the competing signals from different measurement tools are painting a portrait of genuine uncertainty. Prediction markets, which aggregate bets on political outcomes, now show lawyer Abelardo de la Espriella with a 43 percent chance of winning, edging out Senator Iván Cepeda Castro of the Historic Pact coalition, who sits at 41 percent. This represents a shift from just two days earlier, when Cepeda held a narrow lead at 42 percent to De la Espriella's 40 percent. Senator Paloma Valencia of the Democratic Center trails both at 16 percent in the prediction market calculus.
Polymarket, the international platform where traders essentially bet real money on political and economic events, has become an alternative barometer of electoral sentiment—one that operates on different logic than traditional polling. The market's recent movement suggests momentum has shifted slightly toward De la Espriella, the candidate of the Defenders of the Homeland movement, though the margin remains razor-thin.
Yet traditional surveys tell a different story. AtlasIntel's recent poll for Semana magazine shows Cepeda commanding 38 percent of valid votes, with De la Espriella at 29.9 percent and Valencia at 21.2 percent. This gap is substantial enough that it raises a fundamental question: none of these candidates appears positioned to win outright in the first round. Colombia is likely headed toward a runoff scheduled for June 21st. The AtlasIntel data also modeled potential second-round matchups. If De la Espriella and Cepeda face each other in a runoff, De la Espriella would win with 47 percent against Cepeda's 42 percent. But if Cepeda runs against Valencia instead, Valencia emerges victorious with 49.1 percent to Cepeda's 40.6 percent—a striking reversal that suggests the right-wing vote could consolidate differently depending on who advances.
A separate survey by the National Consultation Center for Cambio magazine reinforces the traditional polling picture, with Cepeda at 37.2 percent, De la Espriella at 20.4 percent, and Valencia at 15 percent. This poll also captured a significant realignment within Colombia's right-wing political space. Weeks ago, Valencia appeared to be the main opposition figure. That role has now shifted to De la Espriella, suggesting the conservative electorate is reorganizing around him as a potential alternative to Cepeda.
Other candidates—Sergio Fajardo, Claudia López, Santiago Botero, and Roy Barreras among them—remain far behind in both prediction markets and traditional polls. As the election enters its final stretch, political analysts are converging on a single assessment: this race remains genuinely open, and the outcome could hinge on margins so narrow that small shifts in voter sentiment or turnout patterns could alter the result. The divergence between prediction markets and traditional polling adds another layer of uncertainty to what is already shaping up as one of Colombia's most competitive presidential contests in recent memory.

La Conversación del Hearth Otra perspectiva de la historia
Why would prediction markets and traditional polls show such different pictures three weeks before an election?
They're measuring different things, really. Polymarket captures what people with money on the line actually believe will happen. Traditional polls ask people what they intend to do. Those aren't the same—one is a bet, the other is a stated preference. People might tell a pollster one thing and behave differently in the booth.
So which one is more reliable?
That's the question everyone's asking right now. Prediction markets have been surprisingly accurate in recent years, but they're also thin markets—fewer participants, potentially easier to move. Traditional polls have institutional weight behind them, but they can miss late-breaking shifts in voter sentiment.
The runoff scenarios seem crucial. Valencia beats Cepeda but loses to De la Espriella?
Exactly. It suggests the right-wing vote is fluid. If Cepeda makes it to a runoff against Valencia, the left consolidates and wins. But if De la Espriella gets there, he pulls enough votes from the center and right to beat Cepeda. The second round could look completely different from the first.
What does De la Espriella's recent momentum in the prediction markets actually mean?
It could mean sophisticated observers think he's gaining ground, or it could be noise—a small number of traders moving the needle. But the fact that he's moved from 40 to 43 percent in two days while Cepeda dropped suggests something shifted in how people are thinking about his chances.
Is there any candidate who seems genuinely locked in?
No. That's what makes this different. Even Cepeda, who leads in most traditional polls, can't seem to get above 38 percent. In a three-way race with no clear frontrunner, everything depends on who actually shows up to vote and how the second round breaks.
